Largest Concrete Pour Completed in L.A

LOS ANGELES, Jan 31, 2001 (BUSINESS WIRE) -- W.M. Klorman Construction Corp., an El Monte-based design/build contractor, completed the largest single concrete pour in recent memory at the Howard Hughes Center in Los Angeles.

The project is owned by Arden Realty and developed by Lowe Enterprises Commercial Group, both of Los Angeles.

On Jan. 6, a fleet of 110 concrete trucks converged on site at 7 a.m. In just under 12 hours, crews poured approximately 500 cubic yards per hour totaling 5,600 cubic yards (or 22.7 million pounds) of concrete and laid 700 tons of rebar, equivalent to 130 miles. Along with the trucks, six boom pumps, an 80-ton crane and 225 workers were working in tight conditions more than three stories below street level.

"Klorman developed a logistics drawing of how they were going to locate the equipment, the pumps and the crews," said Daniel Lozano, a 40-year industry veteran and senior superintendent with Swinerton & Walberg, Los Angeles, the general contractor on the project. "I was pleased with the professionalism of the approach. What took place onsite was exactly what they had drawn up on paper."

For a pour of this magnitude, Klorman called upon Southdown Concrete, Brea, whose parent company, Cemex, Monterrey, Mexico, is the third-largest cement supplier in the world.

"This pour is one of the largest we've been involved with," said Skip Keene, territory manager who has been with Southdown Concrete for 20 years. "Klorman's coordination and communication plan maximized the efficiency of the movement of the crews, trucks and pumpers on site."

Designed by Daniel Mann Johnson Mendenhall (DMJM), Los Angeles, the overall project footprint encompasses nearly 100,000 square feet or 2.2 acres. It is composed of a 12-story high-rise office building plus a heliport over a three-story subterranean parking structure which is connected to an eight-story parking structure together totaling approximately 3/4 of a million square feet of floor area. Scheduled to open in April 2002, the structure's unique multi-directional layout and connections to other existing buildings on the site further complicate the project.

"Our company has built several complicated projects. As a result, we have developed solutions to tough site conditions including logistic graphics which were key in the coordination for this pour," said Bill Klorman, president of W.M. Klorman Construction Corp. "We try to plan for as many problems as possible. If and when the unexpected does occur, we can work through it and not jeopardize the schedule."

The structural engineers on the project are KPFF of Los Angeles and Seneca Structural Engineering of Laguna Hills. Innovative Design Group of Irvine is the parking consultant.

W. M. Klorman Construction Corp. is a design/build contractor with offices in Los Angeles and San Francisco. Founded in 1980, the firm is responsible for the construction of more than 150 existing commercial structures as well as numerous developments and renovation/repair projects.
