BUILDING STATISTICS I
Note: While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work in progress for this thesis project. Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Jonathan Fisher. Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design.
General building Data
Building Name: Westinghouse Building 4
Location: Cranberry, PA in the Cranberry Woods Office Complex
Building Occupant Name: Westinghouse Electric Company
Size: 120,000 sq.ft.
Stories: 3 above grade, 4 levels total
Owner: The Ferchill Group, Chicago IL (http://www.ferchillgroup.com/)
General Contractor: Turner Construction (http://www.turnerconstruction.com/)
Dates of Construction: Aug. 2009 to Nov. 2010
Cost: Approx. $25 million
Delivery Method: Design-Bid-Build
Architecture: For the architectural and functional components of the building the goal was simple; maximize open floor space for cubicles and allow as much natural light into the building as possible. The building exterior is also meant to mimic, but not be identical to Westinghouse’s 3 other buildings on the same property. The building was constructed using the IBC 2003 manual for specifications and requirements. The zoning requirements for this building had to follow the Cranberry Township Non-Residential Building and Zoning Package, which can be found at the following website, http://www.twp.cranberry.pa.us/DocumentView.aspx?DID=22. This document provides all of the Township’s requirements, regulations, and applications for a building of this magnitude and purpose. There are no historical requirements or effects that go along with this building or the site on which it was built
Facades and Roofing: The façade of the Westinghouse Building 4 will consist of 3 different materials; brick, polished aluminum, and glass. The brick and aluminum facades alternate levels as you go up the building. The brick is red brick that adheres to ASTM C 216 standards and has a grade of MW or SW. The compressive strength of these bricks is to be 4400 psi, the absorption will be less than 30 g/30 sq in. per minute, they will be rated “not effloresced”, and shall be manufactured by Watsontown Brick Company. The polished aluminum sections will be made of a tempered aluminum alloy metal and reinforced with steel. The panels will have a high-performance organic finish applied to them. The color and gloss will be Dark Grey PPG Duranar Exotic Coating as was selected by the architect. This aluminum curtain wall will have tolerances of 1/8” from plumb in 10 ft and ¼” from plumb in 40 ft. The last part of the building façade is the window system of the building. The window system has aluminum framing that matches the color and specifications of the aluminum curtain wall system. The main building façade windows will be made of PPG Industries, Inc. ¼” thick Sputter-Coated Float Glass. This type of glass is tempered and heat treated for maximum hardness and break resistance. It will be coated with metallic-oxide or metallic-nitride coatings, which will give them their physical properties; Solar Heat Gain Coefficient: .31, Shading Coefficient: .36, U-value: .28 average, and Visible Light Transmittance: .51. The roofing of the building is to be a Thermoplastic Polyolefin Roofing Membrane. The membrane will be fabric reinforced and .015 in thick. The exposed face color will be white and the material will have a 225 lbf breaking strength.
Sustainability: The windows of the building are the only real sustainability feature of the building. The windows are very large and let in the majority of the light required by the office inhabitants. This cuts down on lighting costs and studies have shown that natural light improves workers work ethic and productivity.
