Walter, Director of Public Works -7DW Prepared By: Michael J. McGuire, Engineer III SUBJECT: CITY HALL ROOF REPAIRS, SPECIFICATION No. 90778 RECOMMENDATIONS I. Approve plans and specifications for "City Hall Roof Repairs, Specification No. 90778". 2. Authorize staff to advertise for bids. - 3. Authorize the City Manager to award a construction contract if the lowest responsible bid is less than the Engineer's Estimate of$250,000. 4. Approve a transfer of$50,000 from the project construction account to the project construction management account. DISCUSSION Background Over the past several years, there have been numerous water leaks in City Hall that have caused damage to various wall and ceiling areas. After the San Simeon earthquake in December 2003, the water leaks became more pronounced and frequent. To assist in determining the best approach to address the problems, staff hired a roofing consultant, Architectural Roof Design Group (ARDG), to investigate and report their findings. The Roof Leak Analysis Report, prepared by ARDG, revealed that the current roofing system is inadequate to provide correct protection for the building and discovered some problems with the roofing components, which resulted in the advanced deterioration of the roof and subsequent water intrusion into the City Hall building. Staff determined from this report that the roof would require complete replacement. ARDG was retained as design consultant for roof repairs to City Hall and have prepared plans and specifications that include the removal of the existing clay the roofing, placement of new membranes and coatings for proper sealing of the roof deck and mechanical equipment and a more secure hold-down for the clay tiles. CONCURRENCES This project has been determined to be Categorically Exempt under the California Environmental Quality Act(CEQA)by the Community Development Department. FISCAL IMPACT The 2007-09 Financial Plan, Appendix B, pages 3-528 to 3-532, originally identified $360,000 for construction and $20,000 for construction management for this repair project. Currently, there is only $360,000 available in the construction account. When this project was starting the 0---:� - I City Hall Roof Repairs—Spec No. 90778 Page 2 design phase with ARDG in 2009, the funds in the construction management account were transferred into the design account to fully fund design consultant fees. As part of departmental budget reduction measures, it was intended that inspection for the project would be done by in- house staff. It is anticipated there will be a large and demanding workload for the Public Works Inspection Division this summer, such that consultant construction management services will be needed to provide sufficient construction inspection for this project. Staff is recommending that $50,000 be transferred from the construction account into the construction management account to fully fund construction management and inspection services. Due to the ongoing favorable bid climate, staff believes that the remaining funding of$310,000 in the construction phase will be adequate to fund the construction contract.

The City Council could choose to deny the approval for advertising. Staff does not recommend this alternative. Should the approval to advertise be denied or deferred, roof repairs for City Hall will be delayed and subject to additional water leakage into the building during the rainy season, resulting in water damage to the building's contents, lost work productivity of the staff and continued use of maintenance staff for repair and cleanup.
