Rehabilitation of the Lester B Pearson Building

The Lester B. Pearson Building underwent an extensive retrofit, repair and modernization to introduce sustainable features to improve occupant comfort and energy efficiency, while preserving its historically significant character. Our technical expertise in material and building assessments, energy, heat flow and moisture modelling, and freeze-thaw risk analysis allowed us to provide comprehensive building envelope design guidance for insulation and air tightness improvements of this one million square foot heritage building.

Department of National Defence Headquarters (DND), Carling Campus

The government department required a shift from dozens of downtown locations to one 370-acre ten building campus along Carling Avenue. Morrison Hershfield provided building envelope consulting services including the design and construction review of windows, opaque walls, curtain walls, EIFS, sloped glazing, tunnels, and below grade walls. Our client required a number of items including life cycle cost considerations, ultra-efficient glazing (triple glazing with very low solar gains), security challenges, building envelope LEED considerations, and of course, durability.

Buildings T58 and O276, Ottawa International Airport

Building T58 is a 107,000 SF large hangar facility featuring structural steel trusses that project above the roof level and Building O276 is a 17,000 SF office building. Morrison Hershfield provided building envelope consulting services for cladding repairs and roof replacements at both buildings, including detailed reviews and options for roof replacement, costing, recommendations and construction phasing. We also provided expert review of the construction documents and provided support during construction. (Ottawa, ON)

 
 

British High Commission

The 1960s era window design of the British High Commission was replaced to improve energy performance and better security while also satisfying the NCC requirements for this high profile location in the Nation’s Capital. Morrison Hershfield provided building envelope consulting services in support of the window replacement program and granite cladding stabilization. The client’s goal was adequate installation of blast resistant glazing and verification of the structural adequacy of the existing granite cladding. The team completed site reviews to verify conformance with the design drawings and documented the condition of the granite cladding. (Ottawa, ON)

 
 

M5 Penthouse – 73 Leikin Drive, Ottawa, Ontario

This 830,000 SF office complex consisting of seven interconnected buildings joined by a central atrium required roof replacement. Our building envelope consulting services included new roof assembly design, structural design of the infill of obsolete openings through the steel roof deck, and coordination of the temporary relocation of mechanical and electrical services to facilitate the roofing. We assisted the client with the design, tender, construction and submission of building permit documents and completed periodic review during construction. (Ottawa, ON)
