Title
Staff Report for a Resolution to Authorize a Change Order and to Accept the Work for the Water Pollution Control Plant Dirt Removal 2017, Project No. 2015.0300
Staffreport
SUMMARY AND RECOMMENDATIONS
This project was modified to provide testing of a portion of the soil generated by the Water Pollution Control Plant (WPCP) Rehabilitation project.
Staff recommends authorizing a change order to modify the scope of work and accepting the soil testing work done by Pacific States Environmental Contractors, Inc. (Contractor), releasing the bonds for the work, and filing the notice of completion.
BACKGROUND
The Water Pollution Control Plant (WPCP) rehabilitation project generated a large volume of soil, most of which was off hauled as part of the original construction project. Approximately 40,000 tons of the dirt generated was found to have higher than expected levels of metal and other contaminants and was stockpiled on site for possible treatment, re-use, or off haul.
The subject dirt was stockpiled on site because the cost of treatment, re-use, and/or off haul was deemed to be significant enough to warrant competitive bidding of the work.
This contract was originally for removal of approximately half the dirt stockpiled on site; however, the contract was modified significantly as described below.
Analysis
Staff halted work on the contract upon receipt of additional test results indicating that the dirt was too contaminated to be hauled as specified in the bid and as identified in the original testing. Staff requests authorization to issue a change order for negative $719,735 (-98.6%) to cancel the dirt hauling work and compensate the Contractor only for its costs to move equipment in and out, collect dirt samples, and run laboratory tests on the dirt.
Since no construction work will be completed Staff recommends that the bond described in the contract for security during the one-year maintenance period should be waived.
Staff is evaluating the most economical alternative for disposal of this dirt, and a separate bid for the work will be conducted if or when a solution is chosen.
