Kings County Bridge Preventive Maintenance Program
NCM was selected by the County to develop a Bridge Preventive Maintenance Program for the County’s inventory of 110 bridges, to clear and permit needed maintenance improvements under CEQA and NEPA and to develop PS&E for implementation of bridge preventive maintenance improvements. The program cost is estimated at more than $31 million.
Tulare County Bridge Preventive Maintenance Program
NCM is responsible for development of a Bridge Preventive Maintenance Program for the County’s inventory of more than 340 bridges using field review documentation compiled by the County. The plan will cover around 210 bridges with a total program cost of approximately $30 million.
Santa Margarita Parkway Bridge Hinge Repair
The purpose of this project is to environmentally clear and implement hinge repair and ancillary maintenance improvements for the westbound structure under the Federal Bridge Preventive Maintenance Program. The hinge will be removed and replaced to correct internal damage that has resulted in a vertical offset of 3/4″ to 1.5″, and a horizontal shift of 1/2″ to 3/4″ across the hinge and visible damage to the internal shear keys, bridge bearings, and longitudinal restrainers.
Standard Street Alternative Access Separation of Grade
Kern County initiated this project to improve circulation and safety for the Standard Street Industrial Area. The project will construct a secondary access route to the industrial area by extending Atlas Street from Atlas Court just west of Standard Street to a new intersection with Landco Drive, south of the existing Hageman Road / Knudsen Road intersection.
Monte Vista Avenue Grade Separation
NCM is responsible for development of final design and PS&E to grade separate Monte Vista Avenue in the City of Montclair from the UPRR main line and State Street. The project will construct a two span overhead structure to carry Monte Avenue over the railroad and State Street and improve safety by eliminating vehicle and train conflict. A spliced precast concrete girder structure is being utilized to avoid the use of falsework and minimize ground-level construction within the busy UPRR three track corridor.
Park Place Extension and Grade Separation
The project involves development of alternatives to extend Park Place from Allied Way to Nash Street and grade separate the new extension from the UPRR and BNSF spur lines that serve the Chevron oil refinery adjacent to the project site located in the City of El Segundo.
Union Patsaouras Plaza Busway Station Design-Build
The project is being delivered through the design-build process with a cost of $20 million and will reconfigure the Union/Patsaouras Plaza Busway station boarding island to improve bus operating efficiency and enhance pedestrian transit connectivity between Patsaouras Plaza and the El Monte Busway.
