Canada | Zahner

350 Sparks

350 Sparks; Ottawa, Ontario

A short walk from Canada’s Parliament buildings in Ottawa, Ontario, the team of B+H Architects and Morguard collaborated with Zahner to enhance the experience of entering their office complex at 350 Sparks. The installation of custom perforated wall art showcases the journey along the Ottawa River adjacent to Parliament Hill.

Zahner supplied 1,563 visible square feet of custom perforated aluminum panels and associated sub-framing (painted) for installation by the GC/Subcontractor. The ImageWall panels feature perforations through the panel joints, thus making the imagery dominant to the viewing eye.

Fairmont Pacific Rim in Downtown Vancouver BC, Canada

Located in downtown Vancouver, BC, Canada, a 44-story hotel was designed by James KM Cheng, just blocks from the Pacific Ocean. Zahner became involved when the architects opted for a perforated screen system which would disguise the first few floors of office and parking structures, while allowing light and air to enter through the thousands of tiny perforations.

What sets this perforated screen apart from standard fare is its unique surface design, a patterned perforated and bumped texture which subtly glistens across the surface. Architects wanted to solve two problems with one solution: creating a parking garage with an open air-flow, and an artistic facade surface that reflected the building’s natural surroundings.

Using Zahner’s patented ZIRA system, architects supplied Zahner with a photograph of the surrounding forest. The image was transferred onto the metal using perforations and dimples in the stainless steel. All across the building’s structure, trees create vertical lines running up and down the facade, and the forest emerges.

Translating the Image to Metal

The architect supplied a photograph of redwood trees taken in the surrounding nature of Vancouver, pictured below. The image was translated using software originally developed by Zahner for the de Young Museum in San Francisco.

The translated image data was applied across the metal surface algorithmically to account for panelization. Each of the perforated metal panels is designed with metal flange details that the ZIRA™ Process had to account for in the process of translating data. The image flows seamlessly across these panels and around the building’s corner edges.

The architects wanted to create a rippled effect with the metal, to create a surface both luxurious and functional. Using the ZIRA Process enables the architect to create this surface at a cost not much higher than a uniformly perforated surface.

No panel is the same, and the pattern never repeats itself across the stainless steel surface. Both the perforated surface as well as the bumped and dimpled texture were produced using a system of CNC-controlled punches and dies.

Art Gallery of Alberta

Art Gallery of Alberta in Edmonton, Canada

The Art Gallery of Alberta (AGA) is a Canadian Museum in downtown Edmonton which features a Zahner-manufactured curvilinear canopy and building envelope system. The building was designed by Randall Stout Architects with local firm HIP Architects in Edmonton.

Zahner’s scope included a massive ribbon of stainless steel which wraps around and through the building. Known as ‘The Borealis’, this curvilinear form evokes the Northern Lights, a frequent phenomenon of the Edmonton night sky. The borealis snakes through the gallery’s interior and emerges above the building to form the roof’s canopy, and then drops again to serve as a “snow cone,’ collecting snow and ice.

The sleek curving borealis is paneled in a stainless steel skin system developed by Zahner. The applied non-directional surface treatment of the metal gives the building its muted glow, reducing and nearly eliminating any harsh glare from the sun.

The ‘borealis’ is engineered using ZEPPS technology, a system developed by Zahner to simplify the construction of complex structures and facades. For a curvilinear form that wraps around and within the building, an intelligent structural system was required to handle the curves and handle all structural loads. These fully pre-assembled megapanels were delivered to the site so that the local installers could easily install the pre-fabricated panels.

The building also features a variation on the Hunter Zinc preweathered patina on zinc. This surface is used throughout the interior and exterior on flat and geometric surfaces. It is similar in appearance to slate or limestone.

Making the Art Gallery of Alberta

Zahner is one of the few organizations in the world that has a dedicated team for handling design-engineering processes. Design Assist divided the project and translated the architects’ intent into engineered subsections and parts which the draftsmen and project engineers can then rapidly push to the fabrication facility.

Design Assist produced several scale mockups of both the flat-lock zinc siding as well as the curvilinear Angel Hair stainless steel surface. These mockups give a sense of the upcoming quality, as well as aid in identifying potential problems and develop essential solutions.

Zahner design-engineered, fabricated, delivered the components of the Art Gallery of Alberta for intelligent installation by the Canadian installers. This process was made possible by intensive design consulting sessions early in the planning process, facilitated by Zahner Design Assist.

Design Assist | BIM to Build

As the construction world continues to move towards digital and cloud computing, Zahner fully integrates into Building Information Modeling (BIM) frameworks, so that all participants are aware every stage of construction.

The structure for the Art Gallery of Alberta was divided into several complex components, and to keep the entire project organized required a strong BIM foundation. Drawings from the architect were digitally defined and refined into a working model which served to involve every aspect of its construction.

This makes complex components, such as the architectural metal wing flying through the window, possible (see below). Coordinating multiple trades is one of the big strengths of BIM. It also plays a large role in condensing the construction down to its essentials.
