Dear Kevin,
Walters Recycling and Refuse, Inc. is pleased to present the attached proposal for Trash, Recycling, Compost, Bulky Item
Collection Services and Cart Management for the City of Columbia Heights. Walters has been servicing our customers and
communities since 1988 and would be honored to partner with the City to take your collection services to the next level just
as we have with some of your neighboring cities. We are proud to have been voted as Minnesota’s Best 2021 Gold winner for
Best Trash and Recycling Hauler by Star Tribunes Reader’s Choice and are excited to bring the same dedication and
excellent service to the City, and residents.
We believe our value-add proposal knocks the ball out of the park in terms of helping drive the health of the community and
the environment as well as environmental conservation and sustainability. A few highlights that we will dive deeper into in
the proposal include is our best-in-class technology that will enhance customer service while providing City administration
with valuable information to drive increases in all types of recycling and provide excellent communication with the City and
its residents. We are excited to be launching a new app that allows the residents to register and receive service notifications
and reminders while also allowing residents that are not as technologically savvy, to receive phone call reminders. Another
is our world-class customer service department staffed with live and well-trained operators, which is unique in this industry.
All of these are compelling differentiators that will enhance your goal to be an environmentally healthy community.
Finally, we are a locally based, family-owned business that has the experience and scale to service the needs of Columbia
Heights today and into the future. We invite you to visit our facilities at your convenience. We are just north of you near the
Anoka County Airport in Blaine, ideally located to service Columbia Heights. We will introduce you to the team and an
account manager we will assign to service the needs of the City.
Thank you again for the opportunity to provide you with the enclosed proposal, and feel free to contact us if you have any
questions.
Sincerely,
Jeff Newsom

Qualifications
General Management
We believe we are ideally suited to become the partner of choice for the City of Columbia Heights and
are confident that you will find our capabilities second to none, including the large national competitors.
Overall, we are prepared to service the City as outlined in the RFP and certify that we agree to all the
Contractor Required Services as outlined in the RFP. Details as needed, will be outlined in our
proposal. As an added benefit, we are a locally based and family-owned business with the tagline, “Big
enough to get the job done, small enough to care”. We are located just north from the city near the
Anoka County/Blaine Airport so are well prepared to efficiently serve the community.
Walters strongly believes in a balance between work and family. This philosophy has contributed to
Walters having a staff of nearly 140 dedicated professionals with one of the lowest turnover rates in the
industry. Our staff of well-trained and experienced employees is ready and able to serve the needs of
the City of Columbia Heights.
While we provide solid waste and recycling services, we are really in the client service business. Unlike
most of our competitors, we have a team of well-seasoned and experienced full-time customer service
staff employees ready to assist. Our customer service philosophy has been to have a live person answer
the phones from 8:00 a.m. to 5:00 p.m. Monday through Friday. We understand the importance of

personal relationships.
We are located in the city of Blaine at 2830 101st Ave N E., ideally suited for the short drive to
Columbia Heights. Our office and maintenance facility were recently expanded and remodeled to
include a new state-of-the-art phone system, computers, dispatch, and maintenance facility. We
encourage you to visit at your convenience.
As a family-owned and operated company, the City will have ready access to our management and
operational personnel as well as the ability to build a relationship with the owners of Walters.
Our Mission: We stand to be a pillar of dependability in the communities we serve by providing safe,
simple, and reliable service.
Our Vision: To be recognized as the premier environmental services provider in the Midwest.
Our Business Principles: Walters is committed to sound ethical and moral business principles. They
are:
• To treat all employees, customers, vendors and the general public with dignity and respect at all times.
• To conduct our business affairs with honesty and integrity.
• To provide our customers with friendly, efficient, affordable, and safe service.
• To provide a safe and secure working environment for our employees.
George Walter, Owner/Greg Walter, Owner.
George and Greg have a combined 80 years of experience in the waste and recycling industry.
They grew up working for Walters Disposal, their parents’ company, until the company was sold in
1983. After working for four years for the nation’s largest publicly traded waste and recycling
company, George and Greg formed Walters Recycling & Refuse in 1988. Today, 34 years later, we
employ nearly 140 people and are a vital part of the communities we serve.
Mike Moroz, President/CEO. Mike joined the Walters team in January 2014 and brings over 30 years
of organizational leadership, business transformation, strategic planning, and decision-making
experience. Prior to Walters, Mike was President of Archway Marketing Services for over eight years
and prior to that, was General Manager of Target Direct, the operating division of Target Corporation
responsible for launching target.com, fields.com, and other direct to consumer initiatives.
Matt Holland, Director of Operations. Matt has been with Walters for over five years and brings a vast
amount of knowledge and hands-on experience to the company. Matt has experience both inside and
outside of our industry, most recently leading the operations of the local hub of the nation’s largest school
bus company, First Student. He leads the drivers and manages the overall operations of the company. He
is also responsible for our in-depth safety and training programs.
Justin Eylandt, Fleet Maintenance Manager. Justin is an integral part of the Walters team. He
supervises our outstanding team of mechanics and welders who maintain our fleet of over 75 residential,
commercial, and roll-off trucks.
Andrew Tortora, Customer Service Manager. Andrew is part of the Walters family and after growing
up around the business, brings a wealth of cross-functional knowledge and perspective on all our systems
as well as the need for integrated communication between all departments in order to dazzle our
customers.
Jeff Newsom, Director Sales, Marketing and Customer Service. Jeff will be your account manager
and brings over twenty years of sales, marketing, and account management experience. Prior to joining
the team in March of 2019, Jeff was the Director of Regional Sales for Farmer Brothers Coffee, and was

