CIDCO GPR Survey and Utility Mapping for Navi Mumbai Nodes
Radar scans, corridor maps and crossing checks for CIDCO nodes, new-town roads and service lines across Navi Mumbai and beyond.
Quick AnswerA CIDCO GPR survey settles, node by node, the paths of underground utilities ahead of any trench, bore or widening. The same method serves Vashi, Kharghar and NAINA lanes. Ground penetrating radar (GPR) passes, a cable locator and opened chambers together produce the CAD and GIS set we deliver. Many CIDCO jobs involve crossings under creeks, nalas or busy roads; for those, see HDD route survey.
How is CIDCO different from a city corporation?
CIDCO is a state-owned new-town developer and planning authority, so a CIDCO utility survey often covers land where services are still being laid. The City and Industrial Development Corporation of Maharashtra was incorporated on 17 March 1970 under the Companies Act, 1956, to build Navi Mumbai across the harbour from the old city.
It planned the city as a string of nodes. Each mature node passed to a local body for civic upkeep. The Navi Mumbai Municipal Corporation took the north and, from 2016, the Panvel Municipal Corporation took parts of the south. CIDCO still develops the airport influence area, NAINA, where town-planning packages worth about ₹7,924 crore were awarded in September 2025.
Which CIDCO projects need buried services mapped?
Anything that cuts into a road, a plot frontage or an open strip where earlier contractors have laid lines. The new Navi Mumbai airport opened on 8 October 2025, with first commercial flights on 25 December 2025. Metro Line 1 passed one crore cumulative riders in September 2025, and reports for further lines have gone to the state.
- Trunk water and sewer extensions into newer nodes
- Road widening and junction work near the airport
- Power and OFC corridors along sector roads, and NAINA roads crossing village lanes
- Utility shifting for metro and elevated road corridors
What changes between a mature node and a new one?
Mature nodes are crowded and poorly recorded; new ones are sparse but change every month. Vashi and Ulwe are therefore never scanned to one recipe.
| Node type | Typical finds below ground | Scan approach |
|---|---|---|
| Older nodes (Vashi, Nerul, Belapur) | Decades of mains, cables and ducts laid over one another | Close-spaced cross-lines; each metal service traced |
| Growing nodes (Kharghar, Ulwe, Dronagiri) | New trunk services plus temporary contractor lines | Full-corridor pass, rescanned while building continues |
| NAINA and village edges | Thin records, informally laid pipes and cables | Broader strip, extra points flagged for trial pits |
| Creek and nala crossings | Outfalls, deep mains, soft ground | Both pit zones gridded, profile drawn across |
Table note: for the output formats behind each row, see what we do: utility mapping.
How does Navi Mumbai's ground affect the scan?
It ranges from basalt hills to soft, wet creek-side land within a few kilometres, and radar depth falls sharply towards the creek. Radio waves leave the antenna in short bursts. This geophysical method listens for reflected signals off ducts, pipes and strata, so its range rests on the electromagnetic properties of Navi Mumbai soil. The city sits between the Parsik hills and Thane Creek, and many southern nodes, the airport site among them, stand on cut or filled land. Near the water the saline ground has high electrical conductivity and soaks up the signal.
On one route the crew may change antenna twice, from hill rock to creek fill. Metallic pipes and cables get walked with the locator, while lifted chamber lids supply taped depths. Creek-side access and ground behaviour are logged at GPR survey in Navi Mumbai details.
How do long CIDCO corridors get mapped?
Package by package, then joined into one layer, so a design team sees a node-to-node trunk main end to end. Trunk lines, metro alignments and new sector roads are scanned in packages and stitched on a single coordinate base, as explained on see utility corridor mapping.
Under a nala or creek road, we grid the launch and receiving pits and the strip joining them. The bore profile is then drawn to steer around what we found. Having 18 HDD rigs in the group, we lay the sheet out exactly as an operator at the drill console reads it.
What goes wrong when a node road is opened without one?
A burst main, a severed cable or a bore abandoned mid-way, any one of which dwarfs the survey bill. Kharghar, Ulwe and Dronagiri hide more risk than their neat layouts suggest. One contractor may lay a duct in a month and another may trench beside it the next, each working from a drawing that shows neither line.
No survey removes every risk, and we state plainly where the radar could not confirm a line. Buried utilities are identified and mapped as painted, measured lines on the construction site. The few uncertain points are named on the sheet for hand digging or a trial pit.
What does a CIDCO utility survey cost?
CIDCO packages are charged by the metre, subject to a minimum order of ₹1,00,000 per project.
- Radar scan in plan: ₹24 per metre
- Scan plus L-section depth profile: ₹32 per metre
- Project minimum: ₹1,00,000
- Discounts on the whole order: 25% over 100 km, 40% over 500 km, 50% over 1,000 km
- All rates exclude GST
A 5 km standard scan along a node road is ₹1,20,000. For 250 km of NAINA roads with L-sections, the full-rate figure of ₹80,00,000 falls to ₹60,00,000 after the 25% discount. CIDCO nodes fall to a Navi Mumbai colleague working from home; the opening pass lands on the day you confirm, or the working day after that. Any applicable travel or mobilisation figure sits on the quotation for you to see.
Can plot corners and services be fixed in one visit?
Yes, and on CIDCO land that saves a second mobilisation. Node layouts and NAINA schemes are drawn on plot numbers and sector grids, yet many lines predate the plot pegs. Our surveyors locate the scheme's reference pillars, peg the plot corners you name and plot each detected cable or pipe against them. Satellite fixes come from a DGPS survey for Navi Mumbai sites. Between compound walls in built-up sectors, a total station plot survey does the detailed pick-up.
Who scans CIDCO nodes, and on whose order?
Engineers on the Mezux Touch payroll, operating radars the company owns. Each CIDCO package draws on GPR surveys running back to 2003, a 58-system radar pool held in-house and audited ISO 9001, 14001 and 45001 systems. None of the work is sub-let. Some Navi Mumbai jobs arrive as a CIDCO work order in its own name. Others come from the civil contractor, design consultant or utility that holds a node or NAINA package.
For CIDCO utility mapping on a node, name it, sketch the route, give the start date and ask for a rate for Navi Mumbai in writing.
Frequently asked questions
Is a CIDCO road the same as an NMMC road?
Not always. Many mature node roads now sit with the municipal corporation. The page how our NMMC Navi Mumbai utility survey works covers those.
Can you work near the airport?
Yes, outside restricted zones and with the access permits the site requires. We plan scan times with the client's safety team.
Do you survey NAINA village lanes?
Yes. Records are thin there, so we widen the scan strip, rely more on utility detection in the field and mark extra points for trial pits.
Can radar map a pipe under a creek crossing?
Over water, no. A ground penetrating radar survey covers the banks and pit areas, and records and locator readings cover the crossing itself.
Do you need CIDCO's own drawings?
They help us decide where to scan harder, but they are never trusted on their own. Each line on our utility maps is verified during data collection on site.
