Architecture: The building will house both retail spaces and apartments. 81% of the building is dedicated to residential use, 15% to retail, and 4% to business use. The retail spaces are street level. Also on the first floor, in the northeast corner, are the management offices. Apartments are contained on the following five floors. A total of 65 units will be in the building, including 1, 3 and 4 bedroom apartments. Each floor includes a handicap-accessible unit, a common lounge, and laundry facilities. The design of the building starts with spread footing with selective compaction grouting for soil improvement prior to footing installation. There are also strip footings, serving as frost walls, for masonry foundation walls. The building has structural steel with composite slab on deck for the second floor slab and load-bearing block and precast concrete plank for the third floor to the roof. The façade of the building is brick veneer, metal sheeting, and masonry.
Codes: BOCA 1996
Zoning: Residential and Commercial – Retail
Historical Requirements: Site preparation included demolition of two old buildings, one of which (Federal Mogul Building), required approval from PA Historic Museum Commission. The site is located adjacent to railroad tracks that once contained other factory-related facilities. This will be reflected in the façade of the new building and in the awning-style of the windows.
Building Envelope: Exterior façade is structural stud metal framing with brick veneer and metal panels. There are aluminum storefronts at street level at the building’s retail space and the remaining windows are horizontal mullion with projected windows. The roof is a fully-adhered thermoplastic membrane system.
Demolition: The Federal Mogul Building’s demolition had to be approved by the Pennsylvania Historic Museum Commission, which conditioned that certain parts, including lead glass, precast sills, and moldings, to be sold at auction and/or fundraisers. Both the Federal Mogul and the warehouse that were to be demoed contained asbestos pipe insulation that had to be abated prior to demolition. Demolition was carried out with the use of large track excavators with various attachments.
Structural Steel Frame: The structural system is a steel frame with composite slab on deck for the second floor slab and load-bearing block and precast concrete plank from the second through to the roof. Bracing methods used are lateral and moment bracing. Steel erection was completed with the use of a truck-mounted hydraulic crane with a 200 ton capacity.
Mechanical System: The mechanical system includes 3 Roof top air conditioning units - direct expansion (total of 4200 CFM). The bulk of the mechanical equipment is located on the roof of the building, in three main groupings. Sprinklers are outfitted throughout the building, and are designed to Ordinary Group II.
Electrical System: The electrical system includes 800A, 480/277V, 3-phase, 4W Distribution Panel, ¾” to 2-4”, 60-800A copper feeders, and dry type transformers, including primary – 480V, secondary – 208/120V, and ranging 9-500kVA. Lighting consists of fluorescents and halides used, ranging from 120-277V, which are common throughout the building. The electrical room is located on the first floor of the building, in the east corner.
Exterior Wall: The exterior veneer wall is made up of three main materials: calcium silicate masonry units (CSMU), metals shingles, and brick veneer.
Excavation Support: Excavated soil is to be either trenched or vertical with bracing. Also used will be compaction grouting to support the foundation.
