OFC & Telecom Route GPR Survey in Delhi

Rates and page checked: 23 October 2026

What does a telecom cable route survey in Delhi involve?

Fibre in Delhi rarely gets a road to itself. A new duct usually has to fit into a footpath or verge that already carries other operators' ducts, power cables of the local distribution network, water lines and house connections. A telecom cable route survey in Delhi tells the route designer what is already in that band and where a clear path remains.

The crew works along the proposed alignment and records:

• existing OFC ducts and copper telecom cables, including empty HDPE ducts;
• HT and LT power cables and street-light feeds;
• water mains, sewers and drain crossings;
• chambers, handholes and manholes visible at the surface;
• obstructions such as old foundations or buried slabs.

Findings are marked on the ground and listed in a signed report. The general service is described on our OFC route GPR survey page; for other kinds of work across the capital, see the Delhi GPR survey page.

Why is there so little room for new fibre under Delhi roads?

Several layers of telecom history sit in the same narrow strips. Copper networks came first, then successive rounds of fibre by different operators, each placed where it was easiest at the time. Power cables from BSES Rajdhani, BSES Yamuna, Tata Power-DDL or NDMC, depending on the area, often run in the same verge. Footpath rebuilding, metro works along DMRC corridors and drain upgrades have moved some services and left others where they were.

The practical result is that drawings rarely match the ground. A route designed from records alone can run straight into a duct bank that was never mapped. Scanning first shows where the band is full, where it is shared and where a new duct can go. Mezux Touch is not affiliated with any telecom operator, DISCOM, municipal body or development authority; we survey for whichever contractor or operator places the order. Route planning for operators across the region is discussed in our guide for Delhi NCR fibre operators.

How is duct feasibility checked along a Delhi road?

Feasibility is a simple question with a detailed answer: can the duct go where the design puts it? We answer it in three passes.

1. The design band. Radar lines run along the proposed position for the full length, with cross-lines at regular gaps and at every chamber or junction.
2. The alternatives. Where the design band is crowded, the opposite verge, the footpath back edge or the median is scanned so the designer has a fallback.
3. Pit and chamber positions. Proposed manhole and handhole locations get a closer grid, because each one is a small excavation in its own right.

The report then shows which stretches are clear, which are tight and which need re-routing. An optical fiber route survey in Delhi is most useful at this planning stage, before permissions are filed against a fixed alignment.

Trenchless utility survey in Delhi: how are HDD crossings checked?

Most fibre routes cross arterial roads, drains and sometimes railway lines by HDD. A trenchless utility survey in Delhi scans the full bore path between entry and exit, plus the two pit areas, for services at every level the bore could reach. Junctions get the tightest grid, since water, sewer and power lines tend to meet there.

Points that usually need extra attention:

• crossings beside metro piers or near underground station boxes, where permission from DMRC is the project owner's responsibility;
• drain and nala crossings, where the bore must clear the structure;
• approaches to Yamuna bridges, where wet floodplain ground limits how deep radar can see.

Our HDD route survey services in Delhi feed directly into bore design. Mezux Touch also owns 18 HDD rigs; drilling is a separate service, described on our HDD page and quoted on its own.

Does Delhi's ground change what radar can see on a fibre route?

It does, and a long route can pass through several kinds of ground. Made-up fill under older roads, alluvium in much of the city, quartzite near the ridge and soft, wet floodplain in the east each behave differently. Fibre ducts are often shallow, which helps, but deeper crossings are where reach matters. The report states the depth reached on each section rather than one figure for the route.

What does a telecom infrastructure survey in Delhi cost?

Pricing is per metre of alignment: ₹24 for a standard route survey and ₹32 when a depth profile (L-section) is wanted. Inside Delhi NCR the only floor is a 4 km minimum length, so no per-project minimum is added. GST is extra.

Discounts are applied to the entire order once it crosses a slab – 25% above 100 km, 40% above 500 km, 50% above 1,000 km. Mobilisation, night shifts, traffic arrangements or permissions, and CAD/GIS drawing sets are separate lines. See the GPR survey price list for all slabs.
