This is a Bidder's Checklist and Narrative Response document for the California Department of Parks and Recreation regarding the Mono Lake ADA Boardwalk Materials project (BU 3790, Event ID 0000039497). The project requires the contractor to provide materials for replacing the Mono Lake ADA boardwalk trail, consisting of 740 lineal feet of boardwalk with a 6-foot outside-to-outside width. The boardwalk materials must be composed of fiber reinforced polymer (FRP) composite materials manufactured using continuous ECR glass fiber and vinyl ester resin with non-woven polyester veil applied during manufacturing. The decking specification calls for 38mm mini-mesh decking with anti-slip surface in 4-foot by 6-foot by 1.5-inch thick panels, with bull rail edging attached flush to the outside of the decking. All structural spans must be engineered for 20-foot spacing between Diamond Pier foundations and rated for 100 psi live load to accommodate the sensitive wetland environment.

All boardwalk materials must be painted with a two-part fluoropolymer coating (such as Vitreflon or approved equivalent) in RAL 080-30-26 (Smoked Oak) color to comply with strict scenic corridor constraints and withstand the high alkaline and UV exposure environment. Hardware and brackets must be stainless steel and provided in full to connect all boardwalk materials directly to the concrete Diamond Pier foundation, which will be provided by Parks. Version 3 Addendum 1 included updates to key dates for the project. The bidder's response document serves as a checklist and narrative format for contractors to demonstrate compliance with all specified material requirements and project parameters.
