St. Joseph’s Health Centre

Mental Health Emergency Services Unit

We consulted with hospital clinical staff, the architect and best practices documentation in the field of Mental Health design in order to provide tamper-proof and anti-ligature versions of M&E devices and services in all patient rooms.

Our project scope was the complete redevelopment of the existing Mental Health Emergency Services Unit. This involved upgrading and modernizing the unit in order to support eight patient rooms, (the previous unit had only three patient rooms).

New, energy-efficient LED lighting fixtures, complete with dimming controls, replaced the old, inefficient fluorescent lighting fixtures. Remote patient room controls, located at the Nurses’ Station, allow clinical staff to control the electrical receptacle in each patient’s room, the smart glass on the room’s door/window, as well as the room’s lighting fixture, including remote-controlled dimming. A modern real-time locating system was also provided; it includes patient tracking, staff duress and patient wandering functionality. Note: This project was honoured with a 2020 Toronto IES Illumination Section Award

More than 30 IP-based security cameras were installed, including two cameras in each patient room. These are viewable from computers at the Nurses’ Station.

One of the challenges of the project was that the hospital did not have a viable existing IT room to house all the new voice/data infrastructure. As a result, we had to design a new IT room on the floor below the renovation area to support the new unit and future Emergency Department redevelopment. This was done during construction; therefore, the design and coordination were fast-tracked and subsequently completed successfully.

Also, remote patient room controls were not well defined throughout the design process. During construction, we had to quickly coordinate with several vendors, each with a proprietary system, in order to provide a solution that the contractor could execute.

Following the 2003 SARS outbreak, Public Health Ontario needed a site to bring together academic, clinical, public health and government experts on infection control and prevention. HH Angus was instrumental in providing a high quality, energy-saving workplace to meet LEED-CI Silver standards, key to highlighting PHO's commitment to sustainable practices.

A new 250kW natural gas-fired generator installed on the roof is the heart of the command centre. Its purpose is to exclusively back up the Electrical and Supplemental HVAC systems serving the command centre. As the area has unusual 416/240V service, special voltage requirements were engineered to facilitate both lighting and power equipment. Harmonic-type transformers provided clean, non-distorted power to two distribution panels, 80KVA UPS, receptacle, lighting panels and HVAC units. The 80KVA UPS unit provides 30 minutes of non-interrupted power to the command centre to allow the generator to start and reach full load capacity.

Since the original building did not meet LEED HVAC requirements, we provided detailed and well-thought-out designs to meet LEED criteria. High efficiency fixtures reduced the burden on city water supply and waste water systems. In addition, lighting was a major component for the LEED-CI Silver criteria, with glare and contrast ratio control, linear fluorescent direct/indirect lighting systems, LED downlights, and daylight harvesting.

Information technology infrastructure was key to the successful long-term functioning of this facility. The infrastructure included telecommunications rooms, conduits, cable support systems and structured cabling systems. The IT rooms house all of the building’s telecommunications fiber optics and copper backbone systems, horizontal cabling system and networking equipment, including telephone, data and video services. In the meeting spaces, the large display wall is intended for daily presentation requirements but, in the case of an emergency response scenario, the room will serve as a 24x7 mission critical war room.

Seneca College of Applied Arts and Technology

Garriock Hall Mechanical Retrofit

Located on the King City campus, Garriock Hall renovations are part of Seneca’s on-going expansion. The retrofitted heating system provides improved comfort for the campus’ 5,200 students.

HH Angus was engaged as prime consultant for a retrofit at one of the campus’ main academic buildings. Our scope included replacement and upgrade to:

Twelve fan coil units, complete with additional coil elements
Approximately 30 hot water cabinet unit heaters located throughout the building, along with additional Building Automation System (BAS) integration
Dual-duct terminal boxes for approximately 2/3’s of the building. The terminal boxes themselves were upgraded from pneumatically controlled to digital controlled complete with BAS integration.
Domestic hot water system
Pool heating system

The project used low temperature heating water from a ground-source heat pump system. This increased the physical size of the replacement heaters, which required accompanying structural and architectural modifications.

Domestic hot water preheat was implemented to take advantage of the low temperature heating water from the heat pump system, and was implemented as part of the domestic hot water system replacement and upgrade. The upgrades included a new high efficiency condensing water heater paired with a heating water to domestic water heat exchanger.

The pool heating system was not operational prior to the project. It was made functional and upgraded to take advantage of the low temperature heating water available from the heat pump system, by replacing the heat exchanger and adding additional controls.

Dual duct terminal boxes upgrades included replacing the terminal boxes to implement Variable Air Volume (VAV) control. In a few areas, existing single duct VAV terminal boxes were replaced with those equipped with reheat coils to facilitate occupant comfort.

The project timeline was aggressive, with engineering design starting late May 2019 and tendering in late August 2019. The project took advantage of the 2019 Christmas break to complete the majority of construction in order to minimize impacts to the occupants.

Canadian War Museum

The Canadian War Museum is a unique and historically important project, with a signature design appropriate to its purpose. Situated on Ottawa’s LeBreton Flats, on the bank of the Ottawa River, this world-class facility is a major attraction for Canadian and international visitors.

Inspired by countless acts of Canadian bravery in conflict zones around the world, Architect Raymond Moriyama created a design which blends seamlessly into the surrounding landscape. The building features a landscaped roof - low-maintenance, self-seeding, and fully accessible. The Memorial Hall is strategically located at the intersection of two axes. One aligns the Memorial with the Parliament Building’s Peace Tower, and the other is the solar azimuth at precisely 11:00 am on November 11 - Remembrance Day - when 11 precisely-oriented rods capture the sun’s rays at that poignant moment for Canadians, symbolizing spiritual rejuvenation and a new beginning.

The vertical transportation system includes five (5) passenger elevators and one (1) freight elevator to accommodate movement of large artifacts.

The elevator system design for this project required that special consideration be given to the site location and its geological characteristics. All elevators are of the “holeless” hydraulic type, with special design features to attain the travel distances required, within very tight overhead allowances.

The Canadian war museum is an affiliate of the Canadian Museum of Civilization and houses 440,000 ft2 of exhibit, archive and office space, as well as a 4,200 ft2 theatre.

Peel Regional Police

Headquarters Renovation

The renovation project customized this building for policing and admin functions. Originally, the building had been designed for pharmaceutical research labs and support spaces.

HH Angus was engaged to provide M&E and IMIT consulting engineering for the partial renovation of this existing Peel Regional Police facility. The building has a gross area of ~ 91,000 ft2, with the renovated area totaling ~ 70,000 ft2.

The project involved replacing two boilers and heat pumps, along with the installation of a new make-up air unit on the roof. These service the entire building’s hydronic heating, while the new make-up air unit serves the basement area. As well, part of the contract was to upgrade mechanical systems to suit new load, due to changes in office floor layout and function.

Among the challenges of the project was the requirement for multiple site surveys in order to confirm the existing equipment on site. The project was also completed under a very aggressive schedule in order to meet the targeted occupancy date.
