The Lakeridge project is one of the largest hospital redevelopments in Ontario. A major challenge was phasing the work so that hospital services could remain fully operational with minimal disruption during the construction period. The building project included a new central utility plant, a new twelve floor cancer building, renovations to the existing hospital and fit out of an empty six floor building.
The CUP has 3 – 800 Hp steam boilers weighing 52,000 Lbs each that can be run on natural gas or oil. They operate at 125 PSI and are supplied by an RO system and returned condensate through a dearator. There are 8 – 14” stacks that are 160’ above the roof, 2 are for diesel generators and 6 are for future cogen equipment. The hospital has a completely new building controls system that is monitored from the CUP. The Cancer Building consists of a second level basement that is the mechanical room and electrical room. It holds 8 air handling units, 4 heat exchangers, 8 pumps, and miles of pipe that come from the CUP through the Cancer building to the North Wing. The first basement level contains 8 radiation bunkers, a complete machine shop and offices. The rest of the main floor and up to the tenth floor will be used for offices and cancer treatment.
Renovations to the existing building include the removal of the existing cooling tower from the 10th floor roof and the two 20” condenser water lines that drop through a shaft to the basement. They were replaced with two new 24” lines, four new cooling towers and one plate exchanger to allow free cooling. The new pipe was prefabricated in our new shop and the four 80’ lengths of pipe were shipped to the site and placed into the pipe shaft. Further renovations were tied into the empty building that had been built a couple of years earlier. This work included 8 Operating rooms, emergency, ICU and tenant fit out. The mechanical space includes two 1600 ton centrifugal Chillers and one 650 ton absorption chiller, 10 air handling units, 8 - 50 Hp or greater base mounted pumps.
