Bridgestone/Firestone – Lakewood, CO Addendum June 21, 2012
PSI Project No. 532281 Page 6 of 6
Some increase in moisture content is inevitable as a result of development and associated
landscaping. However, extreme moisture content increases can be largely controlled by
proper and responsible site drainage, building maintenance and irrigation practices.
Utility backfill in areas supporting slabs should be moisture conditioned or dried by
scarification, and compacted. Backfill in interior and exterior water and sewer line trenches
should be uniformly compacted.
Exterior slabs should be isolated from the building. These slabs should be reinforced to
function as independent units. Movement of these slabs should not be transmitted to the
building foundations or superstructures.
PSI appreciates the opportunity to submit this addendum and look forward to working with you
on this project. If you have any questions concerning our report, please contact our office.
