Conduct Structural Audit Of Tower A Again, Town Planner Tells Chintels, ET RealEstate

June 23, 2023

GURUGRAM: The department of town and country planning (DTCP) has directed the developer of Chintels Paradiso to get another structural audit of tower A of the Sector 109 society conducted by another agency, preferably the Central Building Research Institute (CBRI), within 30 days.

IIT-Delhi had earlier carried out an audit of the tower. In its report, made public earlier this month, the institute declared it safe for now, but also said deterioration has been noticed. It recommended a structural audit annually to ensure safety of residents.

According to the DTCP order, which was issued recently, the developer — Chintels India — has to submit a compliance report within 30 days and execute the report’s recommendation. The department also directed Chintels to get another tower, tower G, vacated and submit a report to the district administration.

“The second structural audit of tower A is to suggest rehabilitation measures so that the effect of corrosion can be counterbalanced and the structure saved from any further structural damage. It will be the builder’s responsibility to get the required arrangements done. If this is feasible, then the builder shall be mandated to follow the instructions of the agency and get the outcome certified from it,” the order stated.

A DTCP official said, “If the conclusion of the agency remains the same as that of IIT-Delhi, which is that the building is safe at present but is bound to deteriorate due to high chloride content in concrete and it is not technically feasible to rehabilitate it, then the builder shall conduct structural audits of tower A every January through one of the four consultants empanelled by the administration.”

The order further directed the builder to share the structural audit report with the RWA as well as DTCP. In case of an adverse structure audit report, the builder shall compensate the owners in the same way as towers D, E and F, the official added.

For tower G, which has been declared unsafe for human inhabitation by IIT-Delhi, the deputy commissioner had on June 12 issued an order under the Disaster Management Act directing those residing in tower G to vacate their premises and hand over possession to the developer within 15 days.

In the recent order, DTCP also directed Chintels to ensure that tower G is vacated and a compliance report submitted to the deputy commissioner. “The needful must be done in the prescribed time limit. For any lapse, the developer will be deemed responsible and legal action will be taken,” it said.

A vertical cave-in of five flats in the society in February 2022 led to the death of two residents. Since then, that tower, ‘D’, has been abandoned and three more have been declared unfit for habitation.

According to the IIT-Delhi report, there is a rapid and widespread corrosion of reinforcement almost throughout the structure of tower A. “This corrosion is due to chlorides that were mixed into the concrete at the time of its production. The need for frequent repair in the structures as has been reported by residents also appears to have been caused by corrosion of steel reinforcement. Due to the presence of these chlorides, the poor quality of concrete has also played a role in the rapid deterioration given the high chloride content in the concrete. Repair of these structures for safe usage is not technically and economically feasible in the current condition… the structure is not fit for habitation,” the report stated.
