Consultant completes Carlsbad power supply support design

Engineering consultancy, NV5 Holdings, has completed the design and construction of support services for the power supply to the Poseidon desalination plant in Carlsbad, California.

“NV5’s use of cutting-edge technology, such as a 3D high definition scanner and advanced 3D modeling software, along with unique and creative design approaches, were key to the successful completion of this project,” said power group director at NV5, Doug Taft.

NV5 worked with a southern California utility company on underground trenching, structural designs to support above-ground conduits, and a special above-ground vault system design that enabled four 12kV distribution circuits to feed the plant.

The consultant took a novel approach to support fibreglass conduits using steel supports in the abandoned Encina storage facility pit.

The Poseidon desalination plant project won three major plaudits in recent weeks, including an award from the American Public Works Association (APWA), the 2014 Outstanding Energy Project Award from the American Society of Civil Engineers, and a 2014 Honourable Mention for Public Works from the Construction Management Association of America.
