Sewer lines were installed in very difficult circumstances, in conjunction with building shoring and up to depths of 30 feet.
Palisades Garden Walk
A crowded, congested small site in the heart of the Santa Monica required intensive planning and multiple backup plans in order to meet the schedule. On and offsite sewer and storm drain were the heart of the project, with multiple connections to existing utilities. The offsite sewer included depths of over 30 feet deep in the main drag of Santa Monica, Ocean Ave. One of the more challenging items of work involved installing an offsite water line across and down Ocean Ave and right in front of the iconic Santa Monica Pier.
Hilton Foundation Campus
On and off site utility systems for the beautiful and innovative new home of the Conrad N. Hilton Foundation. Blois work included storm drain, sewer, domestic water, reclaimed water and irrigation. As part of the of the building LEED certification, Blois helped design and install an innovative "grey water" recovery system to be used for irrigation. 3D BIM modeling drawings and coordination were also part of our scope of work.
Big Blue Bus Expansion
An innovative storm water retention and filtration system were the highlights on this project to expand the City of Santa Monica's public bus yard. The desire to keep all storm water runoff onsite required large underground retention vaults and filtration systems before discharging into the ground water. New sewer, water, firewater and gas were also installed for the new facilities. Pre-planning and coordination with the General Contractor was required due to phased construction intended to keep the existing facility in operation.
National Search Dog Training Center
Blois Construction installed all of the storm drain, sewer and leach fields and domestic and fire water for this project at a reduced cost to help contribute to the building of this important facility. The National Disaster Search Dog Foundation is a not for profit organization with the mission to train and provide search dogs to assist in the rescue of victims of natural disaster worldwide. One interesting aspect of this project was the combining of confined space training for our crews with the training for the search dogs, utilizing the new storm drain system that we installed.
Sony Main Street Improvements
Complete replacement of existing utilities in Sony Studios "Main Street" at their Culver City studios. Storm drain, sewer, domestic and fire water and steel gas line systems were installed in extremely tight conditions and scheduling restraints. The studios production schedule required Blois to work seven days a week and double shifts. In addition, work locations and access were constantly changed to meet the studio's needs. Unknown or mis-marked existing utilities resulted in "on-the-fly" design changes and made for challenging work.
Pumping Station No. 6b North
A project consisting of grading, canals, concrete structures, site piping, pumps and a control building to increase the Kern County Water Agency's flexibility in delivering water to its customers in the Central Valley. 250, 350 and 600 HP motors were installed in a concrete pump station designed for efficient water flow. Large steel and RCP pipe was installed between flow control structures with hydraulic slide gates controlling the flow. Coffer dams were used to control existing flows and make connections between new and existing canals under tight deadlines. A control building was built to house the SCADA system used to...
Port Hueneme Water Agency Discharge Station
Pump station, piping and other facilities to discharge water treatment by products into the Calleguas Salinity Management Pipeline. The work included mechanical piping, valves, concrete vaults & wet wells, meters, chemical feed equipment & piping and chemical tanks. The most challenging aspect of the work was the excavation, shoring and construction of a cast in place wet well below the existing ground water table in very limited space.
Sewer Brine Line Phase 1-B
Part of a project to increase group water supplies by over 40,000 acre-feet a year for the Calleguas Municipal Water District. Over 8,500 lf of 48" pipeline was installed in this segment to carry excess brine from the treatment process to the ocean. Due to the corrosive properties of the brine, never before used materials were incorporated into this project, including 48" C900 PVC fittings and required close coordination with the Owner and the Engineer. Other challenges included a 54" mirco-tunnel under an existing channel and extensive traffic control on a busy major road.
CLWA 118B Groundwater Restoration Project
Installation of over 20,000 lf of welded steel pipe, varying for 10" to 42" in diameter in existing city streets, city bike paths and on 3 existing bridges crossing waterways. Construction easements on bike paths were very limited and had very tight and strict schedule milestone that had to be met to accommodate City events. Heavy traveled and high traffic streets required that 50% of the street work to be installed at night. Existing utilities required installation of the 42" steel pipe at depths of 20 to 25 feet deep in the busy intersections. Environmental and biological monitoring was required...
Santa Monica Low Flow Diversion Upgrades Package 3
A very challenging job located in high risk and highly visible location.

Arundell Barranca Improvments
Over 3,550 lf of an exiting drainage channel was removed and replaced with a new 25 lf wide by 14 lf high concrete rectangular channel. Over 7,000 cubic yards of concrete, 850,000 lbs of steel and 100,000 cubic yards of excavation and removal were required to complete this project. Building the new channel required maintaining the flow in the existing channel while the new one was being constructed. Unexpected heavy rains in May caused extensive damage and required us to accelerate to complete the project before the winter rains hit.
24″ REW Pipeline from Mulholland Hwy to Tapia WRF
Installation of approximately 9,000 lf of 24" welded steel pipe line in a narrow, heavily traveled main thoroughfare between Calabasas and the Pacific Coast Highway. Heavy traffic required restricted working hours and careful planning. The discovery of Native American artifacts required a switch from open cut construction to bore and jack for a portion of the job. One of the most challenging aspects of the job was the presence of an existing utility line running parallel to the new line, requiring careful and innovative shoring.
Lincoln Place Apartments
Installation of complete sewer, water and storm drain systems for the construction of new apartments.