7 – RFP for City of Columbia Heights
responsible for the sales, operations, and account management of over 10,000 commercial accounts in the
Midwest.
In addition to the team above, our existing team of drivers, customer service reps and mechanics will be
supplemented with additional hires to ensure we provide world-class service for Columbia Heights. We
will ensure that we are not just adding new staff to the Columbia Heights team, but also move people
around to bring experienced professionals focused on the City.
Walters Recycling & Refuse, Inc. is prepared to provide the City of Columbia Heights with the services
required in the Request for Proposal. We have the knowledge, expertise, commitment, scale, and
financial strength to provide our customers with superior service from a local, family-owned company
which, from its inception, has been, and continues to be located in Blaine.
WHY WALTERS…Our greatest asset is our dedicated and professional team. Our added value to the
residents of Columbia Heights will be exceptional customer service from experienced individuals who
are committed to giving each resident personalized attention. We strive to hire,
train, and maintain a strong workforce that emulates a personal touch to each resident. We understand
that in today’s competitive business environment, there is a great demand for personal service. For this
reason, our telephones are answered by real people instead of a machine. We are also committed to
innovation and investments into technologies to improve the customer service experience. Walters will
be implementing a new app in the spring of 2022 which allows residents to check their service schedule,
identify how to properly dispose of or recycle items, and receive service notifications and updates.
WHY WALTERS…Our drivers are well-trained, safe, and courteous. Nearly 50% of our drivers have
been with Walters for seven years or more, with five drivers having over 20 years with the company.
To provide superior customer service to the homeowners on their route, our drivers will often walk up
and get the customer’s cart if they see it is not curbside during pickup day. Our drivers live by this
philosophy each day on their routes – we are in the customer service business.
Business Information
Financial Stability, Strength, and Performance
The Walter family has been in the industry for over two generations. George and Greg Walter followed
the footsteps of their parents’ company (Walters Disposal), which was established in 1956. Walters
Recycling and Refuse is an S-Corp and was established in 1988. We just celebrated our 34th anniversary
on March 1, 2022. George and Greg Walter started the business with just one truck and about 200
customers. Today, 34 years later, we have built the company into one of the top two largest independent
waste companies in the state, and in the top 100 in the United States. We have gone from a customer base
of 200 in 1988 to over 65,000 residential and over 5,000 commercial, industrial, and roll-off customers
today. We attribute this considerable growth to five simple, but important, concepts: Integrity; Quality
Service; Well-Maintained Fleet; Exceptional Customer Care and Environmental Responsibility.
We are uniquely positioned financially to service and grow with the City of Columbia Heights and have
the capacity to scale. The Company has no long-term debt (outside of a mortgage on our facilities), is
profitable and has tremendous long-lasting relationships with our bank, which positions us well to make
any investments needed to service and grow with you. If we are fortunate enough to be selected to
provide services on behalf of the City, we will be happy to confidentially share any needed financial
information.
Walters has had no litigation in the last five years that would impair our ability to service the City with
any company, partner, subcontractor involved in the venture, and/or any corporate officer. We have not
9
Item 1.
8 – RFP for City of Columbia Heights
failed to meet a contract, or contract obligation with any municipality, county, or other public entity. In
addition, Walters has never filed for bankruptcy nor been in receivership.
Walters is in the business of collecting multiple waste streams to include MSW (trash), Recycling,
Organics, Yard Waste, Bulky Item collection while also managing all aspects of the cart management
process including cart deployment, repairs, and warranty claims. Additionally, Walters owns and
operates a transfer station in Blaine.
Proposed Operations
We do not anticipate any deviations from the service standards outlined in the RFP document.
Cart Management and Bulky Item Collection
Over the last number of years, we have developed a robust and very efficient cart management
process including inventory management, cart deployment, repairs, and cleaning of carts. We
have a single owner of the process internally whose job is to manage inventory, procurement,
maintenance, and routing of delivery/pickup of carts and containers throughout the area. We
currently manage all aspects of cart management for all our municipal contracts and open
subscription markets which is currently over 65,000 residential customers. Regularly, we
execute very large deployments to residents (hundreds per day), mobile-home parks (often
1000+ carts per project taking 1-2 days) and cities (over 20,000 carts throughout Blaine in 3
weeks). Recently, we deployed over 2400 carts in the city of Spring Lake Park in 4 days. If we
are fortunate enough to partner with Columbia Heights, we are confident our experience in cart
management will be seamless to the residents.
As far as maintenance is concerned, we have multiple acres of paved yard for storage and a 2-
person full-time cart maintenance crew who repair, wash, scrap, and process warranties on carts.
We have sufficient space, personnel, and capacity to service the needs of the City.
As it relates to cart distribution and bulky item collection, we have two full-time drivers with
new state-of-the-art cart delivery/bulky item pickup box trucks who have the scalability to
service the incremental needs of Columbia Heights. These trucks have been designed internally
by our operations and fleet maintenance teams, specifically for efficient
delivery/exchange/pickup of carts and bulky items (Routeware tablets, tail and side lift
gates/doors, strapping hardware located throughout the truck, low entry, etc.).
Walk-Up Collection Services
We are happy to provide walk-up service to qualified residents for no additional cost to the resident. We
ask that the City make the final decision on whether a resident is qualified for this level of service.
Services at City Buildings
We are happy to provide, at no charge to the City, the services as outlined in the RFP.
Comingled Yard Waste and Organics
Yard waste and organics will be collected as comingled as outlined in the RFP. We do not anticipate
any deviations from the requirements as outlined in the RFP. We will also work with the city and
compost facilities to identify additional material that can be added to the list of acceptable items
collected.

employees by achieving greater than or equal to the estimated availability of female talent in the
marketplace.

12
Item 1.
11 – RFP for City of Columbia Heights
drivers out of a total 70 (8.5%). This is significantly above the 1% industry average in the
waste and recycling industry and growing. We are also very proud of the fact that our
compensation plan is equitable for all categories of team memb ers.
Customer Service and Other Community Relations Services
Our call center is at our main office at 2830 101st Ave NE in Blaine
Hours of live call center operations are currently 8:00-5:00 M-F but we can be flexible with
Columbia Heights needs.
Methods to support our customer service representatives to train them on
Columbia Heights- specific service elements and contract standards:
We pride ourselves on providing excellent customer service, living our philosophy that we are in
the customer service business. All customer service staff are cross trained to handle each
individual call which avoids the constant transferring of a call from one individual to another.
Due to the culture of our company, we have experienced a very low turnover in Customer
Service Representatives. In addition, we record all CSR incoming calls and can refer to these
calls, as necessary.
Our Customer Service On-Boarding Program is very rigorous and comprises the following topics
across a two-week period before the new rep is allowed to begin taking live calls with customers:
1) Walters Company History (Week 1)
2) Walters Waste and Recycling Programs (Week 1)
3) Introduction to the Waste and Recycling Industry (Week 1)
4) Top Reasons Customers Call (Week 1)
5) Who's Who at Walters (Week 1)
6) New Residential Customer (Week 1)
7) Bulk Item Pick-Up (Week 1)
8) Billing, Invoices, A/R and Residential Collections (Week 1)
9) Residential Cancellation (Week 2)
10) Compost (Week 2)
11) Organics (Week 2)
12) New Commercial Customer (Week 2)
During the first several weeks, or as needed during the transition stage, we will offer one of our
Customer Service Representatives to office at the City to assist with any incoming customer
calls. After this initial period, we will appoint a lead Customer Service Representative to
13
Item 1.
12 – RFP for City of Columbia Heights
monitor all incoming calls and reporting requirements.
We will also assign an account manager to “own” the relationship with Columbia Heights and be
the day-to-day Senior-level contact at Walters with authority to make decisions that are in
the best interest of the residents. In addition, we will provide the direct phone numbers and
email information for the entire management team at Walters so that ongoing communication
and a true partnership with the City is established.
Communication is vital to a good partnership with a City and its residents. Residents
will have access to communicate with us or receive notifications through a variety of
methods including email, text, various social media platforms (Facebook, Instagram), our
website, the city’s website, and voicemail. Additionally, residents can download our app
and/or sign up for service notifications and alerts. Residents will have the ability to
choose how they want to receive service notifications and alerts through emails, text
messages, or phone call notices.
Any customer service-related issues will be handled professionally by our customer service staff.
We have the ability to electronically log and report on all issues and can provide the outcomes of
any issues to the City.
Methods to link customer complaints to improved route services:
We utilize the latest release of AMCS’ Tower ERP system, a powerful customer and route
management software. This software, along with the integration of Routeware,
allows Walters to provide the highest efficiency and productivity levels available in the
industry. Each customer location is geo-coded in Tower which allows us to determine the
exact time our driver was at the location and whether the container was serviced and/or
missed or skipped. It also allows our drivers to send critical information back to the office.
All of this information is live and contained in the service locations account in Tower,
which is accessible by our entire customer service and operations staff.
Snowbird Policy
If the City agrees, residents who will be away from their home for a period of 1 month or longer
simply need to call our office to stop their services. When they return, the customer can then call
our office to re-start their services again.
Contingency Plan
We would be arrogant if we thought there could be no issues that surface during the transition or
contract term. Issues are bound to arise. The key to success is in the response when issues do
arise. Three common issues and their respective contingency solutions include:
1) Employee Absenteeism – Team members get sick. It has happened in the past and the
risks have risen with the COVID-19 pandemic. We have rigorous COVID-19 procedures
in place and have not had a single issue with not servicing routes daily. However, this
does not mean we can let our guard down and we have entered a new way of doing
business to keep the team safe and able to service our customers. In addition to COVID-
14
Item 1.
13 – RFP for City of Columbia Heights
19 cleansing/disinfecting protocols, we plan for absenteeism by having Swing drivers
available to step in as needed. These drivers do not have daily routes but are proficient on
all pieces of equipment and can be assigned as needed. As further backup, our operations
management team has their CDL and know how to drive and operate the equipment. On
an emergency basis they can step in if needed.
2) Equipment Breakdown – due to their heavy usage garbage trucks break down. We have
several safeguards in place to ensure that when they do there is no risk of routes not
getting completed:
a. Spare trucks – we maintain several spare trucks that are used specifically when a
primary truck is out of service.
b. We have 2 state of the art service trucks that are deployed immediately to the
scene if a truck breaks down while on route. Our mechanics all have their CDL
and can assist as needed to get the truck back on route.
c. We have a very rigorous Preventive Maintenance program that we follow to do as
much proactive work as possible to minimize the number of breakdowns in the
first place.
d. When needed, we can seamlessly leverage our systems to peel off stops on routes
that might be impacted due to a breakdown and assign those stops to a “Helper
Route” with another truck to ensure daily routes are completed.
3) Consistent Problem Resolution – We have found that there have not been any consistent,
ongoing issues that have prevented routes from being completed. Generally, when an
issue has surfaced more than once we will work closely with City staff to find the root
cause of the issue and solve it for the long term. As individual issues do arise, we are
committed to responding immediately and fixing them. Please ask our references for real
world feedback on this.
Impact on Roads
Strategic Routing - Walters has worked with various cities to develop strategic routing plans to
minimize the road wear and tear created by trucks. If awarded this opportunity Walters’
operations staff would be willing to meet with the Columbia Heights engineers and street
maintenance personal to develop a plan tailored to the roads of Columbia Heights. We would
identify the older worn streets as well as any areas the City’s maintenance department has
identified as troubled areas. For these areas Walters will structure the routes so the trucks are
empty or as close to empty as possible when we run through these areas. For the problem areas
that are identified Walters will work with City staff as well as our drivers to develop a plan to
minimize or eliminate these issues. We have deployed a similar process successfully with three

