HT/LT Cable Route GPR Survey in Noida

Rates and page checked: 23 October 2026

What should an electric cable route GPR survey in Noida settle before trenching?

A new HT feeder or LT distribution cable in Noida seldom gets a clear strip of ground. Sector roads already carry water mains, sewers, storm drains, telecom ducts and older power cables, and the safe line for the new cable is whatever space remains between them. An electric cable route GPR survey in Noida answers three practical questions before a trench is opened or a bore is set out:

• Which existing services run along the proposed alignment, and how far from it do they lie?
• Where must the new cable cross another service, and at roughly what depth?
• Which stretches are so crowded that the alignment ought to shift to the other side of the road?

We answer them with radar and EM locating on the actual ground, paint or peg each find, and hand over a signed report. Our HT/LT cable route GPR survey service page sets out the method for any city; what follows is how it works on Noida ground.

Where do Noida cable alignments run into the most buried services?

The Noida Authority planned the city as numbered sectors, and that layout produces a few predictable pressure points for anyone routing power cable:

• Sector dividing roads. The wide roads between sectors carry trunk services for both sides, so a feeder along them shares the verge with mains and ducts of several owners.
• Plot frontages inside sectors. Each building's water, sewer and power connection crosses the frontage strip, leaving a dense run of short, shallow service crossings.
• Around substations and ring main units. Cables bunch together where they leave a substation, so a new circuit has to find room among the existing ones.
• Along the Noida–Greater Noida Expressway. Its service roads and verges form long, busy corridors where fibre for IT campuses and data centres often runs beside power cable.
• Near the Blue Line and Aqua Line. Metro construction usually involves shifting services, so older drawings close to these alignments deserve extra caution.

Our GPR survey page for Noida covers the city's ground and authorities in general; the points above are the ones that weigh most on cable work.

How is underground electrical line tracing in Noida carried out on site?

1. Route walk with the drawing. The crew compares the proposed alignment with the ground, noting chambers, feeder pillars, poles, RMUs and any visible cable markers.
2. EM sweep. A locator picks up live cables and other conductive lines from the current they carry, or from a signal applied where a line can be connected safely.
3. Radar lines. GPR runs along the route and across it, with extra lines at junctions, frontages and planned crossings. Radar sees plastic pipes, empty ducts and cables that give EM nothing to follow.
4. Marking. Paint or pegs in the right utility colour go down over each service, with its estimated depth noted alongside.
5. Report. Findings, the depth radar reached on each section and any no-access stretches go into a signed report.

Live HT cables are located without contact; our crews never open joints or cut into a cable. For a closer look at how the two methods divide the work, read how GPR traces HT and LT cables.

HT cable route mapping in Noida: how are Expressway, metro and drain crossings handled?

Crossings are where a cable route most often goes wrong. On a long Noida feeder they typically include sector roads, the Expressway or its slip roads, metro corridors and the larger storm drains. Each gets its own treatment:

• HDD crossings. When a crossing will be bored, we scan the bore line and the pit areas at both ends, as far as access permits, so the drilling team can plan a profile that clears what is there. See our HDD route survey page.
• Open-cut road crossings. A closer grid of radar lines covers the whole crossing width, because services from both sides of the road converge there.
• Drains and nalas. Culvert positions are recorded so the designer can decide whether the cable goes under or over.

Main carriageways may only be free in night windows. Permission to work there, or close to a metro corridor, is for the project owner to obtain; night-shift working and traffic arrangements are charged separately from the survey rate.

Who hires a power cable mapping company in Noida?

Cable surveys here are mostly ordered by the people who must lay or protect a cable, not by the network owner. Typical clients are:

• EPC and electrical contractors laying 11 kV or LT cable under distribution works;
• developers bringing feeders into group housing, commercial towers or industrial plots;
• IT campuses and data-centre builders planning dedicated or second supply routes;
• consultants preparing an electric grid underground survey in Noida for a design or a tender.

PVVNL supplies electricity in Noida, so much of the existing cable along a city route will belong to its network. We have no affiliation with PVVNL, with the Noida Authority, or with any DISCOM, civic body or development authority; the client who needs the ground checked engages us and receives the report. A wider view of distribution cabling in the region is given in HT/LT cable mapping for Delhi NCR DISCOMs.

What does a Noida cable route survey cost?

Charges run per metre of route: ₹24 for the standard scan and ₹32 once an L-section depth profile is added. Inside Delhi NCR the single floor is a 4 km minimum length, so no ₹1,00,000 project minimum applies to Noida work. GST is added to the invoice.

For big distribution packages the slab is applied to the entire length – a quarter less above 100 km, 40% less above 500 km, half above 1,000 km. Crew mobilisation, after-hours shifts, traffic management or permits, and CAD/GIS drawings never sit inside these numbers; they are priced item by item. The slab table sits on our price list.

Does your Noida work order need a standard survey or an L-section?

The standard option pins down where each service lies and estimates its depth where it was measured, which suits most LT work and short HT links. Plenty of 11 kV work orders go further and want the depth of existing services profiled end to end, so the designer can fix cable depth and crossing levels. That profile is what the L-section adds, at ₹32 a metre. If the survey clause in your tender reads ambiguously, send it with the route and we will say which option it calls for. More detail is on our L-section GPR survey page.
