Set Public Hearing For_ CONTINUED TO FILE NUMBER CITY MA AGER RECOMMENDED ACTION Increase the contingency for the contract with Hillcrest Contracting Inc. for the construction of the Bristol-Warner Intersection Widening Project by $250,000 to a total estimated contract amount of $1,587,091 and authorize the City Manager to execute change orders in an amount not to exceed the authorized contingency. DISCUSSION On March 21, 2011, the City Council awarded a contract for the Bristol-Warner Intersection Widening Project to Hillcrest Contracting Inc. in the estimated amount of $1,215,538 plus a 10 percent contingency of $121,553 totaling $1,337,091. The project is 40 percent complete with 79 percent of the contingency exhausted. The major changes that expended the contingency are: the replacement of a 24-inch corroded storm drain pipe at a cost of $68,000, the relocation and resizing of a precast concrete vault at a cost of $24,231, and the relocation of two backflow devices at a cost of $3,680. Additionally, there are several major changes outstanding such as a bypass for a broken 16-inch water valve and the relocation of an existing Metropolitan Water District metering station at an estimated combined cost of $101,500. With the outstanding changes and the unforeseen conditions that are associated with construction of a street widening project and underground utility work, staff recommends increasing the contingency by $250,000.
