ABSTRACT
As part of the Metro Vancouver (MV) Annacis Island Wastewater Treatment Plant (AIWWTP) expansion, two new Gravity Thickeners are to be designed and constructed. The area of this planned construction is in an older area of the plant and understanding of the presence and position of underground utilities and other features here is incomplete. Surveys with electromagnetic-based (EM) technology (e.g., Ground Penetrating Radar or GPR) have been unsuccessful due to soil conditions at the plant. Brown and Caldwell utilized an emerging acoustic technology, developed by Cartacoustics, LLC, to detect, locate, and map the position of underground utilities and other features in the area of the planned construction. These results will be included in design and construction efforts and will help prevent unwanted strikes and costly change orders.
