Big Infrastructure Projects in India That Need GPR Survey

Which infrastructure projects in India need GPR or SUE survey?

The big projects that need GPR or SUE survey are the ones that dig, pile or bore through ground already full of services. That covers high-speed and freight rail, metro phases, expressways, airports, the gas grid and the national fibre, power and water programmes. Ground penetrating radar, which images buried pipes and cables from reflected radio pulses, finds those underground utilities before design is frozen and again before excavation starts.

The list below is our working view of where that demand comes from, with each project’s stage as published by its owner or reported by a named news source. Status lines are as of 8 November 2026 and we refresh them every month. A project appearing here does not mean we work on it; it means its scope involves the ground investigation we carry out. The table also serves as a watch-list of upcoming infrastructure projects India will tender in the next few years.

Read the stage column with care. “Open” seldom means finished for survey purposes. Later phases, depots, feeder roads and service connections keep digging for years after the ribbon is cut. “DPR stage” is the best time to bring in a utility survey, because a clash found on paper costs a drawing revision, not a diversion.

Table note: freight corridor feeder and crossing work has its own checklist – see when you need a DFCCIL utility survey.

Where do the bullet train, freight corridors and RRTS stand?

The bullet train is the large live rail job; the two freight corridors are finished, so the survey work there has moved to feeders and new corridors.

• Mumbai–Ahmedabad High Speed Rail: of the 508 km route, 371 km of viaduct and 456 km of pier work were complete by September 2026. Excavation of four mountain tunnels in Maharashtra is done. The corridor has 12 stations, and the Railway Minister has said the first 100 km run between Surat and Vapi will take place in August 2027.¹ Station precincts and approach roads are where buried services collide with the work.
• Western Dedicated Freight Corridor: the final 102 km, JNPT to New Saphale, completed its trial run on 31 March 2026, finishing the corridor.² The Western DFC is 1,506 km from Dadri to JNPT; the Eastern DFC, 1,337 km from Ludhiana to Sonnagar, was completed in October 2023.^3,4
• New freight corridors: three more are under examination with detailed project reports in progress: East Coast (Kharagpur–Vijayawada), East–West and a North–South sub-corridor.³ DPR-stage surveys are the cheapest time to record buried crossings.
• Delhi–Meerut Namo Bharat RRTS: the full 82 km from Sarai Kale Khan to Modipuram was inaugurated on 22 February 2026, with Meerut Metro sharing 23 km of the track.⁵

On a viaduct project the main line itself is in the air, but every pier foundation, casting yard, access road and station forecourt is dug at ground level. A pier located over an unrecorded water main or telecom duct has to be shifted or the service diverted, and both are slower once the piling rig is on site. Scanning the pier grid and approach roads before mobilisation costs far less than either and helps avoid accidental utility strikes.

For rail clients the survey asks are similar from job to job: crossings under the track, cables along the formation and services in station yards. We set these out on our page on railway projects.

Which metro phases are digging in Indian cities?

Delhi, Chennai and Bengaluru all have large sections under construction in 2026, and Mumbai finished its first fully underground line in 2025. Metro work is the densest utility environment in the country: station boxes and piling sit on top of water mains, sewers, power cables and telecom ducts.

• Delhi Metro Phase 4: Janakpuri West–Krishna Park Extension opened in January 2025 and Majlis Park–Maujpur in March 2026. Krishna Park Extension–RK Ashram Marg and Tughlakabad–Aerocity were targeted for December 2026; three more corridors are expected around 2029. Phase 5(A), including RK Ashram Marg–Indraprastha and Aerocity–IGD Airport T-1, is targeted for 2028.⁶
• Mumbai Metro Line 3: the 33.5 km Cuffe Parade–Aarey JVLR line became fully operational on 9 October 2025 as the city’s first fully underground corridor.⁷
• Chennai Metro Phase II: the 118.9 km programme across corridors III, IV and V has 128 stations, mostly underground. Its first 14.64 km stretch, Poonamallee–Vadapalani with 11 elevated stations, was inaugurated on 11 October 2026.⁸
• Bengaluru: in August 2026 BMRCL was targeting the 7.5 km elevated Pink Line section from Kalena Agrahara to Tavarekere for opening on 15 August, subject to safety approvals. The 13.76 km underground section to Nagawara was targeted for March 2027, and the airport section of the 58 km Blue Line for December 2027.⁹ The August date slipped: the metro safety commissioner cleared the elevated section on 28 October 2026.²⁴

