Avenue 44 Bridge at the Coachella Valley Storm Water Channel Project

The Project includes, without limitation, furnishing all necessary labor, materials, equipment and other incidental and appurtenant Work necessary to satisfactorily complete the Project, as more specifically described in the Contract Documents. This Work will be performed in strict conformance with the Contract Documents, permits from regulatory agencies with jurisdiction, and applicable regulations. The quantity of Work to be performed and materials to be furnished are approximations only, being given as a basis for the comparison of Bids. Actual quantities of Work to be performed may vary at the discretion of the City Engineer.The project is located along Avenue 44 between Palo Verde Street and Aztec Street in the City of Indio. The purpose of the project is to replace the existing low water crossing spanning the Coachella Valley Storm Water Channel (CVSWC) that was washed out from Tropical Storm Hilary with a bridge crossing. The proposed work includes the roadway approach reconstruction to meet the proposed structure elevation; roadway demolition, street widening; construction of curb, curb/gutter, sidewalk, driveway approaches, concrete slope protection with access ramps, concrete grade control structure, channel grading and hydroseeding, asphalt concrete with aggregate base, slurry seal, bridge lighting, chain link fence, gates, new storm drain pipes with outlets into the CVSWC, catch basins, drywells, water pollution control, signing, and striping.The Avenue 44 low water crossing is currently closed to traffic due to the damage from Tropical Storm Hilary. During construction, traffic will be detoured around the crossing so the bridge can be built in one stage.The proposed bridge structure is a haunched cast in place concrete box girder bridge with three spans. The piers consist of two 9ft diameter columns with 10ft diameter Cast-in-drilled-hole (CIDH) piles. The bridge is set on seat type abutments with 3ft diameter CIDH pile footings. Bridge barriers include architectural treatments along with architectural bridge lighting. The construction also includes relocating the water lines into the bridge as well as other appurtenant utility work necessary to accommodate a gas line and telecommunication through the bridge.Expect difficult pile installation at both abutments and both pier locations due to presence of groundwater, caving soil, buried utilities, buried concrete lining, rock cobbles, and large concrete debris.
