FMDA GPR Survey for Faridabad Master Roads and Trunk Mains

What does an FMDA utility survey cover?

An FMDA utility survey maps trunk services along Faridabad's master corridors before new mains, widening or crossings. It covers Ranney well mains, master sewers, storm drains, and the power and fibre lines on master sector roads.

The Faridabad Metropolitan Development Authority was created by the FMDA Act, 2018, and is chaired by the Chief Minister of Haryana. The municipal corporation runs local streets; FMDA builds the backbone of bulk water, trunk sewerage, master roads, drainage and mobility. Its construction projects are long and linear, and almost each one crosses underground utilities owned by others.

Which survey type fits which FMDA work?

Corridor mapping for long master roads and pipelines, crossing surveys with L-sections for bores, and pre-excavation checks right before digging.

Sectors that remain with the state development agency are handled with that agency's records; see when you need an HSVP utility survey.

How do you map the Ranney well water mains?

These mains are long, large and laid in phases with different materials. We trace the metal sections, scan the rest with GPR and fix the line at every valve and chamber.

Much of Faridabad's drinking water comes from Ranney wells along the Yamuna and reaches the city through trunk mains past farmland, railway lines and busy roads. The geophysical idea behind ground penetrating radar is timing: it measures how radar waves return from buried objects. On the wet eastern alluvium those reflected signals fade early, so the locator and chamber positions carry more weight. Every sheet carries a usable-depth note, telling the designer where a trial pit is worth digging. Soil conditions elsewhere in the city are covered if you read about GPR survey in Faridabad.

Why use corridor mapping on master sector roads?

A master sector road is a shared strip where supply mains, sewers, power, fibre and drainage run side by side. A corridor record shows all utility lines against fixed offsets, not only the one you are working on.

We divide the road into chainage strips, scan each from kerb to kerb with crossing passes, and draw every line with its offset from the kerb or centre line. A widening design can then shift the carriageway and see which services fall under it. Strip conventions and offsets are explained in our page on utility corridor mapping.

FMDA recharge and storm-water projects need the same care, as recharge pits, outfalls and culverts often land where several services meet at a low point. A corridor survey of that stretch before design avoids moving a pit after it is dug.

The same strips turn the data collected into GIS utility mapping. FMDA projects touch many agencies, and a single layered record of a corridor saves each of them from scanning the same metres again.

When does an HDD crossing need checking first?

Before every bore. Under master roads, storm drains and the Delhi–Mumbai Expressway link, the drill path and both launch and receiving pits must be cleared of existing services.

Radar covers the bore line and a band on each side, services are painted at the surface, and the drillers receive an L-section to set their depth. Our own company runs HDD rigs, so the survey is drawn the way a drilling crew reads it. Pit positions matter as much as the bore, since a launch pit over a fibre duct bank cuts service like a drill strike. Each pit outline is painted before the rig arrives, with nearby services recorded. For the scope of a bore-path check, see HDD route survey at a glance.

How do road cutting permission and tenders fit in?

The survey drawing supports both. It shows the road owner what you will cross and shows a bidder what the package contains.

Master roads may sit with FMDA while the side roads they meet are with the corporation, so one pipeline can need permission from two bodies. Local streets are covered on MCF utility survey for Faridabad sites, and the application steps are in our road cutting permission Faridabad guide. A tender survey targets junctions, drain crossings and market frontages, so bidders price utility shifting from evidence.

Valve chambers that mark a trunk main

The Ranney well mains that carry Yamuna water across Faridabad are large, deep and costly to damage, so a rough route line is not enough. On FMDA work we tie the corridor to DGPS control and fix every valve chamber, scour and air valve along the main with a total station. Between those points, radar and a locator follow the pipe, and both records are drawn together with levels. Years later a widening contractor can start from real positions instead of a tender sketch. Learn more about DGPS for long corridors and fixing valve chambers by total station.

What does an FMDA utility survey cost?

As a Delhi NCR city, Faridabad is billed at ₹24 a metre for a standard GPR survey and ₹32 a metre with an L-section, against a ₹50,000 minimum order. GST is charged on top.

• A 7.5 km trunk sewer alignment with an L-section: 7,500 × ₹32 = ₹2,40,000 plus GST.
• A 120 km water main corridor at the standard rate: ₹28,80,000 at list rate, less 25% for an order above 100 km, giving ₹21,60,000 plus GST.
• Whole-order discounts climb to 40% once a programme passes 500 km and to 50% past 1,000 km.

There is no minimum length. FMDA corridor surveys reach us as orders from the authority itself and from the pipe-laying firms, design consultants and power utilities building its mains and roads. Either way, an in-house Mezux crew runs each ground penetrating radar survey from the Sector 41 office with radars we own. The field work is not outsourced.

Frequently asked questions

Will radar pick up a trunk main from the Ranney wells?

In most cases, at normal depth. On the wet eastern side, metallic pipes are traced and the line is fixed at valves.

Do you survey crossings of the expressway link?

Yes. Both pits and the bore line between them are scanned, and the drillers get an L-section.

Can you map a master sector road in Greater Faridabad?

Yes, as chainage strips from kerb to kerb, with offsets and depths for all buried utilities.

Do you cover all of Faridabad district?

Yes, from Ballabgarh to the Delhi border; see utility line survey in Faridabad.

Can you support an FMDA tender bid?

Yes, with a short tender survey whose GPR data covers the most congested points in the package.

How far is your crew from FMDA sites?

We are based in Sector 41, a short drive from most Faridabad sites.
