Toronto Transit Commission

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.

Preliminary Design


Halton Healthcare

Oakville Trafalgar Memorial Hospital

As a large super hospital, this greenfield ~ 1.5 million ft2 facility features ORs, Emergency Department, Diagnostic Imaging, Mental Health, Long term Critical Care, and Dialysis services. There is also a large central kitchen and central Sterile Processing department. The hospital has been certified LEED Gold NC, exceeding its target of LEED Silver NC.

The central utility plant provides 4200 tons of cooling, 1500 bhp of hot water and 1500 bhp of steam. There is 15 MW of generator capacity onsite, along with 72 hours of fuel oil storage and a large fuel oil distribution system.

Some of the complexity inherent in this project was due to the design work being split between multiple engineering companies, which significantly increased the amount of coordination required. A key challenge was simply the scale of the new hospital, which increased the complexity of all of the systems. It required integration of systems across multiple engineering companies who were producing different portions of the design.

Another challenge was the extremely tight project schedule. This meant that tasks, which are normally completed sequentially, had to be done concurrently. This required very exacting planning and accelerated design work. Regular meetings with multiple engineering and architecture disciplines allow parties to bring their issues and design requirements to the table and to work through them in a collaborative way.

The vertical transportation design scope included 33 elevators servicing the main hospital building and 3 providing service to the parking garage.

The project co. required commissioning support for the contracting team in order to achieve milestones. HH Angus assembled a separate team of technical personnel to blitz specific systems in a 7-week period. With little preparation time, HH Angus leveraged members of the design team to train the commissioning personnel prior to going to site.

Alternate approach to Cx

Through a cycle of improvements in methodology, HH Angus was able to improve productivity on site by more than 100% with an alternate approach to commissioning, which was shared with other onsite commissioning groups.

SickKids

Peter Gilgan Centre for Research & Learning

“This investment in the Research and Learning Tower will help ensure that Canada remains a world leader in health research, and that we will continue to make discoveries that benefit children around the world.”

– Gary Goodyear, Minister of State for Science and Technology

HH Angus provided mechanical and electrical consulting engineering for this 740,000 ft2 high-rise research and educational facility. This building enhanced the overall campus of SickKids, which totals over 2,500,000 ft2. SickKids is a landmark hospital and renowned internationally as a world-class institution.

The facility has been certified LEED® Gold. Energy modeling indicated a significant improvement over the minimum energy performance required by the program. Systems were segregated to achieve significant thermal reuse within the facility. The option to integrate a waste heat recovery system from the neighbouring district heating provider was incorporated into the design to realize even greater energy efficiency in future.

The building services design supported the main objectives for the new facility:

  • Consolidate the Research Institute into a cohesive unit
  • Integrate research functions with the hospital
  • Provide flexibility for future change
  • Maximize functionality and efficiency
  • Share support functions
  • Utilize current technologies and infrastructure, including a plan for increased security for highly specialized spaces such as Containment Level 3
  • Incorporate exemplary sustainable “Green” building design concepts and system
  • Create a high-tech, cost-effective space for evolving state-of-the-art technologies

The interesting design challenges inherent in this high-rise lab building contributed to both the complexity and enjoyment of the design process, including a 1½ storey vivarium and 40,000 ft2 of educational space.

General Electric

Brilliant Factory

General Electric’s new state-of-the-art gas engine plant is one of the most advanced in GE’s global operations and the first of its kind in Canada.

“It’s a plant that is reimagining how we manufacture. It incorporates all the concepts of lean: speed with excellent quality — coupled with everything that is now available and that is coming down the pipe in digital technology, with the latest in software developments.”*

— Elyse Allan, GE Canada CEO

HH Angus provided mechanical, electrical, plumbing, security, IT, lighting and vertical transportation consulting. The multi-modal plant, now owned by Advent International, manufactures gas engines that are coupled with either air or gas compressors, or with electric generators. The engines are distributed worldwide, primarily outside North America, in the oil and gas industry.

The plant runs three-dimensional machining simulations for CNC programs, gains real-time analytics to better understand the operating conditions of a machine or a test cell, operates lights-out machining, and combines all with advanced lean manufacturing practices.

Our IMIT scope included flexible structured cabling systems and supporting infrastructure, consisting of the latest shielded copper and fiber technologies, providing a transport platform for data, voice, video and other IP-based systems.

We also provided design for all low voltage technology systems. The factory uses equipment and machines embedded with sensors and connected to the high availability Industrial Internet Protocol-based network. Equipment data is streamed over secure links to the cloud for analysis.

Extensive design and installation of multiple audiovisual systems facilitate collaboration between global sites. Plant cabling design was provided per the most recent Industrial Premises standard. Working closely with the client’s IT, Security and AV groups, network-based systems were designed to the latest technology.

Our Angus Connect team was also involved in determining the performance requirements of client systems, product selection, preparation of working drawings and specifications, tender preparation and response evaluation.

Custom HVAC control

The plant is fully air-conditioned to prevent ‘flash rust’, which can occur during machining of items such as crankshafts and connecting rods if humidity levels are not carefully controlled.

Industrial and support spaces

In addition to the main assembly and machine areas, three test cells, warehouse space, and paint areas, the plant also features front of house spaces such as offices, staff support, fitness centre, customer areas, hoteling for visiting customers and GE staff, conference rooms, etc.

Expanding our scope

HH Angus’ project scope was increased to include the physical design of a significant new Test Cell addition to the plant, and to ensure Canadian compliance. The three test cells are connected to the main plant for testing engines prior to delivery. We met an aggressive schedule to produce working drawings for tender.

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.
