Woodward Island Bridge

County of San Joaquin, Department of Public Works – Woodward Island Bridge Project, (Subcontractor to The Dutra Group)

The project, located on the Middle River 12 miles west of Stockton, replaced the cable ferry with a new 675-foot bridge to provide uninterrupted vehicle access to Woodward Island from West Bacon Island Road. The seven-span bridge allows unlimited vertical clearance when the removable span is removed and 30 feet of vertical clearance when the span is in place.

The bridge was designed for a minimum design speed of 15 miles per hour and maximum grades of 8.5%. To accommodate the west abutment of the bridge and to provide adequate area for trucks exiting and entering the bridge, the Woodward Island levee road was locally widened by 20 feet and raised by 5 feet at the end of the bridge.

The bridge project was funded through the Highway Bridge Program. The Dutra Group constructed the piles and columns and installed the pre-cast girders. We constructed the abutments, bent caps and deck.

SR 1 Bridge Replacement in Olema

Hwy 1 Bridge Construction to Replace Culverts, Caltrans #04-4S7804

This project, in Olema, CA, consists of replacing existing culverts with a 36’ reinforced concrete slab bridge. The work is in a highly sensitive environmental area which makes the available staging area very constricted. The work will be done in 70 working days and consists of a temporary signal for traffic control, CIDH piling, soil nails, shotcrete, roadway excavation, bridge construction and ST-70 rail construction.

SR 99 Slope Paving, Gore Paving and MVPs

Stockton Gore and Slope Paving, Caltrans Contract #10-0X6404

This project consisted of 14 gore paving locations, 12 slope paving locations, and 6 maintenance vehicle pullouts along Highway 99 from Stockton to Lodi. The gore paving areas were treated with a brick stamp pattern and a red color hardener to provide a greater aesthetic appeal. We partnered with Caltrans to change the staging on the MVP’s to provide a more efficient process and reduce the impact to the travelling public. The slope paving operation was the most challenging aspect of the project. Access was limited due to the proximity of the freeway and the steep slopes made any use of equipment nearly impossible. Our team members worked together to create a plan to perform the work safely and executed each aspect to near perfection.

Trail: Guadalupe River/Coleman Road Under-crossing

6327-Trail: Guadalupe River/Coleman Road Under-Crossing, City of San Jose

This project consisted of new construction of a pedestrian trail over 500’ long, including two Structural Concrete Retaining Walls, Structural Concrete Wetland Wall on Reinforced Concrete Pile, over 500 cubic yards of import material, Asphalt Concrete pedestrian trail pavement, bicycle lane striping, and architectural hand railing. Partnering was a large part of the success of the project, including several retaining wall alignment redesigns on-the-spot, to avoid existing utilities, and revise the overlook, for a better final product for the public.

Harbin Springs at Harbin Creek Bridge Replacement Project

Harbin Springs Road at Harbin Creek Bridge Replacement Project, Lake County, Federal Project No. BRLO-5914 (106)

The Harbin Springs Rd. Bridge Replacement consisted of a 100’ long, temporary steel bridge to detour traffic, while the existing bridge was demolished and the new bridge was constructed back in the same place. The 100’ long steel bridge required the assistance of a 265 Ton Crane for hoisting, due to the limited access and nearby overhead power lines. The presence of Harbin Creek also brought environmental aspects to the project including the necessary installation of a stream diversion through construction and constant biological monitoring for protected species. The project already had short work windows due to the environmental permits for working within Harbin Creek, but the project became increasingly difficult due to a 6-week delay caused by the presence of an environmentally protected frog species. We partnered with the County to accelerate the contract to ensure the work could be completed in one season within the specified work windows in the contract. We increased our manpower and worked long hours to meet the schedule demands and provide a successful project for the County.

Pinole Creek Fish Passage Project

Canal Levee Elimination and Flood Protection Project, Segments 3 and 4, Contra Costa Water District, Contract #2016-PW-01

(Subcontractor to Garney Construction)

The Pinole Creek Fish Passage construction, which was administered by the Contra Costa Resource Conservation District was located at the Pinole Creek Culvert at I-80 (City of Pinole, CA) on property owned by the California Department of Transportation, Contra Costa County Flood Control and Water Conservation District, the City of Pinole, and on private property.