Pollution Reduction and Environmentally Sustainable Initiatives
Walters is currently converting our fleet of diesel-powered engines over to Compressed Natural Gas
(CNG) powered engines. These CNG powered trucks run 30% cleaner than those that run on traditional
gasoline or diesel fuel. Carbon monoxide emissions are reduced by 70 to 90 percent and carbon dioxide
15
Item 1.
14 – RFP for City of Columbia Heights
emissions are reduced by 20 to 30 percent. Plus, even noise pollution is reduced, as CNG powered
trucks operate at an 80 to 90 percent lower decibel level than diesel fueled trucks. Residents love them.
In addition to converting our fleet to CNG powered trucks, Walters constantly investigates and is
dedicated to investing in alternative fuel and sustainability initiatives. A couple of examples of our
initiatives include converting to LED lighting in our facilities to reduce energy consumption and using
used motor oil to heat our maintenance shop. We also evaluate routes to ensure they are optimized to
run the most efficiently to reduce the amount of fuel consumed in our collection vehicles which reduces
our environmental impact. Paperless invoicing is another way we can help reduce our environmental
impact and we will encourage Osse residents to sign up for paperless invoicing to help us with this
initiative.
Public Education and Service to Residents
As you know, contamination has become one of the biggest challenges related to driving recycling
processing costs up since the China Sword initiative took effect in early 2018. Please see attached
several educational pieces we currently deploy around efforts to increase recycling, do it properly to
reduce contamination and a gentle reminder if you are not following the rules (an Oops Tag, for
example). If the City provides email addresses, we are also happy to coordinate and deploy email alerts
and content-rich messages to residents and businesses that drive increased recycling volumes and
increased recycling quality.
We will build a Columbia Heights-specific section on our website that details all pertinent
information residents might need to understand all topics related to the services we have been
awarded. See our website for the Blaine page accessed on the top navigation bar under the
“Blaine” tab. We will also assist the City in adding a page or link from the City website to
Walters’ website that provides residents information on how to do things like set up service,
change services, request a new cart, get items picked up, etc.
Also attached is a Recycling-focused coloring book that has been a big hit with schools and
communities that we work with. We are happy to have a member of our team attend community
and school events, as appropriate, to promote and educate kids and residents on the importance
of recycling and all the ways to do it correctly.
See also attached a page of examples from our social media efforts around recycling. We have
found that when partnering with municipalities who “like” and “share” these messages, the word
gets spread quickly. We are happy to work with the City to generate ideas on how to
communicate with residents productively and to avoid creating a negative relationship.
Public Service at Community Events
Walters has extensive experience in providing waste services at community events including fairs,
parades, rummage sales, and community events. We have worked with the city of Blaine in their Blazin
Festival where we provide trash and recycling services for the event. The North Oaks Women’s Guild
with their annual rummage sale and we provide them with trash and recycling services. The Boys
Scouts wreath clean up at the Fort Snelling National Cemetery where we assisted with cleaning up
40,000 grave sites which included hauling 10 – 30 yard roll off containers of wreaths in one day. The
biggest event we are servicing is the 3M Golf Championship. We have a multi-year agreement as the
sole trash, recycling, and organics service provider for the event.

Submitted Bid Conditions
Price increase assumptions:
The annual rate of increase for all of the bids submitted below are assuming and annual CPI increase of
3% per year. Actual increase will be based on the actual CPI: Urban Consumer - Garbage and Trash
Collection so that all parties involved have a fair and equal means to calculate annual increases.
Fuel/Energy Surcharge Table
Based on the volatility of fuel markets, Walters has defined a fuel/energy surcharge if Diesel fuel
exceeds $5.00 a gallon. The table below details an example of how fuel/energy surcharges would be
applied based on the market price of fuel Walters purchases. The market price will be determined 5
business days prior to the end of the month and will be communicated to the City if any surcharge will
be applied.

