Challenges

Planned property redevelopment of a 10-story, Class-A office building slated to house a Fortune 500 Company’s Corporate Headquarters ; construction and final occupancy was delayed due to the presence of elevated concentrations of methane in the subsurface related to backfilling of a historic quarry and disposition of “lake fill.”

Conducting methane monitoring during building foundation construction

Design, installation, and testing of a sub-slab Vapor Intrusion Mitigation System (VIMS)

Solutions

Comprehensive due diligence that included expanded historical review, extensive soil vapor characterization, engineering design of an active Vapor Intrusion Mitigation System (VIMS), and routine agency communication to maintain and drive schedules. TGE designed the system, obtained permits, assisted with installation contractor selection, oversaw construction, conducted compliance monitoring, and certified the system.

Outcome

TGE met project objectives, the system “passed” all engineering tests, and proved protective for site conditions – a satisfied client and tenant.
