Trillium Health Partners

Infrastructure Renewal

The infrastructure renewal work for Trillium Health Partners is focused on the Queensway Health Centre site, an acute care facility. Some of the funding comes from Ontario’s Healthcare Infrastructure Renewal Fund (HIRF), which supplements a hospital’s existing infrastructure renewal program and helps address renewal needs on a priority basis.

As prime consultant, HH Angus is implementing a series of mechanical and electrical infrastructure upgrades that include air handling units, Phase four of the electrical infrastructure renewal, as well as miscellaneous other projects. The scope of work includes the redesign of major mechanical and electrical infrastructure. Along the way, we are integrating newly designed systems into existing facilities, which presents some interesting challenges, given the age of the existing infrastructure.

A key consideration of the work is avoiding disruption to hospital services, and this is the paramount factor in scheduling. In order to ensure continued hospital operation, carefully planned sequential shutdowns minimize disruption to both staff and patients.

Joseph Brant Hospital

Communications & Automation Technology (ICAT) Vision, Planning, Procurement

The ICAT strategy at Joseph Brant Hospital focused on the interoperability of services between the existing facility and the new facility to allow for seamless delivery of care across the campus.

Our project scope was to develop Joseph Brant Hospital’s (JBH) ICAT vision, and to assist with planning, procurement and implementation of the ICAT strategy. This project was aligned with the P3 procurement project of a new patient tower and renovations to the existing facility, approximately 500,000 ft2. The ICAT strategy included existing and new hospital information technology, communications and automation systems, including the wired and wireless network, RTLS, nurse call, security, etc., as well as peripheral IT device planning.

Our team took the project's leadership through strategic visioning sessions. We facilitated user groups to understand the operations and create the functional requirements, which were translated into technical requirements for ICAT and used to inform and develop the Output Specifications and Technical Specifications.

The team coordinated various funding sources through an Order of Magnitude Cost Estimate exercise to prioritize the ICAT solutions with alignment to the strategic plan. By doing so, the hospital was able to strategically balance its future vision with the organization’s capabilities to roll out an Implementation Roadmap.

Leading change

One of the challenges of the project was for users to envision how emerging technologies would fit into their current workflows and processes. Our team used a Lean approach, walking through current state processes and challenging users to see best practices, and how ICAT systems would play a role in the future state.

Technology supports learning

As a future site for medical teaching, JBH is looking for opportunities to introduce technology to advance the education mandate. In addition, the hospital continues to look for ways to enable patient care beyond the walls of the facility, through use of the systems by remote staff or providing pre- and post-hospital support and services to patients.

Siemens Canada

Algonquin College Trigeneration Plant

HH Angus was retained to design a trigeneration plant for Ottawa’s Algonquin College. Our scope included review of Siemens’ PSUI application to IESO, and assisting with their application. Because the existing central utility plant (CUP) was not large enough to accommodate new plant systems, our team developed a pre-engineered building to be built adjacent to the existing CUP.

As Prime Consultant, HH Angus retained Milman and Associates to undertake the required structural engineering, including a roof design to accommodate the cooling towers, rad cooler and transformer. An additional mezzanine was added to house auxiliary equipment.

In order to maximize the usable heat during summer months, a 350 ton absorption chiller, using double effect flue gas and hot water, was detailed. The 2 MW reciprocating trigeneration plant features selective catalytic reduction units and a heat recovery boiler.

Some project challenges included:

  • Integrating and commissioning a trigeneration system into an operating facility
  • Noise constraints due to proximity of CUP to College operations
  • Space constraints due to pre-engineered building
  • Footprint was maxed out based on site restrictions; HH Angus had to take into account future co-gen, chiller and ancillaries
  • Ongoing upgrades in CUP heating and cooling, which HH Angus coordinated with another consultant
  • Operating flexibility required for both parallel and island operation
  • Solutions included: designed mezzanines in the existing CUP to house equipment and accommodate new, pre-engineered building for the second cogen and chiller; and rigorous scheduling coordination with Utility and College operations staff

Minimizing Disruption

All new equipment was connected to existing systems, with electrical connections restricted to well-planned shutdowns, resulting in minimal disruption to the ongoing operations of the campus.

Ericsson Canada

Global Information, Communications and Technology Centre

HH Angus served as Prime Consultant on Ericsson’s greenfield modular data centre testing facility in Montreal. This was one of three such sites for Ericsson oriented to telecommunications research and development; the first two in Sweden were operational in late 2014. 

As Prime Consultant, HH Angus engaged and oversaw the structural engineers, civil engineers and architect, as well as the noise, vibration and air quality consultants.

The Centre, in Vaudreuil-Dorion, was built with modularity and scalability in mind, and to serve as the global facilities’ data centre.

Situated close to the firm’s R & D Hubs, the new facility was intended to connect 24,000+ Ericsson engineers worldwide, provide greater efficiency in research and development, and allow customers to connect remotely for testing interoperability in real time - for trials, early access, and new business services.

The Quebec site totalled 40,000 m2, of which 20,000 m2 was built out. The project included a 3530 m2 administration and support building. The company estimated that the combination of architecture, design and location would result in a significant reduction of 40% in energy consumption. Heat recovery strategies were implemented, such as waste process heat used to warm the building. In addition, a rainwater harvesting system provided water for both irrigation and process cooling.

One of the key challenges met on this project was managing communications. Four nations were involved (Canada, Sweden, the United States and the United Kingdom), and the team was spread over seven time zones, from Phoenix to Stockholm. While English was the working language of the project team, subgroups within it were variously working in Swedish, French and English.

Enwave Energy Corporation

District Energy System Cogeneration Plant

District energy is a key component of Toronto’s climate action plan, to reduce emissions from buildings and help the City reach its greenhouse gas (GHG) reduction target of 80% by 2050. Buildings currently generate about half of the GHG emissions in Toronto. 

Enwave is the largest District Energy Systems in North America. The system has enough power to supply over 180 office buildings.

This project started in 1962 with an original feasibility study and culminated in the design and construction of a central plant and distribution system with an installed capacity of 800,000 lbs. of steam per hour.

The deep lake cooling system was added later, and makes use of the 40°F/4°C water in Lake Ontario. It has a total capacity of 75,000 tons of refrigeration, which is sufficient to air condition 3.2 million m2 / ~34 million ft2 offices.

Clients with whom we have worked on the Enwave District Energy System include:

  • Hudson Bay Company
  • Bank of Nova Scotia
  • Cadillac Fairview Toronto Dominion Tower Plaza
  • Royal Bank Plaza
  • Mt. Sinai Hospital
  • Toronto General Hospital
  • Women’s College Hospital
  • The Hospital for Sick Children
  • Li Ka Shing Knowledge Institute
  • St. Michael’s Hospital
