City completes cost estimate for Colliery Dam Park auxiliary spillway

NEWS RELEASE - Distributed February 17, 2016 1:00 PM

Summary

The following update provides cost information associated with the work taking place at the Lower Dam in Colliery Dam Park supporting the construction of an auxiliary spillway flood mitigation solution.

Work at the site began at the end of September 2015 and is scheduled to be completed in April 2016. Due to a limited timeframe during which the spillway could be built, detailed design drawings and specifications were developed in conjunction with active construction. Initial estimates placed the total cost for the project as ranging between $2.8 and $4.6 million.

The complete cost estimate to finish the project on schedule has now been determined with a final cost projected at $4,546,000. A number of factors contributed to the cost nearing the upper end of the initial estimate, including engineering supervision/environmental monitoring during the seven-month project and additional engineering /consultant analysis relating to site conditions.

For the complete list of project costs to date and estimated final costs, please see the background information included with the online version of this news release.
