Re: Supplemental Proposal for Geotechnical Services
Davis Lift Station and Norton Sewer
Nelson Road & North Frontage Road
Bozeman, Montana
Terracon Project No. 26185044
Dear Ms. Revis:
Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this supplemental
change order to provide additional geotechnical engineering services for the project referenced
above. The purpose of the additional proposed engineering services is to complete two borings
that could not be advanced during the initial mobilization and provide estimated fees for two
additional borings proposed within the railroad right of way associated with the proposed
horizontal bore crossing.
A. PROJECT INFORMATION
Site Location
ITEM DESCRIPTION
The proposed lift station is located east of the intersection of
Nelson Road & North Frontage Road in Bozeman, Montana. The
Location project includes utility installation to the south and east of the
proposed lift station.
Latitude/Longitude N 45.725745°, W 111.078953' (approximate)
Interstate 90 and existing railroad tracks are located to the south of
Existing Conditions the proposed lift station. Developed residential and commercial
structures are located near the areas of proposed utility installation.

Davis Lift Station Bozeman, Montana
July 24, 2019 Terracon Project No. 26185044
B. ADDITIONAL SERVICES
During the initial mobilization, two proposed borings, B-5 and B-6, were unable to be performed.
The location of B-5 had not yet been confirmed and the soil conditions encountered at B-6 were
too wet and soft to access with the drill rig. After a brief discussion with Mr. Jeff Heidner with
Sanderson Stewart, he indicated that both borings could be drilled at a later date when the location
of B-5 was finalized. We discussed with him an additional mobilization would be required to
proceed.
A second mobilization was made the week of June 17, 2019 to attempt to drill boring B-6 (boring
B-5, B-7 and B-8 had not yet been authorized by MDT). During the mobilization, the drill rig could
not access the location of boring B-6 as the boring location was surrounded by a raised earthen
berm the rig could not navigate.
A third mobilization was made the week of July 15, 2019 to complete the remaining borings (B-5
through B-8).The cost for two(2)additional borings(within the railroad right-of-way)beyond those
originally proposed is also being requested as a separate line item. Two additional borings located
within the MRL right-of-way, advanced to a depth of approximately 25 feet or practical auger
refusal, additional laboratory testing, MRL permitting requirements, and reporting time are
included in the breakdown of the additional two railroad borings. As requested by Sanderson
Stewart, COP Construction made a site visit with a CAT 335F excavator to excavate an entry path
to boring B-6 for the drill rig and excavate test pits near borings B-5, B-6, and B-8 so we could
observe and document cobble and/or boulder sizes within the gravel stratum. One day of traffic
control, provided by Mountain West, has also been included for the work along Montana
Department of Transportation right-of-way.
C. COMPENSATION
Based on information outlined above, we propose to complete the work on a time and materials
basis under the current project contract terms between HDR, Inc and Terracon. An estimate of
additional fees requested is provided below. The below estimate anticipates all borings can be
drilled out of traffic and as such, the fees below do not include time associated with traffic control.
The below costs also do not include any costs associated with acquiring permits to perform work
within the railroad or City right-of-way.
Item 1 —Additional mobilization to complete boring B-6 (June 17) Estimated
Fee
Mobilization for Terracon and Drill subcontractor to drill boring B-6. Drill $2 580
rig could not access the boring over the berm.
Total— Item 1 $2,580
