b'PROJECT ACHIEVEMENT | SMALLBROOK RESTORATION LTD. | CONCRETE STACK REHABILITATION TRANSFER STATION Brook Restorations sky-high expertise was on display while working on Torontos Commissioners Street Transfer Station. The Toronto-based firm was tasked with rehabilitating the interior and exterior of a 127-metre (450-ft) concrete stack while contending with the sites restrictions and extreme weather conditions. This was a unique project due to the location, height and shape of the structure, reports Mike Mulligan, project manager. The project had to be approached with an open mind and the understanding that we would have to redesign and re-engineer our approach on an ongoing basis.Site access, scheduling and coordinating electrical shutdowns with the city and its team partners were among the projectsthe east, Mulligan says.
