Bengaluru Central City Corporation GPR Survey for the CBD
Chickpet lanes, Cantonment brick drains and TenderSURE ducts: radar mapping for the densest streets of Bengaluru Central City Corporation.
Quick AnswerA Bengaluru Central City Corporation GPR survey untangles the BWSSB mains and sewers, BESCOM cables and fibre packed under the core before a footpath is lifted or a junction redrawn. It covers streets from Chickpet to Indiranagar. Generations of pipes share little room here, so ground penetrating radar (GPR) is backed by locator tracing and opened chambers. Old cast-iron and masonry lines get their own treatment in our page on underground pipeline detection.
Which services does a Bengaluru Central City Corporation utility survey pick up?
Whatever lies along your line through the core: BWSSB mains and sewers, storm drains, BESCOM cables, GAIL Gas pipes and operator ducts. Each gets a plotted route, a depth estimate and a likely owner. The street is painted to match, and the sheet suits the design, tender or permission file.
Of the five bodies created by the Greater Bengaluru Governance Act, 2024, Central covers the least ground, about 78 square kilometres, yet its subsoil is the most congested. It was notified on 2 September 2025, with 63 wards in the CV Raman Nagar and Gandhinagar zones. Its first council elections were still awaited in November 2026. (Sources: The Week, 2 September 2025; Deccan Herald, 13 September 2025; The South First, 20 November 2025; Telangana Today, 17 July 2026.)
Where do the Central corporation's limits run?
Broadly, the old commercial heart, the business district and the eastern neighbourhoods out to CV Raman Nagar. The 2025 notification built it from the Shivajinagar, Shanthinagar, Chickpet, Chamarajpet, Gandhinagar and CV Raman Nagar assembly areas. Ward names such as Vasanth Nagar, Sampangirama Nagar, Halasuru, Cox Town, Indiranagar and Jeevan Bhimanagar give a sense of its spread. (Source: Deccan Herald, 2 October 2025.)
Three kinds of street sit inside those limits. The old Pete around Chickpet has tight lanes and layered pipes, and the former Cantonment around Shivajinagar, Halasuru and Cox Town has mature trees and long-buried brick drains. The business district and Indiranagar carry busy arterials, duct banks and dense fibre.
Why are the core's services so hard to read?
Bengaluru's piped networks began here, so lines of every age lie stacked in one narrow strip. Cast-iron mains, masonry sewers, plastic pipes and fibre bundles may share one footpath, and these buried utilities seldom match the records. Patch repairs never reached the record sheets, and disused pipes were mostly left buried.
Ground penetrating radar is a geophysical method that images the subsurface with pulses of radio waves, and it picks up most of these lines. Busy targets overlap, though, and brick-and-stone fill scatters the reflected signals. Scans therefore run in two directions, the locator traces metallic pipes, chamber covers come up for depths and trial pits settle key crossings.
Time on the street is the other limit. Shop fronts, parked two-wheelers, hawkers and traffic leave short windows for scanning. We walk the route first and agree slots with you and the traffic police. Long streets are broken into stretches that one shift can finish.
Most central enquiries involve water and sewer replacement, storm-drain repair, junction redesign, fibre routes and building connections. The comparison of detection methods is worth reading first.
What sits under the redesigned business-district roads?
Many central roads were rebuilt to the TenderSURE design, which moved services into ducts and chambers under widened footpaths. The utility lines are more orderly as a result. The widened footpath now carries most of the risk, and a new line must squeeze into ducts and chambers that are already busy.
A redesigned road still has utility data to collect below the carriageway. Trunk mains and sewers often stayed in place, so a cross-road trench or bore still needs a full-width scan.
Is it safe to work near the metro?
Yes, provided the survey is planned around the metro's own structures and diverted services. The Purple Line runs along MG Road, and Majestic's Kempegowda station is the main interchange. The Pink Line's underground section through this part of the city has been under construction. Each metro construction site left fresh backfill that blurs the GPR data, so we request diversion drawings and scan tightly near structures.
Routes that leave the core heading for Hebbal or the airport road continue on our Mezux Bengaluru North City Corporation utility survey page.
What conditions will you meet, street by street?
Pete, Cantonment, CBD and metro-side streets each call for a different mix of tools.
| Central street type | Usual finds | Our method |
|---|---|---|
| Chickpet and other Pete lanes | Ageing water and sewer pipes, shop connections, cables dropped from overhead | Radar pushed by hand at dawn, extra pits |
| Old Cantonment roads | Masonry drains, cast-iron water mains, roots of old trees | Scans crossed at right angles, covers opened |
| TenderSURE roads in the CBD | Footpath duct banks, legacy mains under the carriageway | Duct chambers inspected, radar across the full width |
| Streets beside Purple or Pink Line works | Newly shifted services, loose backfill | BMRCL diversion sheets, close grid by the structures |

Does satellite positioning work in the Pete lanes?
Not well, so the old market lanes are surveyed by total station, with DGPS only at the open ends. Chickpet and Balepet lanes are narrow between tall shopfronts, and satellite fixes drift off the walls. Our surveyors set DGPS control points in Bengaluru on wider roads nearby, then run a closed total station traverse through the lanes. Each manhole, valve box and detected cable is shot from that traverse with levels, so the lanes fit the city grid.
What does the survey cost, and how do we start?
₹24 per metre for a standard scan or ₹32 per metre with an L-section, with a minimum of ₹1,00,000 per Bengaluru project. Mobilisation, if chargeable, is shown in the quotation. Long orders get a whole-order discount of 25% above 100 km, 40% above 500 km and 50% above 1,000 km, and GST is extra. Central jobs are often short but slow: 1.8 km of Pete lanes falls under the minimum, while 5.5 km of CBD footpath scanning comes to ₹1,32,000 before GST. A city-resident surveyor can open a central job once slots are agreed, never more than one business day after the order.
Since 2003 our own employees and radar have handled every job, with nothing sub-let. Bengaluru Central City Corporation has engaged us through direct work orders. Firms laying underground utilities in the core, their consultants and the utilities book us too. For utility mapping in the Central corporation, send the ward name, a route sketch and any records, then request a site visit for Bengaluru.
Frequently asked questions
Will scanning in Chickpet or the other Pete markets hold up trade?
Rarely. The crew works early morning or late evening, with hand-pushed radar narrow enough to pass between stalls and parked two-wheelers.
Do you cover areas beside the Central corporation?
Yes. One crew can carry a ground penetrating radar survey into neighbouring corporations. See survey coverage in Bengaluru details.
Can the drawing sit on surveyed coordinates?
Yes. We set out control points first; this is how our DGPS survey works.
Are abandoned pipes shown on the drawing?
Yes, when we detect them. They are labelled as likely disused, since only the owning agency can certify that a pipe or cable is dead.
Who gives permission to dig in the Central corporation?
In most cases the corporation that owns the road. The contractor or line owner applies, and our utility maps support the application.
When does the drawing for a central route arrive?
For a short central route, within several working days of scanning. Dense streets can take a little longer to draw up.
