Hershey Research Park Building One
Building Statistics Part 1
General Building Data
Dates: April 2006 – May 2007
Site Master Plan
The bulk of the foundation consists of drilled piles. This deep foundation system type is often utilized in areas where shallow spread footings are not recommended due to low soil bearing capacity. This system would consist of 3, 5, or 7 grouped drilled steel piles tied together with a concrete pile cap. A concrete basement wall is utilized to create the basement floor level. A poured-in-place concrete slab on grade installed over a crushed stone aggregate sub-base and a vapor barrier supports the first ground floor level.
The main framing system of the building is steel columns, girders, and beams. The beams support the floor system that consists of concrete on top of metal decking. In addition, steel studs are used to create a composite action between the floor system and the beams, increasing the strength. The most common bay size is 32.5’ x 32’ with most other bays being smaller. The beams in these bays are W21x44 that frame in to W27x94 girders. The deck is 18 gage and 3” deep with a 4.5” normal weight concrete topping. Throughout the superstructure of the building is the lateral system. The lateral resisting system utilizes multiple moment frames at the core of the building.
The mechanical systems of the building are a very important part because this is a research facility. The tenants do product testing that involves different types of chemicals that require the labs to be ventilated properly. On the roof, there are two 25,000 CFM VAV air handling units. Located in the basement are four boilers as well as two air-cooled chillers. These provide hot and cold water throughout the building.
The electric service to the building is 45KVA, 480-208Y/120V, three phase, four wire, coming from the transformer located outside. This feeds into the main electrical room located in the basement. There are a total of 19 panel boards located throughout the building, ten are 480Y/277 V panels and nine are 208Y/120 V.
The construction of the building lasted about one year and was constructed by Whiting – Turner Construction. The construction was from April 2006 – May 2007 and cost approximately $10.7 million dollars. This project was completed using a design-bid-build delivery method.
Hershey Research Park Building One has three elevators and two stairwells. There are two passenger elevators located in the central lobby directly past the main entrance. The third elevator is a freight elevator located on the south end of the building. The two stairwells are located at opposite ends of the building. One is located at the north end and the other at the south end.
The building contains a consolidated addressable fire alarm system. Manual pull stations are located at all exits and doors leading to the outside of the building. Smoke detectors are located in all corridors and all code-required areas (elevators, duct detectors, door release service). In addition, the building uses a sprinkler system that exceeds code requirements. There are many rooms the contain hazardous chemicals so an adequate sprinkler system is needed. Exposed structural columns also are spray fire proofed to obtain the required fire rating.
|The Capstone Project Electronic Portfolio (CPEP) is a web‐based project and 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, faculty 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.
