Enterprise and data centre fibre
Enterprise Fibre Route Survey for Tata Comm & Sify
Two routes into the same building are only diverse if they stay apart underground. We check that before the duct goes in.
Quick AnswerAn enterprise fibre route survey scans the last-mile path into an office, bank branch or data centre before ducts are laid. It finds existing services, checks that two "diverse" routes stay apart, and gives the HDD crew a clash-free entry. Rates start at ₹24 per metre; you can also see telecom operator projects of other kinds.
What is an enterprise fibre route survey?
An enterprise fibre route survey is a GPR scan of the last-mile path between a carrier's network and a business site. It marks every buried service on that path with depth, confirms building entry points, and checks physical separation where the customer has paid for two independent routes. As a survey method, ground penetrating radar (GPR) fits the last mile well. Short radar pulses enter the footpath, and the receiving antenna catches the echo from each duct or pipe as the cart rolls.
Enterprise carriers such as Tata Communications and Sify sell connectivity that businesses cannot afford to lose: leased lines, MPLS networks and links between data centres. Tata Communications grew out of VSNL, the former state overseas carrier, after the Tata group took a controlling stake in 2002, and adopted its present name in 2008. Sify Technologies, based in Chennai, runs data centres and enterprise network services and was among the first Indian internet companies listed on NASDAQ. For carriers like these, the last few hundred metres matter as much as the backbone.
Why does route diversity need a survey?
Because two ducts drawn on separate streets can still meet at the same pit, the same culvert or the same building wall. A customer buying a diverse service expects that one excavator cannot cut both links. That promise only holds if the paths stay physically apart all the way to the building.
The survey shows where they come close. The usual weak points are:
- the last 20–30 m before the building, where both routes often aim for the same entry;
- a single road crossing that both routes use because it is the only easy one;
- a shared culvert or drain crossing on a business park's internal road;
- an existing third-party duct bank that both routes are planned to run beside.
We mark the separation along each route and flag any stretch where the two are closer than the customer's specification.
Which sites do we survey most often?
Business parks, bank branch networks and data centre campuses. Each brings a different pattern of buried services.
- IT and business parks. Internal roads carry the park's own water, sewer, power and fire mains, plus ducts from several carriers. The estate office holds drawings, but they are rarely current.
- Bank and retail branches. Many short entries in different towns, each crossing a footpath and sometimes a road. These are best batched.
- Data centre campuses. Large cable entries, high-voltage feeds, generator fuel lines and chilled water pipes, in clusters around Mumbai, Chennai, Hyderabad and Noida. Precision matters most here.
Carriers with subsea cable landing stations in Mumbai and Chennai also need short, protected land routes from the beach to the station. The same scanning approach applies to that optic fibre.

How does the survey shape the HDD plan?
It fixes the entry and exit pits and the depth of each shot so the bore passes every service with clearance. Most enterprise entries cross a footpath, a kerb and a road edge in a short distance, which suits a single HDD shot. The scan decides where that shot can start without hitting a water connection or the building's own cables. You can read about HDD route survey work and how the bore profile is set.

How precise is the separation we report?
Horizontal positions are good to a few tens of centimetres; depth is an estimate that depends on soil conditions. For diversity checks, the horizontal figure counts, since both routes sit at a similar depth.
We measure each route's centre line from the data collection, tie it to coordinates, and plot the distance between the two at regular intervals. A simple chart on the drawing shows separation against chainage, with any section below the agreed figure shaded. That makes it easy for a carrier's design team to see where a route needs to move, and for the customer to see what was checked.
Two limits are worth knowing. First, a survey records the ground on the day; a third party can lay a new service across both routes later. Second, GPR sees the duct, not the fibre inside, so the survey cannot tell which customer's cable runs in which duct. Carriers close that gap with their own records and a tracer test at chambers.
What does an enterprise route survey cost?
₹24 per metre for a standard scan and ₹32 per metre for an L-section, plus GST. Minimum order: ₹50,000 in Delhi NCR, ₹1,00,000 elsewhere. Whole orders over 100 km get 25% off, over 500 km 40%, and over 1,000 km 50%.
- Two diverse entries of 1.8 km each into a Noida data centre campus: 3,600 × ₹24 = ₹86,400 plus GST.
- A batch of 40 bank branches averaging 250 m each: 10,000 × ₹24 = ₹2,40,000 plus GST.
- A 120 km metro ring: the 25% slab brings the rate to ₹18, so ₹21,60,000 plus GST.
What should you send us?
The two route options, the building entry points and the separation the customer requires. If the site is inside a business park or campus, include the estate office contact so we can arrange access and see any drawings they hold.
Access in such places is tightly controlled, with security passes, escorts and fixed hours. Tell us at booking and we plan around it. Night work in campuses is possible where the facility team allows it.
Tata Communications and Sify Technologies have each engaged Mezux Touch on direct orders for building-entry and route scans. Company names on this page are used only to describe the type of work; all trademarks belong to their owners. We also work for the carriers' contractors and for facility owners, with our own crews, and the drawings add to each site's underground utility mapping. To fix scope and dates, ask for a quotation.
Frequently asked questions
Can you prove two routes are diverse?
We can show their measured separation along the surveyed length and flag close points. Whether that meets the contract is for the carrier and customer to decide.
Do you scan inside the building?
Our main work is outside, up to the entry. For core cuts through slabs or walls inside, a high frequency antenna scans the concrete first.
Is a single branch entry too small to order?
The minimum order applies, so most carriers group branches by city into one visit. Our price list sets out what we do: GPR survey rates, minimums and slabs.
How do you work in a live data centre campus?
Under the facility team's permit and escort rules, with short scans planned in advance. A GPR survey there also checks for each buried object near the entry pits.
Can you find a carrier's existing duct for reuse?
We can locate ducts and show their route and depth. Who owns them and whether they can be used is a matter for the owner.
What format suits a carrier's planning tools?
DWG, PDF and KMZ as standard; shapefiles on request.
