Colliery Dams Update

NEWS RELEASE - Distributed October 30, 2015 2:00 PM

Summary

Golder Associates and Herold Engineering have completed the “Issued for Review” design drawings for the auxiliary spillway and bridge structures. The drawings have now been sent to the Province's Dam Safety Section for their review. Upon completion of the Dam Safety Section’s review, engineers will make any necessary revisions and the drawings will be issued for construction.

In addition, installation of the secant pile cut-off wall is half way complete. Copcan's subcontractor, Henry Drilling, is making faster progress than originally anticipated. Completion of the wall is now anticipated by November 6th. Once the cut-off wall reaches the minimum required concrete strength, the excavation for the spillway and bridge structures will begin. The excavation will be followed by the concrete formwork, rebar placement and concrete pouring.

Quotes

"The weather is cooperating and construction of the secant wall is proceeding better than expected. Once the issued for construction drawings are in hand, construction schedules will be developed for the remaining work. With this work comes more construction activity and a further safety reminder for park users to follow direction from workers on site and to observe posted signage."
