Tribune Tower

Central utilized a mast climber and swing stages rigged from pipe scaffolding installed around the 8 flying buttresses that rise from the 25th floor to the 34th floor.

Two floors of limestone veneer were removed and salvaged for the installation of new 2-story storefront windows.
Central aided in the installation of a cathodic protection system in an attempt to preserve the structural steel in the flying buttresses.
As work on the tower progresses, Central infilled window openings due to structure alterations on the backside of the building with concrete masonry units.
Baskets and a swing stage scaffold hang from the pipe scaffolding and buttress on the east elevation.

Central was engaged in 2018 to begin an extensive restoration and renovation of the Tribune Tower complex. Key facets of the project include the unique renovation of the Tower’s eight, 8-story high stone flying buttresses as well as reconfiguration of the masonry openings throughout the lower three floors of the complex’s five buildings. Cathodic Protection has been installed to help preserve the structural steel supporting the buttresses. Sections of carbon-stained limestone have been cleaned. Special care is being taken to salvage as much original stone as possible for re-use throughout the buildings. With a scheduled completion in 2021, the iconic, neo-Gothic skyscraper is set to house high end condominiums while the smaller, surrounding buildings will enhance Michigan Avenue’s retail space.
