Bishop Ireton High School

Scope/Solutions

The Diocese of Arlington wanted to expand and upgrade Bishop Ireton High School, which has been operating as a private Catholic school since 1964. The multiphase project included demolishing the existing Oblate House to make way for a new 44,000 sq ft STEM education wing and renovating portions of the existing school building. SGH provided structural and building enclosure services for the project.

As the structural engineer of record for the new building and renovations, SGH designed:

  • The steel-framed addition with columns and foundations coordinated with the Oblate House’s existing deep foundation elements
  • A steel-frame for a trellis feature for a vertical garden wall
  • Structural modifications at the main and auxiliary gymnasiums to create new openings in slender masonry exterior bearing walls
  • Strengthening long-span roof joists to support suspended gymnasium mats and rooftop equipment
  • Steel-framing for an 11,000 sq ft mezzanine in the auxiliary gymnasium
  • Structural components for the main entry, including a new steel-framed vestibule, an accessible ramp, and stair
  • Repairs for damaged and deteriorated steel, concrete, and masonry components

Working directly for the Diocese of Arlington, SGH consulted on the addition’s building enclosure design and construction. Highlights of our work include:

  • Reviewing the design for below-grade waterproofing, exterior walls clad with brick and natural stone masonry, metal panel rainscreens, aluminum-framed windows and curtain walls, waterproofing for the second floor terrace, low-slope and vegetative roofing assemblies, and the glass-enclosed stairwell
  • Participating in a mockup of a typical exterior wall
  • Reviewing related submittals, visiting the site to observe installation of the enclosure, witnessing performance testing, and helping the project team address field conditions
