Project Delivery Method: Design-Bid-Build

Architecture

Architecture:
The architectural style was developed to follow the traditional western Pennsylvanian school. This consists of an almost all brick structure with punch out windows. Since this is a functional school building the flow is designed to maximize space and efficiency. This being said the corridors are laid out with classrooms flanking both sides, to further maximize efficiency the stair wells were placed at the corners. One of the other methods used to create a more functional building was placing the rest rooms on the inside corners.

Major National Model Code: TBD
Zoning: TBD
Historical Requirements: None
Building Envelope:
Waynesburg Central High School is a combination of renovation and new construction. This being the case there are multiple systems implemented throughout the building. Most of the roof will be getting renovated. The previous system was not uniform across the roof, and in places there are as many as three layers of various roofing systems that are being removed. The new roofing material is a TPO. This is a form of new rubber roof, which will be installed on the portions that receive new roofing as well as the new additions.
The part of the building that is being renovated implemented a standard from of construction being a load bearing masonry wall with a brick façade. The building utilizes punch out windows in the masonry façade. The entire exterior of the building is clad with brick. Windows are inset in a series of buttress type supports.
The new building tries to mimic the window system implemented in the existing building. The architect decided to change the structural system in the new additions, while keeping a similar appearance. The structural system chosen is a pre-cast concrete system, with the interior of the building being steel columns and beams, and also utilizing several load bearing masonry walls. The pre-cast concrete is present on the exterior of the building surrounding the window openings, where the spaces will then be in filled to the sill level. Similar to the existing building the exterior of the building will be primarily brick, the difference being the pre-cast concrete columns will remain exposed creating a distinguishable difference between the existing building and the new addition.

Building Stats Part 2

Construction:
Waynesburg Central High School is being delivered as a multiple prime contractor project with a construction management agency. The contracts state that the means and methods of construction are the responsibility of the prime contractor. Each prime contractor holds a lump sum contract with Central Greene School District. One of the methods of delivery is the phased delivery method which allows occupancy in all other areas of the building while construction commences.

Mechanical:
Being primarily a renovation project much of the structure is existing to remain, causing complications to transfer to a central air handling system. A unit ventilator system will subsequently be utilized in the existing building simply replacing the existing unit ventilators. The unit ventilators to be installed are a four pipe system, the building required a total of 73 unit ventilators. A central air system will be used in the additions. A total of 15 pre package air handling units will be installed in the new additions.

Electrical:
Waynesburg Central High School will be upgrading the entire electrical system. A new electrical room will be constructed in the basement of building G beside the mechanical room. The main service to the building is a 3 phase 4 wire system, with 277/480V power. The main breaker is a 3000 Amp, 3 phase breaker. This is the primary feed to the building and supports much of the electrical system. The building will utilize a back up generator that will provide 150KW/180KVA.The power provided will be in 120/208V, 3 phase power and will only run the items that are essential in an emergency situation.

Lighting:
The lighting system and several of the receptacles are powered by the secondary electrical system which is a 208Y/120V service. Waynesburg Central High School uses 40 different types of luminaries, many of which are variations of fluorescents.

Structural:
Waynesburg Central High School additions utilize a precast concrete system as the primary structural system. These precast concrete columns and beams were cast off site by Concrete Fabricators, in Wheeling, West Virginia and trucked in. When the concrete arrived on site it was then set in place by a 45 ton mobile crane. Precast concrete was set in several different lifts at various stages of the project requiring the crane to be brought on site for concrete erection four times. The project also employs some of the standard practice methods in western Pennsylvania schools, which is the use of load bearing masonry walls. Masonry fills between the columns and also line the corridors and is the partitions between interior spaces.
