LDA Lucknow GPR Survey for Schemes, Townships and Widening
Utility sweeps and base maps for Lucknow Development Authority schemes, from new townships to settled colonies due for widening.
Quick AnswerFor a plot layout on Mohan Road or a widening in Gomti Nagar, an LDA Lucknow GPR survey first sets down the depth and route of every buried line. New townships need a clean base and older colonies need records corrected, and ground penetrating radar (GPR) serves both. For mapping a whole scheme digitally, read about smart city underground mapping.
What is an LDA Lucknow utility survey used for?
It finds and records the buried services inside a Lucknow Development Authority scheme or along its roads, so new construction, widening or retrofitting does not strike them. A ground penetrating radar survey gives designers a reliable base, contractors a dig plan and the authority's engineers a record that matches the ground.
Set up in 1974 under the Uttar Pradesh Urban Planning and Development Act, 1973, the authority has built much of modern Lucknow. Its schemes range from settled colonies such as Gomti Nagar to newer townships like Anant Nagar on Mohan Road and Prabandh Nagar. Each is at a different stage of life, and that stage decides the scope.
How do services in an LDA scheme change over the years?
They start neat and get messier with every decade, as each owner adds lines without updating anyone else's drawing. A new scheme lays water, sewer, drains and power to a common plan. Then houses add connections, telecom firms pull fibre, gas arrives, roads are raised, and many colonies pass to the Nagar Nigam. Twenty years on, the original layout is still on file and seldom correct.
What does a new LDA township need?
A clean base before the first trench, because land that was farmland a few years ago often hides field pipes and through-cables. Edge townships such as those on Mohan Road cross old irrigation lines, tube-well cables and long-distance fibre that no office has drawn. A sweep before layout costs far less than a stopped trench. It also lets designers route new trunk services clear of anything that must stay, such as a high-voltage cable crossing the site.
On a greenfield scheme the sweep is often ordered with a topographic survey for Lucknow sites, so planners get levels, plot edges and buried lines in one frame. On large townships that base can grow into a digital record of services as built, the approach outlined on read about smart city underground mapping.
Will the survey turn up mains and sewers missing from the LDA layout?
In most cases, yes, since radar sees pipes of any material and the locator follows metallic ones. In older colonies we find replaced mains beside the originals, sewers shifted during road raising and house connections at odd angles. These underground utilities rarely match the layout until they are identified and mapped again. Plastic pipes in wet clay remain the hardest target. Our work on pressure mains and gravity sewers is on our page with more on underground pipeline detection.
How do you work in a lived-in colony?
Quietly, in agreed hours, with the residents' association told in advance. Settled colonies have cars along both kerbs, gated lanes, ramps over drains and gardens over the service strip. We walk the route first, ask for vehicles to be moved from key crossings and use a hand-pushed radar cart that shows each trace in real time. Covered chambers are noted, not broken, and paint ticks wear off within weeks.
Which survey suits which stage?
The scope follows the scheme's age and the job in hand.
| Where the scheme stands | Our suggested scope | Key deliverable |
|---|---|---|
| Freshly acquired farmland | Sweep for field pipes and cables, with levels | One base sheet for planners |
| Trunk services going in | Each open trench recorded before backfill | As-laid layer that grows with the township |
| Widening in an older colony | Radar corridor, L-sections where lines cross | Design sheet and a crossing register |
| New drains or sewers retrofitted | Standard radar run, chambers lifted to check | Route with depths |
| Road now with the corporation | Scope matched to a Nagar Nigam road-cut file | Sheet for the road-cut application |
Table note: drawings come as AutoCAD and GIS. That final case is handled from the corporation's end; read what you receive from a Lucknow Nagar Nigam utility survey.
How does Lucknow's ground behave?
Deep Gomti alluvium: soft to dig, variable for radar. A GPR antenna sends pulses downward, and reflected signals return wherever the electromagnetic properties of the ground change, as at a pipe wall. Dry sand gives clear images well below most services, while silty clay near the river cuts the reach. The first pass on each site tests that depth for utility detection, and the drawing quotes it. Our Lucknow team is described at GPR survey in Lucknow at a glance; for approvals there is our short utility survey guide for Lucknow.
What does an LDA survey cost?
Township-scale orders earn slab discounts on a per-metre rate, and every project has a floor.
- Standard GPR scan: ₹24 per metre
- L-section with depth profile: ₹32 per metre
- Minimum order: ₹1,00,000 per project
- Whole-order discount: 25% above 100 km, 40% above 500 km, 50% above 1,000 km
Scanning 22 km of township roads at the standard rate costs ₹5,28,000. A 3 km widening stretch with L-sections is ₹96,000 and is billed at the minimum. GST is added, and getting the team to site is priced separately if applicable. Our engineer lives in Lucknow, so the first scan on LDA land comes the same day, or one business day at most.
What happens to the survey when a colony is handed over?
When LDA hands a colony to the Nagar Nigam, the new owner wants to know where every line went. We build that record on DGPS pillars for Lucknow schemes at the scheme edge and a total station for road and plot detail inside it. Lines found by radar, and pipes laid during construction, sit on that grid. The hand-over file shows each main and sewer against plot numbers, with manhole levels, so a gang can later find a valve from coordinates.
Working with LDA and the firms on its schemes
Engineers employed by Mezux Touch, pushing radar the company owns. Its utility survey record goes back to 2003. It keeps 58 GPR systems, never passes site work to a sub-contractor and holds ISO 45001, 14001 and 9001. These engineers have carried out GPR surveys on LDA projects on work orders from the authority. They also work for township developers, civil contractors, planning consultants and service providers.

Frequently asked questions
Does LDA hand its colonies over to the Nagar Nigam?
Many settled colonies are maintained by the Nagar Nigam after handover, while LDA keeps others. Check with the authority which body holds your road before filing a road-cut request.
Can you record services while a township is being built?
Yes. We survey each trench on the construction site before backfill and build an as-laid layer as the scheme grows.
Will you find old irrigation pipes on new land?
In most cases. Radar and a passive locator sweep pick up field pipes and cables on open ground, and the data collection covers the whole plot.
Do you also do levels and boundaries?
Yes. A topographic survey can be run alongside, sharing the utility layer's coordinates.
Which Lucknow areas do you cover?
The whole city and its fringe. See survey coverage in Lucknow details.
