DIA Concourse B West

DIA officials have launched a five-year capital-improvement program that includes 39 new gates and renovation of the Great Hall—the airport’s tent-roofed terminal, a central gathering point for travelers and home to a variety of shops and restaurants. The terminal and concourse projects, both begun in 2018, are proceeding as private-public partnerships involving numerous contractors. The Concourse B West project consists of a 3-story, 8,361 square meter expansion including four additional domestic travel boarding gates, four passenger holding areas, a partial basement, and up to 4,180 square meters of paving.

Lerch Bates provided a robust quality assurance program to assist the Turner-Flatiron JV in achieving GCP’s Preprufe Watertightness Warranty of the below-grade sheet waterproofing. Services included certified inspections regularly throughout substrate preparation, waterproofing installation, rebar installation, and topping slab pours.
