Local 130 UA Parking Garage

Scope/Solutions

The Chicago Journeymen Plumbers Local Union 130 UA is one of the largest straight-line plumbing locals in the United Association. The Chicago office at 1340 West Washington Boulevard hosts major events in the 800- and 250-seat halls and undertook a project to replace the existing surface parking lot with a new 600-car garage. SGH served as the structural engineer of record for the project.

SGH designed the post-tensioned, cast-in-place concrete structure for the seven-story parking garage. Highlights of our design include:

  • Layouts to accommodate ground-level and second-floor retail, and amenity space for the union
  • Caisson foundations set back from the property line to align with perimeter columns
  • Post-tensioned slabs designed to accommodate future mechanical penetrations and facilitate construction sequencing by providing temporary openings in the center of each slab for the tower crane
  • Flat parking areas to allow for flexibility and the option for converting parking levels to office or residential space
  • Steel-framed walkway hung from post-tensioned slab above
  • A cast-in-place underground water storage tank design to fit within the building’s column grid
