Construction industry is all set for major changes. The revised National Building Code 2005, which has just been released, sets new standards for construction of buildings and other infrastructure. The NBC 2005, formulated by the Bureau of Indian Standards, spells out new regulations for adoption by infrastructure departments, municipal administrators, public bodies and private agencies. Aspects such as rainwater harvesting and landscaping are covered. The relevant provisions for earthquake resistance are amended following the changes in the seismic zone maps for the country. A.R. Shanthakumar, Emeritus Professor, IIT-Madras, and an expert in structural engineering, says the NBC is now a national instrument that will guide the regulations for construction activity.
