HDD Route GPR Survey in Vadodara

Rates and page checked: 23 October 2026

What do HDD route survey services in Vadodara cover?

HDD route survey services in Vadodara prepare the ground for a directional bore before the rig arrives. A bore is blind in a way a trench is not: the driller steers the head from the surface and never sees what it passes. The survey therefore has to tell the bore designer what lies in the way and how much room there is around it.

For each crossing or bore section the survey normally covers:

• the entry pit and rig set-up area, where the drill string starts at a shallow angle;
• the bore path itself, with a corridor wide enough to allow for steering drift;
• the exit pit and the strip where the pipe or duct string is laid out before pullback;
• every service crossed – power cables, water and sewer mains, gas pipes, telecom ducts – recorded with position and approximate depth.

Fibre projects with many short bores are covered from the planning side on our OFC route survey in Vadodara page.

Which Vadodara crossings usually need a bore?

Open cutting is often refused, or simply impractical, at these places around the city:

• NH-48 and the Ahmedabad–Vadodara Expressway – national highway land where cutting across the carriageway is seldom permitted.
• Western Railway tracks at and around Vadodara Junction and the lines branching from it, where railway consent decides how the crossing is made.
• The Vishwamitri river and its nalas, which cut across many city routes, and the canal branches on the urban fringe.
• Busy arterial roads and circles inside the corporation area, where traffic and fresh surfacing make open trenches unwelcome.
• GIDC estate roads at Makarpura, Nandesari, Por and elsewhere, where plant gates and pipe racks leave little room to dig.

Approvals at these crossings are discussed in our article on HDD crossings of Gujarat roads and canals.

How deep can a utility survey before horizontal directional drilling see?

Depth is the main limit on any utility survey before horizontal directional drilling in Vadodara. On the city's alluvium with moderate clay, our field notes put radar reach at something like 2.5 to 3.5 metres where the ground is open. Bores under tracks, highways and canals are often planned deeper than that, and damp ground near the river shortens the reach further.

The survey report therefore keeps two things apart: the services we detected with their depths, and the depth band below which radar could not confirm anything. If the bore profile drops into that unconfirmed band, the report says so in plain words. The drilling team can then use owner records, trial pits at the entry and exit points, or a borehole on request to check the deeper zone before committing the rig.

Why scan the entry and exit pits so closely?

A large share of bore strikes happen near the two ends rather than in the middle. At entry and exit the drill string is shallow and climbing or diving steeply, so it passes through the same depth band as house connections, cable joints and shallow ducts. Pits are also opened by excavator, frequently in a hurry.

We grid the pit areas more densely than the bore path and mark them on the ground, so the pit crew knows where to dig by hand. Where a chosen pit spot is congested, the report suggests shifting it a few metres to clearer ground, which usually costs far less than protecting or diverting an existing line.

How does the survey feed the bore profile?

A bore designer needs a clearance figure from each service the bore passes. The standard ₹24-a-metre survey places the detected services in plan and notes their depth where measured. Choosing the ₹32-a-metre L-section instead gives a running depth profile of the same services along the bore, so the designer can draw the bore curve against them in one view. More detail is on our L-section GPR survey page.

If the contract asks for that profile, order it at the outset; it costs less than sending a crew back. When the choice between boring and trenching is still open, our comparison of trenchless and open-trench methods may help.

Why do crossings in central Gujarat need more care now?

Central Gujarat has long depended on overhead power lines. Power Line reported in August 2021 that MGVCL's underground line length in March 2020 was only 0.114 times its overhead length. The balance is now moving. In August 2026 a listed contractor reported emerging L1 on MGVCL work worth ₹275.05 crore (Kalkine), and in October 2026 an order of ₹471.92 crore was reported (Whalesbook), both for underground networks and covered-conductor conversion, with Borsad, Nadiad City and Baroda among the areas named.

Underground cabling on that scale means a great many road and drain crossings by HDD, often in streets where water, gas and telecom lines already compete for space. Contractors on such work need crossing surveys they can hand straight to their drilling teams. To be clear, Mezux Touch has no link with MGVCL or any other DISCOM – no order, no empanelment, no approval – and takes instructions only from the contractors and owners who hire it.

What does an HDD route survey cost in Vadodara?

Bore paths are billed by the metre of route scanned – ₹24 for the standard survey, ₹32 with the L-section. The 4 km order minimum applies, and so does the ₹1,00,000 project minimum that covers every site outside Delhi NCR; so a handful of short crossings is cheaper when ordered together with the rest of the route. GST is extra.

• Five road and nala crossings totalling 1.2 km: billed as 4 km, or ₹96,000, then raised to the ₹1,00,000 project minimum.
• A 40 km cable route with bores at each crossing, surveyed with an L-section: 40,000 × ₹32 = ₹12,80,000 before GST.
• The same route as a standard survey: 40,000 × ₹24 = ₹9,60,000 before GST.

Mobilisation, night working, traffic management and permissions, and CAD/GIS drawings are separate items. The GPR survey cost guide explains how slabs apply to larger orders. Mezux Touch also drills with 18 HDD rigs of its own – see HDD services – while ground, approvals and localities for the whole city are summarised on the main Vadodara GPR survey page.
