REMOVAL & DISPOSAL OF AN AERIAL PIPELINE CROSSING

Owner: Terasen
Value: $600,000.00
Description: The work involved removing an aerial pipeline that crossed the Columbia River in Castleger BC complete with pipeline, towers, suspension cables and concrete foundations and anchors.
Location: Castlegar, BC

The project involved the removal of an obsolete pipeline over 1000’ long and suspended between two towers over a very sensitive river without touching the water.  This posed a large number of technical difficulties but Johnston Construction was up to the challenge.

A leading BC Bridge Engineering Firm was brought onboard to work closely with Johnston Construction’s experienced in-house Project Management team and technical staff to prepare a detailed work plan.  This work plan addressed all the technical challenges of the project while still maintaining the tight timeline and adhering to a strict environmental policy.

The work plan involved four major phases:

  1. The removal of the gas line from the suspension structure
  2. The removal of the suspension wires that spanned the Columbia River and had supported the gas line.
  3. Removal of the suspension towers, wind brace towers, guy lines and all associated anchors and foundations located on the banks of the river.
  4. Site cleanup and revegetation
