Award a construction contract to Rite -Way Roof Corporation for the replacement of the Santa Clarita Sports Center Gymnasium roof through Sourcewell Contract 062117-DAC in the amount of $446,259 and authorize a contingency in the amount of $66,939, for a total contract amount not to exceed $513,198. 2. Authorize the City Manager or designee to execute all contracts and associated documents, subject to City Attorney approval. BACKGROUND The Santa Clarita Sports Center Gymnasium Roof Replacement Project, Project P3031, will remove and replace the roofing material on the Santa Clarita Sports Center Gymnasium. The roof replacement is part of the City of Santa Clarita's (City) comprehensive maintenance plan for sustaining facilities Citywide and supports the Santa Clarita 2025 theme of Sustaining Public Infrastructure. The roof material is deteriorating at an accelerated rate, due to its age, and multiple leaks are occurring throughout the building. Staff has attempted to patch and repair the roof, however, several leaks recur each year due to roof membrane slippage. Based on the condition of the roof, patch work is no longer an effective repair method and replacement is now needed. This project will install a new roofing membrane on the entire building and provide a 20-year warranty on the material. Completing this roofing replacement will prevent further water -related damage and will ensure recreation programs are not adversely impacted. Page 1 Packet Pg. 134 On July 11, 1995, the City Council approved the use of "piggyback" purchasing. This process permits the City to place orders against a competitively -awarded, existing public agency contract. The Sourcewell Contract 062117-DAC was competitively solicited and awarded on August 17, 2017, and is valid through 2021. Staff recommends awarding the contract to Rite -Way Roof Corporation, which is contracted with the Sourcewell Cooperative purchasing agreement, in the amount of $446,259 and authorize a contingency in the amount of $66,939, for a total contract amount not to exceed $513,198. The requested contingency will cover hidden conditions, such as the replacement of plywood and framing members damaged by years of water leaks. ALTERNATIVE ACTION Other action as determined by the City Council. FISCAL IMPACT Adequate funds are available in expenditure account P3031601-5161.001 (General Fund - Capital) to support the recommended construction contract and construction support costs.