Surcharge % Applied to Invoice 1% 2% 3% 4% 5%
Alternative to Landfilling
Currently, there is no alternative to landfilling the waste from the City. The waste to energy facilities in
the area will not accept waste that is not generated in Ramsey, Washington, or Hennepin counties.

weekly fully automated curbside recycle collection with ASL trucks. We will utilize 96-gallon carts with
a yellow lid where residents should place all standard recyclables together, no sorting or bagging.
Please rinse cans, bottles and containers. Residents may request 64 or 35-gallon carts. Residents must
place their recycle carts at the curb no later than 6:30 a.m. on their service day.
We will provide monthly reports for recyclable materials to the City’s Recycling Coordinator.
Collection will not take place on New Year’s Day, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, and Christmas Day.
Yard Waste
Waste Management will provide weekly residential yard waste collection and will operate weekly fully
automated curbside yard waste collection with ASL trucks. Collection will take place from April 15 th
through the last full week in November (weather permitting). The city will supply each home with a 96 -
gallon yard waste cart. Residents who may have more yard waste than the cart will hold may use
36
Item 1.
compostable bags for additional material. Acceptable yard waste is leaves, grass clippings, sticks and
twigs under 4’ long and 2” in diameter, pinecones, acorns and garden & plant waste. Unacceptable
waste includes rocks, sod, dirt and large branches and tree trunks.
Organics
Organics will be picked up weekly. Customers will be provided a 35-gallon cart for organic waste.
Customers will be required to sign up for the program . Once they opt into the program weekly service
occur at their residence. All residents will be required to pay f or the service.
Bulk
Bulk service will be preformed in either a rear load truck designed to pick up trash items (i.e. couches,
furniture and household junk) or a straight truck designed to pick up recyclable items (i.e. electronics,
appliances, mattresses). Collection will occur on the customers service day. Customers will need to report
collection at least 24 hours prior to collection.
Carts
Carts will be operated out of our Maple Grove facility. The facility has the capacity to store, wash and launch
carts to the city. Carts will be delivered, repaired, or exchanged on their service day. Customers will need to
communicate issues to WM at least 24 hours before delivery.
Safety: A Core Value for Waste Management
It is our duty to take every sensible step to prevent injuries in the workplace and return our employees
home safely every night. Likewise, Columbia Heights and all of the communities we operate in depend
upon us to safely collect, process, and dispose of their wastes while being mindful of our actions in their
neighborhoods to protect the environment that we share.
Therefore, safety is not just a priority for Waste Management -
because priorities often change - safety is a core value for our
company. We understand the magnitude of the responsibility we
have and strive to confirm that each task, piece of equipment, and
company policy and procedure reinforces safe actions and
behaviors.
Providing the safest possible service starts wi th our employees and establishing a culture for them that is
grounded in safety. We do this through:
37
Item 1.
• Hiring the Right Employees: Our diligent pre-employment screening process includes a
comprehensive background check, fingerprinting, and drug testing. All candidates and employees
are subject to Waste Management’s Drug and
Alcohol-Free Workplace Policy, which includes
regular, ongoing screenings for employees who
operate company vehicles.
• New Hire Training: Regardless of prior relevant
experience, all new drivers participate in new hire
training at one of our regional Driver Training
Centers. Through this two-week immersion training
experience, drivers learn safety rules, procedures,
vehicle inspections, saf e lifting, and DOT required
safety curriculum. In total, each newly hired driver
undergoes more than 80 hours of training both in
classrooms and behind the wheel with an
experienced driver.
• Ongoing Training: Every morning, each of our
drivers attends “tailgate” meetings where relevant
and time-sensitive safety topics are often
discussed. Monthly safety training series are also
held and provide employees additional time to go
in-depth on new or key safety topics. Observation
behavior assessments are conducted regularly by
route managers and driver trainers and provide on-
the-job assessments to evaluate driver knowledge,
operating behaviors, and compliance with safety
rules and best practices.
Waste Watch ®: Collaborating with Law
Enforcement for Safety
Serving the same locations each week allows
Waste Management drivers to become familiar
with their routes and areas. Our Waste Watch
program leverages this advantage by formally
teaching our drivers how to observe and report
suspicious activity or an emergency situation to
law enforcement.
Waste Watch-certified drivers participate in a
formal training program administered in
collaboration with local public safety and law
enforcement officers. Over the past decade, Waste
Management drivers throughout the U.S. and
Canada have reported suspected crimes and
assisted with emergencies caused by car crashes,
house fires, and pedestrian accidents.
38
Item 1.
Industry-Leading Safety Technology
Our fleet’s technology needs are specific to the services we perform, requiring us to custom develop and
implement advancements based on what matters most to Waste Management - our partners and
customers and our ability to deliver safe and efficient collection services with outstanding customer
service.
• DriveCam®: One of the safety innovations onboard
our trucks, DriveCam goes beyond traditional
dashcams by pairing machine vision with artificial
intelligence to identify risks as they occur on the
road and respond to the driver with real-time
coaching. DriveCam is mounted on the windshield
of the interior cab with cab-facing and road-facing
cameras. When an unsafe condition is detected,
such as critical following distance, lane departure, or
imminent collision, the device visually and audibly
alerts our drivers, providing an opportunity for self -
correction.
• Back Up Cameras: Our trucks have back up cameras that provide a view of the area behind the
truck whenever the truck is in reverse. This reduces the potential for backing accidents and
enhances pedestrian safety.
• eRouteLogistics®: eRouteLogistics software on each trucks’ onboard computing system takes
into account traffic patterns in the community through GPS – giving us the ability to modify routes
in real time so our trucks avoid congested areas or ongoing community events.
Additionally, all Waste Management trucks come standard with safety features such as electric heated
rear view mirrors, BusBoy mirrors for unrestricted views of the area in front of the truck, side floodlights to
illuminate both sides of the truck, and heavy duty disc brakes that exceed all applicable Federal Motor
Vehicle Safety Administration requirements.
Safety: A Commitment to Our Customers and Our Employees
There may be no other consideration as important as s afety when selecting a service provider for your
home, your place of work, or your community. Without a doubt, safety matters. It is no surprise that after a
tragedy most will say that as long as their family is healthy and safe, nothing else matters - mat erial items
can always be replaced.
At Waste Management, we all recognize safety as a core value - from our local District Manager to the
drivers, mechanics and staff who represent each district. With a constant focus on and meaningful
investments in training, technologies, maintenance and continuous improvement, we will deliver safe and
reliable collection services that protect the cities we serve, the people we employ and the environment we
share.
39
Item 1.
Industry-Leading Onboard Technology
Waste Management i s committed to continuously
investigating and investing in technologies. In accordance
with this philosophy, a decade ago Waste Management
created a dedicated team to research and invest in new
technologies. Our Corporate Venturing Team has become
the industry’s experts when it comes to experience in
evaluating new technologies and systems in the waste
industry.
Our fleet technology needs are specific to the services we
perform, requiring us to custom develop and implement
advancements based on what matters most to Waste
Management - our partners and customers and our ability to
deliver safe and efficient collection services with outstanding
customer service.
Onboard Computing System Provides Real-Time Driver Feedback
Our fleet of trucks for Columbia Heights is equipped with our onboard computing system (OCS), which
enhances communication between our operations and customer service teams. OCS replaced paper
route books with electronic route sheets that are updated in real time. Collection drivers see all stop s and
service tickets on their touch screens, which can be updated remotely and in actual time by our route
managers and dispatchers. Drivers use their OCS to log completion of each service performed. OCS is
also a key tool for noting and communicating rou te exceptions such as blocked containers, extras, and
contamination.
The primary benefits of OCS are:
• Service exceptions: When a driver encounters a condition that prevents providing service or
requires a service beyond emptying a container, such as remo ving extras and noting
contamination, he or she touches the “service exception” button, which triggers an “exception”
pick list on the display. Drivers touch the
role containing the appropriate service
exception.
• Proactive Customer Communication:
Drivers d ocument any issues associated
with attempting to service the customer
account, including carts not being out,
blocked access or ancillary pickups. This
allows us to proactively address issues with
our customers and prevent inconveniences,
such as a missed collection.
40
Item 1.
Technology for Efficiency, Communication, Safety
Our OCS is complemented by the following industry-leading software and technology for real -time
routing, dispatch communication, and safety:
• eRouteLogistics®: This mapping and routing software system is used to develop and modify
routes that takes into account traffic patterns in the community, vehicle capacity, location of
disposal sites, and travel times to create the most efficient routes possible.
• Plan Versus Actual (PvA) Technology: This software identifies routes that may be running
behind a typical schedule that customers are accustomed to, enabling Waste Management to
proactively redistribute routes to prevent missed or late pickups.
• Onboard Computer System Dispatch (O CSD): This in-office software connects dispatch and
route management to the driver’s OCS. Modifications are made in real -time and instantly appear
on drivers’ tablets so that any potential for service disruption is eliminated.
• DriveCam®: Each Waste Management truck cab is equipped with a forwa rd-facing camera
constantly recording everything that happens. Whenever there is a sudden movement, such as
hard braking, swerving, or a collision, the
camera automatically saves a 12-second
section of video. Once an event is
captured, information is sent to Waste
Management route managers for
performance coaching with the driver.
• Back Up Cameras: Our trucks have
back up cameras that provide a view of
the area behind the truck whenever the
truck is in reverse. This reduces the
potential for backing accident s and
enhances pedestrian safety.
Leading Safety with Onboard Technology Advancements

