Utility Survey for Industrial Corridors and New Cities

What does a utility survey for industrial corridors check?

It checks two layers at once: the old services in the ground before the new city was planned, and the trunk networks the developer has laid since. Both can conflict with what comes next, whether that is a further phase of trunk infrastructure, a plot connection or a large factory foundation.

Corridor projects move fast and in parallel. Different contractors often build the road, water, power, sewer, gas and telecom packages at the same time. The as-built drawing for one package may not show what the next contractor laid beside it. A survey gives every party the same picture of the underground utilities.

Why does greenfield land still hide buried services?

Because "greenfield" means farmland and villages, and farmland carries its own network of pipes, cables and channels that never appear on an urban utility drawing. Typical finds on corridor land include:

• Irrigation lines and borewell pipes crossing fields, often of plastic and only a short depth down.
• Village water supply mains along the old roads that the new grid now cuts across.
• Rural power and telecom cables serving pump sets, schools and mobile towers.
• Old cross-country pipelines for gas or petroleum products, with their own right of way and operator.
• Canal syphons, culverts and field drains, some disused and silted, some still carrying water in the monsoon.

Greenfield utility mapping finds these before the first trunk trench is cut, when moving a road or a pipe is still cheap. Ground penetrating radar (GPR) is the main geophysical survey tool here. Its pulses travel into the soil as electromagnetic waves, and a plastic irrigation pipe or old culvert returns a clear echo in dry ground.

Dholera, AURIC and the other corridor nodes

The Delhi–Mumbai Industrial Corridor and the other national corridors are being developed through new industrial cities and nodes, each with a planned network of underground services. The National Industrial Corridor Development Corporation (NICDC) leads the programme with state partners. Two of the best-known nodes are the Dholera Special Investment Region in Gujarat and AURIC, the Aurangabad Industrial City at Shendra–Bidkin near Chhatrapati Sambhajinagar in Maharashtra.

These cities are built around common utility corridors and ducts along main roads, so services can be added without repeated digging. The survey of those corridors, and of what sits beside them, is a discipline of its own; our page on utility corridor mapping covers how we do it. At Dholera the land is flat and low-lying near the Gulf of Khambhat. Moist clay soils there can limit radar depth, so locators and marker-post checks carry more of the load.

NICDC, corridor special purpose vehicles and state industrial development corporations have commissioned GPR work from Mezux Touch directly. Node contractors, consultants and plot holders make up the rest of our work there.

What should a plot holder check before building?

Before a footing is dug, a plot holder should know where trunk services run along the frontage and where the connection points are. The holder also needs to know whether any old line crosses the plot itself. Allotment drawings show the planned position of trunk lines, not always the built position, and the difference can be a few metres.

1. Frontage scan: water, sewer, power and telecom lines along the road edge, with depths at the planned entry gates.
2. Connection points: chambers, feeder pillars and valve pits confirmed on the ground.
3. Plot grid: a radar grid across the plot, aimed at older farm or village services.
4. Ground marking: lines painted and handed over to the building contractor before excavation.

Warehouses, logistics parks and factories all use the same check, with the plot scan growing to match the footprint.

How do we survey a corridor or a new industrial city?

Road by road and sector by sector, so each area can be handed over with a complete drawing while the next is scanned. The method follows the same principles as any careful excavation check: records first, then scanning, then confirmation with each owner before digging. The step-by-step guide sets out those principles for Indian sites in more detail.

• Developer and package drawings are combined into one base map on the project grid.
• Main roads and service corridors are scanned with radar along and across their width.
• Locators trace live cables and metal pipes, and chambers are opened where allowed to confirm the utility lines.
• Differences from the design drawings are listed for the developer and each package contractor.

Working alongside parallel construction packages

On a live new city, our crew often scans a road while two or three other contractors are still working on it. We agree the sequence with the developer's site team. Each stretch is scanned after its services are backfilled but before the road crust closes. Every line is then in its final place, and errors can still be fixed without breaking a finished pavement. Where a package is still open, the stretch is marked provisional and scanned again later.

The same record helps settle disputes. When a trench for one package damages another's pipe, the dated data collected shows what was in the ground and where. That saves weeks of argument between contractors.

Industrial corridor survey at a glance

What a typical corridor or new-city survey covers.

Where designers need a graded report, each line can be given a quality level under our SUE survey service.

How are corridor-scale surveys priced?

By scanned length, at ₹24 per metre for a standard GPR scan or ₹32 per metre with an L-section, plus GST. Large whole-order discounts make corridor-scale work cost-effective. The discount is 25% above 100 km, 40% above 500 km and 50% above 1,000 km. For example, 120 km of road scanning at the standard rate is ₹28,80,000 before discount and ₹21,60,000 after the 25% reduction, plus GST.

A single plot survey falls under the minimum order: ₹50,000 within Delhi NCR and ₹1,00,000 elsewhere, which includes Dholera and AURIC. The full card is on our GPR survey price list.

How does the data feed the city's GIS?

Every line we record carries attributes such as type, size, material, depth range, owner and confidence. It drops straight into the city's GIS instead of living in a PDF. New industrial cities are planned as digital, managed estates, and underground utility mapping that matches the ground is central to that. Formats and layer structure are explained on our page on CAD and GIS utility mapping. For a scope and price for your node, sector or plot, ask our engineers.

Frequently asked questions

Is a survey needed if the developer has given us drawings?

It is wise. Allotment and design drawings show where services were planned, and the built position can differ by a few metres. A frontage scan confirms them before you dig.

Can you survey before roads are built?

Yes. A pre-development scan of the land finds farm, village and pipeline services early, when trunk alignments can still be adjusted cheaply.

Do you survey warehouses and logistics parks in corridor nodes?

Yes. The plot check is the same as for a factory. It covers the frontage, the connection points and the building footprint before the construction project starts.

How do you handle cross-country pipelines?

We detect and map them with radar and locators and record the marker posts. The pipeline operator should be contacted before any work in its right of way.

Can the results go into the city's GIS?

Yes. We supply shapefiles or other GIS formats with attributes for each line, alongside DWG and PDF drawings.

What do you need for a quote?

The node or plot location, the road lengths or plot area to be scanned, and any developer drawings you hold.
