Infrastructure Renewal
The infrastructure renewal work for Trillium Health Partners is focused on the Queensway Health Centre site, an acute care facility. Some of the funding comes from Ontario’s Healthcare Infrastructure Renewal Fund (HIRF), which supplements a hospital’s existing infrastructure renewal program and helps address renewal needs on a priority basis.
As prime consultant, HH Angus is implementing a series of mechanical and electrical infrastructure upgrades that include air handling units, Phase four of the electrical infrastructure renewal, as well as miscellaneous other projects. The scope of work includes the redesign of major mechanical and electrical infrastructure. Along the way, we are integrating newly designed systems into existing facilities, which presents some interesting challenges, given the age of the existing infrastructure.
A key consideration of the work is avoiding disruption to hospital services, and this is the paramount factor in scheduling. In order to ensure continued hospital operation, carefully planned sequential shutdowns minimize disruption to both staff and patients.

Centre hospitalier de l’Université de Montréal
(CHUM)
Designing the mechanical, electrical, and security systems for one of North America’s largest P3 acute-care hospitals required a comprehensive understanding of the crucial demands placed on a hospital’s electrical system; knowledge of the intent and intricacies of codes and standards; value-engineering approaches gleaned from alternate project delivery projects; and lessons learned from complex redevelopment projects.
The Centre hospitalier de l'Université de Montréal (translated as University of Montreal Health Centre, or CHUM) is a mega-hospital complex designed to replace three existing hospitals in Montreal. One of the largest P3 hospitals in North America, it occupies more than 2.5 city blocks with more than 334,000 m2 (3.5+ million ft2) of floor space.
The CHUM project has been honoured with ~30 awards, including Canada's top engineering award, the Schreyer Award 2018 for HH Angus, plus an ACEC Award of Excellence and three Illumination Engineering Society 2018 Awards for HH Angus’ lighting designs for the Passerelle Skybridge, the Steeple, and Interior Lighting.
The hospital complex consists of a main 20-storey acute care block, with five levels underground. The upper floors house 775 beds in single rooms, and the lower floors contain diagnostic and treatment functions, including a large emergency department, 39 operating rooms, 7 MRIs and a full cancer centre with 12 bunkers. Distinct blocks house ambulatory care clinics, office space and logistics. Our scope also included two large data centres.
The facility has been certified LEED® Silver. HH Angus responded to a number of restrictions and requirements in the RFP with alternative approaches that were subsequently implemented, benefitting the project in terms of better functional use of space, flexibility for the future, cost savings and significantly improved energy efficiency.

