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

One of the busiest interchanges in the nation, the Jane Byrne Interchange in downtown Chicago connects I-90/94, I-290, and Congress Parkway. SGH investigated claims that this work resulted in settlement and damage to CUPPA Hall, a mass masonry structure with timber post-and-beam framing.

Union Station Transit Center

Led by the Chicago Department of Transportation, the Union Station Transit Center project creates an off-street Chicago Transit Authority (CTA) bus terminal adjacent to Chicago’s bustling Union Station. The transit center allows commuter rail and Amtrak train passengers to directly connect to CTA buses through an underground walkway. Working as a subconsultant to the bus canopy and curtain wall subcontractor, SGH served as the structural engineer of record to design and detail the canopy superstructures.
