The Nigerian Institution of Structural Engineers (NIStructE) has said that the 21-storey building that recently collapsed in Ikoyi, Lagos state was originally designed to be six floors.
This was made known in a statement released by Kehinde Osifala, the NIStructE President.
He 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.
Osifala further said “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.”
He reiterated that “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.”
“It is our view that the outcome of our preliminary investigation will give a general indication of what likely led to the unfortunate incident.”
You would recall that the Ikoyi high-rise building that was being developed by Fourscore Homes, collapsed on November 1, leaving over 40 people dead, including Femi Osibona, the owner of Fourscore Homes.
