Chosen as "architects of the year in 2015" by the Royal Architectural Institute of Canada, the Provencher_Roy team is composed of more than 200 multidisciplinary professionals who have established themselves as one of the preeminent architectural practices in North America.  Since its inception, the team at Provencher_Roy has consistently applied their knowledge and expertise in the field of architectural design resulting in an impressive portfolio consisting of universities, museums, hospitals, airports, hotels, conference centers, detention centers, sports facilities and numerous other award winning projects. In addition to its architectural practice, the office has continuously expanded its expertise by developing internal departments in urban planning, interior design, industrial design, landscape architecture and technical innovation, which has led to its work being recognized by more than 80 awards, honors and distinctions over the last 34 years.


Since its foundation in 1983, Provencher_Roy has established itself as a precursor in the world of architecture in Quebec. By striving to find innovative approaches to the impact that every architectural proposal has on its environment and on the community as a whole, the company has continued to remain relevant and contemporary by retaining a holistic vision of architecture which is rooted in modernity yet is open to adaptation. Through its openness and this constant commitment to innovation, the team of P_R has adapted its practice to the major transformations to which the project implementation process has undergone over the last decade.


The arrival of the BIM in the field of construction represented a true paradigm shift; it redefined the way that P_R approached their projects.  Although the term appeared in the 1970s in the United States, it took many years before this conceptual and technical advancement became a reality. BIM has now become an integral part of daily practice and the office has been working with it for a little over 10 years, which puts P_R among the pioneers in Quebec. They have thus been able to experiment and collaborate with numerous other teams in order to develop strategies and protocols allowing them to reach different levels of BIM achievements, from the most basic (parametric 3D modeling) to complete integration (assembly and interoperability of Models of all the participants), resulting in true simulations of a project thanks to a virtual prototype.


Provencher_Roy believes that it is essential to understand, integrate and share this process in order to guarantee a better visualization / understanding of the project as well as a better collaboration / coordination. 


Olympic National Park, Montreal

Provencher_Roy was mandated by the Régie des installations olympiques in 2015 to renovate the iconic Tower of Montreal of the Olympic Park. Built in 1976 by the French architect Roger Taillibert, it was not until 11 years later that the tower was completed (in 1987) to support the retractable roof. In keeping with the nature of the sports activities that were intended to take place there, the opaque parts of the outer envelope were made with prefabricated concrete panels, while thin strips of high windows were installed to allow zenithal lighting.


After 30 years of being inhabited, the Tower is being reconfigured to host the cooperative financial group Desjardins’ offices in 2018. As part of the project, the Tower of the Olympic Stadium will face a major shift in use: from an existing sports facility that has never been used, it will now accommodate office spaces for about 1000 employees. This new workplace will bring life, activity and energy to this Montreal icon.

The new use of the tower, i.e. "office" type workspaces, requires additional natural light. To this end, the existing envelope, consisting predominantly of precast concrete panels, must be removed to make room for a new concept that emphasizes fenestration to maximize natural light penetration to the center of the tower.

The specific aspect of the existing volume and features of the tower is emphasized by the unique nature of the shape and movement of the forms as they twist and turn. In order to avoid curved glass, the solution was to extend existing slabs on each floor in order to achieve a parallel geometry from floor to floor.

The mandate required delivery of a successful project in an accelerated schedule with sometimes limited information due to it’s complexity. In order to simulate the new curtainwall and therefore aid collision detection at the initial stage, the first step was to collect 3D data, using laser-scanning surveys to capture accurate measurements and create an accurate working model. Point clouds were generated (of the envelope of the building and at each floor on the inside of the tower) to allow us to model the existing tower using Revit.


The design team (architect, structural and building services engineers, surveyors) translated the point clouds data into a full 3D building and data model. We modelled the envelope and the structure. We handed over the model to the main contractor for construction management.


The construction model was managed over the cloud by the contractor in BIM 360 Glue. The subcontractors from every trade were required to input critical information into the model before the construction had even started. ‘’Clash detection’’ has been surveyed throughout the process to avoid discrepancies, limit conflicting information and coordinated with the professionals and different trades.


Considering the existing building complexity, we used another cloud service, BIM 360 Field, for issue management, quality and handover making the construction a success until now.



Over the past ten years or so in delivering BIM projects, BIM managers and daily BIM users got the chance to experiment with new technologies on a wide range of projects and constructions. From basic design iterations, to advance calculation methods to evaluate construction cost and schedule, program and data sheet compliance, as well as high-end visualization methods, clients have helped push the smart use of technology in the construction industry in eastern Canada.


Software 101: Randomize façade

In 2012, while designing the main facade of a military research facility in Québec, the project required the production of a random distribution pattern of façade panels on the main entrance of the building.

The randomization through software such as Grasshopper and Rhino was not a difficulty, but reproducing it in Revi
