Airfield Capital Development ($100M)

Existing runway 16L/34R is the longest runway at Sea-Tac Airport at 11,901 feet, able to accommodate all aircraft, yet essential for long haul passenger carriers and heavy freighters. Originally constructed in 1944, 16L/34R has undergone various extensions and improvements, including an overlay in 1992. Apparent deterioration from aging and heavy use requires reconstruction.

The activation of 16R/34L, the new “Third Runway”, enables Sea-Tac Airport to close 16L/34R during the 2009 construction season for reconstruction while maintaining the operational capacity of two runways.

Goal

Provide a safe, durable and long-lasting runway for Sea-Tac Airport to move airlines, people and air cargo, eventually supplying The Port of Seattle with a three-runway system to boost commerce and support increased air travel.

Project

Provide Construction Management for the complete reconstruction of Runway16L/34R, which will include:

  • Portland Cement Concrete pavement with asphalt concrete shoulders
  • New Airfield Lighting Vault
  • Third Runway Storm Water Pond Facilities Conversion
  • New FAA Runway Status Light System, including intersecting taxiway work
  • Des Moines Nursery Site Mitigation

The project also includes: infrastructure replacement involving electrical, communication, water, industrial waste, and stormwater components. The existing stormwater system for 16L/34R will be modified to provide improved runoff water quality by using the grassy infield areas for natural water treatment.

 

 Status
All airfield projects managed by Shen Consulting on the 16L Program, including the FAA status lights, runway reconstruction and stormwater pond conversions, were completed on schedule and on budget.
