Construction of a modular building, site services and six parking spaces at Rideau Hall

The Royal Canadian Mounted Police is proposing the replacement of existing facility trailers with a modular building to support security requirements. The modular building is complete with water, sewer, natural gas and electrical services, and the addition of six parking spaces at Rideau Hall in Ottawa, Ontario.

The proposed project would take place on lands owned by the National Capital Commission and is subject to a federal land use, design, and real estate transaction approval under the National Capital Act.

The modular building would be approximately 24 feet wide by 60 feet long, require a granular rock base, concrete piers, minor grading, connection to nearby utilities and landscaping. The six parking spaces would also require a granular base.

The construction area will be accessed with machines and equipment, and all work areas will be fenced accordingly. Construction is set to begin in fall 2022, with a completion date of March 31, 2023. Construction work will follow all municipal by-laws, including those related to noise. The project will be submitted to the Federal Heritage Building Review Office (FHBRO) for review. Recommendations from the FHBRO will be incorporated into the project.
