I know this building. The contractor handling this project is based in Yaba, Lagos as written on the profile board.

The building probably failed due to the following reasons:

1. High axial load acting on the ground columns. A crushing test of sample taken from the site should reveal this.

2. Not using the correct concrete mix required to achieve a particular concrete grade as directed by the structural engineer. A simple test with a smith hammer will give us the average grade of the concrete.

High velocity wind load is ruled out as a possible cause of the collapse due to pattern/direction of the collapse.

You mean an afonja contractor screwed up on this construction and innocent imolites have been receiving unwarranted bashing on this forum?

Since when did people who build thatch houses start building skyscrapers?

This building looks as if it was abandoned and work latter started on it

this building has been abandoned for a long time...

That structure is nothing else than a hotel.... my owerri politicians and business men have a covenant with hotel ownership!!!

Its big business, though I don't hear IMO state listed as a tourist attraction like cross river.

even international conferences are not held there, so what are the hotels for?

Guess they do a lot of fucking in IMO, hence the brothels. (they re definitely not 5 star)

When I look around me and see towering buildings and it serenity I start wondering if this world get too sides, my first time in Lagos it was sight to behold but when I crossed the border I find out that Lagos and the rest of Nigeria cities are over glorified villages that has nothing to offer

Abagworro:
Owerri is a shithole. Incidentally the entire town looks- filthy, shitty and messed up like this.

Chino Owerri is not a shithole like Onitsha and Awka

Imo was the biggest host of conferences in Nigeria under Okorocha but Ihedioha came and started trying to demonize event hosting and hospitality because Okorocha did exceptionally well there. At a point Presidents of African countries were visiting Owerri unofficially on a regular basis.

The columns are like tent poles. How on earth did they expect those tiny columns without fortified steels beams sippprts to hold the heavy structure that the building will eventually become?

Trial and error mudefucking engineers in an unregulated and lawless country.

Imo state particularly Owerri is a jungle and a shithole. There are almost 100% dilapidated roads in Owerri, coupled with filth almost everywhere. Owerri and Aba shares alot of similarities, especially in bad roads and filth.

The only thing going for Imo state is commercial sex hawking and cheap brothels. No sane person wakes up to visit Owerri except to go import their cheap girls that are only good for prostitution.

Don't allow the hopeless jobless old gworo man called abagworo to deceive you.

I doubt both reasons

1. The structural engineer would have checked for that during design .


2. 15-20 Mpa Sumire than sufficient which is 1:5:7 by pan weight which this site engineer would know very well.

My suspicion would be

1. Poor rebar craftsmanship but I doubt ; a seasoned engineer will know to check rebar works over considerably before casting

2. Most likely soil settlement; hence causing redistribution of forces

If I'm not mistaken, that structure is more than fifteen years old. It was abandoned for a long time.

u are mistaken.
It was started about 4 years ago

I am not an engineer. But I suspect the soil too. It could not bear the weight of the blocks being added to the already completed skeleton

By 1:5:7 do you mean 1 bag of cement, 10 pan of sand and 14 pan of coarse aggregate?

If you check well that would hsve been a hotel... Ala Owerri mma mma nu

It could be own by nwafor residing in lagos

Hmmmmm, the engineer handling the project must be prosecuted, he didn't consult COREN at all.

I can never trust Nigeria builders with such a project, na to hire Julius Berger, Simona etc

Firstly, soil test was not done to know the soil bearing capacity, 2ndly, no structural design analysis drawing, I.e, look closely to the picture of the building nd you will see that, all the columns are uniform, note, there is no way a structure of this magnitude will have dsame columns(Pilar's) if there is structural design analysis drawing. 3rdly, no design specifications and the structure is been constructed by unqualified civil/structural engineers. These factors made the structure to collasped.

Sometimes is the fault of the engineers because some of them will use fake materials when they are paid for original materials. And what result do you expect fake materials to give you rather than things like this.

Rochas stopped this man, Ihedioha gave him back approval.

Yungmil:
hmmm

OK guys FTC debutant is here.

want to use this opportunity to thank Mtn for daily 50 free mb, which was used to make this possible.

And airtel, opera, free basics

Mightyhaiz:
hmm.. Perhaps years of burrowings around and within the building by rodents ,reptiles and even insects may have weakened it on all fronts..

Lol, funny you. Insect ko

i know this structure so well, the road around that area Is so terrible and the government never did anything bout it n it seems the structure as been there for a while.

it must be owned by a strong man in the state

thank you ,

thank you so much

Hope nobody died in the building ? Life is more precious than money ...the Engineer supervising the work must be in soup by now bit he will be blameless if the owner did not allow him to do his work independently

NextD18:

Possibly, the column base, perfectly required rods, thickness of casting, foundation walls and other structural activities in the foundation were properly done.

How about the soil test where the strength of soil should be checked? That's what many builders overlook before building.

They just assume judging with the nearby buildings, next is site preparation, do their setting out and booom, they don start foundation.

Checking of soil properties is major problem in Nigeria..some just pay a technologist to form soil results for them without doing proper soil tests.

Second posted picture of the building with buses parked in the front is not a true picture of the collapsed building but another building near Concorde hotel. If the aim of the poster is to link it to the collapsed one, it is rather very unfortunate.

The contractor is very much at fault if proper investigation is carried out, I know this building very well, the very first day I saw it while traveling from Edo State to Port Harcourt due to the number of workers I saw there this thought came to my mind, he was managing everything in his possession.
