Architecture
The hospitals architectural firm, Stantec, designed the hospital with a modern, clean look with a lot of sharp lines, simple textures and an open feeling. Contrasting this open feeling is the individual hospital suites, which are all completely private rooms capable to be totally enclosed instead of a typical curtain pulled around the bed. This design feature was decided upon by the immediate community in the area for whom the hospital is meant to serve. The first two levels are primarily visitor areas, medical rooms for short visits, and area for staff and personnel. The top three levels are almost entirely rooms designed for any long term or overnight stays in the hospital.

Building Enclosure
Building Facades
There are two typical facade types in this hospital. The primary facade is a precast architectural panel, typically 8" thick with prepunched holes for windows, supplied by U.S. Concrete. The secondary facade is an aluminum composite panel system. These facade types vary by thickness, aestetic style and color, but these are the basic assemblies that make up the facade.

Roofing
Roofing for the hospital consists of EPDM (ethylene propylene diene monomer) roofing membrane either mechanically fastened or adhered to a large layer of roof insulation, which sits atop gypsum wall board that is supported by the metal roof deck.
Sustainability Features
PinnacleHealth West Shore Hospital is obviously a very energy intensive building, with modern medical equipment and rooms full of medical support devices. The hospital still employed several energy saving features into the design of the building. First, the mechanical system has several devices to save energy and money, one being variable speed equipment, such as motors and pumps and an advanced control system that can monitor and adjust them throughout the days demand to lower peak energy consumption. To lower energy consumption further, the buildings control system can vary the amount of outside air coming in to the minimum amount when it isn't needed, thus reducing the energy expended to condition it, and to the maximum amount when the conditions are right to utilize the air. All lighting throughout the hospital is energy efficient lighting, and the parking lot lighting is on photosensor switches with timer overrides.
Primary Engineering Systems
Structural System
West Shore Hospital's structural system is a partially composite deck with wide flange beams, girders and columns. The primary floor deck is 3 1/4" LW concrete on 3" deck to provide a total floor thickness of 6 1/4". Infill beams between girders are primarily W16x26 with girders sized to W24x55. The beams framing into the columns are larger, as they are part of the lateral system, and are W21x44. The floor layout is a very typical and simple 30' x 30' bays only changing where openings are present to allow the passage of ducts and mechanical equipment through the floor. All columns are W12 shapes, ranging in weight from W12x50 to W12x120. The roof framing is the same as a typical floor framing for future expansion. Most columns stub up beyond the roof level to allow attachment when this will be needed. The typical roof deck is 1 1/2" metal deck with GWB, insulation and EPDM roofing membrane.
The lateral system is a combination of two elevator cores and a flexible moment frame. Every column and girder or column and beam connection is labeled as a typical flexible moment connection. With the area not being a seismically active region, alot of bracing or full moment connections aren't required.
Mechanical System
PinnacleHealth made great energy saving choices when designing the mechanical system. This hospital uses a VAV (variable air volume) system with ductwork distribution. This allows control of the incoming or exhaust air to maximize efficiency. Two Leverbrook boilers are used for hot water, and the building has an internal loop for hot water to the rooftop air handling units, which have hot and chilled water coils for air temperature adjustment. York brand rooftop chillers also provide conditioning. This system also has variable speed fans and pumps and an advanced control system that allows very fine control of the conditions.
Lighting/Electrical System
This hospital uses a 480Y277V electrical system fed from two different substations, a primary line, and a secondary line. These are connected through a transfer switch. Emergency generators are constantly prepared for use and every operating room has its own battery backup system so power will never fail during an outage. Energy efficient lighting is used throughout the building, and the parking lot lights are on photosensor switches with timer overrides to save energy costs.
Construction
West Shore Hospital was constructed within a 2 year period, and was completed May 2014. The project delivery method was IPD. Building Information Modeling (BIM) was successfully implemented in this project saving alot of time and money for the owner.
Additional Engineering and Support Systems
As any hospital requires elevators, West Shore has two primary elevator cores. The larger core houses 4 elevators, two oversized for patient bed transportation, and two regular sized elevators. The smaller core houses one medium sized elevator, primarily for visitors and patients who are mobile.
