New scope of work for custom team
MOSS LANDING– The Construction Division’s custom team stretched beyond its normal scope of work to win a project at the Moss Landing power plant.
The circulatingpumps VFD (variable frequency drive) building project for Dynegy Moss Landing led electrical, structural and civil engineers to design this job to lower the energy pumping costs to draw and circulate 1 billion gallons of ocean water daily to generate power.
Dynegy contracted with Pioneer Custom Electrical Products of Santa Fe Springs, Calif. to manufacture a medium voltage VFD system housed by a 53-foot-long, 16-foot-wide pre-manufactured building, weighing approximately 55 tons.
Graniterock successfully delivered all milestone timelines.
The most critical milestone was the 5 feet over excavation, engineered pad and 12-inch thick concrete pad by the mandated Sept. 21 date.
Graniterock’s concrete team, headed up by Mike Chernetsky and Willie Diaz, supplied 5,000 psi concrete that hit the first seven-day break at 3,700 psi and 4,500 psi at 14 days.
King Crane’s crew used a 275-ton crane to safely place the building on the concrete pad within an inch of the target, which was marked with blue painter’s tape to show where the building should be placed.
The balance of the project includes grading, storm drain, concrete steps/ramps/flatwork, base and asphalt paving.
“This is an exciting new direction for us,” Estimator/Project Manager Steve Lindsay said. “The whole team has worked really hard out here, proving we can be successful at this type of structural and civil engineering work.”
This is one of five projects the custom team will complete for Dynegy this year.
The Moss Landing project is expected to finish in late December, depending on the weather.
Thanks to Ed Jenkins and Craig Gebhart for leading the team of Kurt Lanning, Jorge Sanchez and Joel Chavez-Lobato, all of whom helped make this job a great success.
