Nigerian engineers have said that a building in Lagos which collapsed while under construction killing 45 people was more than three times higher than originally designed.
The Nigerian Institution of Structural Engineers said there were also signs that more than two engineering firms were working on the project at the same time.
The Nigerian government is carrying out its own inquiry into the collapse of the 21-storey apartment block earlier this month in the upmarket Ikoyi district.
The owner of the building was among those who died.
