The project is an existing 8-storey with 2 basements office building owned by Walled City Securities Corporation and located at Victoria cor. Muralla St., Intramuros, Manila City.

The building, built during the early 1960s, has a base plan of about 21m x 38m with a total height of about 30m. The building was constructed using a reinforced concrete dual framing system and is resting on a deep foundation system using concrete driven piles.

The structure has shown advanced signs of reinforced concrete deterioration and needs to be strengthened and upgraded especially to seismic resistance to conform to the current structural code provisions.

ACO performed the detailed structural assessment and retrofitting design for the project.
