The design team implemented an innovative cost reduction tactic for new apron pavement sections at the aircraft parking gates. Aircraft-rated pavement PCC is used for areas at the heavier rear of the aircraft, while the nose gear stands on a much thinner rated PCC pavement to reduce installation costs and time across the 14 gates.
To minimize operational impacts, the pushback taxilane area and connector taxiways used an asphalt pavement section for ease of construction and to minimize closure within the operational Taxiway Safety Area (TSA) and Taxiway Object Free Area (TOFA). This allows airport operations to return to normal much sooner. A further benefit is landside construction laydown and work areas on the congested site are available longer.
The peak workforce will be nearly 800 workers, requiring space for equipment, material storage and worker parking to meet the opening schedule. By reducing the duration of the Taxiway A connector pavement construction, the team maintains the existing Air Operations Area (AOA) fence security for longer and avoids reducing the available landside shortage areas.
