GPR Survey in Narela, North West Delhi — Industrial Utility Detection

Mezux Touch surveys Narela through sandy low-clay ground at Delhi's northern edge, favourable for radar, where achievable investigation depth is typically 3 to 4 metres, among the best conditions in the capital. The depth ceiling is the honest constraint here; coverage rate is a secondary concern. Where your works go deeper than the ground allows, we say so at scoping and recommend electromagnetic locating or physical verification rather than issuing a report that cannot support the decision.

How the survey is run here

The survey pattern for Narela is decided after the ground is assessed, not before. Where the ground itself reflects, we add perpendicular passes to separate the material from real utilities. Rather than one calibration per job, we take one per ground condition encountered. Everything is delivered by our own crews on our own equipment, so a start date is a commitment rather than a forecast.

What you receive

A layered CAD issue in DWG matching your standard, where each detected line carries its depth, how it was detected and how far it can be relied on. Where a GIS exists we deliver into it as SHP or KML, and a PDF issue accompanies every package. A signed report giving coverage, per-section depth, inaccessible areas and an explicit statement of what the survey could not establish. On Narela work the report also records the authorities involved — the north corporation zone, DSIIDC on estate land, DDA on planned pockets, PWD, the railways at crossings — because the deliverable has to satisfy whichever of them receives it. We archive the underlying radar records, which matters when a drawing is challenged during a dispute rather than during construction.

Beyond the basics

Why is the ground better here? Sandy, low-clay material lets the signal travel further, so plot surveys generally resolve in a single visit rather than ending inconclusive.

How are HT routes handled? Reported separately with their own confidence statement, and critical crossings nominated for physical verification rather than cleared on detection alone.

Do you work inside operating plants? Yes, to the plant's permit and escort system, with internal records held by the operator rather than the corporation.

How do rail crossings work? Cover is specified by the railway and approval runs on possession-driven timelines, so those are identified at scoping.

Is the survey affected by traffic or vibration? Not materially. Radar is not a seismic method, so passing traffic does not corrupt the record, though it does constrain where and when a crew can stand.

Terms used on this page

Process and effluent route — industrial pipework flagged separately because breaching it is a regulatory matter. Depth confidence — the reliability that can be placed on a stated depth, higher in low-clay ground. Compressed air line — undocumented industrial pipework whose loss stops a production line as effectively as a power cut. Electromagnetic locating — a complementary method that traces conductive services by their signal, used where radar alone cannot resolve them. Duct bank — several ducts encased together in concrete, which reads as one structure rather than as separate lines.
