GPR Survey — Central Delhi
GPR Survey in Connaught Place, Central Delhi — Utility Detection
Ninety years of servicing threaded beneath a colonnade that cannot be disturbed, above two metro lines, in the most trading-sensitive ground in the country.
Twenty-two years, 1.5 lakh+ km surveyed, 100 km a day at full stretch and 700 KM in a single 30-day month, all delivered on owned fleet. No minimum order value applies here — this is inside NCR and our yard is in Faridabad. Elsewhere in India the figure is ₹1,00,000 per project.
Quick AnswerMezux Touch runs GPR survey across Connaught Place and the surrounding central business district — the inner, middle and outer circles, the radial roads, Janpath and the Barakhamba corridor. Heritage protection, metro interchange density and trading-hour constraints make this the most access-limited survey environment in Delhi.
Ninety years of accumulation
Connaught Place was serviced when it was built and has been reserviced continuously ever since — every era of power distribution, water, drainage and telecom laid into the same limited width, largely without a consolidated record surviving.
The colonnade and the heritage fabric mean the surface cannot simply be opened to find out. That makes this one of the clearest cases anywhere in the city for establishing the subsurface non-destructively before anything is planned.
Records here describe intentions from various decades rather than outcomes. Survey is discovery rather than reconciliation, and line spacing is planned on that basis.
Metro interchange beneath the circle
Two lines and a major interchange sit beneath the area, along with their structures, entrances, ventilation shafts and the diversions carried out when they were built.
Those diversions relocated services from their historical positions across much of the circle, and the diversion drawings are not always where a later contractor would think to look. Recent survey data is worth considerably more here than an older record, and we date every issue prominently.
Trading hours govern everything
The district trades from late morning to late night and pedestrian density through the day makes survey work impractical on most of the circle. Working windows are early morning, and they are short.
Productivity is therefore a fraction of open-corridor rates. We quote Connaught Place on its real conditions rather than blending it into a central Delhi average that would describe neither this nor anywhere else.
Enterprise density and diverse routing
The Barakhamba corridor and the surrounding office stock carry a concentration of enterprise connectivity, with multiple operators having laid duct along the same constrained approaches over many years.
Diverse-path verification is regular work — establishing whether two carrier routes genuinely remain physically separate, which in a corridor this congested is a question that occasionally produces an uncomfortable answer.
Approvals and deliverables
Work may involve the New Delhi council area authority, the PWD, the metro corporation, heritage authorities on the protected fabric, and the power and water utilities on their own assets.
Output is layered CAD with depth annotation, GIS files where kept, a PDF issue set and a report stating coverage and limitations by section, with metro-diverted stretches identified explicitly so nobody works from a superseded assumption.
Sectors that call us in here
Civic and heritage work leads — streetscape, drainage and conservation schemes where establishing the subsurface without opening it is a condition of proceeding.
Enterprise connectivity and building services work follows, with metro-adjacent contractor surveys making up the rest.

This area also generates RCC slab and wall scanning, post-tension cable detection and underground cable detection.
Frequently asked questions
Yes, in early-morning windows before trading begins. Pedestrian density makes daytime work impractical on most of the circle, so productivity is a fraction of open-corridor rates and quoted accordingly.
Not on their own. Ninety years of reservicing plus metro-related diversions mean records describe intentions from various decades rather than current outcomes. Survey here is discovery, not reconciliation.
Substantially. Construction relocated services across much of the circle, and diversion drawings are not always filed where a later contractor would look. We date every issue for that reason.
The survey is entirely surface-based and leaves nothing behind, which is precisely why it suits protected fabric. Any subsequent excavation is a separate and much harder permission question.
Yes, and it is regular work on the Barakhamba corridor. Multiple operators have laid duct along the same constrained approaches over many years.
None. Connaught Place is inside NCR, and given how short the working windows are here most jobs are small by necessity, so a minimum would make the work impossible. Beyond NCR the figure is Rs 1,00,000 per project.
On open ground with day and night shifts we have held up to 100 km a day using company-owned equipment. Across one 30-day period we have recorded 700 KM completed. Cumulative delivery has now passed 1.5 lakh km of GPR survey. The rate on your corridor will follow its congestion, the access you have and the confidence level you need.

Mezux Touch works Connaught Place under a constraint most corridors never impose: the survey has to finish before the district opens. Radar reaches roughly 1.5 to 2.5 metres here, but the binding limit is the pre-trading window rather than the alluvium. Ninety years of continuous reservicing sit beneath a colonnade that cannot be opened to check, and two metro lines have relocated services across much of the circle since. Records here describe intentions from various decades; the survey describes what is actually there.
How the survey is run here
How the grid is laid out in Connaught Place depends entirely on what the ground returns. Cross-lines are tightened wherever the material could imitate a service on a single pass. Rather than one calibration per job, we take one per ground condition encountered. The work is done by directly employed crews on company-owned systems, with no critical activity sub-let.
What you receive
Layered DWG in your convention, each line attributed by depth, detection method and confidence. SHP or KML for a maintained GIS, plus a PDF issue set. A signed report covering extent, per-section depth, no-access ground and every limitation. Connaught Place packs identify metro-diverted stretches explicitly, because a drawing that predates those works is worse than no drawing at all. Approvals may involve the New Delhi council area authority, PWD, DMRC, heritage bodies on the protected fabric and the power and water utilities. Original records are retained and reissuable.
Beyond the basics
Are old drawings reliable here? Not on their own. Ninety years of reservicing plus metro diversions mean records describe intentions from various decades rather than outcomes.
How much can you cover in a shift? A fraction of an open corridor. The pre-trading window is short and pedestrian density closes the day quickly.
Can you work around the colonnade? The survey is entirely surface-based and leaves nothing behind, which is precisely why it suits protected fabric.
Is diverse routing verifiable on Barakhamba? Yes, and it is regular work. Several operators used the same constrained approaches over many years.
Do you mark findings on site as well as on the drawing? Where the client asks for it, yes, in temporary paint or pegs agreed beforehand. Marks are for the immediate works and are not a permanent record.
Terms used on this page
Diversion drawing — a record of services relocated during construction, often filed apart from the main utility record. Trading window — the short period before shops open during which survey work is practical. Protected fabric — built heritage that cannot be disturbed, which makes non-destructive investigation the only first option. Superseded record — a drawing overtaken by later diversions, still in circulation and still being worked from. Unattributed find — a detected service that no asset owner claims, reported as such rather than assigned on plausibility. Quality level — a SUE grading describing how utility information was obtained, from records only through to physical verification.
