The Northeast PA Office Building is composed of two main building areas. The first building area, a single story business area, will house approximately forty offices. It will also include spaces that will serve as conference rooms, restrooms, copy rooms, break rooms, and mechanical rooms. The second building area, a single story warehouse area, will be a five bay work/wash/storage area capable of allowing full length tractor trailer to easily pull through. The site will also include forty‐eight spaces for future employee’s daily parking, including two American Disabilities Act (ADA) spaces. The rest of the 18.85 acre site will be used as a gravel laydown yard.


Building Enclosure

The office building and shop building both utilize a pre‐engineered metal building system. The façades and roofs of both buildings are to be 26‐gauge corrugated Galvalume panels. Galvalume panels are steel sheets that are commonly used for both roofing and siding applications for many industrial type buildings.


Sustainability Features
Although the Northeastern PA Office Building is not attempting to be LEED certified, it will include some systems that are environmentally friendly. One feature of this building that exudes this characteristic is the wash bay in the shop building. The equipment installed in this area is a bio‐treatment system which will allow water used to wash equipment to be reused.



The Northeastern Pennsylvania Office Building is Phase 1 of a 5 phase project for the owner. The next two phases of this project are nearly identical to Phase 1 and will also be design-bid-build projects. The last two phases will be five-story office buildings that do not have any shop buildings or gravel laydown yards. A nine month schedule has been provided for the construction of Phase 1, but the owner has expressed that the substantial completion date is not a hard deadline for this project. This is because the eventual tenants will not be occupying the space until approximately one month after the tentative substantial completion date. The largest driver of the project schedule will be the erection of the structural steel system. If the pre-engineered metal building subcontractor delays the project in any way, the general contractor will have difficulties finding areas to reduce the schedule to compensate for the lost time. This was the primary reason for including a substantial completion that is actually about one month prior to the actual project deadline.



The structural system utilized on the Northeastern Pennsylvania Office Building is a pre-engineered metal frame. It is composed of rolled steel pieces that for large spanning structural frames. The largest frames used on this project span approximately 60 feet across the shop building. All frames are composed of four pieces that can range up to about 5 feet in depth, and can also taper down to about 10 inches. The structural frames will be braced in the lateral directions by horizontal purlins. Metal Galvalume siding will be fastened to the purlins as an exterior sheathing that will also provide additional lateral stability for the structure. The steel frames will be placed on concrete pier footings that have an average size of 36" x 44" and are all 34" deep. These concrete piers will be constructed on top of concrete spread footings that have an average size of approximately 78" x 88" with an average depth of 18". These reinforced concrete footings will effectively distribute the load of the structure to the ground below.



The shop building and the office building on the Northeastern Pennsylvania Office Building each consist of different mechanical systems that condition the spaces. Thirteen gas-fired infrared heaters hung form the structure of the shop building are used to provide heat in the colder months. Three large fans that are also mounted to the structure of the shop building are used to force the warm air down and more evenly distribute the heat within the building. Ten gas furnaces will be used to provide heat within the office building. A system of ductwork that runs within the plenum above the ceiling of the office building will distribute the warm air throughout the space.



A fully redundant electrical system will ensure the Northeastern Pennsylvania Office Building will not lose power for an extended period of time unless the backup generator malfunctions. An 800A service at 480V will be directed through an automatic transfer switch (ATS) before entering the building. If the power supply is interrupted, the ATS will activate the building's backup generator to provide power to the building. The 800A service power will run directly to a main distribution panel. From here, two 480V lines will be run to power panels. Two separate lines will be run to transformers that will step down the voltage from 480V to 120V. These lines will then provide power to five lighting panels. The majority of the lighting within the office building consists of recessed fixtures that house two fluorescent T5 lamps. The primary lighting within the shop building is suspended T5HO lamps that are common for high-bay areas.


Fire Protection

The entire Northeastern Pennsylvania Office Building will be sprinkled with a wet-pipe sprinkler system and is to meet the requirements of the NFPA codes, the Fire Marshal's office, and the owner's approving insurance company.

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. Modificationsand changes related to the original building designs and construction methodologies for this senior thesis project are soley the interpretation of Christopher Havens. Changes and discrepencies 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.
The Capstone Project Electronic Portfolio (CPEP) is a web-based project ans information center. It contains material produced for a year-long Senior Thesis class. Its purpose, in addition to providing central storage of individual assignments, is to foster communication and collaboration between student, faculy consultant, course instructors, and industry consultants. This website is dedicated to the research and analysis conducted via guidelines provided by the Department of Architectural Engineering.
