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
