Recommendation
Staff recommends that Council:
1. Approve and authorize the City Manager or their designee to execute
Construction Contract Number C22182558 with Enterprise Roofing Service, Inc.
in the amount of $497,233 for the Cubberley Community Center H-Wing Re-Roof
Project, Capital Improvement Program Project CB-16002; and
2. Authorize the City Manager or their designee to negotiate and execute one or
more change orders to the construction contract with Enterprise Roofing
Service, Inc. for related, additional but unforeseen work which may develop

Background
The existing Cubberley Community Center H-Wing roof has been in service for 29 years and is
exhibiting signs of severe wear. The roof is leaking and has been patched several times in
various locations. To avoid the potential for larger leaks and structural damage to the building,
staff has determined that the roof needs a complete replacement.
Discussion
Project Description
This project will replace the existing H-wing roof with a new, energy efficient bituminous roof.
The existing tar-and-gravel roof is past the end of its useful life and needs to be replaced. The
application will meet current cool roofing codes to optimize energy efficiency. The roofing
manufacturer will provide a 20 year, no dollar limit warranty.

Number of Bids Received: 7
Bid Price Range $396,500 – $ 585,500
Staff reviewed the seven bids, and all were deemed responsive. Bids ranged from a low bid of
$396,500 to a high bid of $585,500 for the project. The lowest bidder asked to withdraw their
bid in accordance with the Public Contract Code, due to an error in pricing. The request to
withdraw was reviewed, found to comply with statutory requirements, and was thus approved.
Staff recommends that the bid of $497,233 submitted by Enterprise Roofing Service, Inc. be
accepted and that Enterprise Roofing Service, Inc. be declared the lowest responsible bidder.
The low bid is 16.7 percent below the engineer's estimate of $596,736. The change order
amount of $49,723 (which equals 10 percent of the total contract) is requested for related,
additional but unforeseen work which may develop during the project. Staff confirmed with the
Contractor's State License Board that the contractor has an active license on file. Staff also
contacted the listed references for Enterprise Roofing Service, Inc. and found that they have
performed satisfactorily on past construction projects for other clients.
