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.

Porter Aviation Holdings
Ottawa Airport Hangars
Porter Aviation Holdings Inc. has built two massive aircraft hangars at the Ottawa International Airport. At 150,000+ square feet and $65 million, the project was designed by Scott Associates Architects. PCL served as construction manager together with Span Construction & Engineering. HH Angus provided mechanical and electrical engineering to the project, as well as ICAT and security design.
The Porter hangars were constructed in two phases - the first was completed in late 2023, and the second in 2024 Q1. The complex is part of a series of projects to revitalize the Ottawa Airport to accommodate increased air travel demand in the National Capital Region, and will serve as a primary maintenance base, with 200 local hires, including 160 aircraft maintenance engineers, shop technicians and administrative support staff.
The hangars span approximately 86 metres, and house up to eight aircraft, along with various repair and parts modification shops.
One of the project’s key design criteria was to exceed current energy efficiency standards, in line with the airport’s commitment to net-zero operations by 2040 or sooner. The hangars were designed with sustainability in mind; for example, some of the important features include:
- A predominantly electric fleet of vehicles for towing and servicing aircraft, as well as ground support
- Design criteria exceeding current energy efficiency standards
- Constructed with approximately 35% recycled steel that can be recycled at the facility’s end of life
- Constructed from materials with 28% lower embodied carbon than conventional tilt-up assemblies
- City fire hydrant system is fully supplemented by an onsite underground water storage tank capturing approximately 1.2 million litres of excess rain/stormwater to avoid overstressing existing city mains.
HH Angus is also working with Scott Associates Architects on Porter Aviation's Saint-Hubert Airport Terminal project, a new zero-carbon terminal that will serve an estimated four million passengers annually. We were also involved with the original revitalization of the Billy Bishop Toronto City Airport that was completed in 2011, as well as its further expansion in 2014, and have been working with Porter Aviation since its inception.

Oakridge Centre
Redevelopment
Vancouver's Oakridge Centre is a visionary mixed-use redevelopment of approximately 4.3 million square feet, plus residential areas. The work will be completed in two phases and will encompass a vibrant mix of retail, office, residential, cultural, and civic spaces, along with a landscaped rooftop park.
HH Angus provided fire protection Engineer of Record design services for approximately 2.5 million ft2 of the retail, parkade and service areas, as well as peer review of the central plant engineering.
An interesting aspect of our project scope is the multiple water parcels and phasing, which meant needing to design each section with expansion in mind. Our project design work is being completed entirely in Revit, with a program called Autosprink that allows us to place the sprinkler heads and then connect them to provide highly-detailed hydraulic calculations. This involves laying out heads, branches and mains, and performing all calculations to present for sprinkler permits. The design also includes multiple fire pumps and a back-up cistern to store water on-site for use in the event of waterflow emergency.
The project requires a strong focus on effective communication. Our team's seamless collaboration with multiple partners and consultants through open and inclusive communication channels encouraged the flow of information and ideas, fostering creative problem-solving and innovative solutions. These often required coming up with alternative code-compliant solutions.
Despite only joining the project during design development, we successfully applied cutting-edge software and project management techniques to deliver our assigned scope within the designated time frame. As a result, we have been awarded additional project scope and the opportunity to further contribute to the overall success of the project.

Mount Sinai Hospital
Phase 3A Redevelopment
Phase 3A represented the largest redevelopment in Mount Sinai's history. HH Angus was engaged to provide mechanical and electrical engineering for the Renew Sinai redevelopment.
HH Angus worked with the Hospital, Stantec Architecture and other consultants to develop the Functional Program and Blocks Schematics for Ministry of Health and Long-term Care [MOHLTC) stages 2 and 3.1 submissions.
As part of our scope, we were involved in the investigation of existing infrastructure and systems. The age of the existing facility, together with previous renovations and multiple facility architects and consultants provided a challenge in obtaining a complete set of existing design conditions. We were provided with drawings in various forms (eg: PDFs. scanned hand-drawn images, AutoCAD and part plans), ranging from the original build to the most current renovation projects. We translated the relevant information into AutoCAD and, in with numerous site investigations, assembled a comprehensive set of record drawings detailing the existing systems and functions.
The scope of the project included a new Surgery Department, renovated and expanded Emergency Department, Critical Care, Medical Device Reprocessing Department, Integrated Practice Unit, Ambulatory, and labs, as well as miscellaneous relocates and decants.
Some of the key challenges of this project included reworking the major mechanical and electrical infrastructure to upgrade systems to current standards, and the integration of disparate systems with existing facilities.
Extensive renovations were implemented. To address the challenges of implementing new infrastructure, HH Angus provided extensive background information and on-site investigation to mitigate risks to the Hospital.
Minimizing disruption to hospital services was of paramount concern in scheduling the renovations. To ensure continued hospital operations, our design solution included planned sequential shutdowns minimized inconvenience to staff, patients and visitors.
Under a standing offer with Mount Sinai, we served as Mechanical and Electrical Engineers of Record and were involved in a variety of projects for Phase 3, including: peer review, fluoroscopy unit. Maternity Clinic renovation, Mouse MRI Lab, Biorepository Lab, Roth Lab, Bremner Lab, Distributed Antenna Systems, lobby upgrade, art gallery/ security/office renovations, and IMIT Planning for Phase 3 Redevelopment and renovations to multiple departments.
