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.

Erindale GO Station Parking Structure
The 6-level parking structure, on Rathburn Road West in Mississauga ON, provides 1,740 parking spaces for GO Transit patrons.
Engaged as the Vertical Transportation (VT) consultant on this project, a design-build led by Kenaidan Contracting, HH Angus was responsible for overseeing the team’s effort in the development of vertical transportation system requirements. These included design coordination, tender and eventual participation in shop drawing reviews, progress field reviews, and acceptance services, with support from other direct report team members. HH Angus coordinated all stages of the VT work to ensure appropriate quality control standards were maintained through all phases of the project, and identified related work requirements associated with the elevating devices, permitting coordination of these with the remaining Design Team disciplines.
Six machine room less (MRL) traction elevators were provided - four in the Parking Garage, and two additional units serving the elevated pedestrian bridge connection down to track level.

TranslinkCommercial 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.

Toronto Transit CommissionEasier 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

Status: Ongoing system-wide upgrades for subway stations to provide accessibility | Mechanical, electrical and lighting system renovations and upgrades to support vertical transportation installations
Greater Toronto, Ontario
KEY SCOPE ELEMENTS
Design Build | Work within confined and limited space | Rapid turnaround on construction activities support to achieve schedule
Because space for EA projects is very limited and within a confined area, all construction details must be effectively designed to ensure constructability.
