Penhall Company demolished the 17,500 SF concrete main office and Library of the Los Alamitos High School. The work was done so that a new $55 million dollar STEM (Science Technology Engineering and Math) building could be built. The building demolition had to be performed during school hours. Penhall Company worked expeditiously to ensure the structure was removed with minimal impact to the students or staff. Penhall Company received accolades from the Los Alamitos Unified School District for successfully removing the structures, safely, within the constraints of working on a live High School Campus. In addition to the structures; Penhall Company removed approx. 32,000 SF of concrete paving, and 6,000 SF of concrete canopy.
