This document provides plans and details for retrofitting an existing 5-story building with a concrete masonry unit and wood floor structure by installing structural steel and a concrete slab. The proposed retrofit will remove the 2nd floor and central load-bearing wall, replacing the 1st floor with structural steel and a slab on metal decking. Spread footings will be installed in lieu of the continuous stem wall and footings, and shoring will be required during removal of floors 1 and 2. The document outlines the components of the proposed structural steel retrofit design and provides details on installing the spread footings and ensuring proper loading and connections.
