RECOMMENDATIONS:
That the City Council:
Award Bid No. 8127 to R&R Roofing and Waterproofing, Inc., of Lake Elsinore, California in the amount of $660,705 for the Re-roof of three (3) structures at the Riverside Municipal Airport, located at 6951 Flight Road; Authorize 15% change order authority in an amount up to $99,105.75 for a total not to exceed amount of $759,810.75 for project changes including, but not limited to, unforeseen conditions, or necessary design changes; and Authorize the City Manager, or his designee, to execute the Agreement for Construction with R&R Roofing and Waterproofing, Inc. including making minor and non-substantive changes.
BACKGROUND:
The roofing systems across three critical facilities at the Riverside Municipal Airport—the Main Terminal Building, Waypoint Aviation West, and Hangar E—have reached a state requiring immediate replacement. Built in 1968, the Main Terminal serves as a central hub for aviation schools, a local café, and a heavily trafficked lobby. A re-roof will preserve the structural integrity required for daily operations and public safety.
The Waypoint building and Hangar E have prolonged exposure to the elements and the aging nature of existing roofing materials have increased vulnerability to leaks, water damage, and structural inefficiency.
DISCUSSION:
On March 27, 2025, the Purchasing Division of the Finance Department issued RFB No. 8127 through the online bidding system, Planet Bids, seeking services from experienced construction firms to provide all labor, materials and equipment necessary to remove the existing roofing systems and dispose of in a legal manner and install the specified roofing system at three (3) buildings at the City of Riverside Airport in accordance with the bid specifications. The three buildings are the Main Terminal Building, the Waypoint Aviation West building and Hangar E. A total of 106 City of Riverside vendors and 500 external vendors were notified.
A mandatory pre-bid meeting was held on April 29, 2025, with twenty-four (24) vendors in attendance. RFB 8127 closed on May 20, 2025, with a total of twelve (12) responses. Two (2) bids were deemed non-responsive. R&R Roofing and Waterproofing, Inc. was deemed the lowest responsive bidder in the amount of $660,705.
