FALCON Engineering Services (FALCON) provided construction management and inspection services for the County of Riverside on an on-call basis for bridges, roadways, and roadway-related facilities. The work included construction management services, source inspection services by Greenbook, Caltrans Standards and Manuals, LAPM, and projects specific quality management plans. The project personnel provided detailed diaries with inspections performed, relevant conversations, a situation encountered, time spent on each work order, etc., and maintained a photo log for each project.
SR-79 Widening: FALCON provided Construction Inspection for the SR-79 Widening project to relieve congestion, improve safety, and provide consistency with other improvements along SR-79.

Clinton Keith Extension, RCTD: FALCON provided Construction Management support services, plan review, and bidability. The improvements include approx. 2 miles of new roadway from Whitewater Road to Leon Road, the construction of a new bridge over Warm Water Creek, new wildlife overcrossing bridge, and a retaining wall system east of Warm Spring Creek. The project included the installation of a new traffic signal at the intersections, modification of existing traffic signals, drainage improvements, curb and gutter, driveways, sidewalk, bus pads, curb ramps, concrete barrier, roadside signs, fence, thermoplastic markings, and striping. FALCON Team and Structures Representative performed a thorough Constructability Review and made specific recommendations to the County. This resulted in revising minor staging, quantity bid items, and re-evaluating the soil report recommendations concerning the roadway excavation to include pavement for soft/rock excavation by identifying the rock level and determining hard rock types vs. decomposed granite. During the early stages of bridge construction and CIDH piling operation, FALCON encountered higher rock formation than what was shown on the boreholes’ logs. FALCON Structures Representatives immediately communicated this issue with the County and designer, and the geotechnical engineer was able to have the designer re-evaluate the CIDH pile depth at both abutments and bents, thus eliminating the significant potential delay and a considerable cost for idle equipment saving the County potential ~$10,000/day claims.
