FEBRUA RY 2019 | 69 Jim Pattison Children's Hospital RENDERING COURTESY HENRY DOWNING ARCHITECTS Jim Pattison Children's Hospital by ROBIN BRUNET T he positive impact of the nearly- completed Jim Pattison Children's Hospital to patients and families requiring care from across the prov- ince cannot be underestimated: the 400,000-square-foot facility, designed by Henry Downing Architects and ZGF Architects, is the only children's hospi- tal in Saskatchewan and represents a substantial leap forward in the deliv- ery of health care. The 176-inpatient bed facility is comprised of a number of pediatric ser- vices including Saskatchewan's first dedicated pediatric surgery suites, with integrated induction rooms (allowing parents to be with their child while anesthesia is administered); a pediatric emergency department and pediatric outpatient clinic; and an entire floor dedicated to pediatric inpatient care. Other firsts include maternal inpatient and outpatient care being sit- uated on one floor, allowing pregnant mothers to labour, give birth, and stay with their new baby in the same pri- vate room; and a neonatal intensive care unit in which each baby and fam- ily have their own private room, with sleep areas within patient rooms. During the design phase, close attention was paid to consider aspects of the design that could provide a more comforting environment for patients and families. "For example, colour-changing LEDs representing the Aurora Borealis on the ceiling of the lobby are a visual highlight of the facility," says Marj Olson, electrical technologist at WSP Canada Inc. The $285.2-million Jim Pattison Children's Hospital exhibits an usual degree of creative architectural expression: Henry Downing Architects and ZGF designed an exterior cladding of Tyndall stone at the base, cham- pagne-coloured aluminum shingles. and coloured glass fins, plus reflective silver metal cladding on the upper por- tion of the facility. "The metal reflects the changing light of the day," explains Henry Downing Architects' partner Keith Henry. Both architecture companies (ZGF was responsible for the medical plan- ning, conceptual design, and interiors, while Henry Downing co-ordinated with the project's engineers and detailed the building envelope) and Saskatchewan Health (SHA) through a formal community engagement pro- cess sought direct input from patients and families from across the province. Craig Ayers, SHA director, plan- ning and construction, Jim Pattison Children's Hospital, explains, "We wanted our new facility to impart a sense of home to patients and their fam- ilies, and therefore we needed to hear the voice of the families and learn from their experiences. From the outset of the design process, we had family advi- sors embedded with our clinical design teams so we could benefit from their input and experiences. We also hit the road with a small team to hear directly from communities across the province." A congested site occupied by a parkade that had to be demolished to make way for the new hospital was a major challenge for the development. Anthony Mirvish, senior associate with structural engineers Entuitive, also noted that poor soil conditions required caisson foundations instead of pad footings, while sand and pres- surized water layers complicated their installation. He adds, "The hospital was a trap- ezoidal base with a large atrium and square forms above. With the architects, we created as much of a reg- ular, vertically continuous structural grid on the hospital's east side as was possible, to simplify construction." Mirvish says it was crucial to understand the parkade and Royal University Hospital structures, as the new hospital would be linked to them. "For example, a bridge between the new and existing hospitals had to hang off a floor in the old hospital above the one to which it connects, to avoid disrupting hospital opera- tions." Toronto-based Mirvish's work was aided by structural engineers BBK Engineering Saskatoon Ltd. Foundation pilings and construc- tion on the main building began in September 2015, and two tower cranes proved to be an indispensable boon. "A 236-foot tall crane allowed us to lift equipment and supplies from the back end of the parkade, over drive lanes, and across the parkade to the construction site," says Tyson Snider, senior proj- ect manager at Graham Construction. "A smaller crane helped build the main structure of the building." The site constraints also obliged concrete pumps to be installed on the opposite side of the parkade. "It pumped concrete to the placing booms over a distance exceeding 450 feet," says Snider. Aiding the process was the early implementation of management prin- ciples. "We created a master schedule as well as used LEAN values for the interior finishes and the Last Planner System at the foreman level," says Snider. "Abiding by these systems allowed us to wraps portions of the project several months ahead of schedule." Another invaluable aid to Graham was Fieldwire: field management software that streamlined job site co-ordination, improved collaboration among the 350 workers on the site, and enabled crews to address deficiencies immediately (it also greatly facilitated the implementation of an estimated 800 change orders). Darren Wingerak, president and senior principal engineer at Daniels Wingerak Engineering Ltd., points out that, "Because the entire project was designed as a full 3D BIM model using Autodesk's Revit software, we were able to use the Revit model to look in detail at areas in advance of the instal- lation, thus adding value and reducing time for on-site project co-ordination." Wingerak and his team selected systems and technology that would provide long life and serviceability. They include a comprehensive heat recovery system to recover waste energy from all major exhaust streams, and chilled-door rack-cooling technol- ogy in the major data centre, which allows the heat to be easily rejected back into the recovery system. Wingerak notes that, "Every detail was important and examined for inno- vation and practicality. For example, a uniquely simple domestic hot water recirculation system ensures that hot water is always available at the fixture without the usual 10 to 30 second delay. It seems a small point, but for nurses who may wash their hands over 50 times a day it represents a tangible benefit." As of January 2019, the Saskatchewan Health Authority was preparing the building for operational occupancy this fall. "Many of us have been working on this project for the better part of 10 years, but the work has been so intense that the time has flown by," says Ayers. "We're very excited to provide this new hospital to the province."
