HOSPITAL DESIGN
develop a commissioning procedure throughout the entire commissioning process; sampling is not an option in a tertiary care medical facility. Equipment data is collected from these test sheets, and initial project management schedules established. These schedules are altered as experience with the building systems is developed. Proper operation of a complex building requires well-trained staff armed with specific information, not a sales presentation. To this end, FM included a comprehensive specification section in the building system design intent manual that details the scope of training required for each system, the number of hours required for each session, and whether classroom training and/or recording is necessary. HSC has a technical training officer to coordinate this important step.
‘Dress rehearsal’
During the commissioning stage, it is not unusual for the consulting engineers to revisit their design and implement changes. These changes are captured in the building system design intent manual. Once the contractor and HSC’s commissioning team are confident that all systems are working properly, the life safety systems are tested. “We throw the switches for complete loss of power,” explains Craig Doerksen, divisional director of facility management at HSC, and member of the Women’s Hospital redevelopment project steering committee executive. “We need to know with absolute certainty that the building, and ultimately the people inside it, will be safe under extraordinary circumstances. We look at the redundancies that are built in to ensure that backup systems come on and function as they are supposed to.” From there, the team pulls together all the players for the consultants’ life safety test rehearsal. Each consultant – mechanical, electrical, structural, and/or architectural – must witness the functionality and provide letters of

certification to confirm that their respective designs are reflected in the actual building and they work for their intended purpose.
Rehearsals continue until the team is satisfied that the systems will successfully meet City of Winnipeg building inspectors’ approval. Consultants prepare verification letters to accompany the application for an interim occupancy permit, while city inspectors set a date and time for the test.
Occupancy permit
Once the new Women’s Hospital successfully passes the life safety systems test, and the building design team warrants that the project is substantially complete, the City of Winnipeg will grant the occupancy permit. At this point, HSC will take full responsibility for the building and move into the next phase of readiness preparation for opening within a year of substantial completion.
HSC needs the 12 months following substantial completion to install, test, and prepare staff, equipment, work processes, and clinical systems. Staff will run through simulations of the move as opening day nears. Once the team is confident that care can be provided safely, the new Women’s Hospital will welcome its first patients.
A new standard
Years ago, FM staff had to dig through outdated owner and operator manuals and multiple versions of shop drawing submittals in an effort to maintain the equipment, as built drawings were lost or outdated. With feedback from the shopfloor, the entire process of capital project design, commissioning, and building information capture, has been reinvented.
HSC will need the 12 months following substantial completion to install, test, and prepare, staff, equipment, work processes, and clinical systems.
Now, once the new Women’s Hospital is populated, a benchmark will be established. Screenshots of DDC points of all equipment and systems will be noted, as will set points and operating conditions based on outdoor conditions at the benchmark date. This reference

information will be used from time to time to compare current operating conditions to the benchmark and review the amount of variance.
Power factor correction Power consumption and power factor correction will also be noted, as well as water consumption, and steam and chilled water loads. Reasons for change could be environmental or seasonal, or due to fluctuating occupancy demands and operational hours. Technical problems will be flushed out from these reviews, and unexplained abnormalities examined. HSC’s energy engineer will be available as an additional resource when tackling these technical issues.
However, regardless of all the DDC alarms that have been set up, the user’s phone call to maintenance dispatch provides the best feedback on the building’s performance. Upon receiving a work order, FM technicians will review the EBI (enterprise buildings integrator) graphic display of the area to determine any systems problems before meeting with the user. Operating conditions will be compared with set points. Often the problem can be solved at this stage. Beyond this, the technician will visit the user for additional information and a site/ equipment survey. Working together with the interrelated systems shop technicians, solutions will then be developed (unless it is something beyond FM’s control, such as the seasonal changeover and draining of cooling units). Feedback from these visits can lead to changes in DDC programming and set points.
