Mount Sinai Hospital

Phase 3 Redevelopment

Phase 3A represents a major renewal of the hospital's main site. HH Angus was engaged to provide mechanical and electrical engineering for the Renew Sinai redevelopment.

HH Angus worked with the Hospital, Stantec Architecture and other consultants to develop the Functional Program and Blocks Schematics for Ministry of Health and Long-term Care [MOHLTC) stages 2 and 3.1 submissions.

As part of our scope, we were involved in the investigation of existing infrastructure and systems. The age of the existing facility, together with previous renovations and multiple facility architects and consultants provided a challenge in obtaining a complete set of existing design conditions. We were provided with drawings in various forms (eg: PDFs. scanned hand-drawn images, AutoCAD and part plans), ranging from the original build to the most current renovation projects. We translated the relevant information into AutoCAD and, in with numerous site investigations, assembled a comprehensive set of record drawings detailing the existing systems and functions.

The scope of the project included a new Surgery Department, renovated and expanded Emergency Department, Critical Care, Medical Device Reprocessing Department, Integrated Practice Unit, Ambulatory, and labs, as well as miscellaneous relocates and decants.

Some of the key challenges of this project included reworking the major mechanical and electrical infrastructure to upgrade systems to current standards, and the integration of disparate systems with existing facilities.

Extensive renovations were implemented. To address the challenges of implementing new infrastructure, HH Angus provided extensive background information and on-site investigation to mitigate risks to the Hospital.

Minimizing disruption to hospital services was of paramount concern in scheduling the renovations. To ensure continued hospital operations, our design solution included planned sequential shutdowns minimized inconvenience to staff, patients and visitors.

Under a standing offer with Mount Sinai, we served as Mechanical and Electrical Engineers of Record and were involved in a variety of projects for Phase 3, including: peer review, fluoroscopy unit. Maternity Clinic renovation, Mouse MRI Lab, Biorepository Lab, Roth Lab, Bremner Lab, Distributed Antenna Systems, lobby upgrade, art gallery/ security/office renovations, and IMIT Planning for Phase 3 Redevelopment and renovations to multiple departments.

Island Health | Infrastructure BC

Cowichan District Hospital Replacement


Three times the size of the existing facility, the new Cowichan District Hospital on Vancouver Island will reflect BC’s new model for integrated healthcare by placing patients, families and communities at the centre of care decisions throughout the continuum of care. The goal is to reduce wait times, improve care and outcomes, and provide better value for healthcare expenditures.


HH Angus is part of the design team under The EllisDon Healthcare Infrastructure Consortium, and is providing mechanical and electrical consulting engineering to the 607,000+ ft2 project. The new facility, with an estimated budget of $1.44 Billion, will have 204 private or semi-private beds to support best practices for infection prevention and control, with the capacity for increased beds as population growth warrants. The emergency department will be three times the size of the current ER and is expected to accommodate 42,000 visits by 2035.  Additional services include mental health facilities featuring a 20-bed inpatient unit and dedicated ICU, culturally safe services and spaces, 7 operating rooms, increased CT scanning capacity, and built-in MRI facilities.

Island Health specified a low energy, low carbon design solution. HH Angus, working with the rest of the design team, devised a number of innovative solutions and the project is now aiming to be Canada’s first CaGBC Net Zero Carbon hospital and first fully electric hospital. As well, the project is targeting LEED Gold certification.

This is the first Alliance Project Delivery for HH Angus, with many differences from a conventional project delivery model. It is a far more collaborative process, where the owner, contractor and design team act as one entity. Both the quality of the submitted design and the ability of the team to work together were key factors in the proponent evaluation.

Royal Inland Hospital

New Patient Care Tower

Royal Inland Hospital is a tertiary level acute care hospital serving a catchment area of approximately 220,000 residents in the city of Kamloops and throughout the Thompson, Cariboo and Shuswap regions of British Columbia.  

The 290,625 ft2 new Phil & Jennie Gaglardi Patient Care Tower (PCT) is a nine-storey building that includes a surgical floor, 13 operating suites, patient floors for mental health and medical/surgical beds, a neurosciences and trauma unit, perinatal centre, labour and delivery rooms, and neonatal intensive care unit. There are also two underground parking levels, administrative and clinical spaces on three lower floors, an intermediate mechanical floor, and 3 inpatient levels topped by a penthouse containing the heating, cooling, and emergency power plant.

Phase 2, currently underway, consists of a number of renovations within the existing facility, including a completely renovated Emergency Department. Phase 1, which opened in July 2022, targeted LEED Gold certification. HH Angus provided mechanical and electrical design services for the PCT, which was constructed adjacent to the existing hospital under a P3 contract.

