Toronto-York Spadina Subway Extension
Pioneer Village & Finch West Station

The TTC’s 8.6 km line opened to the public in December 2017. All six stations are fully accessible and Wi-Fi equipped. The line is comprised of both tunnel and cut-and-cover sections. HH Angus provided mechanical and electrical consulting engineering for the Pioneer Village and Finch West stations.  

Above ground, the new stations include a main entrance, secondary and automatic entrance and electrical substation.  Our mechanical scope included ventilation and air conditioning of services spaces, sanitary and storm drainage for washrooms and service area, track drainage, fire protection systems, as well as incorporation of system-wide tunnel ventilation. In addition, it incorporated water-efficient plumbing fixtures and energy efficient HVAC systems.

Our electrical scope covered power distribution, lighting and communications systems. Design layouts were provided for power distribution of the subway station, as well as traction power for the trains.

Custom transit lighting

The lighting design featured reduced power consumption. Lighting design for the exterior public zones incorporated increased daylight levels, LED lighting in pylon signs, and energy-efficient lighting in illuminated wayfinding signage.

Comprehensive communications design

The communications systems design included fire alarm protection, public address speakers, passenger intercom, TTC PAX telephones, public telephones and security systems, including closed circuit television.

Billy Bishop Toronto City Airport

Expanded Air Terminal Building 

When the new 150,000 ft2 terminal first opened to the public in 2010, the airline expected to almost double the number of passengers from the year before. Phase Two included 10 bridged aircraft gates and two additional passenger lounges. The terminal includes a mix of retail, food services, duty-free, car rentals and other amenities.

The large arrivals hall area, along with the increasing number of people using it, required a specialized heat recovery system. HH Angus designed a high efficiency enthalpy heat wheel system using outdoor air supply.

Among the benefits of this heat recovery system are reduced operating costs from recovering heat that would otherwise be lost by venting to the outside. In turn, this allows for a reduction in the size and capacity needed for the heating and cooling plant that serves the system.

An exterior sprinkler system for the apron area was included in our mechanical design. This system protects building occupants in the event of a jet fuel fire on the tarmac.

Some of the interesting design challenges on this project included the integration of the sanitary sewage system with the existing Terminal system. The Toronto Islands site has no gravity drainage and requires a pumping system for sanitary sewage. Also, the site is a live airport operation, which presented unique challenges regarding phasing of services.

Our elevator system designs responded to user needs for accessibility, safety, reliability and operational efficiency. Based on anticipated traffic numbers, plus luggage, a single large roped-hydraulic elevator (2,270 kgs) serves travelers in the corridor leading from the Ferry Building. Adjacent to this elevator, three reversible escalators serve the large numbers of passengers travelling without luggage, or with small carry-on baggage. These escalators are direction-based upon dynamic requirement.

The terminal’s airside area is separated into domestic and trans-border. Each has been fitted with a single, smaller roped-hydraulic passenger elevator (1590 kgs), and a single reversible escalator for passengers with carry-on bags only, again direction-based on dynamic requirement.

Bangalore (Kempegowda)

International Airport

The Bangalore (Kempegowda) International Airport airport expansion will increase the airport’s capacity to at least 65 million passengers per annum. Phase 1A of the new Terminal currently includes an estimated 46 elevators, 29 escalators, and 17 moving walks.

In addition to the new Terminal, a multi-level car park is being constructed to accommodate an estimated 2438 passenger vehicles after Phase 2. In addition to the vehicle stalls, there is capacity for an estimated 450 taxi’s after Phase 2. A Metro connection to the Terminal is also planned following Phase 2 expansion, for which elevating provisions are currently being made.

HH Angus’ client is Skidmore, Owings & Merrill LLP (SOM) from New York, with whom we worked previously on a joint-venture architectural team with Adamson Associates and Moshe Safdie on Terminal 1 at Toronto Pearson International Airport.

Yonge North Subway Extension

In a joint venture with IBI Architects and Lea Consulting, HH Angus was engaged to produce preliminary systems design for the Richmond Hill terminal station for the proposed extension to Richmond Hill Centre for Toronto’s Line 1 subway.

 

Funding and plans for Toronto transit relief lines are under review.

Union Station Revitalization

One goal of this revitalization project was to substantially improve public access throughout the almost century-old Union Station. To that end, numerous elevating devices were added to the site.

Union Station is Canada’s busiest rail passenger facility, handling as many as 65 million passengers annually. This number is expected to grow substantially in the future, along with expanded commuter rail and other services. To assist in improving public access, HH Angus served as the Vertical Transportation (VT) Consultants overseeing work associated with more than 30 elevators and 20 escalators that were installed at various stages of construction.

Six completely new basement traction freight elevators were installed, engineered to suit existing hoistways, which were retained from above the platform level. To meet the requirements for heritage-designated sites, new landing doors for these elevators were designed to mimic the original door panels.

Specific to GO Transit, seven new MRL (machine room-less) traction elevators were introduced, while two existing hydraulic elevators underwent major alterations, and three existing hydraulic elevators were decommissioned.

HH Angus’ scope of services extended from the Concept Design stage through to commissioning reviews performed during the Construction Administration phase.
