Project Description

The Vaughan Mainline Expansion added an approximately 11 km natural gas pipeline section through Vaughan, Ontario. Construction included three significant horizontal directional drills, including crossings beneath the Humber River and a tributary, along with nine slip bores beneath roads and railways.

TULLOCH's survey crews supported property and right-of-way definition in this complex corridor, where accurate deformation monitoring was also required at major crossings.

Scope of Services

  • Lot-fabric retracement
  • Staking of right-of-way limits
  • Individual ownership sketches and plans of survey where required
  • Survey support and deformation monitoring associated with major crossings
