Chennai Corporation will use fibre wrap technology to fortify its old civic structures, including buildings and bridges, against earthquakes.

The fortification techniques have been initiated in the wake of the city being upgraded to seismic zone III a few years ago. Work on Kodambakkam Bridge and Ripon Buildings has already started. Other major old buildings that are weak will be identified for fibre wrapping shortly.

“Over 1500 sq m of fibre wrap is being used for strengthening columns of the ground floor of Ripon Buildings. This will strengthen the columns that are likely to be damaged during seismic events,” said an official of Chennai Corporation.

“The fibre wrap being used now is blue in colour, and is capable of withstanding extremes of temperature. It is also cheaper than other available technologies. The fibre wrap is wound around the columns and the original material (lime mortar or cement) will then be packed on top of it.

Workers at Ripon Buildings are using safety goggles, chemical resistant gloves and particle masks during the restoration project, funded by Jawaharlal Nehru National Urban Renewal Mission. Other old buildings and bridges will be restored in a similar manner as part of disaster preparedness of the Chennai Corporation.

The civic body has also done fibre wrapping on the columns Kodambakkam bridge as part of restoration of the 50-year-old structure. The restoration would include spraying of anti-corrosion material and grouting. A few years ago, an expert study conducted on the 623-metre-long and 12.8-metre-wide structure concluded that it had weakened.

Every year, the Chennai Corporation prepares a list of weak structures as part of disaster preparedness and also draws plans to evacuate people near the structure in case of calamity. Some of the Corporation’s office, residential and commercial buildings too have been declared weak.

Besides, women working at the nearby BSNL office had submitted a petition demanding a separate bus stop for them.

After the nod from the transport officials, all government buses will now stop at the Vellore Corporation office bus stop from Friday, Karthiyayini informed.

Empty Classrooms Bring Shutters Down on 62 Corporation Schools: Survey

Empty Classrooms Bring Shutters Down on 62 Corporation Schools: Survey

A new survey in Chennai has revealed that 62 Corporation schools have been closed down in the last one year. The survey on Status of Closure of Government Schools in Tamil Nadu, which was carried out by Child Rights and You (CRY), found that even as private schools are mushrooming in the city, the number of corporation schools is going down.

The survey was conducted over a period of one year by CRY in association with NGOs under the Sama Kalvi Iyyakam - Tamil Nadu. The survey pointed out that several neighbourhood schools, especially primary and middle schools, were shut down in the past one year.

“A total of 62 schools were shut down in the last one year, according to our survey. The significant point is that the government refuses to use the word ‘shut down’ and instead says that the schools have been ‘upgraded’. This effectively means that if there are two lower level schools like a primary or a middle school, then one of them would be upgraded to a higher level like high school or higher secondary school, while the other school would be shut down. The school which is shut down would  be called ‘upgraded’ even as the school building is shut down,” said Sarah Ramya, manager, CRY-Tamil Nadu.

However, officials of the Chennai Corporation have denied any such move. “In the past two years, we have not shut down any school,” said a senior official with the Education Department of the Chennai Corporation.

The Corporation had earlier in the year discussed the possibility of merging schools, which have low enrollments. In fact, 56 schools have been merged between 1999-2011.

According to the Corporation officials, such mergers help in concentrating resources on well-functioning schools.

But education activists say that absence of schools in the neighbourhood is one of the main reasons for dropouts and child labour.

An earlier survey by CRY had pointed out that in areas like North Chennai, children lose interest in going to school when they have to walk for 2-3 kilometres. This, coupled with the economic pressure, results in dropouts and child labour.

Others argue that the answer to lack of enrolment in government schools should be overcome by enhancing the quality and infrastructure rather than shutting down the schools.

“The reason why parents are not sending their children to these schools is lack of quality. Many have one teacher to teach multiple classes and subjects. There are no proper sanitation facilities and in the absence of staff to perform cleaning, office duty, etc., the teacher is forced to take her time off from the classes and attend to these. So, the Corporation has the responsibility to improve this condition. Instead they shut down the schools,” said P B Prince Gajendra Babu, general secretary of the State Platform for Common School System.
