Award Criteria

  1. Architectural Excellence
    This project provides space for 24 standard classrooms to accommodate up to 528 additional students. The building has five special use classrooms for the school’s art, music, speech, and special education programs. It also includes a cafeteria with a warming kitchen, administrative offices, a library, tutoring center and learning lab, and a 3,000 square foot multipurpose exercise room with athletic flooring and a 14 foot ceiling height. We incorporated a mix of masonry and EFIS that complimented the existing structures and provided a cohesive appearance to the campus. The elevations also had to comply with city ordinances for architectural requirements that called for specific ratios in the placement of vertical and horizontal articulations all while being within the constraints of the project budget. Interior finish selections were largely driven by the educational use and included painted gypsum, resilient and ceramic tile as well as an acoustical drop ceiling.
  2. Technical Innovation & Sustainability
    Using Ramtech’s Slab-On-Grade PMC System, the floorless building sections were crane-set directly onto a five inch 4,000 psi reinforced concrete slab foundation with 18’ deep drilled belled piers. The slab was cast with weld-plate embeds at all steel column points, allowing the structure to be welded to the finished slab. The slab’s design and necessary soils remediation was dictated by a geo-tech’s report. Steel clear-span trusses are used throughout the building allowing for unlimited future configurations of the space. All interior partitions are full height to the roof deck aiding sound attenuation. In the multipurpose exercise area, the roof modules were constructed atop a clearstory knee wall that was supported by the adjacent modules allowing a 14’ clear ceiling height. Use of recycled materials was incorporated throughout the structure. All materials were manufactured within 500 miles of the project site.
  3. Cost Effectiveness
    Ramtech developed our Slab-on-Grade PMC System as an efficient means to provide concrete floors while deal with the highly expansive soils found throughout Texas. Conventional pier and beam PMC installations require a grade-beam or stem-wall foundation supported typically by under-reamed drilled piers. Then a conventional block pier supports a steel modular floor system with a corrugated steel deck and three inches of poured light-weight concrete. This redundancy of structures (expense of foundation and a modular floor system) adds considerable cost to the project. By utilizing a poured-in-place conventional concrete slab as prescribed by the geotechnical engineer, then placing a floorless module directly atop the slab, three things are achieved at a lesser cost: Better floor acoustics due to more mass (quiet floors); A grade level entry is provided at all exterior doors; There is no crawlspace to ventilate, greatly reducing the possibility of poor indoor air quality.
