This project entailed the construction of a new diagnostic, therapeutic and inpatient building that interfaces with the existing Milton District Hospital building via a service tunnel and walkway. The new hospital provides approximately 66 additional inpatient beds. The key programs in the new building include: emergency, security and surgical services, inpatient medical/surgical units, critical care, maternal newborn and new diagnostic imaging services including the hospital's first MRI machine.
Renovations to the existing hospital were limited to accommodate the new service tunnel and walkway. However, given the sensitivity of the adjacent existing occupied areas, the design and construction team worked closely with the clinical staff and facility managers to achieve minimal disruption to the existing hospital operation. This required constant coordination with the contractors to ensure that the activities on-site accommodated the evolving design to confirm design adjustments were made with respect to the building components. Milton District Hospital is targeting LEED Silver certification.
Sustainability, performance and reliability were major considerations for the design of this new facility. The mechanical systems include a condensing dual fuel boiler plant, high efficiency chilled water plant (with air and water side energy recovery), and low flow plumbing fixtures for reduced water consumption. The plant, arranged to provide N+1 redundancy, meets the peak building load with the largest piece of equipment out of service.
Air handling is provided by low velocity air handling units and ductwork that reduce overall fan energy consumption. Select areas of the new facility operate at 100% outdoor air to promote patient comfort and infection control. Critical areas, such as the Intensive Care Unit, feature parallel redundant air handling units that provide 100% capacity for routine maintenance or failure while contributing to reduced energy consumption during normal operation.
To minimize the risk of interruption from the hospital's ICT infrastructure, a "mission critical" mechanical and electrical design features a highly redundant and available 2N system.
There are two independent live incoming feeders with an automated transfer scheme between the utilities to allow the entire building to be transferred onto one feeder should any one of the two utility sources fail. The hospital also features full generator backup (3 x 1350kW prime rated units), with closed transition capabilities, and a 2N uninterruptible power supply (UPS) system. The main switchboard provides a double ended configuration. Lighting throughout the entire hospital utilizes LED fixtures on a Digital Addressable Lighting Interface (DALI) based platform.
The facility's backbone is redundant and utilizes diversified pathways for fibre optic and copper connectivity. The latest design principals for wired, wireless, real-time locating systems (RTLS), paging, and nurse call are implemented. The data centre in the building is part of an overall Halton Health Services data centre strategy. The design is based on uptime best practices with redundant server, power and cooling services.
Security zones were identified, and created in ways that ensured convenient flow for staff and visitors, without diminishing safety. Consultation with user groups enabled a coordinated approach to door security, access control, and surveillance.
The audiovisual systems at Milton District Hospital are designed and implemented with a focus on user experience and simplicity. AV systems range from facility wide digital signage systems to integrated room systems. Video conferencing is implemented over the Ontario Telemedicine Network (OTN) and augments the installed meeting room systems, including HD cameras, customized control systems, dual display systems and interactive displays. This approach transforms traditional standards-based video conferencing systems into truly collaborative solutions, allowing users to annotate over presentation materials while connected to far-end participants. The digital signage systems offer an opportunity for integration with wayfinding and patient flow systems. In addition, these zoned locations are leveraged to allow for the display of hospital generated content and emergency messaging. A great deal of consideration has been given to the aesthetics of the facility and the result is an extensively AV-equipped environment without bulky and unnecessary installed equipment.
