Re: Proposal for a Preliminary Geotechnba|Evaluation
New City Hall

Columbia Heights, Minnesota
Dear Mr. Hansen:

Braun !ntertecCorporation respectfully submits this proposal to complete opreliminary gentechn(ca|
evaluation for a new City Hall building located sd590 4Oth Avenue NE. Braun |nterten performed o
geotechnioe| evaluation furthe library immediately west mf the planned City Hall site (Braun |n1ertec
Project B1402193 dated July 22, 2015). The subsurface conditions on the library site consisted of
significant amounts of uncontrolled fill overlying swamp deposits, Due to unfavorable subsurface
conditions, the library was supported on driven piles.
Prior to our involvement with the library project, wa understand that some remedial excavations were
conducted |n the area east of the library. The City of Columbia Heights would like tn evaluate whether m
new City Hall building could be supported on a shallow foundation system east of the library, as opposed
to a deep foundation system that was required for the library. As this project is|n very preliminary
stages, specific details regarding the design of the building have not been developed. We anticipate the
building would be a 1- to 2- story building, with a slab-on-grade. We anticipate that less than 3 feet of cut
pr fill would be required tu reach final grades.
The purpose of our preliminary geotechnical evaluation will be to characterize subsurface geologic
conditions at selected exploration locations and evaluate their impact mn the design and construction of
a new City Hall building and to specifically determine if the proposed building can be supported ona
shallow spread footing foundation system.
The following tasks are proposed to help achieve the stated purpose. If unfavorable or unforeseen
conditions are encountered at any point during the completion of the tasks that lead usturecommend
an expanded scope of services, we will contact you to discuss the conditions before resuming work

Site Access, Staking and Utility Clearance
The site is currently being used for laydown and staging for the Library construction. We have therefore
budgeted to use a truck - mounted drill rig to access the site.
We will stake prospective subsurface exploration locations and obtain surface elevations at those
locations using GPS (Global Positioning System) technology. For purposes of linking the GPS data to an
appropriate reference, we request that you provide CAD files indicating location /elevation references
appropriate for this project, or give us contact information for the consultant that might have such
information.
Depending on access requirements, ground conditions or potential utility conflicts, our field crew may
alter the exploration locations from those proposed to facilitate accessibility.
Prior to drilling or excavating, we will contact Gopher State One Call and arrange for notification to the
appropriate utility vendors to mark and clear the exploration locations of public underground utilities.
You or your authorized representative are responsible to notify us before we begin our work of the
presence and location of any underground objects or private utilities that are not the responsibility of
public agencies.
Penetration Test Borings
As requested, we will drill 4 standard penetration test borings for the building. Based on previous work
on the site, we anticipate the borings may need to extend to depths of 50 feet or greater to extend
through fill and organic soils. Based on these estimates, we are assuming the western -most borings will
be extended to extend to a depth of 55 feet, while the eastern -most borings will extend to estimated
depths of 25 feet. We plan to extend the borings 5 to 10 feet into competent; natural soils, and may need
to modify the boring depths or termination criteria based on our findings while drilling. As discussed with
Brett Baldry of ICS Consulting, Inc., for this preliminary evaluation, deeper borings are not to be
performed to evaluate design of a deep foundation system. We have budgeted to complete the drilling
work in 13 hours; we anticipate that the 4 borings can be completed within this timeframe unless
conditions are significantly worse than our previous borings indicate. If conditions are worse than
expected, we will contact you prior to completing additional work.
If groundwater is encountered in the boreholes, the depth where it is observed will be recorded on the
boring logs.
Environmental Screening
Given the historical use of the site as a dump and the recent cleanup actions conducted, we recommend
that during advancement of the geotechnical soil borings, an environmental field technician monitor the
subsurface materials encountered. Samples for photoionization detector (PID) headspace analyses will be
collected at regular intervals to the termination depths.' In addition, the soil will be observed for visual
and incidental olfactory indications of contamination.

Our field observations will be documented on the soil boring logs. In the event that indications of
contamination, such as odors, staining, elevated P0readings or debris are encountered, we will contact
you to discuss potential chemical analysis of the sample interval. VVe have not included costs for chemical
analysis in this cost estimate. However, unit rates for applicable analytical parameters are provided
Borehole Abandonment
Minnesota Well Code requires sealing of any boring or core that encounters groundwater and is either
greater than 25 feet deep or penetrates a confining layer. Based on the intended exploration depths and
the history of the site, we have budgeted to seal each boring, 160 linear feet, with grout and prepare
associated sealing records.
Sample Review and Laboratory Testing
Soil samples will be transported to our laboratory, where they will be visually classified and logged by a
geotechnical engineer. To help classify the materials encountered and estimate their engineering
properties, we have budgeted to perform 6 moisture content tests, 4 mechanical analyses (through a
#200 sieve on|y), and 2 organic content tests.
Reporting
Data obtained from the borings and laboratory tests will be used to evaluate the subsurface profile and
groundwater conditions, perform engineering analyses related to structure design and performance and
prepare a report, including:
• A CAD sketch showing project components, limits, and exploration locations.
• Logs of the borings describing the materials encountered and presenting the results of our
groundwater measurements and laboratory tests.
• A summary mf the subsurface profile and groundwater conditions.
• Discussion identifying the site conditions that will impact structure design and performance,
qualifying the nature of their impact, and outlining alternatives for mitigating their impact.
• Discussion regarding the reuse wf on-site materials during construction and the impact of
groundwater onconstruction,

support, if applicable, and the selection, placement and compaction of excavation backMU

■ Preliminary discussion of foundation support options and feasibility of supporting the
structure on shallow foundations. (We have not budgeted to evaluate deep foundation
alternatives, as we understand that the City will not move forward with this project if deep
foundations are required.)

request, the report can also be sent to additional project team members.

We will furnish the services described in this proposal for an estimated fee of $9,585. A tabulation
showing hourly and /or unit rates associated with our proposed scope of services is attached.
Our work may extend over several invoicing periods. As such, for work that is performed during the
course of each invoicing period, we will submit partial progress invoices.
Additional Costs
If analytical samples are necessary, we will contact you for authorization. Sample analysis will be at the
costs provided below.
Analytical Testing - Standard Turnaround Time (5 to 8 business days)
Volatile Organic Compounds (VOCs)
$155 /sample
Polynuclear Aromatic Hydrocarbons (PAHs)
$213 /sample
8 RCRA Metals
$115 /sample
Gasoline -Range Organics (GRO)
$48 /sample
Diesel -Range Organics (DRO)
$60 /sampie
Asbestos Content using PLM
$30 /sample
We anticipate the field exploration can begin within approximately 2 to 3 weeks of written authorization;
the field exploration will take a day to complete. Sample classification, laboratory testing, engineering
analyses and report preparation will likely take an additional week. We will pass along results, however,
as they are obtained and reviewed.
If our proposed scope of services cannot be completed according to this schedule due to circumstances
beyond our control, we may need to revise this proposal prior to completing the remaining tasks.
