Halton Healthcare
Oakville Trafalgar Memorial Hospital
As a large super hospital, this greenfield ~ 1.5 million ft2 facility features ORs, Emergency Department, Diagnostic Imaging, Mental Health, Long term Critical Care, and Dialysis services. There is also a large central kitchen and central Sterile Processing department. The hospital has been certified LEED Gold NC, exceeding its target of LEED Silver NC.
The central utility plant provides 4200 tons of cooling, 1500 bhp of hot water and 1500 bhp of steam. There is 15 MW of generator capacity onsite, along with 72 hours of fuel oil storage and a large fuel oil distribution system.
Some of the complexity inherent in this project was due to the design work being split between multiple engineering companies, which significantly increased the amount of coordination required. A key challenge was simply the scale of the new hospital, which increased the complexity of all of the systems. It required integration of systems across multiple engineering companies who were producing different portions of the design.
Another challenge was the extremely tight project schedule. This meant that tasks, which are normally completed sequentially, had to be done concurrently. This required very exacting planning and accelerated design work. Regular meetings with multiple engineering and architecture disciplines allow parties to bring their issues and design requirements to the table and to work through them in a collaborative way.
The vertical transportation design scope included 33 elevators servicing the main hospital building and 3 providing service to the parking garage.
The project co. required commissioning support for the contracting team in order to achieve milestones. HH Angus assembled a separate team of technical personnel to blitz specific systems in a 7-week period. With little preparation time, HH Angus leveraged members of the design team to train the commissioning personnel prior to going to site.

Trillium Health Partners
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.
