Eglinton Crosstown Light Rail Transit
This project is the largest transit expansion in Toronto’s history, and one of the largest P3 projects in North America. When complete, it will move people 60% faster than existing bus service and will accommodate ten times as many passengers.
The new light rail transit line runs along Eglinton Avenue between Mount Dennis Station (Weston Road) in the west and Kennedy Station in the east. The 19-kilometre corridor includes a 10-kilometre underground portion between Keele Street and Laird Drive. The line features 25 stations and stops, with links to bus routes, 3 subway stations and various GO Transit lines. HH Angus is providing mechanical and electrical consulting engineering for three stations – Mt. Pleasant, Leaside (Bayview) and Laird.
HH Angus’ mechanical scope includes ventilation and air conditioning of services spaces, sanitary and storm drainage throughout the station, track level and specialty trackwork drainage, fire protection systems for retail and service areas, water efficient plumbing fixtures and energy efficient HVAC systems.
Electrical scope covers power distribution, lighting and communications systems. Design layouts are provided for power distribution of the subway station, as well as traction power for the trains.
The lighting design features reduced power consumption. Exterior public areas lighting designs incorporate increased daylight levels, LED lighting in pylon signs, and energy efficient lighting in illuminated wayfinding signage to minimize power consumption.
Communications systems design includes fire alarm protection, public address speakers, passenger intercom, TTC pax telephones, public telephones and security systems including closed circuit television.

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) was 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 was undertaken as a P3 project. HH Angus provided mechanical engineering and vertical transportation design for all systems serving the airside and the PTB, working with a local affiliate to deliver contract administration services during construction.
The vertical transportation scope for the project included five new machine-room-less (MRL) traction passenger elevators and four escalators.
Some of the interesting challenges of the project included 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's building code 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.
Among the features of the engineering design, the high water table easily allowed for geo-thermal heat rejection for the cooling plant.

Fraser Health Authority
Royal Columbian Hospital Redevelopment
The Royal Columbian Hospital is the oldest hospital in the province of B.C. and one of the busiest in the Fraser Health Authority. Royal Columbian provides expert care to the province's most seriously ill or injured. It is the only hospital in B.C. that caters to trauma, cardiac care, neurosurgery, high-risk, obstetrics, neonatal intensive care, and acute mental health care all on one site.
HH Angus and Associates is serving as the Planning, Implementation and Closeout Consultant for the Fraser Health Authority’s large, multi-phase redevelopment for Royal Columbian Hospital (RCH) in New Westminster, BC.
RCH is British Columbia’s oldest hospital, and one of only two adult trauma centres in the Lower Mainland. The plan, rolling out in three proposed phases over a decade, will see a major expansion of the acute care campus, with upgrades to critical infrastructure.
Phase 1 included a number of projects to help prepare the hospital’s infrastructure for future expansion. These were a new energy centre; a five-storey, 75-bed mental health and substance abuse facility; underground parking for 450 cars; and a regional data centre which will serve all Fraser Health sites, including 12 hospitals and a large group of community healthcare centres serving a population of 1.6 million.
Phase 1 design challenges included the site itself, which is a steeply sloped, truncated triangle constrained on four sides by roadways. Working closely with CannonDesign, we developed an Indicative Design to ensure the site would work for a mental health building while accommodating the energy centre.
Other challenges included complex scheduling issues to maintain reliable services to the site as the new Energy Centre replaced the old one, and the design of a new, large heating, cooling and electrical plant to serve the current and future RCH campus. HH Angus engineers drew on their deep experience in delivering large healthcare projects to project the future heating, cooling and electrical demands on the Energy Centre that would support the long-term needs of RCH for buildings not yet designed.
Phase 2’s new Acute Care Tower will house a number of services, including emergency, surgery, intensive care and inpatient rooms. Expansion and renovations to the existing buildings will follow in Phase 3. New buildings will be designed to LEED Gold green building standards, and incorporate BC wood, as part of Fraser Health's and the Province's commitment to sustainability.

Ricarda’s Restaurant
The heritage building at 134 Peter Street is a four-storey brick and beam former bakery that was incorporated into a modern office tower. The tower garnered a great deal of attention when it opened for its use of a delta frame and tubular columns to stabilize the office tower.
Ricarda’s is 10,000 ft2 restaurant/retail bakery site located within the heritage portion of the building, and was a very complex project. It presented a number of constraints that challenged the M&E design team to find workable solutions on a very aggressive construction schedule.
Because the original building is governed by the Heritage Act, this added a layer of complexity in terms of specifying equipment compliant with the Act. The entire project team worked hard to find creative solutions that would allow them to deliver a very challenging project on time and on budget.

KEY SCOPE ELEMENTS
Mechanical design developed to suit open ceiling concept within heritage portion of building | Incorporated a fire protection system | Lighting Design
Redefining Space
Another challenge was minimizing services along the ceiling so that we could maintain the interior designer’s open ceiling concept. This was particularly difficult because, while the site is on the ground floor, it has no basement, just a five-foot-high crawlspace earmarked for storage. Our design team ran drains through this space and connected them to the main building drains. We then had to add sprinklers, as the area was now deemed habitable.
Negotiating New Uses
We also negotiated these unforeseen uses with the landlord and obtain design approval for the fire protection systems, since the crawlspace was never intended for these uses.
Respecting the Vision
To maintain the open ceiling aesthetic, we ran electrical conduits through the crawlspace to route power for kitchen equipment.
Award-winning Lighting Design
Our IES Award-winning lighting featured both eco-friendly luminaires and ongoing cost savings by reducing energy consumption.
Adjacencies of mixed-use spaces challenged our design team to deliver the appropriate LED lighting solutions for dining, retail, reception, lounge and kitchen zones.

Downtown Relief Line South (Ontario Line)
“The proposed Relief Line South, a 7.5km long planned subway line with 8 stations, was intended to connect the Yonge-University-Spadina Subway (Line 1) downtown to the Bloor-Danforth Subway (Line 2). The Relief Line South was conceived to relieve crowding on Line 1 south of Bloor, at the Bloor-Yonge Station, and on the surface transit routes coming in and out of downtown.”*
HH Angus was engaged to produce preliminary systems design for two subway stations on the line: Gerrard Station, an in-line station, and Pape, one of the interchange stations, in this case with the existing Bloor/Danforth Line.
Funding and plans for transit relief lines are under review.