State-of-the-art trucks alone are not enough to meet
expectations. Through our comprehensive operations
framework, Service Delivery Optimization (SDO), we
harmonize the technology used onboard our trucks with our
logistics management processes, and the skills of our
drivers. With technology, processes and people working in
sync, we are able to maximize safety, customer service, and
efficiency while collecting Columbia Heights routes.

Material Specifications and Delivery Specifications
As a society, we know that recycling is important, it’s s omething that we really want to do, but in order for
recycling to make an impact, we have to recycle right. Today’s most successful and sustainable recycling
programs place emphasis on the value of the materials accepted – we must ask ourselves, does this
material have a viable market? If the answer is yes, we must also ensure the material we’re recycling is
properly prepared, clean, and free from contamination.
Our list of acceptable material is reflective of today’s market reality and includes only mate rials that meet
industry quality standards and have viable market demands. However, due to the length of our Contract
with Hopkins, it’s important to allow for the possibility that this list may need to be adjusted at some point
over the next 5 years. Contract language must support our collective need to make changes to material
accepted in order to respond to global market demands, as well as, protect the quality of material we
process.
Ability to Dispose of Materials Where There is No End Market
In order to successfully sell the material, we collect, we must remain flexible and responsive to market
shifts in material type and quality. The market has shown in the past few months, that there will be
extended periods of time, where the demand of for a s pecific material ceases to exist either temporarily or
permanently. These shifts in the market are uncontrollable events that our industry cannot influence.
Even the highest quality, contamination free bales of material must have a sustainable end -market in
order to truly be recyclable. In this type of scenario, Waste Management must have the ability to dispose
of materials for which there are a lack of buyers or markets.
The Current State of Recycling
The global recycling landscape is changing rapidly. We are all consuming differently than we were just 30
years ago. Much of what we purchase is now in single servings and we love pouches for our on -the-go
lifestyle. From food to electronics, we use a plethora of plastics, and we accumulate a lot of cardboard
boxes from online shopping. In the past 20 years we have seen a surge in curbside programs – both in
volumes and material diversity. At the same time, China accommodated the growth in recycling programs
and became the largest consumer of our recyclable ma terial. In fact, 30 percent of the world’s recyclables
were imported to China in 2016. Our recyclables fueled a growing Chinese economy, serving as a
valuable feedstock for everything from fleece jackets to shoe boxes.
But things have continued to change. China’s growth and bustling manufacturing operations had major
implications on their natural environment and in response they have set aggressive environmental goals
including major reductions in carbon intensity, restoring water quality, and implementing their own
nationwide recycling program. This also means that China is becoming increasingly selective about the
quality of materials they allow to be imported into their country and as of early 2018 they have begun
enforcing a new 0.5 percent contamination limit on imported recyclables in addition to Operation Blue
Sky, a screening effort to enforce their new policies. China has announced a plan to eliminate imports of
all post-consumer recyclables by 2021, and they appear to be taking steps to move down t his path.
As China moves forward with import restrictions, the global recycling industry has had to quickly adjust to
the new reality of recycling and this is no longer just a “China” market issue – this is a global market
issue. The bottom line is simple - regardless of where our recyclables go to be processed, the materials
we send to market must be clean and free from contaminants and there must be a demand for these
specific materials. Simply putting anything and everything into a recycling cart doesn’t count as recycling.
42
Item 1.
We are only offering a sustainable recycling program when the material we collect can be made into new
products and displace the use of virgin materials.
Impact of global market conditions on local recycling programs: China’s import re strictions have
eliminated the world’s largest market for mixed paper and mixed plastics, forcing recyclers to find a new
home for over 13 million tons of materials per year. This over-supply of material ultimately impacts all
curbside collection programs since paper and plastics are now competing for limited markets – and these
markets now have the ability to purchase only the highest quality of materials available with no
contamination. As the largest volume of material recycled, finding new markets for p aper is critical.
Extraordinary Language
In recent years, the recycling markets have shown us time and again that similar to oil, recyclables are a
volatile commodity in a global market. The value of the material we process and how much it costs to
transport and process that material can be impacted by everything from the world economy, political
sanctions and regulatory changes, to the introduction of new fees and taxes levied by government entities
or regulatory agencies, and by a host of extraordinary circumstances beyond the control of our Company.
In such circumstances, we are able to protect the continuity of curbside prog rams by maintaining our
ability to adjust rates to reflect the true cost of providing recycling collection and processing services.
What is Contamination?
Every day, Waste Management collects and sort tons and
tons of recyclables. However, nationally, on average, 25
percent of all items recycled are actually trash - things like
plastic bags, yard waste, hoses, and wires. This creates an
enormous problem called recycling contamination.
Recycling contamination happens when trash ruins
otherwise good recyclables. For example, food or liquids
placed in recycling will saturate paper and cardboard.
Once contaminated, these recyclables can no longer be
recycled and they become trash.
Why it is So Important to Recycle Right
In the midst of these challenges, we must remember to
pause and think about why we recycle. We recycle to
reduce our environmental impacts in a socially and
economically responsible way. Recycling reduces
greenhouse gas emissions, conserves resources, saves
energy, and reduces landfill usage. Contamination
threatens that by preventing thousands of tons of
recyclables from ever seeing a second life. This, in turn, negatively impacts value and demand of
recyclable materials, which dictates the growth of recycling infrastructure and the expansion of collection
programs at the local level. The sustainability of all recycling programs is dependent upon collecting high
quality recyclable materials free of unacceptable materials.
In order to overcome this, we must work in close collaboration with our customer partners –
municipalities, businesses, education institutions, and residents - to confirm that both new and
43
Item 1.
established recycling programs are sustainable given today’s realities. We must all work together to
develop local, effective solutions for this global problem.
Collecting materials is not the same as recycling them. It’s only when a material is recycled into
something else that we realize the economic and environmental benefits. Anything short of this, and we’re
simply creating a problem that results in a negative environmental impact. To allow our local recycling
programs to remain viable, workable operations, Waste Management has had to take proactive steps to
help our customers understand the new recycling paradigm and how local actions h ave global impacts.
Therefore, the previously stated recyclable specifications are of the utmost importance when educating
your residents/students/employees about what to recycle, but also about what not to recycle. Again, when
in doubt, throw it out.
The following list of items represents the current materials currently being accepted by Waste
Management as recyclables. This list may expand or contract due to market conditions.