Designed with direct input from local healthcare workers, the PCT streamlines access to hospital services through a single main entrance. A new post-anaesthetic recovery room in the adjacent existing facility’s renovated space will be constructed in Phase 2. Other clinical spaces include a substance use inpatient unit, a child and adolescent mental health crisis intervention program, maternal and child services, and respiratory therapy services. Non-clinical spaces include reception, patient registration, a rooftop helipad, underground parkade, retail space and a new home for the Royal Inland Hospital Foundation.

Mechanical design includes energy-efficient heating and cooling systems with a variety of heat recovery features. The project has an ambitious energy use target and HVAC systems were designed with this benchmark in mind. HH Angus was able to solve a problem the Hospital was having with the existing distributed hot water boilers by upsizing the new plant to serve the majority of the hospital campus. The ventilation design includes redundant capability and outbreak control, and exhaust air heat recovery, as well as providing for future flexibility.

The Health Authority expressed an interest in the ability to conduct smudging ceremonies in any patient room without having to make significant modifications to the current ventilation design and infrastructure included in the project.  HH Angus found a means for using the ventilation system as originally designed and applying a unique operational sequence to minimize capital cost changes while providing the ability to undertake smudging activities in any of the patient rooms on the Medical/Surgical and Mental Health Adaptive inpatient units.

A central focus of the design team was to work with the commissioning team to ensure proper operation of the new facility. The design team is now helping monitor ongoing operations to recover and reuse as much waste heat as possible. This effort concentrates on the heat recovery chiller plant operation to meet as much of the building’s heating load as possible using waste heat. This contributes to minimizing the production of GHGs from heating energy sources and, in turn, improves decarbonization for the new facility. New electrical services include a 25 KV service from BC Hydro serving a new outdoor substation powering the existing campus and PCT. New redundant 25kV to 600V FR3 transformers feeding the new tower were provided in the new main electrical room. Three new 2MVA diesel generators provide emergency power backup to the new patient care tower and the rest of the existing campus if utility power is lost. 600V distribution on both utility and generator power are provided with high resistance grounding to increase resiliency and reliability in the event of a single ground fault. Numerous low voltage systems were provided including fire alarm, lighting control system complete with daylight harvesting, circadian rhythm tunable lighting in the Neo-natal ICU, and electrical metering.

Helipad Design

The rooftop helipad is served by a number of mechanical and electrical systems to help keep the pad surface clear of snow and ice and to provide appropriate safety lighting to meet all requirements. Fire protection and life safety systems, such as foam suppression, were carefully coordinated and designed to ensure full coverage and containment in the event of a discharge.

Systems Integration

 Integration with the existing hospital systems was a significant challenge and required numerous connections to the adjacent facility. Requiring multiple site visits, it was determined the two facilities could be successfully integrated by enclosing an outdoor courtyard between them, transforming it into a four-season space that will benefit patients, staff and visitors. On the electrical side, backfeeding the existing facility with new 600V HRG generator backup required careful analysis of existing distribution to ensure compatibility for all existing equipment to the new 3 wire distribution on emergency power. A detailed sequence of operations for black start sequence and retransfer of automatic transfer switches to normal was developed and commissioned to ensure proper operation for different failure scenarios.

Lions Gate Hospital Power Plant

The new underground power plant at Lions Gate Hospital is a key piece of infrastructure to enable construction of a new acute care facility in North Vancouver. 

The existing steam-only power plant at Lions Gate Hospital did not meet seismic requirements and was quite dated. HH Angus replaced the existing plant with a new buried installation that includes boilers, medical gas, plumbing and electrical equipment, as well as the routing of services through an existing tunnel system. 

The new design for the underground plant is a hybrid of hot water and steam boilers; this design will help to reduce both energy use and greenhouse gas emissions. It’s an innovative design that recovers heat from the power plant via a heat pump system and rejects heat back into the reheat systems. An architectural feature boiler stack was included in the design.

The RFP originally required relocation of the bulk O2 system; however, following a number of design iterations, the result was the provision of an Oxygen Concentrator system instead.

Implementation of the Fraser Health Authority’s BIM standards was also required for the project. This is the first time these standards were applied at HH Angus, and the work helped to develop a baseline for future Fraser Health projects.

Among the challenges of the project:

– With limited knowledge of the existing site, it was necessary to obtain all background information within a short timeframe through access to existing drawings (dating back to 1960s) and performing multiple site reviews.

– To provide the best solution, HH Angus explored multiple options, above and beyond the requirements of the original RFP and, although the timeline for completion of design and implemention of new BIM standards was aggressive, all deliverables were met on time.
