Toronto Western Hospital Critical Infrastructure Reliability Project

Toronto Western Hospital (TWH), part of the University Health Network, initiated a project to enhance the reliability of its critical mechanical and electrical (M&E) infrastructure. With aging equipment dating back to 1954, TWH partnered with HH Angus to undertake a comprehensive upgrade project aimed at ensuring the continuous operation of high-risk medical services.

As the prime consultant, HH Angus was responsible for assessing the condition of existing mechanical and electrical systems. Following the assessment, upgrades were made to the facility, including replacing emergency generators, and establishing a new electrical room serving the ORs and the broader hospital campus. Subconsultants, including architectural, civil, environmental, and cost consultants, played crucial roles throughout the project.

To determine suitable locations for generators, extensive investigations were conducted, including structure analysis, examination of building codes, and assessment of environmental impacts. This collaborative effort led to the approval of a new penthouse above the East Wing for generator placement. The final engineering package involved locating the emergency generators at grade in a new fenced area, alongside the supply and installation of two new 1100W emergency generators and upgrades to the electrical network and distribution systems within the powerhouse.

HH Angus leveraged reality capture workflows, utilizing photogrammetry and a Matterport Pro2 camera, to produce a digital 3D model of the powerhouse and infrastructure. Through the efforts of our BIM team, 3D scans were taken of mechanical and electrical spaces, including complex piping and ductwork, to generate point clouds for reference in Revit. These models accurately depict existing systems, including central steam, chilled water, and emergency power systems serving the hospital's ORs and surrounding campus.

Additionally, the project has been recognized for excellence, with the generator exhaust stack winning in the category of Steel Works – Sculptures – Outdoor Pavilions at the Canadian Institute of Steel Construction's Awards for Excellence.

The Toronto Western Hospital Critical Infrastructure Reliability project exemplifies HH Angus's commitment to delivering reliable solutions for healthcare facilities.
