Our principal served as the Construction Manager (under Parsons’ contract) who led and directed the construction management team in the performance of construction engineering and inspection services, including survey and materials testing. He was responsible for developing all construction management, safety, quality, and project control procedures. The scope of work included constructability review, bid process assistance, contract administration, CPM schedule analysis, shop drawing review and approval, falsework review, construction inspection, survey checking, materials testing, storm water pollution prevention plan (SWPPP) compliance, environmental compliance and permits, addressing RFIs, and dispute resolution. Project documentation was maintained in Microsoft SharePoint, including two live video feeds documenting daily construction progress, for easy, online access by client and project staff. The project completed five months ahead of schedule. The project consisted of constructing a new railroad underpass structure to accommodate two existing BNSF Railway tracks with room for the future third track; two shoofly tracks approximately 3,060ft each; realign and widen Ranchero Road to a four lane roadway from Seventh Avenue to Danbury Road for approximately 7,940ft; installation of major storm drainage systems, including a five cell reinforce concrete box (RCB) culvert across Antelope Valley Wash; and relocation of existing dry and wet utilities, including waterlines and access man-way. The underpass structure is a new rolled wide flange steel beam bridge with a concrete deck. The new four span bridge is approximately 213 ft in length and consists of two 72 ft interior spans with eighteen W40x327 beams over the roadway, and two 34 ft approach spans with 18 W33x170 beams over the cut slopes. The superstructure consists of a 9” concrete deck.
