Toronto General Hospital Rapid Assessment Centre (RAC) Expansion
HH Angus was engaged to provide mechanical and electrical engineering, IMIT consulting, and lighting consulting services for this 20,000 ft2 phased renovation at Toronto General Hospital. The space now includes a Rapid Assessment Centre, Diagnostic Test Centre, and Admitting and Pre-Admission Clinics.

The emergency department (ED) was designed to serve ~ 20,000 patients annually but was receiving more than 55,000 patients To better manage these volumes, a dedicated Rapid Assessment Centre (RAC) was added so that ED staff can triage lower acuity patients to the new "fast track" area, enabling primary emergency areas to care for more complex patients. Our team worked in conjunction with the client and other consultants to perform a pre-tender constructability review. This review included potential approaches to minimize disruption outside areas of construction, identify potential installation challenges, and complete pre-demolition of the first phase of work to identify any unknown site conditions in advance of construction. Due to the age of the existing space, there was a high probability of building systems and equipment being beyond their service life, and a certainty that codes and standards relevant to the design of the new space had changed. To address this and mitigate any risks, HH Angus performed a pre-design review to identify any specific potential issues with the new space and recommend steps to further address the unknowns. Scanning and 3D captures were performed regularly throughout construction, using Matterport Pro 2 and a Theta V 360 Camera. This provided the client with regular site progress updates and, in future, will allow for dimensionally accurate references for locating MEP services behind walls and ceilings. It also allowed for a more focused presence on-site, as construction progress was made available remotely to a range of project stakeholders amid COVID-19 pandemic restrictions. The existing ventilation systems presented a significant gap for the project, as their capacity to support the new functions of the space was unknown. To address this, HH Angus investigated and presented several options for review, taking into consideration the client’s budget, schedule, and planned upgrades for existing infrastructure.

Lonsdale Energy Corporation
Heat Recovery Feasibility Study
HH Angus conducted a study to evaluate the feasibility of exhaust air heat recovery from the Global Relay (GR) data centre facility at 22 Gostick Place in North Vancouver, BC.
Some of the key aspects of the study included:
- The location and footprint of the heat recovery system components were studied within the context of considerable site constraints. The study evaluated the design, construction, and cost considerations for the implementation of the proposed heat recovery system.
- We investigated available heat pump technologies that would be appropriate for recovering waste heat and would satisfy the LEC DES requirements.
- The energy recovered would be used by a water source heat pump to provide hot water to the local LEC District Energy System (DES).
- A water source heat pump system was proposed as the best solution to provide the ability to recover heat from the building ventilation system. The new system would recover heat from the GR facility and would transfer this recovered heat via a hot water loop to the local LEC DES.
- Heat recovery is feasible for the facility and can provide up to 1,100 kW of heating capacity to the LEC DES.
- Constraints to the design of the heat recovery system were also identified, and included:
(i) the quantity of air exhausted from the facility is not fixed and ranges at each exhaust plenum on a seasonal basis and depending on outdoor air temperature – this impacts how much heat can be recovered at a given time;
(ii) the minimum and maximum exhaust air temperatures range from 30°C to 43°C (86°F to 110°F) - the temperature of the exhaust air will influence how much heat can be recovered from the exhaust air; and,
(iii) the cross-sectional area available for the heat recovery coil - the more cross-sectional area that is available for a given amount of heat transfer, the less deep the coil must be (and less airside pressure drop penalty is incurred).
The study concluded that a purpose-built containerized heat pump system would be the most suitable solution to meet the needs of the project. This new containerized structure would be conveniently located adjacent to the GR facility and would exhibit the same architectural character as the existing facility. The proposed heat pump system would include one heat pump unit (based on Emerson Heat Pumps) and four heat recovery water pumps. Control valves, piping accessories, ventilation, lighting, and system controls would all be included in the proposed pre-fabricated containerized enclosure.
Outdoor hydronic piping would connect the heat pump enclosure to the GR facility and the proposed hydronic heat recovery coil system. The heat recovery coil system would consist of four new heat recovery coils placed within the existing facility exhaust air plenums. The existing exhaust fan motors would have to be upgraded in order to address the additional pressure drop introduced by the new heat recovery coils. This fan motor upgrade would also trigger upgrades to the existing electrical infrastructure.

