Translink

Commercial Broadway Station

Angus Lighting was engaged to provide lighting design for the new station platform at Translink's busiest station.

The Commercial Broadway Station connects the elevated Expo Line, the Millennium Line, and the 99B Rapid Busway, handling an estimated 200,000 SkyTrain and bus passengers daily.

Concourse level lighting was installed on open, angled overhead trusses and provides indirect light to prevent glare and to deliver a soft, uniform and safe environment for passengers. The station area located on the level directly below the new platform saw an LED retrofit to suit that environment.

Some of the platform stairways feature lit handrails as an architectural element to provide proper illumination of the stair treads. Lighting for the stairs and escalators was positioned for ease of maintenance, with the goal of avoiding having to install scaffolding whenever maintenance work was required for the lights.  

The new platform allows for passenger boarding from both sides of the train, a development that relieves congestion at this transit hub.

Designing for Safety

The new lighting consists of all LED luminaires, including dedicated platform edge lighting, with special optics to focus passenger attention clearly on the platform edge for enhanced safety.

Architecture and lighting

To illuminate the rest of the platform, the architectural steel ‘trees’ housed all the luminaires, and provided both provide direct and indirect lighting.

Easier Access Program - Subway Station Upgrades

The TTC’s ongoing Easier Access (EA) Program is making public transit more accessible for customers. The entire subway train fleet is accessible, and more than half of Toronto’s subway stations are wheelchair and scooter friendly.  

HH Angus has been providing vertical transportation consulting and mechanical and electrical engineering to the TTC since 2010, as the transit system implements EA accessibility upgrades. This involves the design and construction of new elevator systems, as well as changes to the electrical and mechanical systems needed to accommodate the addition of  EA upgrades across the subway system.

At the Wellesley Station, for example, two new elevators have been added. The work to support this upgrade included hydraulic, electrical, mechanical, structural and architectural components, along with the detailed project coordination aspects related to renovations.

Some of the challenges associated with the EA renovations include emphasis on limiting space requirements for new subsoil structures, reduced encroachment on property lines, reduced access limits for new equipment installations, relocation of existing services, and routing of new services through very confined and limited space, all requiring very specific, detailed and well-coordinated design.

Detailed coordination between all disciplines regarding all aspects of the project must be part of the design phase to minimize the potential for contractor-claimed extras during construction. For example, quick turnaround times for construction support activities must be adhered to, in order to achieve the construction schedule.

Some of the key success factors in EA upgrade projects include:

- Thorough site investigations prior to design to confirm all as built information. This is critical to determining where new services will be located and connected to existing services, in order to avoid any interference with those services, and to identify where relocation of existing equipment may be required.
- Close coordination between all disciplines to ensure a) the responsibilities of all project team members are clearly defined, and b) that the design is fully buildable without additional unknown factors; for example, avoiding issues that can arise from incomplete or outdated as built drawings.
-Having all stakeholders review the design, with all comments being addressed prior to Issued for Bid stages.

Over twenty subway stations are already complete or currently have upgrades in design or construction:

Union | St. George | Pioneer Village | Kennedy | St. Clair West | Queen | Bay | Ossington | Lansdowne | Museum | Lawrence | Yorkdale | Yonge/Bloor | Finch West | Kipling | Warden | Bathurst | Jane | Sherbourne | Wellesley | Christie | Keele | Rosedale | Chester

Space constraints

Because space for EA projects is very limited and within a confined area, all construction details must be effectively designed to ensure constructability.

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) is 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 is being undertaken as a P3 project. HH Angus is providing mechanical design, vertical transportation design, and commissioning of all systems serving the airside and the PTB. We are working with a local affiliate to deliver contract administration services during construction.

The vertical transportation scope for the project includes five new machine-room-less (MRL) traction passenger elevators and four escalators.

Some of the interesting challenges of the project include 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 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.

Environmental Requirements Create Savings

Among the features of the engineering design, the high water table easily allows for geo-thermal heat rejection for the cooling plant. And the building code on rainwater reuse is a built-in ‘green’ feature.

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.