The Contra Costa Canal Replacement Project is a drinking water supply protection and flood management project to replace four miles of unlined Contra Costa Canal with reinforced concrete pipeline from the Discharger’s Pumping Plant 1 (PP1) to the Rock Slough Headworks. The first phase was completed in 2009 and replaced approximately 1,900 feet of unlined Canal
from PP1 to Marsh Creek (Segment 1). The second phase was completed in 2015 and included
the installation of approximately 5,500 feet of pipeline replacing the unlined Canal from Marsh
Creek to Sellars Avenue and 200 feet of pipe installed at the end of Contra Costa Canal near
Rock Slough that supports a Flood Isolation Structure (Segment 2).

This contract provides coverage for the current phase of construction (Segments 3 and 4) that will be constructed in 2018 – 2019 and Includes replacement of approximately 5,500’ of unlined canal from Sellers Avenue to a location about 1,000’ upstream (west) of Jersey Island Road and East Cypress Road with a 10-foot diameter pipeline.

Our portion of the project consists of constructing an Access Structure and Culvert Transition Structure in Oakley, CA. The first order of work will be to construct the Access Structure starting in June, 2018. The construction of the Access Structure will take careful planning with Garney Construction to tie-in the 10-foot diameter Ameron pipe. The Access Structure is a 26’ tall box that will require engineered form drawings in order to ensure that the forms are supported during the pour for the walls.

The roof of the Access Structure is to be constructed separately from the walls and requires the installation of long lead items that will need to be ordered in preparation of the concrete pour. Once the roof is constructed, it will set onto the structure and tied in. The Culvert Transition Structure will allow for the continuation of Little Dutch Slough over the installation of the 10-foot pipe. Prior to the installation of the culvert, Garney Construction will install dewatering wells and then install the 10’ RCP along with a sheet pile shoring system. After installation and backfill is complete, we will construct the Culvert Transition Structures on either end of the slough.

The Project entailed the construction of fish passage improvements on the existing culvert of Pinole Creek at I-80 Milepost 8.4 by building a concrete notch with baffles in the culvert, training walls on the culvert aprons, a terminal rock pool, and a rocked chute in the downstream channel. In order to gain access to the work, a creek diversion was necessary using a coffer dam and dewatering. The work was constructed under the direction of biologists and engineers to ensure the maximum benefit to fish and other biological resources.

Huff-Jelly Belly

Huff-Jelly Belly Warehouse, Aloyse Rowland, LLC, (Subcontractor to Bay Cities Paving and Grading), BCPG Job #3898

The design for the Jelly Belly Warehouse called for a portion of the parking lot to be pervious concrete instead of HMA. The project required the use of specialized rollers to provide a smooth finish and to cut the joints. We completed the project in 2 days and approximately 150 cubic yards of concrete was placed. The first day we poured the concrete for the parking stalls and then placed the concrete for the center on the second day. At the end of each shift, the concrete had to be covered with plastic for seven days in order for the concrete to cure correctly.

SR 680 at Bernal Avenue Retaining Wall

I-680 Ramp Metering and Traffic Operating Systems, Caltrans #04-4G1154, (Subcontractor to Bay Cities Paving and Grading, Inc.)

Essentially an add-on to the larger I-680 project, we will once again be a subcontractor to Bay Cities to construct 1,000 cubic yards of retaining walls including over 400 driven pile. Construction access will once again be minimal, but, with our ingenuity and experience, it will not be anything too large to overcome. This project will fit in perfect with the rest of the work being performed on I-680 and we will be a major contributor to the success of these construction projects.

SR 1 Pedestrian Bridge Replacement

Hwy 1 Replace Pedestrian Bridge, Caltrans #04-4G8504

This project, in Pacifica, CA, consists of replacing a pedestrian bridge over Hwy 1 at San Jose Avenue. The existing bridge was originally constructed in 1968 and had an earthquake retrofit in 1994. The bridge has 5 spans and is comprised of cast-in-drilled-hole piling, isolation casing, bridge footings, columns, cast-in-place concrete box structure, concrete bridge slab, intricate concrete surface texture and paint, and specialized fence.

Additional improvements are comprised of landscaping, pedestrian lighting, drainage, signage, ADA ramps with minor concrete, paving and striping. The new bridge will comply with current vertical clearance requirements and the Americans with Disabilities Act.

Marsh Creek Road Bridge Replacement

Marsh Creek Road Bridge Replacement, Contra Costa County, Public Works Department, County Project No.: 0662-6R4079

The work generally consists of removal of the existing bridge, construction of a new bridge (in 2 Stages), construction of the roadway section approaching to bridge, two retaining walls, reconstructing driveways, and installation of a new waterline. Our approach to the work was to complete both stages of construction in one season. While there were a significant number of stakeholders on the project who had significant influence, we were able to help the County with coordination, planning, and communication to ensure the project schedule was maintained.