BACKGROUND:
Project Budget update:
At the Special City Council meeting of March 23, 2022, the City Council approved the final plans and
specifications and authorized bidding for the buildout of the new City Hall. The bidding process is being
administered by the Construction Manager, Doran Special Projects (DSP). Prior to bidding, Doran reviewed
the scope of work based on plans and specifications and provided an updated estimate of the construction
costs at $5.3 – 5.7 million.
With rebidding, the City Hall Buildout has a total project cost of $6.165 million. While the project budget was
updated to reflect anticipated price increases due to inflation, pandemic induced supply chain disruptions,
and labor shortages, the bids received exceeded those estimates, including rebidding.
The attached budget sheet reflects the funding and updated project costs with all bids now received. The total
project development cost has a difference of (-)$1,004,169. This deficit will be funded through the General
Government Building Fund 411 or excess fund balances (various) or a combination thereof.
Construction timeline:
The new City Hall has been planned with a buildout of 6-7 months from start until move in. With the
condominium arrangement for the new space, the transference from the Developer to the City had several
requirements that need to occur, which include construction of the shell, developer provided equipment, and
a survey and recording with the County of the condo space. While these are now in process, the availability of
the built shell to begin our work has been delayed . It is anticipated that our construction will begin on or
around September 12. An estimated construction schedule of 6-7 months puts our move-in date to April 1 of
2023.

BACKGROUND:
Three concrete alleys were reconstructed with concrete pavement in 2020. In 2021, significant spalling was
found in varying degrees on the surface of each of the alleys. Concerned with the overall pavement integrity,
staff consulted with Braun Intertec to test and analyze each of the three alleys new concrete. A copy of that
report is attached.
Braun found the strength and hardness of each of the alleys meets or exceeds specifications. The defect, or
spalling, that is occurring now exists only in the upper 2-3 millimeters of the concrete. The reason for this
failure is likely due to the construction – either in water content or how they were finished, or both.
Staff has been meeting with and discussing how to remedy the surface defect of the alley. One option
presented by Braun Intertec was to do nothing – that the spalling would only occur in the upper most
surface of the alley. Staff did not feel this was a viable option due to the unknown time that spalling would
occur and due to the appearance of the surface the newly constructed alley. The other option would be to
remove the spalling segment by grinding 3 millimeters of the alley surface and then seal the new surface of
the alley. At the last meeting staff had with the contractor he agreed to concrete grind the alley. Due to the
inverse crown of the alley and rounded bottom at the center of the alley, a narrow grinding machine (39
inches wide) needs to be used. The contractor has indicated they will conduct the work this summer, but
possibly on short notice.

Re: Concrete Evaluation for Alleyway Pavement
637 38th Avenue Northeast
Columbia Heights, Minnesota
Dear Ms. Young:
Braun Intertec Corporation is pleased to provide this letter to report the findings of the concrete alleyway
pavement evaluation for three alleyways in Columbia Heights, Minnesota.
Background
It is our understanding that in 2020 the City of Columbia Heights performed reconstruction of some
concrete alleyways. It was reported to Braun Intertec that a number of those alleyways have developed
varying degrees of scaling. The evaluated scaling areas include the following three alleyways:
Alley 1: Madison Street to Monroe Street, 40th Avenue to 41st Avenue
Alley 2: Washington Street to Jefferson Street, 41st Avenue to 42nd Avenue
Alley 3: Madison Street to Monroe Street, 42nd Avenue to 43rd Avenue
These alleyways have a designed thickness of 8 inches and are not reinforced except where the alleyway
is tied into driveways. Concrete was supplied by Aggregate Industries and Cemstone. Compressive
strength results and paving mix design submittals were provided to Braun Intertec by the City.
Purpose
The purpose of this report is to assess concrete conditions and to identify potential cause(s) of deterioration.

Site Observations
The following data and samples were collected during a site visit on June 18, 2021.
Visual Inspection
Visual observations made in regard to scaling were documented in the attached Core Locations and
Distress Map. Alley 1 featured a relatively light amount of observed scaling compared to the other
alleyways. More widespread scaling was observed in Alleyway 2, and the most widespread scaling was
observed in Alleyway 3. Three cores were taken from each alleyway, and the locations of the cores were
determined based on visual observations.
Concrete Coring
Nine cores were extracted from the pavement in locations indicated on the attached Core Locations and
Distress Map. Table 1 below shows the core designations and course of testing for each core:

Paste & Carbonation
There are generally two distinct zones of paste:
1. The upper, surface zone that is carbonated, with a higher water to cementitious (w/cm) ratio
than the body of the concrete. This zone is up to 3 mm as measured in core samples C2, C6, and C8.
The w/cm ratios are 0.38-0.43 in C2, and 0.45-0.50 in C6 and C8. The paste is also generally soft,
with a Mohs hardness of 2.
2. The lower zone that reflects the subsurface body of the core. This zone is generally of good
quality paste that is dense with a lower w/cm ratio. The w/cm ratios are 0.35-0.40 in C2, and
0.40-0.45 for cores C6 and C8. The paste is non-carbonated, well distributed, and very hard
with a Mohs hardness of 4. Concrete typically has a hardness of Mohs 2-3.
Air Voids and Quality
1. The concrete is considered air entrained with an overall air void content ranging between
9-13 percent. This is higher than the specified air content of 5-8.5 percent.
2. Distribution of the air voids are poor in all of the observed samples. The presence of air voids
may be up to 12 percent in some localized areas. In other areas, air voids may be present at
as low as 2 percent. Large, irregular air voids (up to 1 cm) and smaller, coalescing air voids
are prevalent along the aggregate-paste boundaries. These poor air void characteristics are
typically more pronounced in the core that had more significant scaling.
Cracking, Surfaces, Other
1. On most of the samples, the relatively soft surface with a Mohs hardness of 2 has been worn
down, with much of the aggregate exposed and protruding on the top surface of the sample.
2. There is a broom finish on the concrete samples.
Discussion
Freeze/Thaw durable concrete requires three properties: a relatively low water-to-cementitious
(w/cm) ratio, a compressive strength greater than 4000 psi, and a well-distributed air void system.
All three properties are significant, but the w/cm ratio most-significantly impacts scaling potential.
59
Item 3.
City of Columbia Heights
Project B2104818

