Swami Vivekananda Airport occupies an unusual position for an Indian airport. Rather than sitting at the edge of a single city, it sits almost exactly between two: the old city of Raipur and Naya Raipur, Chhattisgarh’s planned new capital. That means projects in both urban centers, not just one, need to be checked against the same regulated zone.
This page covers what an Airport NOC survey Raipur project actually needs. That includes a certified GPS and AMSL survey, Obstacle Limitation Surfaces (OLS) analysis, and full NOCAS filing support, whether your project sits in the older parts of Raipur or in the rapidly developing Naya Raipur corridor.
Why Raipur’s Airport Location Affects Two Cities at Once
Swami Vivekananda Airport sits at Mana, roughly 15 km southeast of Raipur’s old city center and about 10 km east of Naya Raipur. The airport was renamed in 2012 after previously being known as Mana Airport, and it sits at a surveyed elevation of about 317 metres AMSL.
This central position between the two cities means the airport’s 20 km regulated radius reaches deep into both. Naya Raipur, developed as India’s second planned capital city after Chandigarh, has been growing rapidly with new government buildings, institutional campuses, and residential sectors. Many of these projects sit closer to the airport than developers initially assume, simply because the city was planned around infrastructure corridors that overlap with the airport’s zone.
How AAI Calculates Permitted Height Around Raipur
AAI’s height math in Raipur follows the same national formula used across every Colour Coded Zoning Map in the country. Permitted height of the structure equals the CCZM’s permitted top elevation, minus your site’s verified ground elevation, both measured in metres AMSL.
Where a CCZM has been issued for the airport, local municipal and development bodies can approve proposals requesting a top elevation below that threshold without referring the case to AAI. This delegation has a ceiling, though. The maximum elevation approvable through CCZM alone is 150 metres. Anything above that figure needs a formal application through AAI’s NOCAS portal.
Given that both Raipur Municipal Corporation and the Naya Raipur Development Authority oversee construction in this metropolitan region, confirming which body handles your specific approval, alongside the airport height requirement, is worth doing early.
Why OLS Analysis Matters for Every Application
Obstacle Limitation Surfaces, or OLS, define the three-dimensional airspace envelope AAI protects around every runway. This isn’t a flat citywide height cap. It’s a series of sloped and level surfaces that vary by your exact distance and bearing from the runway.
A proper OLS analysis checks your specific plot against these surfaces, rather than relying on a rough distance-based guess. Nationally, roughly 40% of height clearance NOC applications get rejected by AAI, and a large share of those rejections trace back to inaccurate elevation or coordinate data rather than genuinely excessive proposed height. Getting this analysis right before submission matters just as much for a government building in Naya Raipur as it does for a residential tower in old Raipur.
Do You Need an AAI NOC for Your Raipur Project?
Under the GSR 751(E) rules that govern height clearance nationwide, any structure within 20 km of the airport’s Aerodrome Reference Point needs to be checked against the applicable restriction. This requirement holds regardless of the structure’s height or intended use.
Whether you need a full formal NOCAS application depends on where your surveyed elevation falls relative to the CCZM’s permitted top elevation for your specific grid cell. If you’re seeking a separate aviation-related clearance, such as for drone operations, remember that an AAI height NOC and DGCA clearance serve different purposes and neither substitutes for the other.
How an Airport NOC Survey Works in Raipur
- Zone and OLS check — Confirm your plot’s distance and bearing from the airport’s Aerodrome Reference Point, and check the current permitted top elevation for your grid cell against the Obstacle Limitation Surfaces.
- Site elevation and coordinate survey — A site elevation survey captures WGS-84 coordinates and AMSL elevation for your plot using certified GPS equipment, meeting AAI’s accuracy requirements.
- Height verification — We check your proposed structure’s top elevation, including rooftop additions like water tanks and lift motor rooms, against the CCZM’s permitted top elevation for that grid.
- Documentation — We compile certificates, ownership proof, and structure drawings per AAI’s NOCAS documentation requirements, cross-checked against the current list of documents required for airport height clearance.
