Tenant Office Fitout
HH Angus’ scope of work required that all design for this ultra modern Toronto office space and showroom target LEED®-CI Gold certification.
A key design challenge for our team was the client’s strong preference for clean ceilings. This meant the design had to minimize conduit runs, devices, etc. Underfloor systems were used in the engineering design to ensure the majority of the mechanical and electrical infrastructure was concealed. The mechanical distribution under the raised floor used Camino systems.

Site-specific design
Our design team was challenged in locating services and systems, given both raised floors and exposed ceilings. The ceilings featured suspended direct/indirect lighting throughout the space.
Statement lighting design
Speciality and decorative lighting played an important role in this project, from selection of fixtures and providing samples and budgets for client approval, to photometrics to meet showroom conditions.

All Seniors Care Living Centres
HH Angus is providing mechanical and electrical engineering and lighting design to greenfield sites in Kingston, Ontario. The seniors’ care facility feature 170 residential units, plus ground-floor amenities including pool, commercial kitchen, gym, and multi-use spaces.
HH Angus has both long standing and recent experience in the retirement and elder care sectors, including long-term care facilities, complex continuing care, dementia centres, seniors’ homes, hospices, and similar facilities that combine a healthcare setting with a residential component. Over the years, we have developed a sensitivity to the design nuances associated with these facilities.
Our scope includes complete design for the building systems, inclusive of generator site services within five feet of the building, plus complete plumbing and HVAC design.
The building has been classified B3 under the Ontario Building Code, an unusual ‘tall building’ designation for a building of this style and height. This OBC classification required additional ventilation options compared to those required for similar mid-rise apartment buildings.
Effective coordination between disciplines was paramount in order to achieve the high ceilings the client desired. We worked closely with the interior design team, structural engineers and architects in order to deliver this design feature for the client.

KEY SCOPE ELEMENTS
Designed multi-storey long term care residential facility | B3 ‘tall building’ OBC classification | 170 residential units | Introduced multiple options for mechanical system together with estimated ROI

Sharing Expertise with Clients
HH Angus provided multiple options for the mechanical system, together with the estimated ROI for each, to assist the client in selecting the most appropriate equipment for this application.
We are also working with All Seniors Care on their new facility in Hamilton, Ontario.

Data Centre Expansion
Data centres operate 24/7. This large Tier 3 facility expansion required defined levels of redundancy to ensure the most complete reliability possible.
Our mechanical and electrical design included a central cooling plant and emergency generation system to support the critical data floors. The development involved a two-phase ‘design and construct’ concept, which was incorporated into the base design and operating strategy. The project was executed on time and within budget.
Mechanical Design
The Phase 1 concept required 3 X 750 ton centrifugal chillers, electrically powered with variable frequency drives (VFD’s) and incorporating N+1 redundancy. The chilled water distribution system was based on a primary and secondary concept with a ring main for increased redundancy, which allowed for back feeding in the event of hardware failure. All pumps have VFD’s for slow start and energy efficiency. Transformers were used to step down from 600V to 460V to further increase reliability on the VFD’s. The condenser water system was based on induced draft with counter flow cooling towers with VFD’s on the fans and utilizing tower free cooling for energy efficiency.
The design of the cooling system provided for Phase 2 expansion and the ability to implement an additional 2250 tons of cooling through 3 X 750 ton chillers, with improved redundancy to (N+2). The mechanical piping and ventilation design was carried out using Bentleys Autoplant 3D software to ensure functionality of the equipment and piping layout design. The 3D modeling was used successfully by the Constructor and integrated into their BIM (Building Information Modeling) program.
Electrical Design
The electrical engineering design provided for a 50,000 ft2 raised floor computer area serviced by redundant feeds from the existing 27.6kV distribution to redundant 600V distribution systems. Four 2 MW parallel synchronized diesel generators with capacity to increase to six; two systems of four redundant 750 kVA UPS modules; and state-of-the-art life safety, alarm monitoring, and security systems.
Subsequent upgrades to the facility included installation of two 3000A Static switches to the two parallel redundant 750kVA UPS systems, configured to not only permit seamless transfer of critical loads between utility and emergency power in the event one UPS system fails, but also to permit seamless transfer to the surviving UPS system. HH Angus functioned as Prime Consultant and Electrical Engineer for a series of reports, studies, distribution upgrades and raised floor expansions at the site.
The Data Centre’s diesel generator system included three buried storage tanks, each with a capacity of 75,000 litres, a generator ventilation system and diesel exhaust for four 2MW generators.
ICT Scope
Our communications group was involved with multiple communications projects for the expansion, starting from the structured cabling system, DAS –Distributed Antenna System, and building systems LAN/WLAN design. We provided a detail compliance analysis of the new proposed sites with references to the TIA 942 Data Centre standard.
As a part of the DAS, we provided an unbiased, independent assessment of the current data centre cabling infrastructure performance, as well as design recommendations and specifications to eliminate both scheduled and unscheduled downtime. The assessment included a comprehensive computer room site inspection, determination of the full scope of the telecommunications needs, design of a suitable structured cabling system, and the creation of written reports, prints and specification documents.

Designing for Uptime
Reliability was improved with underground remote water storage to support a 24-hour cooling tower make up in the event of supply water failure.
Electrical reliability was achieved through the installation of 6 X 2 MW diesel generators (N+1 redundancy), and a fuel storage facility consisting of 3 X 75,000L underground tanks.
Scotiabank
Ecosystem Program
The Scotiabank Ecosystem Program represented a comprehensive one million ft2 ‘refresh’ for floors and offices in downtown Toronto. The most pressing challenge was the schedule, which was both complex and compressed; for example, drawings for three floors were delivered in only three to four weeks, a more typical timeframe for design of a single floor.
Another challenge was implementing a design standard for existing buildings and infrastructure that differed by location. Often, the only common elements were architectural treatment and power supply. While all the buildings complied with the standards template for audio visual and connectivity, each presented unique challenges that required custom deviations from the standard in order to successfully execute the retrofit. Existing spaces were fully demolished down to the floor plate. The grid remained, but all lighting was reworked to conform to the new design. This was the third stage of a three-stage refresh, with our team having previously delivered stages 1 and 2.