KEY SCOPE ELEMENTS
Mechanical, electrical and security system designs were provided to facilitate concurrent development | More than 50 Revit® models linked | Project included components that would help future modification of the facility | Certified LEED Silver
A proven P3 approach
HH Angus developed an approach to deliver consistency and standardization of mechanical and electrical products with multiple contracts and installation contractors. To facilitate the concurrent development of multiple parts of the project, more than 50 Revit models were linked. This allowed work to proceed on construction documents for the core and shell of the building (including services), while design development continued in the clinical areas of the building.
Experience creates long-term efficiency
The RFP mandated a number of restrictions on the ventilation system that would have required two full intermediate mechanical floors and would have severely compromised future flexibility. We worked with CHUM and the proponent team to develop an alternative approach from which numerous benefits resulted, including the ability to modify occupancy and enable future renovations, which allowed an extra clinical floor to be constructed under the zoning height restriction.
Delivering more value
The RFP required a distinct air handling unit for each functional department, as well as restrictions on unit size and floors served. HH Angus proposed the use of larger, 100 percent outdoor air units serving multiple floors. We proved the merits of this approach to CHUM from an infection control perspective.
Proving a better solution to save energy
The RFP did not allow the use of heat recovery wheels due to perceived infection control concerns. We used 20+ years of successful experience with heat wheels to prove the approach to the client and compliance team. The RFP was modified to allow the use of heat wheels, enabling a much more cost effective and energy efficient solution.
Saving the client money
The RFP mandated a standby air handling unit for each critical care space, which would have required much higher capital and operating costs over the life of the building. We recommended manifolding a number of air handling units together to share the redundant capacity. This approach considerably increased overall reliability of the systems while reducing operating costs.
Robust, reliable, cost-effective electrics
Similar components in the electrical infrastructure were procured in separate equipment tender packages to obtain best pricing directly from the corresponding vendors. The installation scope was divided into sectors within the building and awarded to separate electrical contractors. This “carving up” of the design scope into multiple tender packages required a high degree of coordination with the DBJV, and was effective in keeping this massive ongoing project on track with budget and schedule.
Multifunctional security system design
Our Angus Connect Division designed a fully convergent IP-based (Internet Protocol) security system and the supporting IT infrastructure required for a large-scale Cisco high availability, medical grade network. We designed an IP-based integrated multimedia security system that includes several thousand IP-based cameras, intelligent card readers, and other security devices located throughout the hospital complex. This system includes PoE (Power over Ethernet)-controlled architectural door hardware connected to Cisco’s high availability medical grade network.
Discrete segments of the security system are reserved for clinical observation, parking control, visitor management, patient wandering and duress applications. Multiple control facilities were provided across the hospital, using multicasting over VLAN, configured on Cisco LAN.
The security system was designed to support sophisticated client “use and workflow cases”, providing interoperability, SOA (Service Oriented Architecture) and SOI (Service Oriented Infrastructure).
Angus Connect integrated all aspects of the security systems into a seamless and efficient operation, leveraging the most current technology wherever possible to improve efficiency, reliability and safety, thus simplifying information flow and access to users.
Bruce County Long Term Care
Brucelea Haven | Gateway Haven
Established in 1898 as the “House of Refuge”, Brucelea Haven has been providing residential long term care (LTC) for seniors for more than a century. Built in 2003, both Brucelea and Gateway facilities operate as not-for-profits.
Brucelea Haven and Gateway Haven were constructed to replace separate, outdated existing LTC facilities. The 93,161 ft2 Brucelea Haven facility in Walkerton features 144 beds with two resident floors located over a partial lower floor that houses day facilities and support services. Gateway Haven in Wiarton provides the community with 100 beds over 67,062 ft2 on three resident floors, with a lower floor plan similar to Brucelea.
HVAC systems were a prime consideration in the design of the new facilities, due to the ongoing problems in the old structures. The mechanical design incorporates total enthalpy heat recovery wheels for ventailation for the resident wings. Boilers are high efficiency, feeding hot water to heating coils that provide local room control on a grouped basis.
Both projects qualified under the Federal Government CBIP program for using 25% less energy than a building meeting the National Energy Code.

Woodbine Entertainment Group
Woodbine Casino Expansion
Woodbine Entertainment Group (WEG) is a longstanding and valued client of HH Angus, dating back to the late 1980s. Through successful projects at Woodbine over the years, and the development of a strong relationship, we are privileged to serve as a trusted advisor.
Woodbine Racetrack is home to Ontario Lottery & Gaming’s (OLG) most successful revenue generating facility. One of the challenges in providing services for this site is the uncompromising need to keep all services fully operational at all times. The system must provide total redundancy for 24/7 operation of the slot floor area and associated support spaces. When required, we provide around-the-clock service to minimize disruptions.
WEG’s “1 West Expansion” saw a former storage space renovated to accommodate 1000 new gaming floor slot machines, complementing the 2000-slot installation we had previously designed during original base building and fit out. The expansion required all new mechanical and electrical (M&E) services.
The slots expansion included significant upgrades to the electrical service, which had to be brought a long distance from the main electrical room. The new distribution was sized to handle all the new games, audio/visual equipment, surveillance equipment, lighting and general power loads. We also upgraded the emergency power system and synchronized the generators while, at the same time, maintaining the same level of available emergency power.
Other major projects at Woodbine have included:
- On-track lighting for Thoroughbred and Standardbred racing
- Replacement of the steam boiler plant with three 5,000,000 BTU/h (input) high efficiency boilers and two 1,200,000 BTU/h (input) high efficiency boilers
- Base building improvements to escalator, kitchen, grandstands
- Responsible Gaming offices
- ‘Backstretch Barn’ renovations
- ‘Backstretch’ domestic water service
- Generator system upgrade

Integrating old and new buildings
Addressing major renovations and integrating new infrastructure with existing systems was a key challenge for the team. To address this, HH Angus provided detailed background information and on-site investigation to mitigate the risks to the Hospital.
IMIT challenges
This challenge extended to the IT systems, where the team had to integrate existing IT infrastructure with the new building. Extensive work was required to bring the Hospital’s aging IT infrastructure up to current standards, and to provide future flexibility. HH Angus designed a solution that would properly integrate and communicate with both new and existing systems.
Daylight harvesting
The Tower’s atrium, with 11 storeys of natural light, will feature retail space, a patient information centre, and the Admitting Department.
