The illegal Mumbra building, which collapsed in April claiming 74 lives, was built dangerously, states the Central Building Research Institute’s report, which is part of the charge sheet that was submitted before court by the police on Monday.
The Uttarakhand-based institute’s preliminary report is an important piece of evidence submitted by the Thane crime branch, which is investigating the mishap.
In the course of investigation, the police have charged 22 persons for the collapse, including the builders, senior civic officials, the architect and a corporator.
“The builder had constructed one floor in one week. This is dangerous because concrete aged for just one week had to bear the load of another floor.
In addition, it had to bear the load of the labourers and the construction materials,” the report states.
The report was prepared after Dr B Kameshwara Rao, chief scientist and advisor, structural engineering division, CBRI, inspected the site at Mumbra’s Lucky Compound.
“The builder did not adopt proper foundation system and reinforcement detailing.” observed the report.
“The builder did not use concrete mix and there was no use of proper structural design.”
During their three-day site inspection, Dr Rao and his team collected samples of the materials used to construct the seven-storeyed structure and soil for further tests.
“The team will submit a detailed report that we will present before court. The findings will be helpful,” said a senior officer, requesting anonymity.
For further corroboration that the building collapsed because of poor construction, the police have roped in the Indian Institute of Technology Bombay, the public works department and the Forensic Sciences Laboratory, whose reports they are awaiting and which will be submitted in court.
“We have enough scientific and technical evidence to make it a watertight case. The contractors did not have the academic background to construct a building. We believe that all the accused were aware of the consequences of building such a structure,” the officer said.
