Project involved the installation of two large diameter directional bores as part of a $75 million Deicing System Enhancement project. The river outfall section included the drilling of a 44” directional bore 1100’ from the airport property to the Columbia River, installation of a 30” HDPE pipe into the directional bore and attachment of an outfall diffuser structure. This was to include pile installation, flange ups and testing.
Additionally Ballard provided directional drilling of 3800 lineal feet of 44” hole under the active International air cargo operations area and the active North-South runway. The continuous pipeline required welding of 6” and 24” fusible PVD pipes 3800 lineal feet in length, and installation of these pipes into the directional bore while not interrupting airport operations.
The Ballard team worked closely with the Federal Aviation Administration and airport operations in addition to multiple sub-contractors to perform this work without impacting air cargo operations.
