Colliery Dam Cost Estimates For Rehab & Rebuild

 Action Plan for Colliery Dam Concepts

City staff continues to carry out Council’s direction from the December 17 regular Council meeting to engage professional engineers to undertake conceptual level cost estimates for rehabilitating or rebuilding the Colliery Dams concurrent with engineering design and environmental study work to remove the dams and re-naturalize the Chase River.

The current status of the two-stage action plan announced December 24, 2012 is as follows:

1.       Klohn Crippen Berger (KCB) was retained to undertake conceptual level cost estimates for the Colliery Dams.  KCB has extensive experience with the assessment, design and construction of dams, are familiar with the recent studies and assessments of the Colliery Dams, and have excellent knowledge of British Columbia’s Dam Safety Regulations and Standards. KCB was also retained to carry out the design work necessary to fulfill the proposal to remove the Colliery Dams.

2.       The City has issued a Request for Proposal for the purpose of hiring an engineering consultant to complete a peer review of KCB’s cost estimating work. The peer review will involve an assessment of the concepts being considered for rehabilitation and rebuilding. Based on that initial assessment, KCB will then develop the conceptual level cost estimates. Those cost estimates will also be subject to the peer review process. 

During the months of December 2012 and January 2013, City officials, along with members of the Province’s Dam Safety Branch, met with a delegation of community members seeking an alternative solution to removing the Colliery Dams.  Through the two-stage action plan outlined above, the community delegation will be invited to provide input to the peer review engineer, who will then work with KCB on the alternatives to be developed.   The City also remains available to meet with the community delegation should new information be identified.

The City anticipates both stages of the action plan will be completed by mid-April, with the opportunity to share information with the community delegation occurring in late February or early March.
