Assisting The Rescue

RICH GARLOCK: LERA's founder, Leslie Robertson is the structural engineer of record for World Trade Centers 1, 2, 4, 5, 6 and all subgrade levels. Thus, Leslie E. Robertson & Associates (LERA) had all of the architectural and structural drawings for the complex in our office and our personnel had an intense knowledge of the complex. In the initial days and weeks after the event, all of LERA's engineering was directed towards supporting the rescue effort — getting drawings into the right hands, helping rescuers who were looking for survivors navigate the unstable debris to prevent further loss of life.
