BERKELEY, Calif.EM has completed the first of four ongoing cleanup phases at Lawrence Berkeley National Laboratory (LBNL) by demolishing three structures, removing floor slabs and foundations from two previously demolished buildings and remediating nearly 2,700 cubic yards of contaminated soil.

   As part of the cleanup phase, crews tore down a chemistry annex built in the 1940s that provided expanded research laboratory space for housing radioactive substances; an industrial and scientific research facility; and an associated storage facility.

   Under its cleanup objective, EM is scheduled to demolish four additional buildings remaining in the “Old Town” section of the laboratory. Altogether, the seven facilities and remaining floor slabs covered about 48,000 square feet. They date back to the 1940s and were declared seismically deficient.

   No workers sustained injury resulting in missed days of work during the project’s first phase.

   In upcoming project phases, crews will remove the remaining buildings, their floor slabs and foundations and associated contaminated soil, and restore the area for future use. 

   The cleanup is focused on an area of the Northern California laboratory that played an active role in groundbreaking science following World War II. In their heyday, the site’s facilities supported pioneering physics research using the lab’s cyclotron particle accelerator. 

   The project is being completed by EM and the University of California, as the Management and Operations contractor at Lawrence Berkeley National Laboratory.
