Holy Spirit Hospital’s ED Addition and Renovation is considered a 51,000 square foot addition and renovation project. The purpose of this project being built was to improve patient and hospital facilities, along with an effort to make the hospital a Level II Trauma Center. The addition will cost approximately $22 million, completing a total of 8 different phases of construction throughout the hospital. Some examples of areas being improved upon are the treatment and locker rooms, CT scan area, Isolation and Bariatric areas, Volunteer and new offices, and a nurse station. Some unique challenges faced during construction were the installation of the helipad on the roof and creating an elevator shaft through the existing building. The collaboration of all parties involved is necessary in order for the project to be successfully completed.
Holy Spirit Hospital was recently bought by Geisinger within the past couple years. Since the merge, they wanted to continue their success in the health care by transforming the hospital’s emergency department into a Level II Trauma Center. In order for them to acquire this certification Holy Spirit must have 24-hour immediate coverage by general surgeons along with other specialty surgeons, provide trauma prevention and continuing education programs for staff, and incorporates a comprehensive quality assessment program. Another major factor to become a high level of certification is the implementation of a helipad, used for immediate critical care responses.
Major National Codes: 2009 International Building Code
The entire Emergency Department of Holy Spirit Hospital’s existing structure is to be demolished. This demo is necessary for the excavation of the basement, where the majority of Mechanical and Electrical equipment will be placed. An important focal point during the excavation of the basement was the soil nailing of the existing buildings foundation walls. This was necessary, so that while excavating the site the soil nailing will prevent soil from caving out from under the foundation and hold the existing building in place. While this is happening it is critical to implement ICRA, to prevent any construction particles from entering the hospital, such as, dirt, dust, and debris.
Cast-in-place concrete for the buildings foundations will include mixture design, multiple placements of formworks, steel reinforcements, and a variety of accessories. These accessories will include dovetail anchor slots, waterstops, reglets, expansion joint fillers, and performed construction joints. The mix design to be used is Portland cement, ASTM C 150 types I &II, and normal weight aggregate, ASTM 33. While, this activity is being performed, certified surveys of the concrete frame formwork, anchor bolts, leveling plates, and bearing plates will executed. All exposed concrete slabs and floors must be in accordance with ADA requirements.
The mechanical room will be located in the new addition's basement. The basement will be the location where all the AHUs (9500 to 17500 CFM) and variable air volume terminals are placed to supply a desirable thermal comfort to all occupants residing in the east wing of the hospital. All cooling towers and chillers (Net Capacity 750 Tons) will be placed in the power house located directly behind the hospital. There were two unique challenges the project had to undergo were the mechanical fed from the new building when the phase turned over, and the location of the outside air shaft.
Electrical System
The building is occupied as a hospital, so it has a very complex system of normal power with a lot of back up emergency branches, and multiple locations for the electrical system. Some of these back up emergency power branches included: critical branch power, life safety branch power, and equipment branch power. The hospital is installing a Unit Substation to be used as the main distribution system. The main switchboards that are set in the basement are called Switchboard NORSE rated at 480Y/277V 3Ph 4W 60Hz. These switchboards distribute power throughout the building. There are 5 Automatic Transfer Switches with 600-1000 amps, 480V/60Hz, 3 pole, a Power-Dry Transformer 750 KVA, and Metal-enclosed switchgear 15KV. This power is dispersed to multiple panel boards that are scattered throughout the building. In case of an emergency, where the power goes out, there is an interrupter switch that transfers it to the emergency power substation that is located in the power house.
Holy Spirit Hospital’s uses LED fixtures as the new additions light source. Most of these fixtures have correlated color temperatures of 4000K, and are either universal or 208/120V. All of the led fixtures utilize two different methods of energy saving technologies. The first method is the integral dimming capability, and the second is the utilization of the Lutron Ecosystem driver.
