CIMA+ played a leading role in constructing the Westmount Recreation Centre. Building a large underground arena complex with a park space on its roof was quite a challenge. To achieve this, the structural engineer borrowed from bridge-building methods, creating a green roof fitted with longspan steel girders to ensure the vast empty spaces required for the two rinks could withstand the significant earth pressure. The thermal stability found underground contributed to the LEED Gold certification of the structure.
