The purpose of the project was to develop a long-term implementation strategy that would develop a unified and systematic approach for the rehabilitation of the building envelope. The work undertaken consisted of a study and evaluation of the current condition of the Confederation Building based on general visual, non-intrusive inspections and on existing documentation provided by the client, PWGSC. The study evaluated the condition of the exterior masonry walls, the windows, the sloped roofs, the flat roofs and the
skylights relative to the descriptions provided in existing reference reports. An analytical approach was developed to provide three implementation options for the rehabilitation of the building envelope. Remedial works would be scheduled to span 3 to 10 years.
