This project, performed via Holdrege & Kull’s on-call contract with Nevada County, relocated/ replaced a former transit center to a new location on Tinloy Street between Bank and East Bennet Streets in Grass Valley. H&K worked closely with all agencies involved, including the City of Grass Valley, the California Department of Transportation, and the County of Nevada. The new center was designed to provide a safe and secure facility, while capitalizing on the visibility of the site and reflecting the unique architecture of Grass Valley. The project also required being cognizant of the environmental sensitivity of the adjacent Wolf Creek.
The project was built on approximately 1.4 acres and included a Concrete Masonry Unit (CMU) restroom/pump/storage building, 330-foot-long transit vehicle transfer bay, 12-foot-wide ADA compliant sidewalks/passenger waiting area, two shelters, retaining walls, passenger parking bays, and other related site elements.
H&K performed a geotechnical investigation and provided recommendations for the project. During construction, H&K provided testing and inspection services in accordance with Caltrans for such things as engineered fill, subgrade for roadways and sidewalks, minor concrete, and Hot Mix Asphalt for pavement sections. As construction moved into the vertical stage, H&K provided materials testing and inspection in accordance with the California Building Code for structural concrete, masonry, and steel.
