KEY SCOPE ELEMENTS
HVAC, plumbing and drainage systems | Vertical transportation design assistance for 7 East stations to allow convenient public access between platforms and concourse levels
Custom-designed elevators
Tight space conditions required that the elevator shaft sizes be optimized and the car shape be designed to accommodate both mobility assist devices and emergency response gurneys. Enclosed in a glass and structural steel shaft, the elevator cabs complement the station’s unique architectural design by maximizing the use of glass for both cabs and entrances.
The transparency offered by the design enhances the security of those using the elevators, while an array of operating features simplify both routine and emergency functions.
Dedicated public transit routes
Much of the BRT East route is located within the Parkway Belt West, a broad band of public property reserved for linear transportation facilities and utilities. The corridor is occupied by various underground and overhead utilities and crossed by several roads, with access road linkages to adjacent arterials.
York Region
Operations & Maintenance Bus Garage
The 230,000 ft2 Bus Garage in Vaughan, Ontario was retrofitted to accommodate the storage and maintenance of 230 York Region Transit (YRT) buses.
The facility was improved through a wide range of bus servicing equipment and building automation systems to minimize energy use and maximize operational efficiency. Both a new admin area and a training facility were included in the retrofit, which has been certified LEED® Silver.
The facility features state-of-the art ventilation and exhaust systems. There are two service lanes consisting of four indoor fuel pumps, vacuum stations, welding and body shop, paint booth, parts storage, tire bay, machine shop, two inspection pits, lubrication stations and two washers.
Our electrical scope included: normal and emergency power distribution design, fire alarm system design, telephone/data, communication conduit/raceway design, security system conduit/raceway design, system clock design, indoor lighting, and outdoor lighting design to meet LEED® Silver requirements.

KEY SCOPE ELEMENTS
Building automation and bus servicing equipment to improve operational efficiency | Normal and emergency power distribution | Energy-efficient system design to reduce water and energy demand | LEED Silver Certified
Energy efficient systems design
The building was designed to reduce energy and water demand. It includes a solar hot water system, and collection and storage of rainwater for washing buses and flushing toilets. The high efficiency HVAC system employs air-to-air heat exchange and is governed by a Building Automation System.
Best practices for environmental gains
Specifying for the light coloured roof helps reduce cooling demand in summer and mitigates the heat island effect. Interior materials and finishes were selected for the best possible indoor air quality. The construction waste diversion target was 95%. Best practices commissioning was used to ensure the building operates at optimal efficiency.
Halifax International Airport
Groudside Redevelopment Air Terminal Building
Vertical transportation systems within the Air Terminal Building (ATB) included two new scenic elevators, major alterations to a single administration elevator, and four new escalators. Two moving walks were provided to assist users in moving between the ATB and parking garage.
This development included renovations to the ATB along with a central elevated pedestrian bridge (ped-bridge) and node (ped-node) linking the Mezzanine Level with the adjacent parking garage. Escalators connect the three terminal levels, offering convenience for users.
Moving walks were installed within the 70-metre ped-bridge, with special attention paid to minimize the depth of the pit on the ATB side to ensure that height clearances for emergency vehicles on the road below would be maintained. HH Angus provided a full scope of services commencing with schematic design through to acceptance inspections of all elevating devices.

KEY SCOPE ELEMENTS
Vertical transportation systems within the ATB | 2 new scenic elevators | Major alterations to a single administration elevator and added 4 new escalators | 2 moving walks within the pedestrian bridge
Framing the view
As the new scenic elevators are a focal point, special attention was given to the design of the cabs and hoistway enclosure to make these elements as transparent as possible and, at the same time, create an area of passenger interest.
Introducing new services
The moving walks were unique in that they represented the first two such units in the Maritimes.
Airport Development Corporation
Pearson International Airport - Terminal 3
When Terminal 3 opened in 1991, the 2.8 million ft2 complex was an innovative mixed-use facility consisting of a 24-gate airport terminal, a 500-room hotel, a 3,200-car parking garage and up to 450,000 ft2 of future office space.
The project design combined the priorities of passenger comfort with technical requirements, while emphasizing fiscal responsibility. The terminal has undergone several major renovations since then, resulting in significant expansions to the Central Processor and Pier C.
Vertical Transportation (VT)
The HH Angus VT group was involved from the Concept Design through to inspections, with full design responsibility for the transportation systems, which, at that time, included more than 90 elevating devices, (elevators, escalators and moving walkways).
Our design team’s responsibilities involved managing specification and bid assessment, up to and including final acceptance reviews. The development combined the latest technology with private enterprise economics, which, as it related to VT, translated into excellent standards of service. Later expansion of Pier C included the addition of five elevators, four escalators and six moving walks.
Expansions to the Central Processor included the addition of four elevators and four escalators in the East Processor Expansion, and three elevators, three escalators and two moving walks in the West Processor Expansion.
Within the East Processor expansion, a pedestrian tunnel to the parking garage was introduced to reduce curb traffic between the Terminal Building and parking garage. As a result of this tunnel connection, the three primary elevators on the Terminal side were designed to accommodate the anticipated number of peak hour passengers and associated baggage and carts.
Lighting
Angus Lighting worked in concert with the architectural team to develop lighting design concepts for this prestigious airport. The architectural design called for lighting that would bring excitement to each space, complement the architects’ ambitions and be economically viable.
Special attention was given to innovative lighting techniques with the various lamp sources needed to make the Grand Hall one of the focal points of the terminal.
The resulting design incorporated space, light, brightness, colour, scale and form, while consuming a mere 1.2 watts per square foot.
