Award Criteria

  1. Architectural Excellence
    The project was a 3500 lb capacity, three-stop inline elevator, hoistway and machine room with 47'-5" of travel from the ground floor to a two-story press box at the top of the stadium grandstand. It was built to be ADA wheelchair and stretcher compliant. The finished structures of the hoistway and modular machine room were clad in an exterior to match the press box and trimmed in the school colors. The interior of the elevator car features white enamel doors, durable, brushed stainless steel fixtures and laminate covered wood core walls for stability, durability and sound control, as it is in service at a school. The three modules that comprise the project include one machine room and two modules that were stacked to make the hoistway. The architectural challenge was to build an impressive and matching elevator hoistway that would be completed on a tight time schedule, prior to the dedication of the new sports complex and opening home football game.
  2. Technical Innovation & Sustainability
    The technical innovation is demonstrated by the manufacturing process itself. Unlike its stick built counterpart, a Phoenix Modular elevator is built horizontally and will remain that way until installed. This project started with two 4" X 4" tube steel frames with proper door openings and supports. It was then clad in Densglass sheathing for 1 hour fire protection and door frames were added. On the inside of the hoistway, drywall was applied and elevator rails were welded to the structure, aligned and plumbed. Simultaneously, the elevator cab was constructed and then inserted onto the rails in the hoistway. Another unique aspect of multiple module, modular elevators is rail installation. To ensure perfect alignment of the rails, the two modules of the hoistway are joined together and then the rails are added in as one unit. They are then taken apart for transport and united again on site. This ensures a perfectly aligned elevator rail system and a smooth riding elevator.
  3. Cost Effectiveness
    Cost effectiveness is accomplished in several ways. First, the modular built elevator is not subject to cost over runs due to weather. The elevator hoistway is built in a factory and the work is never slowed by outside weather conditions. Second, the elevator cab is built at the same time as the shaft. This saves significant time and like the hoistway, the cab fabrication is not subject to excessive cold or heat. Third, material waste is significantly reduced in production. We know the exact total amount of materials for each elevator and consider layout of the materials to keep costs lower. Finally, other site work does not have to accommodate the elevator construction. Oftentimes, the elevator is the most time consuming element of a major building project and creates delays. The Center Grove project clearly demonstrated that other construction can be completed uninterrupted, as the elevator was built off site in just four weeks. It was then shipped, set in place in a day, and ready for inspection three days later.
