Ice House Road at Jones Fork Silver Creek Bridge Maintenance Project

Ice House Road at Jones Fork Silver Creek Bridge Maintenance Project, El Dorado County, Federal Project No. BPMP-5925 (105)

The Ice House Road at Jones Fork Silver Creek Bridge Maintenance and Rehabilitation Project on Ice House Rd. in El Dorado County had many unique aspects that required significant engineering and attention to detail. The work included replacing aged bridge bearing pads, replacing Structural Concrete Approach Slabs, and replacing the Metal Beam Guardrail Systems. Challenges include a remote location with one entrance and exit location to access the project, requiring thorough pre-planning to complete the project. Other challenges faced while completing the project included hitting granite rock while drilling for the Guardrail Posts, requiring a redesign of the Guardrail to meet roadway specifications, while still being installed per manufacturer required specifications. The approach slab concrete was rapid setting concrete because the bridge had to stay open during construction. We had to jack up the bridge 1” and temporarily support the bridge during construction. Because of environmental requirements, no equipment could be used under the bridge which made all the work to be done manually.

18016 – Contra Costa Transportation Authority – Interstate 680 HOV Completion and Express Lanes Project (# 8001), (Subcontractor to Bay Cities Paving & Grading, Inc.)

This project provides construction of a high occupancy vehicle (HOV) lane on southbound I-680 between North Main Street in Walnut Creek and Rudgear Road in Alamo and converts the HOV lane to an express lane on southbound I-680 from just south of Marina Vista Avenue in Martinez to Rudgear Road in Walnut Creek. The structures work includes a bridge widening, retaining walls, barrier slabs, sound walls, pre-stressed concrete and CIDH pilings.

San Quentin Village Sidewalk and Retaining Wall Project

San Quentin Village Sidewalk Project, Marin County, Contract #2014-05

This project consisted of building a new five-foot sidewalk along the entire length of the south side of Main Street in San Quentin Village. The work included two soldier pile retaining walls, concrete curb, gutter, sidewalk, catch basins, ADA curb ramps, retaining curbs, driveway approaches, chain link fence, pedestrian handrail, pavement grinding, asphalt widening, utility relocations, clearing and grubbing, pavement striping, new road signs, and shoulder backing. Extensive traffic control measures were required to facilitate the work on this busy street providing access to the San Quentin Prison.

Sutter Creek

Badger Street Bridge Replacement, City of Sutter Creek, Federal Project No. BRLO 5215 (012)

The City of Sutter Creek’s Badger Street Bridge Replacement is located in the heart of the City of Sutter Creek in Amador County. The project consisted of replacing the Badger Street Bridge above Sutter Creek with a raised profile structure and improved roadway approaches.

Minor channelization in the streambed was necessary to improve hydraulic capacity. The modifications included construction of concrete wingwalls, relocating cut banks and removing remnant rubble and lowering exposed high spots in the stream bedrock. Rip rap was placed on exposed slopes to protect the creek banks from erosion.

In addition to the bridge construction, the project also required bridge demolition, paving, sidewalk/curb/gutter construction, landscaping, storm drain systems, sanitary sewer replacement and installation, and environmental impact mitigations.

Foard Road at Anderson Creek Bridge Replacement Project

Foard Road at Anderson Creek Bridge Replacement Project, Lake County, Federal Project No. BRLO-5914 (068)

The project on Foard Road required the bridge replacement on an existing alignment with approximately 350 feet of roadway reconstruction with paving over aggregate base. The project also included installation of a detour and temporary bridge. A temporary creek diversion and dewatering was required to build the bridge, along with utility relocations, temporary fills and metal beam guard rail work. The work, which took place during one of he wettest winters in recent history, was accelerated to ensure that we were able to complete the work in the creek by October 31st.
