King Animal Hospital
Fitout and Peer Review
The King Animal Hospital is a state-of-the-art multidisciplinary referral and emergency hospital for small animals and equines, complete with MRI’s and medical gas systems.
HH Angus provided mechanical consulting services for the fitout of the King Animal Hospital. Our scope of work included a peer review and report identifying potential gaps between the base building mechanical infrastructure and the programming and capacity requirements for the state-of-the-art animal hospital. Following the peer review and report, we provided full mechanical design services for the fitout, from schematic design through to construction administration and project close-out.
The fitout included approximately 60,000 FT2 in a 4-storey greenfield facility, accommodating a wide range of program elements including 8 operating rooms, 12 exam rooms, an MDRD sterilization room, laboratory and pharmacy, diagnostic imaging (MRIs, CT Scan) suites, hydrotherapy, and physiotherapy, as well as support and administrative spaces.
The sub-cellar is home to an equine treatment area with CT equipment outfitted with robotic arms, and an MRI with an adjacent horse lift. An arena will be used for equine physiotherapy. A large heated ramp from grade was selected over an animal elevator to provide a safer, and less stressful, mode of transportation for the horses when moving between floors. The small animal services area of the sub-cellar features three aquatic treadmills, a hydrotherapy pool, and a hyperbaric oxygen chamber.
The cellar level includes the staff gym, lounge, meeting areas, and a dog quarantine with an exam room and 17+ dog runs. Oxygen connections to the cages and foot baths in the floor support infection prevention and control.
The ground floor features an equine surgical area, including recovery, dirty surgery area (two surgeries performed simultaneously), and an equine water treadmill. It also houses a treatment area for dogs, cats and exotics, including dentistry area, and a canine showcase area with three surgery, CT, x-ray and neurological rooms with MRI equipment.
The second floor houses staff meeting spaces and amenities. A multipurpose space doubles as a surgical support area, Learning Centre, and workshop.
The base building infrastructure was in place prior to HH Angus joining the project, which meant our team was tasked with working in the confines of a building shell that was already in place. This presented challenges at the cellar level, where the team had to design while accounting for low floor to floor heights.
The hospital had not yet retained any permanent staff during the design stage, and many of the programming elements relied on recommendations from other consultants/doctors/experts during the design-stage user group meetings. Once permanent staff were hired for key departments, the design team worked with the client to make adjustments to the layouts and equipment based on staff input.
Although an animal hospital does not fall under the same CSA standards required for human
hospitals, there is a trend towards meeting those standards in animal care facilities. HH Angus wrote design briefs for systems and features that the client chose for this facility, many of which aligned with CSA requirements for a state-of-the-art human hospital.

Waypoint Centre for Mental Health Care
Chigamik Community Health Hub
Waypoint Chigamik Mental Health Centre is part of a redevelopment project and replaces two older facilities in use since the 1800s.
The challenges of this project included the requirement that the entire building be completely designed in one stage, rather than proceeding with design packages, plus delays in funding during the design process which resulted in a requirement for both a base building package and a fitout package.
To accomplish this, HH Angus coordinated two tender packages and two building permit submissions. Some detailed specifications in each package were interchangeable for the mechanical and electrical tender process. Working with phased schedules ensured that equipment start-up was fully coordinated between the tender packages.
The project faced additional challenges to provide an energy-efficient HVAC system, due to compliance with CSA Z317.2 and budget restrictions, as well as a small mechanical service space. To overcome these challenges, extensive coordination was implemented throughout the project across all disciplines.

University Health Network
Toronto Western Hospital Critical Infrastructure Reliability Project
Toronto Western Hospital (TWH), part of the University Health Network, initiated a project to enhance the reliability of its critical mechanical and electrical (M&E) infrastructure. With aging equipment dating back to 1954, TWH partnered with HH Angus to undertake a comprehensive upgrade project aimed at ensuring the continuous operation of high-risk medical services.
As the prime consultant, HH Angus was responsible for assessing the condition of existing mechanical and electrical systems. Following the assessment, upgrades were made to the facility, including replacing emergency generators, and establishing a new electrical room serving the ORs and the broader hospital campus. Subconsultants, including architectural, civil, environmental, and cost consultants, played crucial roles throughout the project.
To determine suitable locations for generators, extensive investigations were conducted, including structure analysis, examination of building codes, and assessment of environmental impacts. This collaborative effort led to the approval of a new penthouse above the East Wing for generator placement. The final engineering package involved locating the emergency generators at grade in a new fenced area, alongside the supply and installation of two new 1100W emergency generators and upgrades to the electrical network and distribution systems within the powerhouse.
HH Angus leveraged reality capture workflows, utilizing photogrammetry and a Matterport Pro2 camera, to produce a digital 3D model of the powerhouse and infrastructure. Through the efforts of our BIM team, 3D scans were taken of mechanical and electrical spaces, including complex piping and ductwork, to generate point clouds for reference in Revit. These models accurately depict existing systems, including central steam, chilled water, and emergency power systems serving the hospital's ORs and surrounding campus.
Additionally, the project has been recognized for excellence, with the generator exhaust stack winning in the category of Steel Works – Sculptures – Outdoor Pavilions at the Canadian Institute of Steel Construction's Awards for Excellence. https://hhangus.com/award-for-excellence/

Toronto General Hospital Rapid Assessment Centre (RAC) Expansion
HH Angus was engaged to provide mechanical and electrical engineering, IMIT consulting, and lighting consulting services for this 20,000 ft2 phased renovation at Toronto General Hospital. The space now includes a Rapid Assessment Centre, Diagnostic Test Centre, and Admitting and Pre-Admission Clinics.
The emergency department (ED) was designed to serve ~ 20,000 patients annually but was receiving more than 55,000 patients To better manage these volumes, a dedicated Rapid Assessment Centre (RAC) was added so that ED staff can triage lower acuity patients to the new "fast track" area, enabling primary emergency areas to care for more complex patients. Our team worked in conjunction with the client and other consultants to perform a pre-tender constructability review. This review included potential approaches to minimize disruption outside areas of construction, identify potential installation challenges, and complete pre-demolition of the first phase of work to identify any unknown site conditions in advance of construction. Due to the age of the existing space, there was a high probability of building systems and equipment being beyond their service life, and a certainty that codes and standards relevant to the design of the new space had changed. To address this and mitigate any risks, HH Angus performed a pre-design review to identify any specific potential issues with the new space and recommend steps to further address the unknowns. Scanning and 3D captures were performed regularly throughout construction, using Matterport Pro 2 and a Theta V 360 Camera. This provided the client with regular site progress updates and, in future, will allow for dimensionally accurate references for locating MEP services behind walls and ceilings. It also allowed for a more focused presence on-site, as construction progress was made available remotely to a range of project stakeholders amid COVID-19 pandemic restrictions. The existing ventilation systems presented a significant gap for the project, as their capacity to support the new functions of the space was unknown. To address this, HH Angus investigated and presented several options for review, taking into consideration the client’s budget, schedule, and planned upgrades for existing infrastructure.