The usual sequence on a metro contract is survey, diversion design, diversion work and then the main excavation. If the first step misses a line, the error surfaces in the last one, often as a burst main or a cut cable in a crowded street. Underground stations raise the stakes because the excavation is deep and wide. Services crossing the box have to be supported, or a utility relocation agreed, before the walls go in.

Most metro survey briefs ask for the same three things: a utility map of each station footprint, a diversion plan and confirmation pits. More detail is on our page on metro rail projects.

What about the fibre, power and water programmes?

Three national programmes – BharatNet, RDSS and Jal Jeevan Mission, with AMRUT 2.0 in towns – put new lines into the same road edges, which is where strikes happen.

Amended BharatNet

The Union Cabinet approved the Amended BharatNet Program on 4 August 2023 to take connectivity to about 2.64 lakh gram panchayats and, on demand, about 3.8 lakh villages. It moves to an IP-MPLS ring architecture, with BSNL as project management agency and implementation agencies chosen across 16 packages.¹⁰ The task is large. A parliamentary committee report tabled in August 2026 said only 78,899 gram panchayats, about 30%, had operational points of presence as of 28 February 2026. It put the amended programme’s outlay at about ₹1.39 lakh crore.¹¹ Ring routes mean new fibre along roads that already carry older cable. Before quoting, work through the questions to ask before a BharatNet route survey.

RDSS

The Revamped Distribution Sector Scheme was launched in July 2021 with a total cost of ₹3,03,758 crore and has been extended to 31 March 2028.¹³ A Lok Sabha reply in February 2026 said distribution infrastructure works worth ₹1.53 lakh crore had been sanctioned and listed underground cabling among them, mandated in coastal areas.¹⁴ New HT and LT cables in built-up streets need the existing cable, gas and water lines found first.

Jal Jeevan Mission and AMRUT 2.0

On 10 March 2026 the Cabinet extended Jal Jeevan Mission to December 2028 with a total outlay of ₹8.69 lakh crore. About 15.80 crore of 19.36 crore rural households had tap connections at that point, and a new “Sujalam Bharat” framework will map each village’s supply system from source to tap.¹² In towns, AMRUT 2.0 had approved 3,528 water supply projects covering about 1,26,000 km of network and 583 sewerage projects by 9 February 2026.¹⁵ Mapping old pipes before laying new ones is the quiet half of this work.

Rural pipelines bring their own difficulty. Many village lines are PVC or HDPE laid at shallow depth with no utility records of the route. A metal locator cannot see them, so GPR does the main detection work. Soil type decides how deep it can see: dry sandy ground gives clear signals, while wet clay shortens the useful depth. Where the scan is uncertain, a trial pit settles the question.

Which roads, airports and gas projects are worth watching?

The Delhi–Mumbai Expressway, the two new Mumbai and NCR airports and the gas grid all have work still to come after their headline openings.

• Delhi–Mumbai Expressway: the project scope is 1,445 km including spurs; 929 km was operational in March 2026. The last gap in the Delhi–Vadodara section was expected to close in December 2026 or January 2027, and the slowest southern packages are expected by March 2028.¹⁶
• Navi Mumbai International Airport: inaugurated by the Prime Minister on 8 October 2025, it began commercial flights on 25 December 2025. Phase one handles 20 million passengers a year, and five phases are planned up to 90 million.¹⁷
• Noida International Airport, Jewar: commercial flights began on 15 June 2026 with one runway and one terminal for about 1.2 crore passengers a year. The long-term plan is more than 7 crore.^18,19
• National Gas Grid and city gas: as on 31 March 2026, 27,905 km of natural gas pipeline was in operation and 8,551 km under construction. There were 307 authorised city gas distribution areas and 1.69 crore domestic PNG connections.²⁰ Every new city gas main is laid beside services that were there first.

