To upgrade the capacity of UBC’s low-carbon sustainable energy system, e design-built a 12-megawatt biomass boiler system that was retrofitted into their BRDF plant. Using 3D modelling, we employed a staged approach on this complex installation into a functioning plant. All components were brought in through a 19’x24’ door or lifted and positioned through openings in the roof. While the unit bases were prepped, the boiler and electrostatic precipitator (ESP) components were suspended 20’ above ground. Once the 60’, 130-tonne boiler was in place, we installed the ESP.
