NOC Survey for the construction of high-rise buildings

For high-raised structures, such as buildings, masts, chimney and billboard etc. is around an existing or a proposed airport, an NOC from the AAI and/or defence authority (if it is a defence airport) is imperative.
Airports Authority of India has introduced NOCAS, NO Objection Certificate Application System, to accept online applications for height clearance for the structures for Safeguarding the Airspace in and around the civil airports as per the rules laid down in GSR 751 (E), issued by MoCA on 30th September, 2015.
For the Defence Airports, responsibility is with the respective Defence Authorities.
We do an AMSL/RL survey with the help of DGPS and Total Station. The required Airport zoning map locating the proposed construction site is prepared by us. This map along with other drawings such as, site layout drawing, building elevation plan and other mandatory documents are obtained from the customer and the application is submitted to AAI, through AAI’s official web portal.
