DESCRIPTION: At its meeting of March 20, 2007 the City Council awarded a
contract to Sierra Bay Contractors Inc. for the Shannon Community Center. The new building is
approximately 19,000 square feet in size and is located within the area of the original Shannon
Community Center.
The project is now under construction and during the demolition of the existing building the contractor
uncovered approximately eighty concrete piers ranging in depth form ten to twenty feet. These piers were
not shown on any record documents available to the City and were required to be removed by the City's
Soils Engineer for structural reasons. The unanticipated excavation of the piers resulted in a condition
that now requires additional grading and excavation to properly prepare the soil for the foundation of the
building. Consequently a Change Order to the original contract is needed.
The contractor has given preliminary estimates for this work that are in excess of what is within the City
Manager's authority to approve. Staff is still in negotiation on some of the costs; however, as this item is
on the critical path of the project, Staff is seeking authorization for a change order in an amount not to
exceed $75,000 in order to keep the project on schedule.
RECOMMENDATION:
Resolution.
It is the recommendation of Staff that the City Council; Adopt the
