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.

The Toronto Western Hospital Critical Infrastructure Reliability project exemplifies HH Angus's commitment to delivering reliable solutions for healthcare facilities.

Fanshawe College

IoT Data Lake

The College’s overarching goal was to streamline their data management process by consolidating disparate IoT platforms into a single accessible platform for measurement and research.

Fanshawe College needed a comprehensive data lake for all campus IoT data, beginning with two solar panel arrays. Their existing process involved physically going to each building’s measurement platform to download its data, merge the information in Excel format and perform a manual analysis.

HH Angus served as smart building consultants to the project, providing digital design services. We reprogrammed the PLCs (programmable logic controllers) of the solar panel arrays, enabling data transmission to AWS IoT core. The resulting data is now stored in a data lake where it is presented with analysis on a centralized dashboard, providing a unified and efficient solution to the College’s data management challenges.

One of the challenges of the project centered on communications and technical access. Collaboration with multiple academic and IT departments proved challenging due to communication issues with various stakeholders involved in the original solar panel array. To address this, our team coordinated multi-department troubleshooting meetings, fostering a collaborative atmosphere that was focused on progress.

Also, gaining access to the PLCs for essential programming changes became complicated due to staff turnover at the client. An unintended consequence of this was that new staff members were unfamiliar with the PLCs. To remedy this, our team assumed more of a technical advisory role than had been anticipated originally, to the point of involving technical support from the PLC manufacturer to assist the College’s technicians. Solving these issues underscores the project team’s adaptability in overcoming unexpected challenges.

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.

Thunder Bay Correctional Complex (TBCC)


The TBCC involves replacement of aging jail and correctional facilities with a new 345-bed, multipurpose complex. Both the existing Thunder Bay Jail and Thunder Bay Correctional Facility are among the oldest provincially-run adult correctional facilities, built in 1928 and 1965 respectively.

The new TBCC updates automation and technology to address issues of health, safety and security, and introduces efficiencies around design, technology, and the use of space. HH Angus is providing mechanical consulting engineering and vertical transportation consulting to the EllisDon Infrastructure Justice design team.

The TBCC is targeting LEED Silver certification and LEED Resilient Design pilot credits through the United States Green Building Council. The design focuses on energy efficiency, healthy indoor environments and reduced greenhouse gas emissions. The complex will also include views of nature, allow ample natural light and feature dedicated Indigenous cultural spaces, such as smudging space and sweat and teaching lodges.

The new facility is the first of its kind for an Ontario correctional facility, incorporating design features that promote rehabilitation of inmates. It will also improve access to programming, living conditions and education, while updating automation and technology.

The TBCC project has presented several challenges to our design team, including a compressed schedule and the involvement of numerous stakeholders. It has also been interesting on a technical level: mechanically, the various modes of operation and interconnection of systems are quite complex, necessitating a high degree of flexibility within the capacity of the mechanical equipment. The building construction featured a precast exterior with block walls, requiring very close coordination with trades to align openings and allow access for equipment.

Due to the secure nature of the facility, the mechanical system was integrated seamlessly into the architectural features, all accessible equipment is provided in a secure location, and all building systems interact
with the BAS.

The facility will include a connection to an existing 50-inmate facility — the Thunder Bay Modular Built Facility — located southeast of the TBCC and currently under construction. The project also involves the design and construction of a 4,000 ft2 wastewater treatment facility to allow for a fully self-sufficient and self-contained facility.
