Waterfront East LRT - Union Station and Queens Quay Link
The existing streetcar service begins underground at Union Station, extends south under Bay Street towards Queens Quay Station, and continues west under Queens Quay before surfacing at the portal just west of Harbour Square. The expansion will include for a new portal on Queens Quay West, between Bay and Yonge Streets, to allow for service expansion eastward along the surface of Queens Quay West.
HH Angus was engaged to provide mechanical and electrical consulting services for Preliminary Design Engineering for the Waterfront East LRT project. The work includes a Baseline Design (~ 30% design completion), a Class 3 AACE Construction Cost Estimate, and Level 3 project delivery schedule. This is to accommodate the growth and future passenger volume as part of Toronto’s waterfront revitalization project for the expansion of the existing Union and Queens Quay LRT Stations, and a new running tunnel and portal.
The upgrade will expand on the single track Union Streetcar Loop with a split unloading and boarding platform to become a side-platform station, with each platform capable of accommodating two vehicles simultaneously. An additional by-pass track with special trackwork on the outside of the passenger boarding/unloading track will also be accommodated within the station.
The existing side platform at the Queens Quay station will also be upgraded to accommodate two vehicles simultaneously boarding/unloading at each platform. In addition, the station will provide access to the Jack Layton Ferry Terminal and Toronto’s downtown underground PATH network.
The tunnel ventilation solution—providing at-grade ventilation shafts within a land-locked congested downtown area—required a thorough understanding of various design criteria, as well as meticulous coordination with Architectural, Structural and Civil Utilities disciplines. The final design would entail further computational design analysis beyond the scope of this project in order to address a design variance.
For the overhead catenary system, the team drew on involvement with previous projects (where we were not the designer of said system) to adapt and provide a tailored solution for the unique project requirement of traction power delivery within stations, tunnels, portals, above-grade and transitions in between, working closely with Civil Trackway and Structural disciplines.

Lions Gate Hospital Power Plant
The new underground power plant at Lions Gate Hospital is a key piece of infrastructure to enable construction of a new acute care facility in North Vancouver.
The existing steam-only power plant at Lions Gate Hospital did not meet seismic requirements and was quite dated. HH Angus replaced the existing plant with a new buried installation that includes boilers, medical gas, plumbing and electrical equipment, as well as the routing of services through an existing tunnel system.
The new design for the underground plant is a hybrid of hot water and steam boilers; this design will help to reduce both energy use and greenhouse gas emissions. It’s an innovative design that recovers heat from the power plant via a heat pump system and rejects heat back into the reheat systems. An architectural feature boiler stack was included in the design.
The RFP originally required relocation of the bulk O2 system; however, following a number of design iterations, the result was the provision of an Oxygen Concentrator system instead.
Implementation of the Fraser Health Authority’s BIM standards was also required for the project. This is the first time these standards were applied at HH Angus, and the work helped to develop a baseline for future Fraser Health projects.
Among the challenges of the project:
– With limited knowledge of the existing site, it was necessary to obtain all background information within a short timeframe through access to existing drawings (dating back to 1960s) and performing multiple site reviews.
– To provide the best solution, HH Angus explored multiple options, above and beyond the requirements of the original RFP and, although the timeline for completion of design and implemention of new BIM standards was aggressive, all deliverables were met on time.

“The Garry Hurvitz Brain Sciences Centre will revolutionize the future of brain health like never before. It will be a global hub of innovation that will accelerate the discovery of the next generation of treatments, prevention and possible cures to the world’s most debilitating brain conditions.”*
HH Angus is providing mechanical and Electrical engineering for this 118,285 ft2, three-storey above-grade structure. The building will be constructed within a dense urban campus between existing building wings and will be connected to the main hospital circulation spine, with flexibility provided to accommodate future expansion.
Our project scope includes:
- Expansions to existing infrastructure, including a new 1600 ton centrifugal 4160 volt Chiller;
- A major modification to the Emergency Power System to provide emergency power to at least one chiller and the chilled water distribution system;
- New steam service and high voltage electrical services to the new building from the existing power plant
- A significant Information Technology service and distribution system, including fibre cable connections to the hospital’s existing Core Distribution Rooms, new network hub room components, including network switches and all on-floor cable/outlet systems
- Significant expansions to the existing Building Automation System, central electrical metering system, fire alarm system, security system, CCTV system, nurse call system and Code White systems.
The new building includes:
- Mechanical and electrical services in the basement designed to provide for the current construction, as well as a possible future four-storey addition
- Adult In-Patient Mental Health Unit and PICU Unit on the ground floor, both with access to outdoor courtyards
- Child & Youth Mental Health Unit
- Circadian Study Unit on 1st Floor
- Neuromodulation Treatment Unit, Enhanced Examination, Teaching and Research units on the 2nd Floor
The Sunnybrook M&E services tunnel is a complicated space. Because this is a new building on an existing site and represents a major expansion to the campus, connections to existing buildings with multiple M&E ties are required.
Among the interesting challenges of this project was obtaining the required mechanical and electrical services spaces. The larger they became, the more they impacted the functional programming and the project budget. Compromises were made regarding ceiling heights, and collaboration with facilities management staff helped in obtaining the space required.
As well, the main entrance “glass box” presented some unique mechanical design challenges. Ventilating a two-storey structure with no exposed services required innovative engineering, including ventilating from below.
In designing the building systems for this project, our team devoted special attention to providing a living space that offers an excellent therapeutic environment for the brain-injured patient while, at the same time, ensuring the safety of both patients and staff; in particular, preventing any opportunity for self-harm by patients.
Within HH Angus’ lighting scope, LED linear fixtures set the stage for modern lighting aesthetics used throughout the new, state-of-the-art centre, including corridors, inpatient bedrooms, the main triple height lobby, and the exterior soffits. The efficient LED non-glare, dimmable lighting will be connected to a centralized lighting control system. The provided lighting management software enables facility managers to monitor, maintain and control the entire networked lighting control system, including schedules and energy usage.
