Design-Build P1046B Reclaimed Water Conveyance Pipelines at Camp
Pendleton, CA
This design-build project, valued at $21,628,498, was for the construction of 64,000LF of HDPE reclaimed water conveyance pipelines. 高倍德州扑克 as the design-builder, teamed with GHD as its designer of record for this project. The project included the construction of two pump stations, three storage reservoirs, six trenchless installations totaling 8,800 LF, new irrigation systems, road rehab, and work in culturally and environmentally sensitive areas. 高倍德州扑克/GHD identified design and construction methods to reduce impacts, complying with strict regulatory requirements. 高倍德州扑克 identified early in the design process ecologically sensitive areas including vernal pools, salt marshes, riparian, and coastal sage, with numerous endangered species such as the arroyo toad, loggerhead shrikes, least bell’s vireo, clapper rails, yellow-breasted chat. 高倍德州扑克/GHD then developed design and construction plans to mitigate impacts, utilizing trenchless construction, including Horizontal Direction Drills. These were also used to install the new pipeline beneath three rivers as the method of choice for Army Corps approval, and an archaeologically important site. 高倍德州扑克 restored disturbed areas in strict compliance with the revegetation plans developed in design and certified them at the one-year final inspection to the jurisdictional regulatory agencies that the required restoration success rates had been achieved.
V-1 W Vista Way Sewer Phase 1 in Vista, CA
高倍德州扑克 was the prime contractor on this $6,491,625 city project and the project intent was to upgrade the existing sewer system due to capacity deficiencies through their trunk main using open cut and micro tunneling installation methods. 高倍德州扑克 installed 3096 LF of new sewer trunk main between 12” to 15”, and 22 new manholes, located and reconnected 16 existing sewer laterals, and excavated and shored the launching and receiving pits for micro tunneling. The project proved challenging due to the trench depths in narrow City streets, which varied between 12’-25’ deep during open-cut installations. Micro tunneling pits were excavated and shored to depths of 35’ with beam and plate. A total of 685 LF of 42” diameter steel casing was installed using micro tunneling with a 15” PVC pipe installed inside the casing.
