The Central Building Research Institute (CBRI), Roorkee began 3D laser scanning of the Taj Mahal on Sunday. The aim of the exercise is to carry out structural investigation about the strength of the monument, including its tomb structure and minarets.
The institute is acting on the orders of the Supreme Court.
The eight member team arrived in the city on Sunday. They collected data such as the angles the minarets made with respect to its platform.
The survey will continue till January 22. It would resume after the visit of US President Barack Obama.
During the month-long survey, the CBRI team would collect data on every aspect related to threats to the world heritage site. As per the report, necessary steps would be undertaken to strengthen the structure.
Laser scanning is a certified technology and the report is likely to reveal many things about Taj Mahal, said NK Pathak, superintendent archaeologist, Archaeological Survey of India.
