The Nigerian Institution of Structural Engineers (NIStructE) says the 21-storey building that collapsed on the 1st of November in Ikoyi, Lagos state was originally designed to be six floors.

Kehinde Osifala, NIStructE President, Kehinde Osifala made this known via a statement on Tuesday.

Osifala said “There are clear indications of several design brief changes on the project and the engineering and management of these changes appear to have been seriously inadequate.”

“The building that collapsed was initially designed for just six floors, and later to 12 floors, before this was further changed to 15 floors.

“It could not yet be established the adequacy of any properly designed and documented further revision to the eventual (and tragically, final) 21 floors that was being implemented and which collapsed.

“There are also indications that more than two structural engineering design firms worked on the project at different times.

“The preliminary investigation also revealed some evidence of structural inadequacy in the construction and that signs of some structural distress had already started to show within certain elements of the building. Some remedial measures were already being undertaken to address some of this.

“The method of implementation of this was not in accordance with sound structural engineering practices.”

“All the above findings, which are very significant from the structural engineering point of view, need to be investigated further during the detailed investigation stage so that all factors related to the cause or causes of the collapse can be truly established and the appropriate lessons identified and implemented.”
