The National War Memorial wins Award of Excellence in Conservation Engineering

WSP is excited to announce that Ottawa’s Canadian National War Memorial has won the Canadian Association of Heritage Professionals (CAHP-ACECP) Award of Excellence in the category of Conservation Engineering. The goal of CAHP-ACECP awards is to promote excellence in heritage conservation and to highlight the expertise of our membership as heritage professionals.


The Public Services and Procurement Canada (PSPC) contracted WSP to complete the restoration of the monument and the ceremonial plaza. Designated as a “National Historic Site” and the second most important Ceremonial Centre in Ottawa after Parliament Hill, the stone arch cenotaph stands 23m high supporting two major bronze statues. There were both seismic considerations and conservation restoration challenges to this project.

Dan Carson, Senior Principal, Building Structures, explains,  “Through the use of detailed innovative nonlinear time history engineering analysis, which recognized the rocking behaviour of the Masonry Monument, our team was able to demonstrate the satisfactory seismic performance of the stone monument without needing to add interventions to the existing stone cenotaph. The heritage masonry could be conserved and restored without adding intrusive and irreversible reinforcement to the original structure.”

In addition, a sound foundation of the surrounding landscaped plaza was created allowing the restoration of the ceremonial Plaza. The Plaza rehabilitation was carried out with high performance structural materials particularly selected for durability, reducing the lifecycle cost of the restoration. Thanks to WSP’s innovative design and approach, the project was completed in time for last year’s Remembrance Day ceremony.
