OFC & Telecom Route GPR Survey in Mumbai

Rates and page checked: 23 October 2026

What does a telecom cable route survey in Mumbai settle before the duct goes in?

The aim is simple: find a strip of ground along the planned alignment where a duct can be laid at the required depth without hitting anything. A telecom cable route survey in Mumbai checks the full length of that alignment and answers four practical questions:

• Is the proposed side of the road usable, or is it already full of ducts and cables?
• Where are the services that a trench or micro-trench would cut through?
• Which crossings are better bored than trenched, and what does each bore need to avoid?
• Where should manholes or handholes go so they do not land on top of an existing service?

Our general approach for fibre routes is described on the OFC route GPR survey service page, and the practical side of routing is covered in our guide to GPR scanning for OFC routing.

Why is kerbside space so tight for fibre in Mumbai?

Several operators have laid fibre along the same Mumbai roads, and each new duct tends to go where the last one went – along the footpath edge or the carriageway shoulder. That strip also carries:

1. BMC water lines, sewers and storm drains, some of them very old;
2. power cables belonging to BEST in the island city, or to Adani Electricity, Tata Power or MSEDCL elsewhere;
3. services diverted along Mumbai Metro lines, which may not match older records;
4. house and building connections crossing from the main line to each property.

Reclaimed coastal land adds a further problem. Fill with rubble and debris returns scattered reflections, and saline groundwater absorbs the radar signal, so depth reach varies from one stretch to the next. The report records what depth was actually reached on each section of the fibre route.

Trench or HDD – how does the scan steer the method?

Open trenching on a busy Mumbai road is slow to permit and disruptive to traffic, so many fibre routes use horizontal directional drilling at junctions, nalas and arterial crossings. A bore that hits an unseen pipe, though, does more damage than a trench, because nobody sees it happen. That is why a trenchless utility survey in Mumbai checks each bore separately:

• the entry and exit pit areas, scanned on a grid;
• the bore path between them, with lines across and along it;
• services lying near the planned bore depth, flagged for the drilling team;
• points where radar could not resolve depth, with a recommendation for a trial pit.

Mezux operates 18 HDD rigs of its own, and our HDD route survey services in Mumbai follow the method on the HDD route survey page. The bore design and drilling remain the contractor's responsibility unless we are engaged for them too.

Can radar find another operator's HDPE duct?

Often, yes. An EM locator cannot follow a plastic duct unless it carries a metal tracer wire or a metal-sheathed cable, but radar responds to the contrast between the duct and the soil around it. Ducts holding cables usually show more clearly than empty ones. Very small ducts, ducts deep in wet ground and ducts bundled tightly together are harder to separate, and the report says where detection confidence is low.

Where a duct shows in a chamber or handhole, we use that point to identify the run and follow it along the route. Ownership is only recorded when markings or records support it; otherwise the duct is listed as an unidentified telecom service.

What does an optical fiber route survey in Mumbai cost?

Pricing follows the metre rate on our rate card – ₹24 for each metre of standard survey, or ₹32 per metre when an L-section depth profile is wanted along the route. Orders shorter than 4 km are billed as 4 km, and since Mumbai is outside Delhi NCR, no project is billed below ₹1,00,000. GST is charged on top.

Once the order passes 100 km, 500 km or 1,000 km, the 25%, 40% or 50% discount covers every metre in it. Mobilisation from Faridabad, night working, traffic arrangements and permissions, and CAD/GIS drawing sets are always quoted separately. The complete slab table sits on the GPR survey price list.

Which telecom infrastructure survey items can be added?

Beyond the duct line itself, a telecom infrastructure survey in Mumbai can include scans at proposed manhole and handhole positions, building entry points, tower or node sites, and crossing points under railway or metro land where access is arranged by the owner. An L-section can be added on chosen stretches. Fault locating on an existing cable is a separate service, quoted on its own.

For operators planning long-haul links into the city, our telecom EPC work in Mumbai page covers duct and fibre laying. Crews and systems mobilise from Faridabad, and dates are agreed with you once permissions are clear.
