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. 

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.

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.

Thunder Bay Correctional Complex (TBCC)


The TBCC involves replacement of aging jail and correctional facilities with a new 345-bed, multipurpose complex. Both the existing Thunder Bay Jail and Thunder Bay Correctional Facility are among the oldest provincially-run adult correctional facilities, built in 1928 and 1965 respectively.

The new TBCC updates automation and technology to address issues of health, safety and security, and introduces efficiencies around design, technology, and the use of space. HH Angus is providing mechanical consulting engineering and vertical transportation consulting to the EllisDon Infrastructure Justice design team.

The TBCC is targeting LEED Silver certification and LEED Resilient Design pilot credits through the United States Green Building Council. The design focuses on energy efficiency, healthy indoor environments and reduced greenhouse gas emissions. The complex will also include views of nature, allow ample natural light and feature dedicated Indigenous cultural spaces, such as smudging space and sweat and teaching lodges.

The new facility is the first of its kind for an Ontario correctional facility, incorporating design features that promote rehabilitation of inmates. It will also improve access to programming, living conditions and education, while updating automation and technology.

The TBCC project has presented several challenges to our design team, including a compressed schedule and the involvement of numerous stakeholders. It has also been interesting on a technical level: mechanically, the various modes of operation and interconnection of systems are quite complex, necessitating a high degree of flexibility within the capacity of the mechanical equipment. The building construction featured a precast exterior with block walls, requiring very close coordination with trades to align openings and allow access for equipment.

Due to the secure nature of the facility, the mechanical system was integrated seamlessly into the architectural features, all accessible equipment is provided in a secure location, and all building systems interact
with the BAS.

The facility will include a connection to an existing 50-inmate facility — the Thunder Bay Modular Built Facility — located southeast of the TBCC and currently under construction. The project also involves the design and construction of a 4,000 ft2 wastewater treatment facility to allow for a fully self-sufficient and self-contained facility.

Royal Inland Hospital

New Patient Care Tower

Royal Inland Hospital is a tertiary level acute care hospital serving a catchment area of approximately 220,000 residents in the city of Kamloops and throughout the Thompson, Cariboo and Shuswap regions of British Columbia.  

The 290,625 ft2 new Phil & Jennie Gaglardi Patient Care Tower (PCT) is a nine-storey building that includes a surgical floor, 13 operating suites, patient floors for mental health and medical/surgical beds, a neurosciences and trauma unit, perinatal centre, labour and delivery rooms, and neonatal intensive care unit. There are also two underground parking levels, administrative and clinical spaces on three lower floors, an intermediate mechanical floor, and 3 inpatient levels topped by a penthouse containing the heating, cooling, and emergency power plant.

Phase 2 consists of a number of renovations within the existing facility, including a completely renovated Emergency Department. Phase 1, which opened in July 2022, has achieved LEED Gold certification. HH Angus provided mechanical and electrical design services for the PCT, which was constructed adjacent to the existing hospital under a P3 contract.

Designed with direct input from local healthcare workers, the PCT streamlines access to hospital services through a single main entrance. A new post-anaesthetic recovery room in the adjacent existing facility’s renovated space will be constructed in Phase 2. Other clinical spaces include a substance use inpatient unit, a child and adolescent mental health crisis intervention program, maternal and child services, and respiratory therapy services. Non-clinical spaces include reception, patient registration, a rooftop helipad, underground parkade, retail space and a new home for the Royal Inland Hospital Foundation.

The mechanical design included energy-efficient heating and cooling systems with a variety of heat recovery features. The project had an ambitious energy use target and HVAC systems were designed with this benchmark in mind. Current estimates predict 24% savings in energy costs.

HH Angus was able to solve a problem the Hospital was having with the existing distributed hot water boilers by upsizing the new plant to serve the majority of the hospital campus. The ventilation design includes redundant capability and outbreak control, and exhaust air heat recovery, as well as providing for future flexibility.

The Health Authority expressed an interest in the ability to conduct smudging ceremonies in any patient room without having to make significant modifications to the current ventilation design and infrastructure included in the project.  HH Angus found a means for using the ventilation system as originally designed and applying a unique operational sequence to minimize capital cost changes while providing the ability to undertake smudging activities in any of the patient rooms on the Medical/Surgical and Mental Health Adaptive inpatient units.

