The National Library & Public Archives of Canada is entrusted with many of the most important documents throughout the history of Canada. The main building where the public can obtain access to these records and documents is located at 395 Wellington Street. The building was officially opened in 1967. The auditorium within this building is frequently used for various events and presentations. Above the auditorium is a series of catwalks that provide access to lighting and electrical sources. Cleland Jardine Engineering Ltd was retained to provide a review of the catwalks to highlight any safety hazards that may exist. The existing catwalks were found to only have a guardrail on one side and the guardrail was found to be not sufficient enough to resist the guard loading according to the current Building Code. Cleland Jardine Engineering Ltd designed a new steel guardrail which was installed on the side with no guardrail and designed reinforcement for the existing guardrail so that it could now resist the required loads.
