Subject to conditions prescribed by the University of California, Davis, responses to the University's prequalification documents for a Lump Sum contract are sought from prospective bidders for the following project: Arboretum Waterway Enhancement Project, Project No:9539500, GrantNumber UF8825-0. PREQUALIFICATION OF PROSPECTIVE BIDDERS The University has determined that bidders who submit bids on this project must be prequalified. Prequalified bidders will be required to have the following California contractor's license: General Engineering "A" GENERAL DESCRIPTION OF WORK The Arboretum Waterway is an east-west flowing section of the historic channel of Putah Creek, located on the UC Davis central campus and part of the campus stormwater system. The waterway is no longer naturally connected to a live stream. An improvement project, known as 'Phase 1', was completed in 2018 at the east end of the waterway. Phase 1 included sediment removal, a recirculating pump, and constructed weirs designed to manage water surface elevation and flow. The Arboretum Waterway Enhancement Project will continue improvements from the end of Phase 1 to the west end terminus of the channel, where water is pumped out of the waterway into Putah Creek. The Arboretum Waterway is not a Corps regulated Water of the U.S. Work in the waterway does require state Lake and Streambed Alteration Agreements, which the University is procuring. Work will include dewatering the waterway in segments, managing water input from stormwater drainage outfalls into the waterway during construction, demolition of gunnite and gabions along waterway banks, and re-grading within the channel. Grading will include recontouring and reshaping portions of the channel to create new topography for wetland and riparian planting areas, burying sediment and removed gunnite underneath the waterway. Three concrete retaining/grade control weir structures with adjustable outfalls will be constructed in the waterway. Two recirculating pumps, intakes, and outflows along with underground supply lines will be installed. Erosion control and compliance with all SWPPP, CEQA, any other regulatory requirements will be required. Contractor will manage preservation and selective pruning of existing trees and other vegetation during demolition/site preparation. Once engineering work is completed, Arboretum staff will manage revegetation of newly-constructed channel banks and islands. Some adjacent portions of the Arboretum will remain open to the public during construction.
