Utility Mapping for IT Park Estates, Carriers and Retrofits
Many owners, many carriers, one map: we trace what each of them buried so EV bays, new towers and fibre runs go in without outages.
Quick AnswerUtility mapping for IT park estates locates the developer's water, sewer, fire and power networks, every carrier's telecom ducts and the tenants' own cables. All of them go on one coordinated map with depths and certainty. It comes before EV bays, a new tower, a solar car park or new fibre. Parks that also house server halls start by booking a data centre site survey.
What makes utility mapping for an IT park different?
The number of owners: the developer, the facility manager, the power utility, half a dozen carriers and dozens of tenants, with no single drawing showing them all. The survey brings those layers onto one base map, so the facility team can approve a trench with confidence instead of asking around.
India's large IT clusters grew fast and in phases over fifteen or twenty years, from Gurugram's Cyber City and the Noida expressway to Whitefield, HITEC City and Hinjewadi. Facility management contracts have changed hands since. Some parks are notified special economic zones under the SEZ Act, 2005, with their own approval channel for new works. The result is good surface drawings and patchy utility records below ground.
Which jobs trigger the survey?
Retrofits on a live estate, where the new work must thread between existing services.
- EV charging bays in car parks and basements, each fed from the nearest panel or a new transformer.
- A new office tower on a reserved plot, with foundations close to existing ring mains.
- Fibre for a new tenant, with a carrier trenching from the gate or meet-me room.
- Solar car park canopies, whose column foundations land all over the parking area.
- DG and transformer upgrades, with new cable routes to existing switch rooms.
- Landscaping and podium works, where planters and tree pits are dug into ground full of services.
The scope differs, but one rule holds: survey the trench or footprint and a margin around it for underground utilities, not only the line on the drawing.
EV charging is the fastest-growing trigger. A car park that looks empty is often crossed by existing utility runs: street-light cables, irrigation lines, storm drains and a carrier route from the gate. Each charger needs a cable from a feeder pillar, and a fast-charger cluster may need its own transformer and HT feed. Planning those routes on a mapped car park can turn a two-month installation into a two-week one.
Who owns which line?
Mapping is half the job; labelling each line with its likely owner is the other half, because that owner must be told before work starts.
| Owner | Typical services | Where to look |
|---|---|---|
| Developer or facility manager | Water, sewer, storm drains, fire ring, internal HT and LT network, street lights | Ring roads, between towers, under podiums |
| Power utility | Incoming feeders to the park substation | From boundary road to substation |
| Telecom carriers | Duct routes, handholes, entry to meet-me rooms | Along the gate road and building fronts |
| Tenants | Private fibre between towers, DG cables, UPS links | Short runs between their own buildings |
| Unknown or abandoned | Old construction power, superseded ducts | Anywhere; flagged for confirmation |
Table note: record each retrofit before the trench is closed. See getting an as built survey done right for how that keeps the park map current.
Ownership labels also change how a park handles a dig. If a planned EV trench crosses two carriers' ducts and a tenant's fibre, the facility team can notify exactly those parties. It can then agree protection as part of utility coordination and book their representatives for the day. Without labels, a general email goes to everyone. In our experience the worst strikes on business parks hit a third party's duct that nobody on site knew about. Utility mapping for IT park retrofits is mostly about finding those.
Reading the ground: what radar shows
A ground penetrating radar scan does not draw pipes; it records echoes. Each pipe or duct crossed at an angle appears as an arch-shaped curve whose top marks the top of the object. Depth comes from the echo's travel time, calibrated for the soil's wave speed. Several arches side by side at one depth point to a duct bank, and a flat bright band is often a slab, trench base or water table.
Radar is therefore paired with other geophysical methods and physical evidence. Locators follow metallic utility lines along their length, chambers are opened to count ducts, and a sonde pushed through an empty duct shows its route. On podiums and in basements, where reinforcement fills the radar picture, drawings and chambers carry more weight, and the report says so.
How the survey runs on a busy estate
Through the facility team's work-permit system, in short windows that suit traffic and tenants. Ring roads and car parks are scanned early morning or at weekends, and forecourts outside peak arrival hours. During utility locating, carrier handholes are opened only with the facility team present, and live equipment is never touched. The crew logs daily coverage on a plan you can see. A full map of a 20 to 30 acre park takes one to three weeks of field work, depending on podium area and blocked zones.
What you receive
A coordinated CAD and GIS map with owner, depth and one of four quality levels for every line, plus a list of anything unresolved. See a closer look at CAD and GIS utility mapping for layers and formats, and GPR survey deliverables explained for what the report includes. A park with a server hall can add a denser resilience check: our page on how underground utility mapping for a data centre works describes that extra step.
Rates and an example
The estate is billed per metre of radar scan line, and a minimum order applies to small retrofits. Standard scanning is ₹24 per metre; where we also draw a longitudinal section along a route, it is ₹32 per metre. Small jobs carry a minimum of ₹50,000 in Delhi NCR and ₹1,00,000 in other cities. Multi-park programmes get 25% off above 100 km, 40% above 500 km and 50% above 1,000 km. All rates exclude GST.
Example: clearing EV routes across three car parks needs about 3 km of scan lines, so 3,000 × ₹24 = ₹72,000. A full map of a dense 25-acre park might need 25 km, at ₹6,00,000. In Delhi NCR the crew reaches site the same day or within 1 working day. In other cities, a team member living there begins at once, within 1 working day at most, and any mobilisation or travel cost, if applicable, is shown in the quote.

Frequently asked questions
Can you tell which carrier owns a duct?
Often, from markings on handhole covers, duct colours seen in chambers and carrier route plans. Where it cannot be confirmed, the duct is labelled unknown owner.
Will tenants' services be disrupted?
No, the survey is non-invasive; only trial pits, hand-dug or vacuum excavated, involve digging, and those are agreed in advance with the facility team.
Can you scan basement car parks?
Yes, for services embedded in or immediately below the slab. Deeper services under a basement raft are beyond reach in most cases and are taken from records.
How accurate are radar depths?
Typically within about 10% of depth when calibrated on site, better where a trial pit or chamber gives a known depth.
Do carriers need to be informed before trenching?
Yes, along with registering the dig on the national platform; read more on Call before You Dig in India for the steps.
Can the map be shared with contractors?
Yes, we can issue a contractor version of the utility data with only the layers they need, keeping tenant details private.
