The San Diego Airport is currently constructing a new terminal building, which will eventually encompass the footprint of the existing Terminal 1 building, parking structure, and support facilities. Before demolishing the existing structures, asbestos-containing materials (ACMs), deteriorated lead-containing paint (LCP), and universal wastes (UW) such as fluorescent lights, ballasts, and mercury switches needed to be removed from the building.

Geocon conducted a pre-demolition hazardous materials survey for ACMs, LCP, polychlorinated biphenyls (PCBs), and universal wastes across 20 buildings, including Terminal 1, administrative offices, maintenance facilities, warehouses, jet blast walls, and various other structures. The survey involved collecting over 2,000 bulk asbestos samples representing 700 suspected material types, such as fireproofing, thermal system insulation, interior walls and flooring systems, exterior walls, and roofing components. A final report was prepared and submitted to the client, detailing the locations, conditions, and quantities of all identified ACMs, LCP, PCBs, and UW.

Geocon also provided oversight during the demolition phase, which included air monitoring during the removal of various ACMs such as thermal system insulation (TSI), resilient sheet flooring, Transite pipe, floor tile and mastic, and roofing materials. Additionally, Geocon conducted pre- and post-abatement visual inspections for several containment areas and collected over 100 Phase Contrast Microscopy (PCM) perimeter air samples. Clearance air monitoring was also performed within select containment areas, with daily field logs maintained and a final close-out report prepared.

We are currently providing as-needed environmental consulting, oversight, and additional services requested outside the original scope.
