NWC of Vance St. & W. Center Ave. PSI Project No. 532281
Lakewood, Colorado Page 1 of 15
1.0 INTRODUCTION
Professional Service Industries, Inc. (PSI) has conducted a geotechnical engineering
evaluation for the proposed Bridgestone Automotive Store to be located at the northwest
corner of the intersection of Vance Street and West Center Avenue in Lakewood,
Colorado. The purpose of our study was to characterize the subsurface strata at the
subject site and to develop recommendations for site preparation and for foundation and
pavement design for the proposed Bridgestone development. Our services on this
project were authorized by Mr. Kenton Girard with Bridgestone Retail Operations, LLC
with the Geotechnical Engineering Agreement between PSI and Bridgestone Retail
Operations, LLC.
PSI’s scope of services for the geotechnical study did not include an assessment of
environmental conditions in the soil, bedrock, surface water, groundwater, or air, on or
below, or around this site. Any statements in this report or on the boring logs regarding
odors, colors, and unusual or suspicious items or conditions are strictly for informational
purposes. The report, which follows, presents a brief review of our understanding of the
project, a discussion of the site and subsurface conditions, and our recommendations.
2.0 PROJECT INFORMATION
PSI has been provided with project information for the proposed development from Ms.
Julie Emmett with Mays and Company. We understand that Bridgestone is planning the
construction of a Bridgestone/Firestone auto service store to be located at the northwest
corner of Vance Street and West Center Avenue in Lakewood, Colorado (See Figures 1
and 2).
The latitude and longitude of the subject site is approximately 39º 42’ 20” North and 105º
04’ 49” West. The subject site is bounded by an undeveloped parcel to the north, a
paved parking area to the west, West Center Avenue to the south, and Vance Street to
the east. The site proposed for development is currently undeveloped with a mixture of
weeds and grasses covering the site. The subject site is relatively flat with gentle slope
to the southeast.
Based on the information provided to PSI, we understand that the proposed
development will include the construction of an approximately 8,500 square foot singlestory
structure with no below grade structures. The Bridgestone building type planned is
L-2010 SEPT-10L according to the provided site plan.
PSI has not been provided with the expected loading for the building. Therefore, for the
purpose of this report, PSI expects that the proposed structure will not exceed column
loads of 30 kips, wall loads of 1 kip per linear foot, floor loads of 125 psf, and
concentrated lift loads up to 5 kip point loads.
A grading plan was not provided for this site; however, based on the existing site
topography, only minor filling/cutting is anticipated for the majority of the subject
property.
Descriptions of the site are based upon observations made during our field exploration
program. The geotechnical recommendations presented in this report are based upon
the available project information and the subsurface materials described in this report. If
