ARCHITECTURE / BUILDING ENVELOPE

 

The architecture that influenced the Health Care Center comes from a mix of the existing building’s architectural features, and the surrounding housing from the boarding school.  Most of the building’s façade is either brick veneer or cementicious painted siding with aluminum clad windows and aluminum fascia and soffit.  These features were chosen to match the art deco style of the existing building, originally built in the 1930s.  To fit with the surrounding housing, parts of the Health Care Center have pitched roofing with fiberglass shingles.  One area, where the penthouse is located, has a metal panel system for the façade.  Also sun shades were added to the Health Care Center to make it a “green building.”

 

The building’s roofing system will also help label the Health Care Center a “green building.”  The intent is to become LEED certified.  The building will have a green roofing system called Garden Roof.  The Garden Roof consists of a monolithic membrane, a root barrier and protection layer, a moisture retention layer, water drainage, retention and airation layer, a filter, and is topped with light weight soil and plants.  This roofing system will retain water for the plants and roots, drain water off the roof and through the gutter system, and ventilate to help reduce the growth of fungus and keep the plantation alive.

HISTORY

 

The Health Care Center is located on the campus of a boarding school in central Pennsylvania.  The boarding school was originally a vision of a wealthy and successful businessman and his wife who worked and lived in the area.  He originally founded the boarding school back in 1909 for children who were less fortunate.  The Health Care Center at that time provided their services not only to the children of the boarding school, but to the local community as well.  As time passed and the school grew so did the need for a bigger medical facility.  Today the boarding school serves boys and girls in financial need with housing, education, as well as medical and psychological health care.  The new additions to the Health Care Center will provide more room for the children to get any medical and psychological aid they may need.

 

 

SUPPORT OF EXCAVATION

 

 

There is no support system being used for the excavation.  This is due to the fact that all excavation will be benched back.  The water line determined by the geotechnical engineer was found at a depth 20’ below the existing ground surface elevation.  The basement level of the Heath Care Center will not reach the depth of 20’ below ground concluding that a dewatering system is not needed.

 

 

DEMOLITION

 

 

The Health Care Center is 80% new construction and 20% renovation work making up the 100,000 SF of total construction.  Due to the fact that the existing building was originally constructed in the 1930s, hazardous materials were constructed in the original design of the building.  A special demolition contractor has to remove asbestos and lead paint during the renovation work of the existing building.  Also, the additions have to be completed before renovation work can begin.  This is because the Health Care Center must remain operational for the students.  Also, all existing HVAC and lighting, including wiring, fixtures, raceways, light switches, and receptacles are to be removed from the existing building.

 

 

STRUCTURAL

 

 

The frame of the Health Care Center is a typical structural steel frame.  Each steel column is erected on top of cast-in-place concrete spread footings.  Foundation walls will be poured in the south addition.  Also part of the south addition will have a basement.  The rest of the buildings perimeter will have a 3 foot deep continuous footing.  Also the rest of the building has a 4” slab-on-grade.  All cast-in-place concrete will use both horizontal and vertical formwork.  Most of the building’s framing is made up by wide flanges with metal decking and a 4”slab-on-deck.  The roofing uses wide flanges in some areas and steel joists in other areas.  Some examples of this are the gymnasium roof and other low roof areas.  For the crane to cover all of the 100,00SF of the Health Care Center, it will be moved to three temporary locations, sitting on a concrete pad.

 

 

MECHANICAL

 

 

There are a total of 10 air-handling-units throughout the Health Care Center.  There are three located in the basement while the other seven are on the roof.  The three in the basement will serve the existing building and cafeteria area, while the other seven will serve the gymnasium, the penthouses, and the rest of the additions.  Throughout the building there are exhaust fans, VAV boxes, cooling towers, and humidifiers.  An Electric Control System will be operating and monitoring the air system.  The mechanical system is very important for the Health Care Center.  One reason being a section of the building will be used as an infirmary.  The air must be clean in an infirmary to insure diseases cannon spread through the air.  Another reason is that the building must maintain good indoor air quality for the building to be LEED certified.

 

 

ELECTRICAL/LIGHTING

 

 

The Health Care Center’s electrical system is composed up of a 500 KVA, 150 KVA and two 30 KVA dry transformers.  The 500 and 150 KVA transformers are located in the basement of the building.  These transformers are converting the electricity down to 120/208 V and distributing the power to panel boards located on the first and second floors.  The two 30 KVA transformers are located in the penthouse area where they will be converting the electricity to 120/208V and distributing the power to panel boards around the penthouses.  Most of the lighting in the building is by fluorescent light fixtures; although there are in some areas incandescent and metal halide fixtures.

 

 

MASONRY / FAÇADE

 

 

All of the CMU in the Health Care Center is load bearing.  The block wall will be built up along the foundation wall or continuous footing.  It will be reinforced by rebar then grouted.  Then there is brick veneer that will be tied into the CMU by anchor ties.  There will be an air cavity between the CMU and brick.  Most of the building has a brick façade except where the penthouse and cafeteria are.  The penthouse has aluminum siding and the cafeteria has aluminum clad windows sitting on CMU block and brick veneer.
