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. https://hhangus.com/award-for-excellence/
The Toronto Western Hospital Critical Infrastructure Reliability project exemplifies HH Angus's commitment to delivering reliable solutions for healthcare facilities.

Toronto General Hospital Rapid Assessment Centre (RAC) Expansion
HH Angus was engaged to provide mechanical and electrical engineering, IMIT consulting, and lighting consulting services for this 20,000 ft2 phased renovation at Toronto General Hospital. The space now includes a Rapid Assessment Centre, Diagnostic Test Centre, and Admitting and Pre-Admission Clinics.
The emergency department (ED) was designed to serve ~ 20,000 patients annually but was receiving more than 55,000 patients To better manage these volumes, a dedicated Rapid Assessment Centre (RAC) was added so that ED staff can triage lower acuity patients to the new "fast track" area, enabling primary emergency areas to care for more complex patients. Our team worked in conjunction with the client and other consultants to perform a pre-tender constructability review. This review included potential approaches to minimize disruption outside areas of construction, identify potential installation challenges, and complete pre-demolition of the first phase of work to identify any unknown site conditions in advance of construction. Due to the age of the existing space, there was a high probability of building systems and equipment being beyond their service life, and a certainty that codes and standards relevant to the design of the new space had changed. To address this and mitigate any risks, HH Angus performed a pre-design review to identify any specific potential issues with the new space and recommend steps to further address the unknowns. Scanning and 3D captures were performed regularly throughout construction, using Matterport Pro 2 and a Theta V 360 Camera. This provided the client with regular site progress updates and, in future, will allow for dimensionally accurate references for locating MEP services behind walls and ceilings. It also allowed for a more focused presence on-site, as construction progress was made available remotely to a range of project stakeholders amid COVID-19 pandemic restrictions. The existing ventilation systems presented a significant gap for the project, as their capacity to support the new functions of the space was unknown. To address this, HH Angus investigated and presented several options for review, taking into consideration the client’s budget, schedule, and planned upgrades for existing infrastructure.

Queen Elizabeth II Health Sciences Centre
Bayers Lake Community Outpatient Centre
The Outpatient Centre is part of the $2-billion redevelopment of the QEII Health Sciences Centre. The EllisDon Infrastructure Healthcare consortium led the P3 project. The Outpatient Centre was honoured as a Gold Winner by the 2024 Urban Design & Architecture Awards for its innovation and design excellence, and has also been certified LEED Gold under the LEEDv4 Healthcare rating system.
The Bayers Lake Community Outpatient Centre in Halifax was built as Nova Scotia’s first public-private partnership (P3) healthcare project and is its largest healthcare project to date. Its LEEDv4 Gold certification is the first in Nova Scotia and one of only approximately 50 facilities in the Canadian hospital sector to attain this status. Sustainability features include a stormwater retention pond to capture and filter 100% of rainfall, and an energy-efficient design that reduces energy consumption by 39%.
The Centre provides a range of patient services that do not require a hospital setting, including initial visits with specialists, post-surgery and post-treatment follow-up, blood collection, eye care clinic, physio and occupational therapy, diabetes and orthopedic assessments, rehabilitation services, 17 examination rooms, 24 dialysis stations, and diagnostic imaging (x-rays and ultrasounds). The Centre expects 28,000 clinic visits, and 30,000 x-ray and blood collection visits every year.
HH Angus provided mechanical consulting engineering to the project, which was completed on time and on budget. Kim Spencer, Director of HH Angus’ Healthcare Division, commented that “we were very pleased to be able to support this new facility with HH Angus’ deep experience in the P3 delivery model, and proven track record of thoughtful healthcare design.” HH Angus acted as the prime mechanical consultant, in affiliation with Dillon Consulting, a local sub-consultant. Our mechanical scope of work included HVAC design, with support from Dillon on plumbing and fire protection.

Mount Sinai Hospital
Phase 3A Redevelopment
Phase 3A represented the largest redevelopment in Mount Sinai's history. HH Angus was engaged to provide mechanical and electrical engineering for the Renew Sinai redevelopment.
HH Angus worked with the Hospital, Stantec Architecture and other consultants to develop the Functional Program and Blocks Schematics for Ministry of Health and Long-term Care [MOHLTC) stages 2 and 3.1 submissions.
As part of our scope, we were involved in the investigation of existing infrastructure and systems. The age of the existing facility, together with previous renovations and multiple facility architects and consultants provided a challenge in obtaining a complete set of existing design conditions. We were provided with drawings in various forms (eg: PDFs. scanned hand-drawn images, AutoCAD and part plans), ranging from the original build to the most current renovation projects. We translated the relevant information into AutoCAD and, in with numerous site investigations, assembled a comprehensive set of record drawings detailing the existing systems and functions.
The scope of the project included a new Surgery Department, renovated and expanded Emergency Department, Critical Care, Medical Device Reprocessing Department, Integrated Practice Unit, Ambulatory, and labs, as well as miscellaneous relocates and decants.
Some of the key challenges of this project included reworking the major mechanical and electrical infrastructure to upgrade systems to current standards, and the integration of disparate systems with existing facilities.
Extensive renovations were implemented. To address the challenges of implementing new infrastructure, HH Angus provided extensive background information and on-site investigation to mitigate risks to the Hospital.
Minimizing disruption to hospital services was of paramount concern in scheduling the renovations. To ensure continued hospital operations, our design solution included planned sequential shutdowns minimized inconvenience to staff, patients and visitors.
Under a standing offer with Mount Sinai, we served as Mechanical and Electrical Engineers of Record and were involved in a variety of projects for Phase 3, including: peer review, fluoroscopy unit. Maternity Clinic renovation, Mouse MRI Lab, Biorepository Lab, Roth Lab, Bremner Lab, Distributed Antenna Systems, lobby upgrade, art gallery/ security/office renovations, and IMIT Planning for Phase 3 Redevelopment and renovations to multiple departments.
