By setting their sights on Silver LEED® certification, the developers of the Pierre Lassonde Pavilion decided to make environmental friendliness their number-one priority. To satisfy the LEED® program’s material requirements, we integrated 20% fly ash into the cement mix used to build the Pierre Lassonde Pavilion. The ash is a plant by-product, and this gives our product greater value from an environmental standpoint. Tercim, Béton Provincial’s cement mixing plant located in Port de Québec, played a key role in engineering this environmentally responsible initiative.

Built atop the site of the former Dominicans Monastery, the new MNBAQ Pavillion shares one of its walls with the chapel that adjoins the establishment. The project’s architects wished to make this conjoining wall one of the building’s distinctive elements—an architectural component without equal in Quebec with its texture and flawless surface finish. This was no small task, considering that concrete formwork necessarily creates imperfections. “The company Coffrages LD worked relentlessly to build a special formwork to ensure that the wall’s surface would be exceptionally smooth,” said Michel Verret. It took the partners three months to complete this phenomenal structure, built horizontally in a pentagonal, concrete formwork in one single pour, before being hoisted vertically using a crane. At Béton Provincial, an additional technician put his shoulder to the wheel, ensuring that the concrete’s slump value, set precisely at 130 mm, was maintained and that the project was ready for pouring the moment it arrived at the worksite, with no additional water needed. This tricky job was carried off brilliantly, thanks to the flawless execution of the professionals on site. The south-western gable in the Pierre Lassonde Pavilion is already considered “high art” by viewers in the field.