The w/cm ratio is the relative amount of water compared to cementitious materials in a concrete mix.
More water relative to cement will result in a reduced total volume of hydrated cement and a more
interconnected network of pores. Increased porosity provides more pathways for water and chloride
penetration. ACI Materials Journal 117-M54, “A Summary of Factors Affecting Concrete Salt-Scaling,”
indicates that low w/cm ratio concrete is most freeze/thaw durable and that the effects of the air void
system and compressive strength become prevalent at high water cement ratios.
Scaling is associated with small losses of the cement paste caused by the volumetric expansion of water as it
freezes and thaws in the paste. Chlorides or other deicing salts do not damage concrete; however, they do
exacerbate the damage to concrete that is not freeze/thaw durable by changing some of the properties of
water. First, deicing salts decrease the freezing point of water which causes the water in the concrete to
freeze and thaw at a lower temperature causing more cycles throughout the winter months. Water containing
10 to 15 percent dissolved chlorides from deicing salts has a reduced freezing temperature of 14 to -4 degrees
Fahrenheit. Secondly, it lowers the surface tension of the water which allows water to get into smaller pores,
increasing the saturation of the concrete. Deicing effects increase the frequency of freeze/thaw cycles and
creates more stress on the surface of the concrete during freezing and thawing cycles. Knowing this increases
stress at the surface, the quality of the concrete at the surface is critical to scaling resistant concrete. It is well
documented that scaling resistant concrete can be constructed following industry guidelines. This is evident by
other concrete flatwork near the site which does not exhibit scaling.
Low water-to-cementitious ratios lower the permeability of concrete, limiting the amount of water and
deicing chemicals that can enter the concrete. ACI 318 indicates that the water-to-cementitious ratio
should be less than 0.42 to resist freezing and thawing in a wet environment with deicing salts.
Additionally, the concrete requires an air void system to provide somewhere for water to expand into
which limits scaling damage. However, this is an effective strategy only if the entrained air voids are small
and well-distributed throughout the cement paste.
Conclusion
It is our opinion that scaling of the concrete core samples is largely due to the higher water to
cementitious (w/cm) paste that is present in the upper 3 millimeters of the concrete surface. The degree
of severity of the scaling issues is proportional to the elevated w/cm ratio observed in the concrete
surface. This increase water content at the surface may have been the result of; incorporating the bleed
water into the surface of the concrete when finishing, the addition of water to the surface to aid in
finishing or a possible rain event during the placing and finishing of the concrete.

The air voids systems were noted to be unevenly distributed and, although not ideal, this is considered
secondary as compared to the effects of the water-to-cementitious ratio.
Beneath the pavement surface, the concrete at depth is generally of good quality with a higher hardness
and lower w/cm ratio.
Repair Recommendations
Grind and Apply Penetrating Sealer
The relatively soft concrete surface can be ground down roughly 3 millimeters, so the harder, more
durable concrete is exposed. This will increase the porosity of the new concrete surface, therefore a
penetrating sealer, such as Prospec 100% Saline Sealer, should be applied to the surface of the newly
exposed concrete according to the manufacture’s instructions.

Re: Petrographic Evaluation of Concrete Pavement
Columbia Heights Alleyway
Columbia Heights, Minnesota
Dear Ms. Young:
Braun Intertec Corporation is pleased to provide this report of petrographic analysis of core samples taken
from the concrete slab of three different alleyways in Columbia Heights, Minnesota.
Purpose
The purpose of this investigation is to determine the cause(s) of scaling, and low compressive strength results.
Background Information and Sample Information
The alleyways in between Madison Street Northeast and Monroe Street Northeast, from 40th Avenue
Northeast to 43rd Avenue Northeast, in Columbia Heights, Minnesota is reportedly scaling. The concrete
slab was placed in June into August 2020. Previous testing by others also indicated that some of the 28-day
compressive strengths did not meet requirements.
On June 18, 2021, Braun Intertec visited the site and collected nine (9) cores for laboratory testing in three (3)
separate alleyways. These cores are 4-inch diameter cores and represent several areas of scaling, and a
control sample showing little to no distress. Three (3) of the core samples were selected for a full petrographic
evaluation that includes examination of a polished and a thin section, as well as a density test. The rest of the
cores were visually identified and recorded. The mix design details are provided in Table 1 below. Details of
the core samples are provided in Table 2.

Density, Absorption & Void Testing (ASTM C642)
Tested Samples
A portion of the concrete cores were tested to determine the relative density, absorption and volume of
voids in accordance with ASTM C642. The test portion of the samples are generally rectangular prisms
with total volumes of 460.0, 541.1, 513.1, and 630.1 cm3 for samples C2, C6, C8, and C9 respectively.
Reinforcing steel bars or wires were not observed in the tested portion.
Density Results
The results of the density testing are reported in Table 3. The sample absorbed 5.9, 6.0, 5.9, 6.0% water for
core samples C2, C6, C8, and C9 respectively, when submerged in water for 48 hours and boiled. The
saturated unit weight of the concrete was 145.9, 143.7, 142.8, and 143.2 lb/ft3 respectively. The ASTM C642
saturated unit weight test result is typically comparable to the design plastic unit weight of the concrete.

The core samples were initially cut down the middle to create two semi-circle halves. Approximately, the
upper 3 inches of the top of one half of the concrete was used to create a thin section, and the other half
was prepared for a polished section. The full-length polished section was prepared by grinding the cut surface
flat and polishing this surface with progressively finer diamond polishing discs. A thin section was also
prepared from the upper 3 inches of the sample. The billet for the thin section was vacuum impregnated
with blue dyed epoxy prior to sample preparation. The cut surface of the billet was also polished. A
photograph of the polished section, thin section and the polished billet are provided in Figures 10–12. The
prepared polished plane section and thin section were examined in accordance with the applicable sections
of ASTM C856, “Standard Practice for Petrographic Examination of Hardened Concrete,” using a stereo
microscope at magnifications ranging from 8 to 40x, and a polarized light microscope (PLM) at magnifications
of 25, 50, 100, 200, 400, and 500x. Our petrographic observations are provided below.
Findings and Discussion
A summary of the findings of our petrographic observations are presented and discussed below. Individual
petrographic observations of each core sample are provided at the end of the report.

Coarse Aggregate
The coarse aggregate is a crushed stone that is typically angular to subangular. It is comprised of
a light colored and red granite. The granites are generally medium to coarse grained and
comprised of quartz, K-feldspars such as plagioclase, orthoclase, microcline, as well as minor
biotite, chlorite and trace amounts of heavy minerals and iron oxides such as pyrite, ilmenite,
goethite and limonite. The granites are generally moderately to weakly altered with
chloritization of the biotite and sericitization of the feldspars. Microcrystalline quartz (Figure 28)
and myrmekite may be present in the aggregate.
The maximum observed particle size is 3/4, consistent of a #67 stone.
There is a low potential for alkali-silica reactivity (ASR) due to the presence of reactive silica
such as microcrystalline quartz.
The coarse aggregate is similar across all of the concrete core samples.
Fine Aggregate
The fine aggregate is a natural sand comprised of predominantly quartz, with some feldspars
(microcline, plagioclase, orthoclase), granites, quartzites, sandstone, siltstone, dacite,
limestone, and chert and chalcedony. The sand is sub to well rounded, and fairly well graded.
The sand is moderately altered, with much of the feldspars altering into sericite, and
secondary chert replacement (Figure 27). Other heavy minerals and iron oxides, such as
ilmenite and goethite are present in trace amounts.
There is a potential of alkali-silica reactivity (ASR) due to the presence of reactive silica such as
chert. Mitigation measures are present as indicated with the presence of Class F fly ash.
The fine aggregate is similar across all of the concrete core samples.
Paste, Carbonation
The binder is a Portland cement with Class F fly ash at approximately 20-25% replacement. The
maximum size of the cement grain observed is approximately 50 µm, with alite hydrations rims
of 5 µm. The paste is generally well hydrated, well distributed, with good paste content, and a
high amount of residual content and generally matches the mix design.

