This project consisted of the strategic dismantling of the Annex parking facility, which was located above the I-94 expressway in Milwaukee, Wisconsin. Its critical importance came to light when Omega, engaged in bridge demolition work on-site, discovered that the location earmarked for a new highway pier coincided with the site of the Annex building. To adhere to the planned schedule for reopening the reconstructed I-94, it was imperative to remove the Annex structure within a stringent four-month deadline. The building’s composition of concrete floor decks, masonry walls, and a structural steel frame posed additional challenges to the demolition process.
