Proposed Action.
Staff recommends adoption of the following motion: Move that Council
authorize Change Order No. 4 as it concerns the 7th Street S. Landfill
Gas Remediation, Project 90 -18.
Overview.
Once trenching, barrier installation, and backfill operations had
proceeded beyond the five Westbrooke Patio Townhomes, it was
determined that some landfill debris had been left in place,
especially near buildings 2 and 4. Borings were taken to ascertain
quantity and range of the debris, and' plans were developed for the
removal of the remaining landfill waste. This required careful
excavation and a technique of digging that included waste of
previously placed backfill. The contractor agreed to perform the work
at bid unit prices.
