NOC Survey for the construction of high-rise buildings

We GCPL, are Airport’s Authority of India’s (AAI) empanelled survey agency. We undertake survey for obtaining NOC for height clearance from AAI / IAF, for constructing high raised buildings and skyscrapers.

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. In case of defence airport, the application is submitted to the concerned defence authority.

We do continue followup with the concerned authorities and assist the applicant to obtain the NOC. Thus we undertake the complete Liasioning for obtaining NOC for height clearance.

Thus in turn we assist in avoiding future obstacles to ensure a safe airspace.

We undertake NOC Appeal Cases

If any person or Local, Municipal or Town Planning and Development authorities
or any airport operator is aggrieved with the decision of the Designated officer,
such person or entity may appeal to the Appellate Committee for redressal of
his/their grievances with respect to the height permissible in Govt. notification
GSR 751(E) as amended by GSR 770(E)

We help in Documentation required for NOC Appeal Cases and Apply for Aeronautical Study if required.

NOC for Construction of Power Projects /WTGs/Solar Power projects

As per the Guidelines NOC for Construction of Power Projects/Wind Turbine Generators/Solar Power Projects (except solar power modules at the top of building for domestic usage) is required to be obtain from Ministry of Defence.

The NOC is proposed by various government agencies /autonomous bodies for Power projects and also by private agencies/individuals for private Power Projects . As per the existing procedure, applications for grant of NoC are forwarded by stakeholders ministry/organization to Ministry of Defence (MoD) for their recommendations. Bases on the inputs of the concerned authorities, the Ministry of Defence decides upon grant/refusal of NoC for such Power Projects.

The newly developed MoD web portal is aimed at facilitating the vendors for submission of applications online for grant of No Objection Certificate for Construction of Power Projects/Wind Turbine Generators/Solar Power Projects (except solar power modules at the top of building for domestic usage) . The automated/online system will help in reducing the time, bringing in more transparency, accuracy and speedy disposal of applications for grant of NoC by MoD . The latitude/ longitude for each of application should be clearly mentioned in application for ease in locating the items on ground.

Airport Feasibility Survey & Analysis

GCPL has the expertise in doing airport feasibility survey and analysis, for a green field, brown field airport. The proposed area with proposed runway orientation is studied with the OLS and an obstacle survey is conducted to accurately check the best location of the proposed runway. This is done with the help ESRI’s GIS software and our inhouse developed software.

Topographic Survey

A Topographic Survey is a survey that gathers data about the elevation of points on a piece of land and presents them as contour lines on a plot. The purpose of a topographic survey is to collect survey data about the natural and man-made features of the land, as well as its elevations. Topographic maps are used to show elevations and grading features for architects, engineers, and building contractors.

Applications of GIS in Real World

3D Scanning and Modeling

Working on a project requiring a 3D scanning? We’re there for you! Whether you need building scanning, we’re proud to offer all of our services to accommodate your needs no matter where your project is located.

A laser scanner will always produce a point cloud from which a 3D-model can be created should such be required. Both the point cloud and the 3D-model are georeferenced and to scale, making it possible to collect accurate measurements from within them. Point clouds are well suited to visualization and further processing, and can be delivered in LAS, PTS, or XYZ formats. The point clouds may contain intensity values or color values to create a more realistic visualization, if desired.

The point cloud is used to create a 3D-model, with the desired detail and BIM levels. This can be anything from large, rough constructions such as tunnel contours to small details like wall / façade decorations. Metadata can be attached to the digital objects, such as pipe type, manufacturer, feature code, post number, infrastructure type, and much, much more.

This makes the data very well suited for further processing in a BIM, CAD or GIS environment such as Revit, AutoCad or ArcGIS. Many modern tools provide the possibility of working with the information within this type of 3D-models, as well as using point clouds for visualization.

We have created 3D Model of Terminal Building T1D at Indira Gandhi International Airport. This will help L&T to construct cloning of Terminal Building.