A central focus of the design team was to work with the commissioning team to ensure proper operation of the new facility. The design team is now helping monitor ongoing operations to recover and reuse as much waste heat as possible. This effort concentrates on the heat recovery chiller plant operation to meet as much of the building’s heating load as possible using waste heat. This contributes to minimizing the production of GHGs from heating energy sources and, in turn, improves decarbonization for the new facility. New electrical services include a 25 KV service from BC Hydro serving a new outdoor substation powering the existing campus and PCT. New redundant 25kV to 600V FR3 transformers feeding the new tower were provided in the new main electrical room. Three new 2MVA diesel generators provide emergency power backup to the new patient care tower and the rest of the existing campus if utility power is lost. 600V distribution on both utility and generator power are provided with high resistance grounding to increase resiliency and reliability in the event of a single ground fault. Numerous low voltage systems were provided including fire alarm, lighting control system complete with daylight harvesting, circadian rhythm tunable lighting in the Neo-natal ICU, and electrical metering.

Helipad Design

The rooftop helipad is served by a number of mechanical and electrical systems to help keep the pad surface clear of snow and ice and to provide appropriate safety lighting to meet all requirements. Fire protection and life safety systems, such as foam suppression, were carefully coordinated and designed to ensure full coverage and containment in the event of a discharge.

Systems Integration

 Integration with the existing hospital systems was a significant challenge and required numerous connections to the adjacent facility. Requiring multiple site visits, it was determined the two facilities could be successfully integrated by enclosing an outdoor courtyard between them, transforming it into a four-season space that will benefit patients, staff and visitors. On the electrical side, backfeeding the existing facility with new 600V HRG generator backup required careful analysis of existing distribution to ensure compatibility for all existing equipment to the new 3 wire distribution on emergency power. A detailed sequence of operations for black start sequence and retransfer of automatic transfer switches to normal was developed and commissioned to ensure proper operation for different failure scenarios.

Town of Oakville

Fire Hall #8

This project was designed and constructed under the Integrated Project Delivery procurement model, a methodology that, in our experience, provides excellent results for our clients, as well as fostering greater collaboration within the project team. 

Oakville’s new fire station and amenities have been designed to serve a growing population. LEED Silver certified, the 1.5 storey facility was almost fully constructed from glue laminated and cross laminated timber (CLT). CLT is a relatively new construction material in North America; CLT panels/walls are fabricated off site, where all M&E openings and penetrations are cut out, and then subsequently assembled on site. This approach required extremely close coordination between the structural designers and the M&E designers since, unlike drywall, wood openings cannot be adjusted once cut. The modular construction approach also helped meet the aggressive schedule for this project.

HH Angus’ mechanical scope included variable refrigerant flow, energy recovery ventilators, infrared tube heaters, and vehicle exhaust system. Electrical systems include natural gas backup generator, daylight harvesting sensors, provision for solar PV, CCTV and card access, and fire locution (radio system for 911 dispatch). Special provisions were made to allow speakers to be installed strategically throughout the building to support the locution/fire alerting system, with additional provisions for the radio antenna. In 2021, the project was honoured with the Toronto IES Illumination Section Award. 

The fire hall floor plan consists of three fire truck bays - two drive-through and one back-in bay, gymnasium, dormitory, kitchen, offices, meeting rooms, IT room, and many specialized service spaces. Fire Hall #8 is designated as a “post disaster building”; hence, the M&E systems are very robust. 

Perhaps ironically, the new fire station is clad in charred wood. Shou Sugi Ban charred siding, made from logs reclaimed from Ontario and Quebec waterways, offers many safety and operational advantages: it is ultra-low maintenance, naturally resistant to insects, moisture and rot, has proven fire resistance qualities, and is sun and water repellent. At end of life, the siding can be disposed of safely, without environmental damage.

Net Zero Conversion

Highly efficient M&E systems provide for future Net Zero conversion. The Fire Hall is designed to accommodate a 40kW Solar PV system to offset and displace energy usage.

Site Challenges

The Fire Hall was built adjacent to an existing EMS Station and shares the road entrance and utilities. This presented a challenge in planning for construction, service entrances and operations. The team had to ensure that the Fire Hall does not impede EMS' emergency response process.
