Addendum 1 to Original Report
Proposed Bridgestone/Firestone
NWC of Vance Street and West Center Avenue
Lakewood, Colorado
PSI Project No. 0532281
Dear Mr. Dever:
In response to the recent discussions with Mays & Company, we are pleased to transmit this
addendum to PSI’s original geotechnical investigation. This addendum includes
recommendations to aide in design of the proposed Bridgestone/Firestone in Lakewood,
Colorado.
Project Information
PSI understands that Bridgestone/Firestone is planning the construction of a new retail facility at
the northwest corner of Vance Street and West Center Avenue in Lakewood, Colorado.
Original Report
PSI performed a geotechnical investigation for the proposed development and issued a report
entitled, “Report of Geotechnical Engineering Evaluation, Proposed Bridgestone/Firestone,
NWC of Vance Street and West Center Avenue, Lakewood, Colorado,” PSI Project No.
0532281, dated April 20, 2011 .
Additional Information
Subsequent to issuance of the above referenced report, PSI has had phone conversations with
Ms. Michelle Smith and others with Mays & Company. Briefly, PSI understands that due to cost
considerations, alternative recommendations are requested to include overexcavation and
recompaction with imported soils, and a shallow foundation system.
Alternative Foundation Design
Based on the subsurface conditions observed and our experience with similar materials, it is PSI’s
opinion that the on-site overburden soils and bedrock can generally be characterized as having
“moderate” to “high” swell potential and the proposed development should be designed to
accommodate for swell potential.
