City of Toronto
Nathan Phillips Square - Indian Residential School
The City of Toronto is revitalizing areas of its landmark Nathan Phillips Square at New City Hall. As part of the improvements, a new Teaching, Learning, Sharing, and Healing space is being designed and constructed to pay homage to Indian Residential School Survivors.
The project consists of upgrades to existing surfaces with all new landscaping, including a water feature, large sculpture and public building.
HH Angus’ scope features a full technical audit and inventory report to document all infrastructure and equipment impacted by the project; power supply for new landscape and other LED lighting fixtures; connection of new area drainage to existing storm systems in the parking level; mechanical and electrical services for new 450 ft2 teaching lodge and design of security systems for public spaces and the teaching lodge.
HH Angus is also developing and preparing a commissioning plan for all mechanical and electrical equipment being installed during the project.
One of the interesting challenges of this project is working with multiple stakeholders to ensure the vision of all parties for the project is realized.

St. Michael's HospitalWalter and Maria Schroeder Brain and Heart Centre
“The catheterization lab's capacity is unparalleled and will enable us to make use of state-of-the-art equipment to care for our patients.”
Kim Boswell, Clinical Leader Manager Cardiac Catheterization Labs and Cardiac Arrhythmia Service, SMH
With the Walter and Maria Schroeder Brain & Heart Centre, St. Michael’s Hospital is creating a hub to bring together the world’s best brain and heart specialists, a group of multi-disciplinary experts in engineering and the clinical neurosciences, to develop new therapies for brain-related disorders, such as Alzheimer’s, Lou Gehrig disease (ALS) and Parkinson’s. The new centre will enable patients to be diagnosed, tested and treated in a seamless approach in a single location.
The new catheterization lab, where diagnostic imaging procedures take place to diagnose and treat cardiac issues, is now the largest of its kind inside St. Michael’s, expanding by almost a third of its previous size. The new robotic C-arm will set new benchmarks for precision during various diagnostic imaging procedures.
HH Angus was engaged to provide mechanical and engineering services; lighting design; IT, security, audio visual and communications consulting; and commissioning. Our project scope covered the renovation of an existing Cath Lab, along with associated equipment and control rooms, in order to accommodate a larger footprint and new state-of-the-art medical and imaging equipment.
The project design was future proofed with the expanded Cath lab providing increased capacity for cardiac procedures, thanks to a requirement to design the procedure area to be flexible enough for use as an Operating Room in future. It also includes state-of-the-art audio visual capabilities, with live data streams displayed on electronic screens throughout the room. Future capabilities include extensive video and audio feeds from within the room, as well as the ability to videoconference and live-stream procedures to locations both within and outside St. Michael’s. This will facilitate education, research and external consults.
Upgrades included: medical gas system and alarm replacement, including the installation of an articulated service boom; eventual conversion from passive to active scavenging system; ventilation system; and two new neuro interventional bi-plane suites, enabling image-guided and minimally-invasive procedures.
Challenges met by our project team include:
- Designing the space to meet a Hybrid OR environment, including supplying 20 air changes per hour above the patient care area with limited ceiling space
- Creating flexible ventilation design to allow future connection to a new air handling system, without causing major shutdowns to or rework of the existing space
- As a partial solution to #1, installing a combined lighting and air supply product (EH Price Ultrasuite), which had not yet been implemented anywhere in Canada, and ensuring all local code requirements were met.
- Coordinating the complex video requirements of multiple specialized medical systems in order to route diagnostic-quality video and audio feeds appropriately.

Bermuda International Airport
Redevelopment and New Terminal
The L.F. Wade International airport is the world’s gateway to Bermuda, and the redevelopment of its existing Passenger Terminal Building (PTB) is a high priority for the small island country. Because the current terminal is prone to flooding, it is susceptible to damage from major Atlantic storms, which could seriously impact Bermuda’s vital tourism industry.
The PTB redevelopment is being undertaken as a P3 project. HH Angus is providing mechanical design, vertical transportation design, and commissioning of all systems serving the airside and the PTB. We are working with a local affiliate to deliver contract administration services during construction.
The vertical transportation scope for the project includes five new machine-room-less (MRL) traction passenger elevators and four escalators.
Some of the interesting challenges of the project include its profile as an international project on an island; adapting to local authorities having jurisdiction; resistance to hurricanes; flood mitigation; and the island’s water strategy–Bermuda requires that all rainwater be captured and re-used, and the new PTB represents the largest roof area in the country. Also, salt-laden air and accelerated corrosion require the use of non-traditional materials as compared, for example, to similar buildings in Canada.

Size: 2,886,902 ft2 (26,820 m2) | Status: Completion 2020
KEY SCOPE ELEMENTS
Five new machine-room-less (MRL) traction passenger elevators and four escalators | Innovative mechanical design | Geothermal heat rejection for cooling plant | Mandated rainwater reuse for largest roof area in the country
Environmental Requirements Create Savings
Among the features of the engineering design, the high water table easily allows for geo-thermal heat rejection for the cooling plant. And the building code on rainwater reuse is a built-in ‘green’ feature.

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.
