EllisDon London was awarded a Build Finance contract with Infrastructure Ontario / Bluewater Health for the Bluewater Health Capital Redevelopment Project in Sarnia, Ontario, which is the largest public redevelopment project in the City's history.
The 325,000 square foot redevelopment project now provides: an emergency department significantly larger than the current emergency facility; a surgical centre with eight new operating rooms and four new procedure rooms to replace existing surgical facilities; a consolidated maternal infant child program, which will, for the first time, offer labour, birthing and pediatric services on one floor; an 18 percent increase in the number of hospital beds, resulting in a total bed capacity of up to 337 beds; a multi-level bridge will connect the new building with the old, redeveloped building in addition to an atrium style concourse between the two structures.
The challenges of this project included maintaining seamless integration of renovation sequencing, together with fully functioning areas of the existing hospital.
New construction of the expansion portion of the project involved working very closely and cooperatively with two immediately adjacent schools in what is predominantly a residential neighbourhood.
Several measures were incorporated to allow the hospital to ultimately achieve LEED Certified including, but not limited to:
-Recycled reverse osmosis water for grey water use in waste closets
-Low flush plumbing fixtures
-Low volume domestic hot water heating
-Variable speed chillers
-Storm water reclaim
-7/24 water with free-cooling
The existing hospital boiler plant was upgraded as a steam plant with some spare capacity. However, it was not able to handle or be expanded to suit the projected heating loads of the addition. In order to retain the capital investment in the plant along with utilizing any spare capacity, a separate hot water boiler plant was provided for the addition. This plant would serve the heating for are handling units and the perimeter. The existing steam plant was utilized by extending steam piping to the new addition to be used for steam humidification. The result is a fully utilized and salvaged existing steam plant.
The existing chiller plant was insufficient for the expansion and scheduled to be phased out due to the refrigerant. In order to allow the plant to maintain operation, a new location was identified where a high efficiency variable speed chiller plant would be provided. The plant has been planned to allow the switchover to take place off season in order not to cause significant disruption to the existing hospital.
Phase 2 of the project included the interior renovations to 7 floors throughout the oldest section of the hospital which was built in 1944. Some of the key features of the project were:
-New mental health facilities
-New plant Operation facilities
-Human Resources / Financial services
-Hospital office administration
-State of the art air-handling units, supplying the complete building
-Perimeter ceiling radiant panels for heat source that will provide additional floor space throughout offices.
This type of project faced many challenges:
-Maintaining a controlled infection control construction environment throughout existing hospital departments
-Interference with existing departments, i.e. electrical services, mechanical services
-Live services with spaces due to active department within building
-Integrated services from years of renovations and additions
-Controlled inventory of material due to lack of storage
- Pursuing LEED Gold
