Quinte Health

Prince Edward County Memorial Hospital Redevelopment

The new Prince Edward County Memorial Hospital (PECMH) will be a leading-edge healthcare facility designed to met the current and future capacity needs of its local communities.

HH Angus was engaged by Quinte Health to provide the new hospital with mechanical and electrical engineering services, lighting, audio-visual, and security systems design, as well as energy modeling and ICAT digital strategy.

The project includes the construction of a new hospital with improved equipment and facilities, including a 24-hour emergency department, acute inpatient unit, helipad, surgical suite, diagnostic imaging, laboratory, dialysis unit, and other specializations.

Significantly, the PECMH will be the first acute care hospital in North America with an all-mass timber structure. Unencapsulated mass timber is faster and more accurate in construction compared to steel and concrete and sequesters carbon better than any other structural material. Use of mass timber is estimated to be saving the project over 9 million kilograms of embodied carbon dioxide compared to a conventional steel and concrete structure. Other sustainable aspects of the new building include energy-efficient windows, selection of sustainable materials and use of natural light in the building’s atrium.

Our systems design included a hybrid plant comprising a geo-exchange heat pump, gas-fired heating, domestic hot water generation and humidification elements. A six pipe, 200-ton geo-exchange heat pump has been designed to allow simultaneous heating and cooling to maximize efficiency performance. The geothermal system is expected to provide 50 percent of the hospital’s cooling and 90 percent of its heating. The new building will feature a solar panel installation on the roof, which will lower electricity operating costs and avoid the use of 2,000 tons of carbon during the panels’ lifespan.

Our ICAT team assisted in the development of a Digital Strategy to support the project. This included a current state assessment, visioning, implementation roadmap creation, and budget cost estimate. The ICAT scope of work also included systems integration design involving development of a comprehensive integration use case list through user engagement sessions, as well as developing the construction documents, consisting of an integration matrix, integration concept model / diagram, and integration specification.

The project was featured in Canadian Architect Magazine in April 2025, and in a 1-minute YouTube video.

CN Tower

Lower Observation Level

The CN Tower's Lower Observation Level was completed and unveiled in January 2026, as part
of the attraction's 50th anniversary celebrations.
The refurbished area comprises 10,600 square feet, including both indoor and outdoor viewing areas, a
glass floor, stairwells, washrooms, and the SkyPod elevator lobby.

The project was designed to seamlessly extend the recently renovated Main Observation Level 3 aesthetic down to Outdoor Observation Level 2, creating a cohesive and elevated visitor experience.

This renovation marked the first major upgrade to Level 2 since the Tower opened in 1976. HH Angus provided comprehensive mechanical, electrical, lighting, and communications engineering services as part of the transformation.

Mechanical
Scope included the complete refurbishment of existing washrooms, the addition of a new fully accessible washroom, and modifications to the HVAC systems to accommodate the new slatted ceiling design and updated spatial configuration.

The Co-operators Calgary

Tenant Fitout

This project focused on a tenant renovation of two floors in The Co-operators' newly-acquired downtown Calgary office space, and comprised 40,000 square feet. The project has been certified WELL Gold.

Our approach included early coordination with the landlord to ensure handover conditions suited the client’s requirements, as well as close coordination with the construction manager in creating a pre-order due to a condensed construction schedule.

The construction schedule was a key challenge of the project along with the timing of tender. The completion date was an unmovable milestone as the client’s lease was expiring at their other location. At time of tender, product and material availability were fluctuating, which created uncertainty around delivery. To meet the deadline, our team was tasked to do everything possible to ensure the success of the project and keep the schedule on track.

To help ensure timely delivery, our team incorporated a pre-order package for the construction manager to tender, which allowed products to be reviewed and released ahead of the official tender. This effort was successful and was completed according to plan; however, some delivery delays were unavoidable, due to market conditions. To mitigate the impact, we were then tasked with contacting industry partners to help expedite deliveries. In addition, alternative temporary designs were implemented to ensure the move-in date could be met by planning the switchover date once the outstanding equipment arrived.

The Calgary office marks our fifth tenant improvement project for The Co-operators, following similar fitouts for their locations in Guelph ON and Regina SK, as well as pilot projects in Montreal QC and Burlington ON.

Porter Aviation Holdings

Ottawa Airport Hangars

Porter Aviation Holdings Inc. has built two massive aircraft hangars at the Ottawa International Airport. At 150,000+ square feet and $65 million, the project was designed by Scott Associates Architects. PCL served as construction manager together with Span Construction & Engineering. HH Angus provided mechanical and electrical engineering to the project, as well as ICAT and security design.

The Porter hangars were constructed in two phases - the first was completed in late 2023, and the second in 2024 Q1. The complex is part of a series of projects to revitalize the Ottawa Airport to accommodate increased air travel demand in the National Capital Region, and will serve as a primary maintenance base, with 200 local hires, including 160 aircraft maintenance engineers, shop technicians and administrative support staff.

The hangars span approximately 86 metres, and house up to eight aircraft, along with various repair and parts modification shops.

One of the project’s key design criteria was to exceed current energy efficiency standards, in line with the airport’s commitment to net-zero operations by 2040 or sooner. The hangars were designed with sustainability in mind; for example, some of the important features include:

A predominantly electric fleet of vehicles for towing and servicing aircraft, as well as ground support
Design criteria exceeding current energy efficiency standards
Constructed with approximately 35% recycled steel that can be recycled at the facility’s end of life
Constructed from materials with 28% lower embodied carbon than conventional tilt-up assemblies
City fire hydrant system is fully supplemented by an onsite underground water storage tank capturing approximately 1.2 million litres of excess rain/stormwater to avoid overstressing existing city mains.

HH Angus is also working with Scott Associates Architects on Porter Aviation's Saint-Hubert Airport Terminal project, a new zero-carbon terminal that will serve an estimated four million passengers annually. We were also involved with the original revitalization of the Billy Bishop Toronto City Airport that was completed in 2011, as well as its further expansion in 2014, and have been working with Porter Aviation since its inception.
