Reason Behind The Building Collapse In Ibadan
There are indications that the site engineer in charge of the three-story building that collapsed last Friday evening at Shogoye area of Idi-Arere, Ibadan, will be deregistered by the Council for the Regulation of Engineering in Nigeria (COREN).
This especially as the Oyo State government today, declared that he had run away, having refused to show up to explain in writing the cause of the tragedy.
The Director-General, Bureau of Physical Planning and Development Control in the state, Alhaji Waheed Gbadamosi, disclosed this in a telephone interview with Sun in Ibadan.
He stated that the government on Monday this week, summoned the site engineer of the collapsed Asfau-Aqhi building but he refused to honour the invitation.
Gbadamosi said the option left for the government “is that we will officially report him to the Council for the Regulation of Engineering in Nigeria (COREN).”
The three-storey building had collapsed at 5:34 p.m last Friday and all the trapped site workers were rescued alive; those of them that sustained varying degrees of injury were hospitalized.
Gbadamosi noted that the preliminary reports on the possible cause of the disaster revealed that standard materials were used for the construction, but “we have found out that they did not allow the curing period to lapse before they continued with the construction.
“When you do your decking, you must allow it to cure for 21 days before you start to put blocks on it. But they did not allow the three weeks to lapse. I think they were in a hurry to complete the building.
He stated further that the government has always been ensuring that “any developer comes with his or her own engineer. The engineer will sign an undertaking with us with COREN stamp to undertake the supervision of any structure from foundation till completion.”
Gbadamosi stated that the site engineer signed an undertaking with the Bureau of Physical Planning and Development Control, that he would supervise the collapsed building from foundation till completion, saying a certificate of completion should have been issued when the project was completed.
“When you complete your building, you must come back to tell us. Then, we will go and examine whether you are worthy of being given what we call a certificate of completion. You will pay a token, like N25,000 before we give you that. If we don’t give you the certificate of completion, it means the building is not worthy of being inhabited by any individual, not even goats.”
However, the site manager, Mr. Abdulmojeed Tijani, said he observed that the columns in the collapsed building were not big enough; they were of smaller sizes.
According to Tijani, there was no column to support the concrete in the middle, adding that the concrete “was not allowed to dry enough before moulding on it. Moulding, he said, should have started from the base floor, and not the top floor.
He said he made the discovery last Friday and he wrote an official letter to be presented to the Bureau of Physical Planning and Development Control the following Monday, adding that the building collapsed the same day he made the discovery. He noted that he opted to make the report to the bureau because the site engineer would not be under any obligation to respect his view on the project.
