Les Terrasses de la Chaudière (LTDLC) complex, built in 1978, is composed of four office towers located in downtown Gatineau, Quebec. The buildings consist of reinforced concrete structures covered with prefabricated brick veneer panels that form most of the building envelope. It is the largest federal office complex in Canada, with a gross area of almost 1.8 million square feet, and accommodating more than 6,000 people as well as retail, daycare and storage space. The four towers are 7, 19, 19 and 28 storeys high, with some multilevels in between.
This major rehabilitation project consists of replacing the roofs, exterior brick wall assembly, penthouse cladding, and the windows of the complex. The work will transform LTDLC into an energy-efficient and modern complex. Once the work is completed, the complex will have a predominantly glass and aluminum façade, with wood elements on the inside of the windows, positively enhancing the exterior aesthetic.
Scope also includes mechanical/electrical interfaces, interior finishes affected by the envelope work, and post-construction landscape rehabilitation.
The complex will remain occupied throughout construction.
