RE: Proposal for Geotechnical Services
2011 Street Reconstruction
NTI Proposal P1052
We are pleased to submit our proposal to perform Geotechnical Services for the above
referenced project. The purpose of this study is to determine the soil and groundwater conditions
at this site and to prepare a geotechnical engineering report with appropriate design and
construction recommendations.
SCOPE OF WORK
The following is our proposed work scope based on your RFP.
We propose to mobilize a truck mounted drill to the project to drill two (2) standard penetration
soil borings advanced to a depth of twenty (20) feet and one (1) standard penetration soil borings
advanced to a depth of twenty five (25) feet (total of 65 lineal feet of drilling).
We assume the site to be accessible by a truck - mounted drill rig and there will be no obstructions
such as overhead utilities, excessively deep snow or stored materials preventing access to the soil
boring locations. NTI will contact the Minnesota "One -Call" system for clearance of public
utilities prior to start of drilling operations. We will make you aware of our field activities
before proceeding to the site.
Soil sampling in the borings will be performed at 2 -1/2 foot intervals to a depth of 15 feet with
additional samples obtained at 5 -foot intervals thereafter. Soil sampling will be performed in
general accordance with ASTM D 1586. A geotechnical engineer will visually classify field -
collected samples in accordance with ASTM D 2488. Each soil sample's color, relative
moisture, STP N- value, relative density, consistency and estimated compressive strength will be
documented on soil boring logs.
We will measure for the presence of groundwater or lack thereof when we complete each soil
boring. We will backfill the soil borings with soil cuttings or high solids bentonite grout to
comply with current Minnesota Department of Health Regulations.
We will also perform routine laboratory tests on selected soil samples, as appropriate. Upon
completion of the field and laboratory work, a geotechnical engineering report will be submitted.
The report will include the logs of the borings, location drawing and the results of the field and
laboratory tests. In addition, the report will include our engineering opinions and
recommendations regarding:

Columbia Heights, Minnesota
1. Estimated depths of poor soils, if any, to be removed at each boring location.
2. Groundwater depth at the time of drilling
3. Potential construction difficulties regarding excavation and backfill.
COST
We will perform the Geotechnical Exploration and Report for a lump sum fee of $1,300.
Additional drilling, if needed and authorized, will be invoiced at a rate of $14 /foot if performed
at the same time as the original borings.
SCHEDULE
To meet your bid schedule we have cleared a brief gap in our drilling schedule for Monday
February 28, 2011. In order to meet this schedule we require acceptance of this proposal before
the end of the business day on February 23, 2011. Unless delayed by reasons beyond our
control, we will submit our report to you on March 1, 2011.
OWNER'S RESPONSIBILITIES
The City shall paint the proposed boring locations on the pavement before utility locators are
called to the site on 2/24/2011. If traffic conditions necessitate flagmen the City shall provide
these people or incur an additional charge of $100 per hour.
ACCEPTANCE
Please indicate your acceptance of this proposal by signing on the signature block below, and
returning a copy to us. The attached General Conditions are an integral part of this proposal.
This proposal is effective until April 1, 2011.
We thank you for the opportunity of submitting this proposal and look forward to working with
you through both the design and construction phase of this project. If you have any questions
regarding this proposal please contact the undersigned at 763 - 433 -9175.
