Executing an iconic all-glass pavilion entrance to the revitalized Montreal underground retail-dining hotspot at Place Ville Marie was like crafting fine jewelry, says the design-construction team. Submitters note the critical precision required to design, fabricate and build the insulated 630-sq-m glass roof, a record size globally for such a structure.
18屋顶板,每个15 m×2.5 m和weighing up to 5.6 tons, are supported by eight-ply laminated glass beams, with all connectors not seen so the structure appears to float. “There are projects that could be compared, but the main difference is the size of glass and the thickness of the beams, which were never installed like this before,” says Sebastian Keller, project manager for German facade contractor seele GmbH. On a tight and windy site, equipment customized in Germany was used to transport, install and seal panels.
For roof transparency and lightness, pre-glazed structural brackets are hidden in the wall, with panel bearings and spacers obscured by a perimeter fritting. Canopies at roof ends cantilever up to 4.2 m beyond entrance facades, with supporting 14-ply glass beams.
他说，梁内的不锈钢口袋是“我们层压成如此巨大的横梁的最大的（此类）碎片之一”。广泛的分析证实，屋顶将支持冬天的载荷。
To expedite work, panels made in Europe were stored and brought just in time to the site, which was strengthened to support a mobile crane. A custom-made glass lifter fitted with large suction cups was used, as were enclosures for all-weather sealing. Over 10,000 installation hours were logged without injury or lost-time incidents.
该项目必须在PVM办公大楼和市中心进行其他升级。团队指出的预算增加了减少石棉，结构增强和范围变化。
团队说，该项目“为超大玻璃创造了一个新市场。”一位法官认为这是“这类建筑中的重要一步”。
