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.

New South Niagara Hospital
New South Niagara Hospital is targeting LEED Silver certification and is being designed to be Canada’s first WELL-certified healthcare facility. The project was recently nominated for two CCPPP awards for excellence in public-private partnerships.
HH Angus is part of the design team under EllisDon Infrastructure Healthcare, the proponent to design, build, finance and maintain the new South Niagara Health Hospital project. The EllisDon Infrastructure Healthcare team includes:
- Leads: EllisDon Capital Inc. & Plenary Americas LP
- Design Team: Parkin Architects Ltd. & Adamson Associates Architects
- Construction Team: EllisDon Corporation
- Financial Advisor: EllisDon Capital Inc.
HH Angus is providing consulting services for conveyance systems (automated guided vehicles, autonomous mobile robots, and vertical transportation) and mechanical engineering as part of the design team. Of special note, we have designed the building’s mechanical HVAC systems to accommodate Indigenous ceremonies taking place not just in a few designated spaces, but throughout the patient care tower, so that patients do not have to be moved in order to take part in healing ceremonies.
The new facility will be a full acute care hospital with 24/7 Emergency Department, diagnostic, therapeutic, and surgical services. The latter will include medical, surgical, and intensive care inpatient beds. Also included will be ambulatory services; post-acute Complex Continuing Care (CCC) Inpatient services; and Centres of Excellence specializing in stroke, complex care, geriatric/psychogeriatrics, and wellness in aging.
The new hospital will integrate technology that supports innovation in and delivery of high-quality healthcare and will be designed to achieve LEED Silver certification. The design will also work toward being the first WELL™-certified healthcare facility in Canada.

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.

Island Health | Infrastructure BC
Quw'utsun Valley Hospital/Quw'utsun Hulitun-ew't-hw (Cowichan)
Three times the size of the existing facility, the new Quw'utsun Valley Hospital (formerly Cowichan District Hospital Replacement Project) on Vancouver Island will reflect BC’s new model for integrated healthcare by placing patients, families and communities at the centre of care decisions throughout the continuum of care. The goal is to reduce wait times, improve care and outcomes, and provide better value for healthcare expenditures.
HH Angus is part of the design team under The EllisDon Healthcare Infrastructure Consortium, and is providing mechanical and electrical consulting engineering to the 607,000+ ft2 project. The new facility, with an estimated budget of $1.44 Billion, will have 204 private or semi-private beds to support best practices for infection prevention and control, with the capacity for increased beds as population growth warrants. The emergency department will be three times the size of the current ER and is expected to accommodate 42,000 visits by 2035. Additional services include mental health facilities featuring a 20-bed inpatient unit and dedicated ICU, culturally safe services and spaces, 7 operating rooms, increased CT scanning capacity, and built-in MRI facilities.
Island Health specified a low energy, low carbon design solution. HH Angus, working with the rest of the design team, devised a number of innovative solutions. The project is now Canada’s first CaGBC-certified 'Zero Carbon Building - Design Standard' hospital and is aiming to be the country's first fully electric hospital. As well, the project is targeting LEED Gold certification.
Sustainability has been at the core of the decision-making process for this project, with a focus on carbon reduction. Its ZCB – Design™ certification reflects achieving a 38% embodied carbon reduction from baseline and, as the first all-electric healthcare facility in British Columbia, the CDHRP’s design has an operational energy performance that significantly surpasses its target.
The design strategies focused on reducing the project's embodied carbon emissions, maximizing energy efficiency, electrifying the mechanical systems, using new-generation low GWP refrigerants, and designing an optimized PV array. The project also uses an air-source heat pump and electric hot water boilers.
This is the first Alliance Project Delivery for HH Angus, with many differences from a conventional project delivery model. It is a far more collaborative process, where the owner, contractor and design team act as one entity. Both the quality of the submitted design and the ability of the team to work together were key factors in the proponent evaluation.
The project is also the first hospital in BC to be certified 'Salmon Safe' for its watershed protection efforts, including reduced water use, on-site stormwater treatment, use of native and drought-tolerant trees, shrubs and plants, as well as enhancing and protecting important wetland ecosystems.
