Sukut was awarded a $28.7 million Wastewater Reclamation Project, located in Yucca Valley, CA. The project is adjacent next to the existing Hi-Desert Water District project, also executed by Sukut. The scope consists of constructing over 32 miles of gravity sewer pipeline and 422 polymer manholes. The pipes will range in size from 6” to 21”, and vary in depth from 6’ to 25’. Construction of the system will include 4 jack and bore crossings through Caltrans Right of Way at Highway 62, and 1 jack and bore crossing across San Bernardino County Flood Control of Way.
The Lake Isabella Dam Safety Modification Project (DSMP) consists of several major modifications which will enhance the structural capability of the existing dam and will serve to increase public safety as well as restore the water storage capacity in Lake Isabella. Improvements to the Isabella Dam have been contemplated for many years – The original Dam was completed in 1953, although since 2006 there have been concerns about seismic stability.
Los Olivos Basin project involves the construction of multiple improvements for the Natural Treatment System (NTS) basin, including water inlet and outlet control structures, rip rap armoring for the basin, flow control gate and stop logs, basin access ramp, access stairways, perimeter fencing, water quality sampling stations, landscaping, irrigation, and electrical service. Work is cheduled to be completed by January of 2018.
Sukut completed emergency repair of the storm drain inlet and road crossing across the main landfill access road. Work included demolition of existing drainage features, construction of 3 concrete inlet structures, installation of 200 LF of 60” CHDPE Storm Drain and AC Paving. Project required a significant amount of coordination with the landfill operations and traffic control due to working on the main landfill access road.
Sukut completed a 5.8-acre cell construction, consisting of a five layer liner systems (two 2’ clay layers, 1’ LCRS gravel, 1’ sand, 2’ one-inch minus material). Project highlights include:
· 28,000 CYs of imported and placed clay soil.
· 7,000 CYs of LCRS gravel placed, along with 7,000 CYs of sand placed and imported.
· Installed 1,300 LF of LCRS HDPE pipe.
· 250,000 SF of liner installation on both slopes and floor.
Sukut was listed as the apparent low bidder on the Moffett and Legacy Roadway Extension project located in Tustin, CA. The project involves grading, installation of approximately 3,000 lf of new storm drain, new roadway, traffic signals, and over 10,000 lf of wet and dry utility construction
The land where the storm drain project was located was being leased by a nursery. Existing irrigation pipes had to be kept in service at all times therefore daily coordination with the nursery operation was necessary to mitigate problems.
The following is a brief description of work completed:
• Construction of approximately 2,000 lineal feet of 120 foot diameter storm drain pipe,
• 1,300 lineal feet of double reinforced concrete box culvert,
• 5,000 lineal feet of sewer (15-35 feet depth), and associated road improvements including paving and v-ditch.
Sukut mobilized its fleet of dozers and scrapers, including the new CAT D11T dozer, to move more than 1.1 million cubic yards of dirt and rip nearly 70,000 tons of rock. Sukut installed portions of the 4,700’ long storm drain at depths greater than 30 feet. In addition, Sukut constructed numerous structures including a 3’ x 6’ reinforced concrete box that, upon completion of the Bake Parkway bridge project, will flow into the San Diego Creek.