On expressways the survey need sits at interchanges, toll plazas, wayside amenities and every point where the new road crosses an older one carrying cables and pipes. Utility shifting there is planned well before the carriageway is built, and the shifting plan is only as good as the survey behind it.

Airports bring their own mix of airside cables, fuel lines and drainage. In each case the remaining phases, not the opening day, are where most of the survey work lies.

How do PM Gati Shakti and the end of Smart Cities change things?

Gati Shakti is pushing utility data into a shared GIS, while the Smart Cities Mission is over, so new city-level demand now comes through other schemes.

PM GatiShakti National Master Plan was launched on 13 October 2021. By October 2026 it held more than 1,800 data layers from 58 central ministries and departments and covered all 36 states and union territories. It had been used to evaluate over 400 projects worth more than ₹20 lakh crore.²¹ In March 2026 the Centre told Parliament it had asked states, union territories and central infrastructure ministries to map their underground utility assets on the Master Plan platform.²² That request turns survey output into a long-lasting asset: a geo-referenced layer of utility maps the next planner can open. It is also why we deliver results through CAD and GIS utility mapping, not paper sketches.

The Smart Cities Mission, launched in 2015, reached its deadline on 31 March 2025. Its dashboard showed 7,491 projects completed and 567 still ongoing as of February 2025.²³ Anyone still chasing “smart city” tenders should look instead at AMRUT 2.0, metro and city gas work, where the digging continues.

How should a big project plan its utility survey?

Survey early, at the right quality level, and in the coordinate system the designers use. A GPR survey for infrastructure projects India-wide works best when it starts at the DPR stage, because the order of work matters as much as the instrument.

1. Desk study: collect existing records from owners, CBuD responses and any Gati Shakti layers for the corridor.
2. Set the quality level: SUE practice separates records-only information from surface-traced, geophysically located and exposed utilities. If the owner asks for quality levels A to D, read: SUE survey for how we deliver each.
3. Field scan: GPR plus electromagnetic location along the alignment, with L-sections at crossings.
4. Confirm: trial pits at the crossings that drive design decisions.
5. Deliver: drawings and GIS files that slot into the project’s own model.

What should the deliverable look like? For a corridor, we provide a utility layout drawing in the project’s coordinate system and chainage-wise tables of every detected line with approximate depth. L-sections at major crossings and GIS files for the client’s platform complete the set. A civil engineering designer can then check clashes without reopening the field data, and the same information feeds a Gati Shakti layer.

Our GPR rates are ₹24 per metre standard and ₹32 per metre with an L-section, GST extra. The minimum order is ₹50,000 in Delhi NCR and ₹1,00,000 elsewhere in India. Long corridors earn whole-order discounts of 25% above 100 km, 40% above 500 km and 50% above 1,000 km. With 58 company-owned GPR systems and our own crews, we do not sub-let survey work. Send the alignment and you can get a quick estimate.

Frequently asked questions

Which infrastructure projects in India need the most utility survey right now?

Metro phases in Delhi, Chennai and Bengaluru, the Mumbai–Ahmedabad bullet train, BharatNet ring routes, RDSS cabling and city gas laying, because they all dig in ground that already holds services.

Is the Smart Cities Mission still running?

No. Its deadline was 31 March 2025. New urban digging now comes mainly through AMRUT 2.0, metro projects and city gas distribution.

When is a GPR survey most useful on a large project?

At the DPR or design stage, when a clash can be designed out cheaply, and again before excavation to confirm what lies there.

Do airports need a separate type of utility survey?

They need tighter coordination with airside rules and more cable and fuel-line detail. We list the questions to ask before an airport utility survey.

How often is this project list updated?

Every month. For weekly project and utility-strike news, see the Mezux guide: GPR & Infra News from Mezux Touch.

Can you survey a full corridor of several hundred kilometres?

Yes. Long routes are priced per metre with whole-order discounts of 25%, 40% and 50% above 100, 500 and 1,000 km, and we run them with our own crews.