- Filing or auto-settlement — Depending on whether the structure exceeds the CCZM threshold, we either route the case through the relevant local body, file formally through the NOCAS portal application process, or let the system auto-settle it.
Which Projects in Raipur Need This
This requirement extends well beyond residential towers. It applies to:
- Building height clearance for residential and commercial construction anywhere within 20 km of the airport, in both old Raipur and Naya Raipur
- Government, institutional, and campus buildings in Naya Raipur’s planned sectors, given the scale of ongoing development there
- Solar and wind or hybrid renewable installations planned in the outer growth corridors around Mana
Swami Vivekananda Airport also operates as a standard civil airport under AAI, without the added defence-jurisdiction complexity you’d encounter in a city like Pune, keeping the underlying process straightforward even with two cities to account for.
How Long Does an Airport NOC Take in Raipur?
Field survey work for a single plot typically takes a few days. Certified documentation is usually ready within two to three weeks after that.
AAI’s own review time through NOCAS depends on case load and on whether your site falls above or below the local CCZM threshold. Applications routed through a local body tend to move faster than those requiring full AAI review.
Given the pace of development in Naya Raipur, it’s worth checking your zone status early in the planning process rather than after a layout has already been finalised.
Why Get Your Raipur Airport NOC Survey Done by Surveying India
Our in-house DGPS and Total Station teams deliver certified GPS coordinates and AMSL elevation to AAI’s exact accuracy requirements across old Raipur, Mana, and the Naya Raipur development corridor. We run a full OLS analysis for every application, rather than relying on a rough distance estimate, which is where most avoidable rejections happen.
Because we prepare documentation to AAI’s exact NOCAS format, we cut down the remarks and resubmissions that stall projects, whether they fall under Raipur Municipal Corporation or the Naya Raipur Development Authority. We also confirm whether your project qualifies for faster local-body approval under the CCZM before defaulting to a full AAI filing.
Beyond Raipur, we’ve delivered survey work for government bodies, PSUs, and private developers across airport-regulated zones in India for over a decade. Our teams also work in Patna, Indore, Nagpur, Pune, Mumbai, Bengaluru, Delhi NCR, Varanasi, Jaipur, Lucknow, Chandigarh, Ahmedabad, Kota, and Bhopal.

Frequently Asked Questions
Why does Raipur’s airport location matter for both old Raipur and Naya Raipur? Swami Vivekananda Airport sits at Mana, roughly midway between old Raipur and Naya Raipur, about 15 km from one and 10 km from the other. Its 20 km regulated radius reaches into both urban centers, so projects in either city need to check the same zoning requirement.
What is the maximum height a local body can approve without referring to AAI? Up to 150 metres of top elevation can be approved through the CCZM by local municipal or development bodies directly. Any proposed elevation above that figure requires formal review through AAI’s NOCAS portal.
What is OLS analysis, and why does it matter for my project? Obstacle Limitation Surfaces define the three-dimensional airspace envelope AAI protects around a runway. A proper OLS analysis checks your exact plot against these surfaces, which is more reliable than assuming clearance based on distance alone.
Does every construction project in Raipur or Naya Raipur need a full AAI NOC application? No. If your proposed structure’s top elevation is below the CCZM’s permitted top elevation for your grid cell, and that elevation is under 150 metres, your local body can approve it directly without a full AAI filing.
Which authority handles building approval in Naya Raipur? The Naya Raipur Development Authority (sometimes referred to as Nava Raipur Atal Nagar Vikas Pradhikaran) oversees construction approvals in the planned city, separate from Raipur Municipal Corporation, which handles the older part of the city.
Is Raipur’s NOC process complicated by any defence airbase? No. Swami Vivekananda Airport is a standard civil airport owned and operated by AAI, so Raipur’s NOC process runs through the usual civil route without an additional defence clearance requirement.
Regulatory reference: Height clearance rules near Raipur’s airport fall under Gazette Notification GSR 751(E). Zoning data and the CCZM are maintained by the Airports Authority of India on the official AAI NOCAS portal. Always verify the current PTE and zone classification for your specific coordinates before finalising a project.