Collège Bois-de-Boulogne
Server Room Air Conditioning
Pavilion Saint-Paul
One of the challenges of this project was to replace the main and redundant cooling systems in the server room while maintaining operations and minimizing impact on the College.
HH Angus’ scope of work for this project included analyzing the mechanical and electrical infrastructure of the server room, and proposing permanent corrective solutions. It also included implementation of solutions to provide redundancy for the mechanical infrastructure to guarantee full operation of the servers in the event of a critical power emergency or failure of the server room's main cooling system.
In order to analyze the existing installations, we performed site visits and surveys, and interviewed technicians responsible for the server room to gather as much information as possible about the existing installation, including any ongoing issues. We also reviewed and analyzed plans for the existing installation and performed a condition assessment - chilled water and glycol piping, insulation, ventilation ducts, electrical systems serving the equipment, and control systems - and took measurements in the mechanical and server rooms to ensure the new equipment could be properly installed while still providing space for maintenance work.
Following our analysis, we produced a report outlining the scope of work to refurbish the server room's cooling systems (main and redundant systems), ensuring the installation complied with current codes and standards. We produced mechanical and electrical drawings and specifications, including proposed solutions and equipment selection, and consulted with vendors to identify optimal solutions to meet the client’s requirements. During the tender process, we reviewed bids submitted by the contractor and provided recommendations to the College.
The intention was to complete this work over the summer when classes were not in session. Due to COVID-related delays in production of the necessary equipment, the work could not be completed on the original schedule and had to be undertaken when students were back in class. We worked very closely with stakeholders to avoid disruption to the students, with some work being completed before and after class or on weekends.

WPP
Toronto Waterfront Campus
WPP Group's building is part of the largest urban revitalization project in North America, bringing together new businesses, restaurants, and transport connections.
Work Design Magazine March 28, 2023
This cutting-edge project on Toronto’s downtown waterfront represents an evolution in commercial office development and reinvents how employees work together in Toronto’s rapidly evolving creative and technology sectors. The new space merges a large number of WPP’s operating companies and 2,000 employees into the top seven floors of the Waterfront Innovation Centre at the city’s iconic ‘Sugar Beach’. HH Angus provided engineering consulting services for this 250,000 ft2 tenant fitout project. WPP is the anchor tenant for the Waterfront Innovation Centre.
The fitout included raised floors for underfloor HVAC systems and is targeting LEED Platinum certification. On each floor, the design features a café, hub and IT equipment room, with one single Main Communications Room.
The 8th floor has a custom production area with very specific acoustic requirements. Our mechanical team worked closely with the acoustical consultant to provide a design that meets the strict acoustic requirements for video and audio production and recording. This was achieved through careful placement of fan-powered boxes equipped with silencers. The production area includes multimedia studios, photo studios and a print lab. Lighting control for these rooms is enhanced with tunable lighting, allowing users to adjust the colour temperature in real time.
The 10th floor is the client-facing floor and includes meeting rooms with fully-integrated AV, smart lighting control, open ceiling design concept (industrial design), a large point-of-sale catering kitchen with back of house facilities and an outdoor terrace.
Our communications team designed several interconnecting fibre risers to provide the client with the most cost effective solution and full redundancy to meet their current and future needs, and to ensure the system will continue to operate in the event of external critical failures.

Porter Aviation Holdings
Montréal Saint-Hubert Airport Terminal
Porter Aviation Holdings Inc., in partnership with Montréal Saint-Hubert Airport, is developing a new, fully electrified terminal to serve 4 million+ passengers annually.
Terminal construction begins mid-2023, with completion scheduled for late 2024. The terminal is being designed by Scott Associates Architects Inc., with HH Angus providing mechanical and electrical engineering services for the 20,000 m2 (225,000 ft2) terminal building (YHU). All systems will be designed to fully operate on electric power.
Features of the new facility include:
- Modern design aesthetic, featuring natural light and high-quality materials
- 21,000 m2 (225,000 ft2)
- 9 bridged aircraft gates
- Lounge-style seating for all passengers
- Food and beverage concessions, and retail vendors
- A fully-electrified facility with all building systems to fully operate on electric power
- State-of-the-art passenger and baggage processing, and security installations
Porter will continue expanding its existing operations at the Trudeau Airport (YUL) in Montréal, while introducing a Canada-wide network at the YHU airport. The airline intends to connect YHU with both of its Toronto hubs - Billy Bishop Toronto City Airport (YTZ) and Toronto Pearson International Airport (YYZ). The new terminal will also be open to other airlines.
The YHU terminal development is modeled after the successful revitalization of the Billy Bishop Toronto City Airport that Porter has been a part of since 2006. After decades of declining passenger service at the island airport, Porter's commitment to YTZ was the catalyst for route developments and infrastructure investments that led to the airport serving nearly three million passengers annually, across more than 20 routes and producing $3 billion in annual economic impact. The YHU terminal will also provide faster passenger processing, resulting in travel time savings.
HH Angus is also working with Scott Associates Architects on Porter Aviation's two new massive aircraft hangars at the Ottawa Airport. Phase 1 was completed in late 2023 and Phase 2 is scheduled for completion in early 2024. They are part of a series of projects to revitalize the Ottawa Airport so that it can accommodate increased air travel demand in the National Capital Region. We were also involved with the original revitalization of the Billy Bishop Toronto City Airport, as well as its further expansion in 2014, and have been working with Porter Aviation since its inception.