Holy Spirit Hospital’s façade is made up of multiple systems, that each require the correct construction installation to efficiently enclose the building. The new addition is made up of terra cotta panels, curtainwalls, composite metal panels, and polished CMU. The enclosure is comprised of waterproofing/ air barrier, 4” thermal insulation, and wall fasteners in all locations where metal panels or terra cotta panels are used. The terra cotta panels are hung onto the façade using vertical support aluminum extrusion, which clips are fastened to, and then a 20mm wide terra cotta normal middle clip is attached. Since the terra cotta panels are being shipped from Germany, and there is a very long lead time the owner required an onsite mock-up. Both of these systems, terra cotta and metal panels, are not considered the vapor barrier, but simply work as a weather screen for the insulation behind the systems.
Building Enclosure
The structural steel members performed on the project should consist of W-Shapes (ASTM A 992/A 992M), channels and angels (ASTM A 36), base plates, splice plates, cap plates, moment plates, and web plates (ASTM A36), Cold-formed hollow structural sections (ASTM A 500), and high-strength steel castings (ASTM A 148/A 148M). Along with metal deck support angles, required bracing, welds, and fasteners, and bolts connectors and anchors. Floors are composed of concrete floor slabs on metal decking supported by wide flange beams. All connections must be bolted using high strength bolts (3/4 inch diameter bearing type) or welded. The steel will also contain a hot-dip galvanized finish.
Fire Protection
Holy Spirit Hospital falls under the jurisdiction of the Pennsylvania Department of Health, which enforces the Life Safety Code, and the Borough of Camp Hill, which enforces the Pennsylvania Uniform Construction Code Construction Requirements and Means of Egress. All new construction will be Type IB under the IBC and NFPA 220 Type II (222). Columns will have 3 Hour fire resistance. Floor construction, including beams, will have 2-hour fire resistance. All shaft enclosures will have 2-hour fire resistance. Spray fireproofing is applied to all concealed structural steel members, and intumescent paint is applied to all exposed structural steel members.
Sprinkler systems will be zoned to correspond with the individual smoke compartments. This will involve the provision of new sprinkler control stations and modifications to existing systems in the Holy Spirit Hospital Building. A separate control station will be provided for each compartment. Electronically actuated deluge valve for fire suppression system will be located within the building shell. The fire suppression line piping shall be 4” dia. Hot dipped galvanized and furnished with drain valves as necessary to allow complete drain down the normally dry exterior piping following system operation.
The heliport will use an AFFF fire suppression system that will be a normally dry system outside the building. This sire suppression system line piping will be from deluge valve to oscillating monitor/nozzle. The design standard will be NFPA 418 standard for heliports, and have a classification H-2 (helicopters 50 to 80 feet long). NFPA 418 recommends AFF application rate of 0.10 GPM/SF landing pad surface area. AFFF foam concentrate shall be 3%, low expansion AFFF, freeze protected, and UL listed.
Transportation
A new Otis elevator will be installed in the existing building, which will cause some constructability problems. Since it is being installed in the existing space, two floor slabs must be cut to make room for installation. Along with the floor cuts, all conduits, wiring, and pneumatic tubing must be redirected. Along with a new elevator, a new stairway (Stairway J) will span from the basement to the second floor. Stairway J is located by the new seclusion rooms on the first floor, and the new physician’s offices on the second floor.
Use of existing elevators designated by Owner will be permitted; clean and maintain existing elevators in a condition acceptable to Owner. Use of existing stairs designated by Owner will be permitted; clean and maintain existing stairs in a condition acceptable to Owner. At Substantial Completion, restore all elevators and stairs to condition existing before initial use. Conditions of use include: do not load elevators beyond their rated weight capacity, and provide protective coverings, barriers, devices, signs, or other procedures to protect elevator car and entrance doors and frame. If, despite such protection, elevators become damaged, engage elevator Installer to restore damaged work so no evidence remains of correction work.
Telecommunications
Throughout Holy Spirt Hospital a typical surface mounted single section raceway will utilize a 1” min. systems conduit stubbed above accessible ceiling/bushing terminated by division 26. The quantities of conduits will be determined by the quantity of cables. All wires will use a cable tray distribution system, installed above all ceiling panels. The telecommunications system will also use a grounding bus bar for most supports.
