Title
Staff Report for a Resolution Accepting the Work for the Sanitary Sewer Line Replacement/Repair 2012-13 Project, Project No. 2013.0120
Staffreport
SUMMARY AND RECOMMENDATIONS
Staff recommends that the City Council accept the work by Con-Quest Contractors, Inc. for the Sanitary Sewer Line Replacement/Repair 2012-13 Project and authorize the City Manager to file the Notice of Completion, release the performance and payment bonds, and release the maintenance bond upon successful completion of the one-year maintenance period.
BACKGROUND
The subject project replaced approximately 2,200 linear feet of pipe of various sizes, built or reconstructed 26 manholes, along with other miscellaneous repair items as identified on the project plans. These improvements increased the sanitary sewer system’s reliability, reduced the frequency of required maintenance, reduced the risk of sewage overflows and improved system access and efficiency of maintenance operations.
Composite non-metallic manhole frames and covers were installed on a trial basis at several locations where sewer gases have corroded the existing metal frames and covers; the performance of these items will be monitored. The non-metallic manhole frames and covers are lighter than their metal counterparts, are unattractive to metal thieves, and are corrosion resistant. The composite covers have locks operable only with special tools to deter unauthorized access.
Analysis
On April 20, 2015 the City Council awarded the construction contract for the subject project to Con-Quest Contractors, Inc. Construction is complete. The work was inspected and deemed to comply with the contract documents and City standards.
To address major emergencies encountered during this project, staff requested and obtained City Council approval to increase the contract amount. Two urgent situations were resolved with this expanded contract: upsizing the deteriorated sewer main on West Juana Avenue, which serves the 200-unit Marea Alta housing development, and repairing a broken sanitary sewer force main line at the intersection of Merced Street and Fairway Drive. The sewer force main was likely damaged during the construction of a PG&E project in 2015. The City submitted a claim to PG&E for the cost of repairs by Con-Quest Contractors and the cost of City staff time associated with the force main repair and clean-up efforts.
