Fort St. John Hospital & Peace Villa

HH Angus participated in the integrated and sustainable design process, assessing several different mechanical concepts focusing on heat recovery, improved space air distribution and high-efficiency equipment. Considering the climate, extensive consideration was given to balancing the use of 100% outdoor air systems with total enthalpy heat recovery wheels, with the need to reduce energy consumption.

Mechanical and electrical engineering for this new build acute care community hospital included related services such as laundry and food services, and a replacement residential care facility. The hospital provides 58 inpatient beds with full diagnostic and treatment facilities, three operating rooms, endoscopy suite, and 124 residential care beds. Part of our scope, via our affiliate ACML, was to provide the hard Facilities Management for this project.

The project has been certified LEED® Gold and includes specific energy saving elements as a key component of the design. We worked extensively with all other design team members to meet aggressive energy consumption targets without increasing capital costs.

Also notable was the design and construction of the complex and high-efficiency heating plant featuring a series of condensing hot water boilers piped in a cascading temperature arrangement. The focus was on delivering a well-sealed and insulated building to reduce building envelope energy losses and allow the heating boilers to run at peak energy efficiency. This will provide the client with long-term energy savings, as heating costs have traditionally been very high.

The specification of the pad-mounted generator enclosures saved both time and money. Unconventionally, the generators were pre-fabricated and installed in sound-attenuated enclosures before being shipped to site. This allowed for quick ‘plug and play’ installation when these units arrived on site.

Lighting strategies were crucial, with a target of 30% energy reduction below ASHRAE standards while still meeting CSA light level requirements. Implementation of an extensive low voltage lighting control system further reduced energy consumption.

Vertical transportation elements included three passenger elevators and six service elevators.

For the IMIT scope, the Angus Connect team designed a new wired/wireless system, network and infrastructure to help improve workflow with the introduction of RFID tagging to help with inventory and distribution, as well as laying a robust foundation for a future Real Time Location System. Additional major systems included telephone, nurse call, public address, patient entertainment, intercoms, video conferencing and patient monitoring. Our team also planned for and added the infrastructure for the new digital modalities and connection to a centralized PACs system, which improved diagnosing and reporting, and facilitated consultations between staff members.

Mental Health and Corrections Facility

The existing hospital  was more than a century old and no longer met modern standards for mental health care. This greenfield facility increased beds to 188, with the adjoining correctional facility housing 96 cells for inmates. Programming and treatment for offenders is separate from services for mental health patients.

HH Angus worked with the facility to develop and review standards and options for IMIT systems, including security and audiovisual. Our team assisted in preparing the staff for operational changes, and in developing their RFP, including performance and technical specifications together with drawings to procure the systems. We also assisted the client in evaluating RFP responses.

Our understanding of technologies that allow the flow of people through a site and facility were very beneficial to this project. We reviewed numerous options in coordination with architectural design; i.e., door hardware, scanners, fencing options, enclosures. These options also covered video surveillance, real time locating services for patients and staff, access control, intrusion detection and perimeter security.

Designing for customized access

This project had four levels of security zoning and required interior, building perimeter and site coverage so that inmates and visitors have access to services within and outside the facility.

Working with many stakeholders 

Our ability to manage multiple stakeholders—security, IT, owner, government authority, etc.—to achieve consensus was a critical success factor in delivering a design that would be operational and effective in such a unique facility.

Penticton Regional Hospital

David E. Kampe Patient Care Tower

This project involves the design, construction, financing and maintenance of a new patient care tower at Penticton Regional Hospital.

The HH Angus team is designing all new mechanical facilities – such as boiler plants and chiller plants – to post disaster requirements, to be compliant with provincial regulations. Also, BC’s Wood First Act requires that sustainable materials be used throughout the building. The winning design included widespread use of wood elements to create a warm, tranquil environment for patients and visitors.

As part of Interior Health’s commitment to sustainability and green buildings, the new patient care tower will be designed and constructed to achieve LEED® Gold certification.

Design for comprehensive services

When complete, the tower will feature an ambulatory care centre, surgical services centre, 84 medical/surgical inpatient beds in single patient rooms, a new medical device reprocessing unit, and program space for the University of British Columbia’s Faculty of Medicine.

Enabling consolidation

The Tower will enhance access to services and improve patient care through consolidation of programs currently dispersed throughout the hospital.

New and renovated spaces

The project includes two phases, Phase 1 being the design and construction of the new tower and 480-stall parkade. Phase 2 will see renovations to the existing hospital to create an expanded ER that will be almost four times the size of the current ER, as well as renovations to the pharmacy stores and support areas.

Gas Drive

Slave Lake Pulp 9 MWe Cogeneration Project

Waste-activated sludge is produced in vast amounts at pulp mills, and is generally sent to be incinerated or landfilled, or can be land applied. Any of these options represented a lost opportunity at the Slave Lake Pulp plant in Alberta. The sludge would instead be repurposed to serve as the main ingredient for anaerobic digestion—a reliable, local, ongoing source of renewable energy.

HH Angus designed a 3 X 3 MWe bio-gas fed cogeneration plant for Slave Lake Pulp, a division of West Fraser Mills. The renewable energy technology integrates energy-efficient anaerobic digestion, using the pulp sludge, into the plant’s existing wastewater treatment system. This allows the plant to generate a methane-rich biogas that produces electricity and heat for the pulping process.

Our scope included: engineering electrical power equipment to integrate from the owner’s 13.8kV switchboard into the electrical generation system distribution to connect the cogeneration equipment; electrical design for a new engineered building housing the cogeneration machines and balance of plant; affiliated balance of plant engine electrical support services, such as high and low temperature cooling, exhaust gas heat exchanger and fresh/waste oil, glycol makeup systems, etc.

HH Angus prepared a 13.8kV single line diagram for the electrical system, from the power generation modules through the switchboards, to the interface to the utility service and existing owner’s distribution system; plus preparation of a 600V & 120/208V single line diagram for the generator, building auxiliary and balance of plant services. We also designed protection and control systems, and connection arrangements including SCADA with AESO.
