This project involved expanding and upgrading the wastewater treatment plant (WWTP) in Gitxaala. I was responsible for preparing the initial structural upgrade plans and developing a Class D cost estimate for the proposed expansion.

What I did

  • Initiated discussions with process mechanical, electrical, and building mechanical disciplines to understand the full implications of the WWTP expansion on cost.
  • Reviewed existing facility plans and analyzed relevant building codes and regulatory requirements to identify potential challenges and cost impacts early.
  • Compiled a detailed cost spreadsheet by synthesizing input from all disciplines. Focused on identifying and quantifying the significant cost items.
  • Organized a teleconference with the client to review and clarify the assumptions behind the cost estimate.
  • Benchmarked the overall projected cost against cost-per-area metrics from the Altus Canadian Cost Guide.
  • Issued the final Class D cost estimate to the client.

Outcome

  • The client agreed with the proposed Class D cost estimate. This established a reliable financial baseline for the project.
  • My estimate set the stage for continued involvement in providing progressively more accurate cost estimates as the project advances through later design stages.
