We appreciate the opportunity to submit our proposal to provide construction materials testing services
for the above referenced project for the City of Columbia Heights.
Our Understanding of Project
This project is located on various streets throughout the City of Columbia Heights. The project is broken
up into a street rehabilitation project as well as a bituminous surfacing project. The Projects include new
granular subbase with geotextile fabric, new aggregate base, new concrete curb and gutter, sidewalk and
driveways, spot sidewalk replacement, milling of existing streets and new bituminous surfacing. The
project has municipal state aid funding and will follow the SALT Schedule of Materials Control.

This proposal is based on our review of the documents described below. If the project changes from the
information provided in these documents, we may have to submit a revised scope of services and cost.
• Project plans and specifications prepared by The City of Columbia Heights dated
March 29, 2016.
■ Discussions with you.
Project Overview
This project is a City of Columbia Heights project with State aid funding. Projects that are constructed
with State aid funding are required to perform Quality Control and Quality Assurance (QC /QA) testing in
accordance with the Minnesota Department of Transportation's (MnDOT's) SALT Schedule of Materials
Control. Personnel with MnDOT certifications must complete the monitoring and testing. Braun Intertec
will perform the QA field testing on the project for the items listed in our scope and as shown on our
construction materials testing cost estimate. The contractor will be responsible for performing all of the
required QC testing and submitting all the documentation upon completion of the project. An audit of

Concrete
The concrete testing for this project will consist of the following:
■ Perform slump, temperature and air content tests on the plastic concrete prior to placement.
■ Cast 4 -inch by 8 -inch cylinders for compressive strength testing.
■ Laboratory compressive strength testing of cylinders.
■ Develop the Weekly Concrete Reports for the Project Engineer's review and their submittal
to MnDOT's Concrete Office.
■ Concrete batch plant inspections will be performed by MnDOT Metro Inspections.
Bituminous
The bituminous testing for this project will consist of the following:
■ Collect one verification sample per mix per day of production. Perform quality assurance
tests on these samples which include rice specific gravity, asphalt content, extracted
aggregate gradation, gyratory density, coarse aggregate angularity, fine aggregate angularity,
and thickness and density of pavement cores.
■ Randomly determine and mark pavement core locations.
■ Observe the contractor coring and core testing in accordance with MnDOT's specifications,
which include watching quality control personnel weigh the cores at their laboratory.
■ Bituminous batch plant inspections will be performed by MnDOT Metro Inspections.
Reporting and Project Management
Test results will be issued for the project as the various tasks are performed. If, at any time, there are
failing tests or we observe construction processes which do not appear to be in accordance with the
plans and specifications or MnDOT Schedule of Materials Control, we will notify the engineer's
representative and any others that we are directed to notify.
After the project is completed, we will issue a final report. The report is compiled to meet the
requirements for the project audit. The report will include the following:
■ Complete testing roster of Braun Intertec employees conducting testing on this project.
■ Completed MnDOT Materials Certification Exceptions Summary for items tested by Braun
Intertec.
■ Completed Preliminary and Final Grading and Base Report.

Additional Services and Overtime
It is difficult to estimate all of the services, and the quantity of each service, that will be required for any
project. Our services are also directly controlled by the schedule and performance of others. For these
reasons, our actual hourly or unit quantities, and associated fees, may vary from those reported herein.
If the number of hours or units ultimately required exceed those assumed for purposes of this proposal,
they will be invoiced at the hourly or unit rates shown in the attached tabulation. If services are
ultimately required that have not been identified or described herein, they will be invoiced in accordance
with our current Schedule of Charges. Prior to exceeding our estimated fees, however, we will update
you regarding the progress of our work and notify you in the event it appears we will exceed our
estimated fees; any fees associated with additional services will be summarized in a Change Order and
submitted to you for review and authorization.
This proposal was also developed with the understanding that the scope of services defined herein will
be required and requested during our normal work hours of 7:00 am to 4:00 pm, Monday through Friday.
Services that we are asked to provide to meet the project requirements or a contractor's construction
schedule outside our normal work hours will be invoiced using an overtime rate factor. The factor for
services provided outside our normal work hours, or on Saturdays, will be 1.25 times the normal hourly
rate for the service provided. The factor for services provided on Sundays or Legal holidays will be 1.5
times the normal hourly rate for the service provided.
General Remarks
Braun Intertec appreciates the opportunity to present this Proposal to you. Please sign and return a copy
in its entirety.
The proposed fee is based on the scope of services described and the assumptions that our services will
be authorized within 30 days and that others will not significantly delay us beyond our proposed
schedule.

2.1 We will provide the services specifically
described in our Agreement with you. You
agree that we are not responsible for services
that are not fairly included in our specific
undertaking. Unless otherwise agreed in
writing, our findings, opinions, and
recommendations will be provided to you in
writing. You agree not to rely on oral findings,
opinions, or recommendations without our
written approval.
2.2 in performing our professional services,
we will use that degree of care and skill
ordinarily exercised under similar
