Abstract:
This presentation will discuss the tower crane innovative scheme for construction in a challenging urban site. A new residential development is currently being constructed in the heart of downtown Chicago along upper Wabash Avenue near the Chicago River. The project consists of an 18-story, 150,000 sq ft residential vertical expansion to an existing “in-service” 4-story cast-in-place reinforced concrete parking structure that was built in the 1980’s. The project site is bounded on the west side by the existing congested two-level Wabash bridge viaduct constructed in the1930’s, an existing 54-story residential tower to the east, and private driveways to the north and south of the site. Since the 18-story concrete structure is being built on top of an existing parking garage, new foundations were not required. Extensive review of the existing Wabash Bridge and existing garage structure as well as the tower crane were performed and will be discussed in this presentation.
