Palliser One Recladding
Palliser One is an existing 27-storey commercial building in downtown Calgary.
The building was built in 1970 and consists of a reinforced concrete structure with two-storey precast concrete cladding panels and punch windows.
The owner, Aspen Properties, identified the need for the full removal of the existing precast concrete cladding and window systems and replacement with a new aluminum and glass curtain wall system.
Following this study, Aspen engaged Gibbs Gage Architects to continue their earlier concept designs to execute the recladding in 2016/2017.
Entuitive was engaged to provide building envelope and structural consulting through the design and construction phases.
As a first step, Entuitive was retained by Aspen Properties to complete a feasibility study for the recladding project. Our role was to review the existing structure and building envelope, and to provide recommendations on the cladding removal so new cladding installation could be undertaken.

KEY CONSIDERATIONS
Challenge One
For the foreseeable future, the building is +/-95% occupied, therefore, the client impressed upon Entuitive that the recladding must be completed predominantly from the exterior.
Typically, recladding projects of this extent are completed by constructing a temporary wall, as a safety and weather barrier, and interior of the existing exterior walls, allowing the recladding to occur from both the interior and exterior. However, this method was not feasible in an occupied building without great disruption to the tenants.
Solution One
As part of Entuitive’s scope for the feasibility study, we reviewed various options for removal of the existing precast concrete cladding panels and installation of new curtain wall, all from the exterior. We were able to develop options for this work and provided a recommendation that allowed all work to be completed from the exterior, while maintaining visible light through the existing windows throughout the project, and limiting only the work inside tenant spaces to be final interior finishes.
