Engineers: Ikoyi building initially designed for 6 floors — changes made were inadequate

November 16
The Nigerian Institution of Structural Engineers (NIStructE) says the 21-storey building that recently collapsed in Ikoyi, Lagos state was originally designed to be six floors.

The structure, which was being developed by Fourscore Homes, caved in on November 1, leaving over 40 people dead.

Femi Osibona, owner of Fourscore Homes, is one of the 45 persons who have so far been confirmed dead.

In a statement on Tuesday, Kehinde Osifala, NIStructE president, said the changes made to the project appear to “have been seriously inadequate”.

“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,” Osifala said.

“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.”

The NIStructE president also said lack of proper quality control during the construction of the building was evident.

“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,” he said.

“It is our view that the outcome of our preliminary investigation will give a general indication of what likely led to the unfortunate incident.”

Ikoyi building collapse: Why we withdrew further services —Construction company



Segun Adewole
1 November 2021

A letter has shown that Prowess Engineering Limited, the company that began the construction of the building which collapsed in Ikoyi, Lagos on Monday withdrew from the project in February 2020.

The company withdrew its services on grounds that it no longer shared the same vision with its client believed to be Fourscore Heights Limited as addressed in the letter.

Prowess Engineering Limited, which had constructed two other buildings for its client, said it couldn’t guarantee the integrity of the third (collapsed building) from anything above the fourth floor.

The letter titled, ‘Re: Proposed Gerrard Terraces For Fourscore Limited,’ was signed by the company’s managing director, Muritala Olawale who confirmed its veracity to our Correspondent.

It read, “This letter is to formally inform you of the withdraw of our structural consultancy service from the above named project. We arrived at this decision due to the fact that we no longer share the same vision with you as our client in terms of how the project is being executed.

“We can guarantee the integrity of the first two buildings and also work done up to the fourth floor of the third building supervised by us provided specifications have been met in terms of the required concrete strength. This we do not have control over as we do not have the concrete cube test results of each stage of the building till date. Also, note that we are not taking responsibility for any other construction errors that may have occurred overtime on the project.

“Furthermore, we request that our company’s name and logo be removed from the project board and also kindly notify all necessary approving authorities of our withdrawal from the project.

“We regret this decision and the lost opportunity to do business together. We look forward to future cooperation in other projects.”

Meanwhile, The PUNCH learnt that three survivors have been rescued while four dead bodies have been recovered from the rubble of the collapsed building as of the time of filing this report.

We are yet to hear the last of this.

LASBCA granted approval for 15 floors, while the Fem Hamzat debunked the claims to declared an approval for 21 floors.

The outcome of the probe panel will put the conflicting reports to rest

They way and manner this LASBCA people run around sites you’d think they know what they doing. Only egunje nothing else.

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

The man was a religious fanatic who believed his faith in Jesus will hold the building together. Because no one in his or her right mind, who works with professionalism, diligence, logic and reality of things would allow a building that was initially designed for 6 floors to be taken all the way up to 21 floors!!!

They were asking him how he was able to achieve the projects, instead of him quoting his experience, skill and expertise he said it's Grace of God, it's faith in God, God this, God that. Religious fanatics are the worse to work with...

Someone must be held accountable

3. Don't threaten, support or DEFEND violent acts against any person, tribe, race, animals, or group (e.g. rape).

Building collapse attributable to nature are understandable though some avoidable but objectively still acceptable.

Man made, avoidable as it seems though tempting and inviting as it may be, it is inexcusable.

Hmm

Ah.. i believe say if the thing no collapse dem fit shift am from 21 storey building to 28 and from 28 to 30..

Just GREEDY developer bribed his way to increase the floors as the demons of greediness increased in him along the way.
The collapse of the towers of greed simply showed the fate of every greedy corrupt and incompetent Nigerian in the public sector and private sector.

A COMPANY THAT KNOWS ITS ONIONS!!! THANK YOU FOR SHOWING THE WORLD THAT ITS NOT POSSIBLE TO MAKE THINGS WORK BY CUTTING CORNERS. CALAMITY AWAITS THOSE WHO LOVE CUTTING CORNERS. IT MIGHT NOT END UP COMING FROM YOUR FUUUK UP BUT FROM THOSE YOU SPEND THE LOOT OF YOUR DUBIOUS WAYS.

When it went above the designated floors, why didn't those involved take actions? All these stories comi g up are medicine after death.

Typical Nigeria carry religion for head but involved in shady stuff

Different stories don dey pop. Some said 15, some 17 now its 5.

Can you imagine?
So 21 storeys on a foundation meant for 6 storeys?
Just like putting a crane on an 04 Toyota corolla.
Just take a look at the Irons used for both beams and pillars...

NLPoliceWoman:
I feel sad about this always

shame Don dey catch you to use your true moniker...
Pele BBQgriller, you can't defend failure for a long time without people seeing you as a failure yourself

Thought the deputy governor said otherwise. Funny enough the LASBCA chairman was suspended indefinitely from office for chorusing this same line. Meaning for the sake of truth and justice, good conscience and history the man should be reinstated back to the office asap!

From 6 to 21..
Even the devil doesn’t move that way

The collapse was not some freak accident but a result of negligence.

All evidence show that the symptoms of this building are throughout but no one took them serious or they chose to turn a blind eye to it when they should act.

You can’t move from 6 floors to 21 floors in 1 year.
