Ottawa Lockstation Masonry Repairs | City of Ottawa

The project will stabilize historic masonry retaining walls at Ottawa Lockstation, specifically the East Retaining Wall at the Commissariat Building, and the large retaining wall on the East side of the locks. Work will include raking, pointing and grouting as required. Work will take place in the fall and winter seasons to reduce the impact on residents and visitors. The goal of this project is two-fold: the preservation of historic structures that make up the fabric of the City of Ottawa, and the remediation of potential safety issues with respect to the stability of these structures.

This rehabilitation project will entail the concrete rehabilitation of both structures.

Black Rapids Dam | City of Ottawa

The Black Rapids Dam is an overflow structure located in the nation’s capital on the Rideau River. This rehabilitation project will involve repairs to the concrete structure as well as improvements to the shoreline concrete wall adjoining the dam. This will ensure that the dam remains reliable, functional, meets current codes and standards, and that water management capabilities are optimized.


Black Rapids Lock 13 | City of Ottawa

Black Rapids Lock 13, located in the Nation’s Capital, is considered a cultural resource of national significance, meaning that it has a direct relationship with the reasons for the designation of the Rideau Canal as a national historic site. Timber lock gates were installed at the lockstation in 1969 when the lock was also mechanized. The intent of this project is to repair masonry and concrete in the lock chamber, to replace the lock gates which have been in place for 47 years of service and to upgrade the hydraulic operating system for this lock. This project was previously announced.