There are generally two distinct zones of paste (Figures 15–20):
1. The upper zone is the carbonated, with a higher water to cementitious (w/cm) ratio than the
body of the concrete. This zone is up to 3 mm as measured in core samples C2, C6, and C8.
The w/cm ratios are 0.38-0.43 in C2, and 0.45-0.50 in C6 and C8. The paste is also generally
soft, with a Mohs hardness of 2.
2. This is the lower zone that reflects the rest of the core sample. This zone is generally of good
quality paste that is dense with a lower w/cm ratio. The w/cm ratios are 0.35-0.40 in C2,
and 0.40-0.45 for cores C6 and C8. The paste is non-carbonated, well distributed and very
hard, with a Mohs hardness of 4. Concrete typically has a hardness of Moh’s 2-3.
Air Voids and Quality
The concrete is considered air entrained with an overall air void content ranging from 9-13%,
(Figures 23–26). This is higher than the specified air content of 5-8.5%.
Distribution of the air voids are poor in all of the observed samples. The presence of air voids
may be locally higher, up to 12% in areas, and in other areas, may be as low as 2%. Significant
voiding with large, irregular air voids (up to 1 cm) is also present, as well as some smaller,
coalescing, spherical air voids, often along the aggregate to paste boundaries. These poor air
void characteristics are typically more pronounced in the core that had more significant scaling.
Cracking, Surfaces, Other
The surfaces of most of the samples appear to have been worn down with much of the
aggregate exposed and protruding on the top surface of the sample. This surface is relatively
soft, approximately a Mohs hardness of 2.
There is a broom finish on the concrete samples.
Reinforcing bars, wire mesh, or concrete fibers were not observed in the cores.

Discussion
Scaling of the concrete core samples are largely due to the higher water to cementitious (w/cm) paste that
is present in the upper 3 mm of the concrete. This zone is carbonated, and generally quite soft, with a
Mohs hardness of 2. Concrete typically has a Mohs hardness of 2 to 3. This zone has a w/cm ratio that is
0.03-0.05 higher than the rest of the concrete. This is observed in Cores 2, 6, and 8, where the w/cm ratios
in this zone is 0.37-0.42, 0.45-0.50, and 0.45-0.50 respectively. The degree of severity of the scaling issues
in the observed cores also matches the w/cm, where the cores with the higher w/cm had more scaling
issues than the ones that are lower. It is likely that the higher w/cm ratios led to significantly weaker paste
causing the divots and scaling issues, as well as premature wear on the surface of the concrete.
Beneath this zone, the concrete at depth is generally of good quality that is hard, dense, well
consolidated, consistent, with a low water to cementitious (w/cm) ratio and matches the mix design.
The paste is very hard, with a Mohs hardness of 4.
The air content of the concrete is also considered high, with an overall air void content ranging from 9-13%
that is significantly higher than the specified content 5-8.5%. The air voids are generally small and spherical,
however is poorly distributed in several areas of the concrete core samples. Locally, the air content may be as
low as 2% and as high as 12% in some areas. Despite the inconsistency of the air voids, it is highly unlikely
that the quality of the air voids contributed to the scaling issues.
Conclusions
The following conclusions are based on the provided background information, our observations,
and our experience.
Softer, weaker, and a higher water to cementitious (w/cm) paste likely the primary reason for
the scaling issues of the concrete. The higher w/cm paste is generally up to 3 mm deep,
carbonated, and is 0.03 to 0.05 more in w/cm than the rest of the concrete at depth. The
increasing w/cm paste also correlates to the severity of the scaling issues.
The rest of the concrete at depth is of good quality, well hydrated, very hard, and matches
the mix design.
The air void content is higher than the specified amount, with locally poor distribution,
however, is not the likely cause of the scaling issues.

Sample Information Sample: C6
Sample Location: Alleyway 2: Alleyway on the 42nd Ave. NE. to 41st Ave. NE. block in
between Washington St. NE. and Jefferson St. NE.
Placement Date: June 2020
Reported Distress Observed: Widespread scaling
Mix Design: 3F52
Polished Section: Yes
Thin Section: Yes
General Observations
Initial Examination and Representative Sub-Samples Made:
Petrographic examination was based upon the core labeled as “C-6”. The core is 4 inches in diameter,
and approximately 8.65 inches long.
The sample was cut lengthwise to create a polished cross section for analysis on one half of the core.
Approximately, the upper 3 inches of the other half of the cut core was used to create a thin section. The
thin section, with dimensions of approximately 3 in x 2 in was first vacuum impregnate with blue dye
prior to sample preparation. The corresponding billets used to prepare the thin section were also
polished. The prepared polished plane sections, polished billets and thin sections were examined in
accordance with the applicable sections of ASTM C856, “Standard Practice for Petrographic Examination
of Hardened Concrete,” using a digital microscope at magnifications of 20, 30, 50, 100 and 200X and a
polarized light microscope (PLM) at magnifications of 25, 50, 100, 200 and 400X.
Surface Observations:
Top: Top surface is scaling, with many divots, as well partially eroded with much of the coarse
and fine aggregate particles exposed. Broom finish.
Bottom: On grade. Sandy gravels
Residual Surface Compounds:
None noted.

Aggregate
Coarse: The maximum observed particle size is 3/4 in, consistent of a #67 stone. The coarse aggregate is a
crushed stone that is typically angular to subangular. It is comprised of a light colored and red granite. The
granites are generally medium to coarse grained and comprised of quartz, K-feldspars such as plagioclase,
orthoclase, microcline, as well as minor biotite, chlorite and trace amounts of heavy minerals and iron oxides
such as pyrite, ilmenite, goethite and limonite. The granites are generally moderately to weakly altered with
chloritization of the biotite and sericitization of the feldspars. Myrmekite is also present in the aggregate.
Fine: The fine aggregate is a natural sand comprised of predominantly quartz, with some feldspars
(microcline, plagioclase, orthoclase), granites, quartzites, sandstone, siltstone, dacite, limestone, and chert
and chalcedony. The sand is sub to well rounded, and fairly well graded. The sand is moderately altered,
with much of the feldspars altering into sericite, and secondary chert replacement. Other heavy minerals
and iron oxides such as ilmenite, goethite are present in trace amounts. There is a potential of alkali-silica
reactivity (ASR) due to the presence of reactive silica such as chert. Mitigation measures are present as
indicated with the presence of Class F fly ash.
Paste
Depth of Carbonation: Carbonation of the paste ranges from 2-3 mm along the top surface.
Carbonation reflects the higher w/cm ratio paste at the top surface.
Air Content: Air entrained. Air contents range from 10-13%. Air voids are generally small
and spherical but are poorly distributed; some areas with <2% other areas up
to 13% air.
Paste Content: Good
Paste Hardness: Upper 3 mm: Mohs 2-3. Lower 3 mm: Mohs 4
Paste Color: The paste is light gray in color
Paste-Aggregate Bond: Generally good in areas not affected by coalescing air voids
Paste Luster: Within the concrete at depth, the paste has a sub-vitreous luster
Pozzolan Presence: Class F fly ash 20-25% replacement
Cracking: Rare
Secondary Deposits: Rare to none
Paste & Paste Hydration: The binder is a Portland cement with and Class F fly ash at approximately 20-
25% replacement. The maximum size of the cement grain observed is
approximately 50 µm, with alite hydrations rims of 5 µm. The paste is
generally well hydrated, well distributed, with good paste content, and a high
amount of residual content and generally matches the mix design. W/C(m) Ratio: Estimated at 0.40-0.45 at depth. Upper 3 mm is 0.45-0.50.
Portlandite: Rare fine crystallites of portlandite
Other: Concrete paste lower than 3 mm is very hard (Mohs 4). Concrete paste is
typically Mohs 2-3. Upper 3 mm of concrete paste is very soft resulting in
premature wear, exposing aggregate on top surface. Soft paste is likely due
to the higher w/cm ratio.
