Analysis of laboratory data has suggested that settlement of the organic clay, as a result of the fill above it, can be expected to be about 25 mm in every ten years. After the collapse, a team from the Occupational Safety and Health Administration (OSHA) came to the site and started an investigation. Building experts have identified structural issues like water seepage in basement, external walls, windows and roof leaks as potential risk factors for internal damage and failures in residential .

In Nigeria, the common causes of building collapse have been traced to bad 10 fdesign; faulty construction; foundation failure; extraordinary loads, use of unqualified contractors and poor project monitoring and above all, lack of enforcement of building codes by the relevant Town Planning Officials (Badejo,2009; Falobi, 2009; Bamidele, 2000). /Type /Group Investigation revealed the following conditions: After the investigation results, an emergency plan was immediately launched for underpinning. /Subtype /TrueType Officials said they expected a number of local, state and federal agencies also to be involved in the inquiry, though it was not clear which agency would lead the effort.
