Okhla Industrial Area, New Delhi — 67 KM OFC Corridor
Quick AnswerMezux Touch delivered a 67 kilometre optical fibre corridor across the Okhla industrial and commercial belt in South Delhi, covering GPR survey, permissions, trenchless crossings and fibre installation, completed under multi-authority compliance and below approved capital expenditure.
An industrial estate that became commercial
Okhla was laid out for manufacturing and has substantially converted to offices, showrooms, studios and institutional use, without the industrial servicing beneath it being removed.
Heavy three-phase feeds, process water, compressed air runs and effluent connections from earlier occupants remained in place, capped or simply built over, and current occupiers could rarely account for them.
Those inherited services were the principal survey finding along the corridor, and they were reported as unverified rather than dead, because on plots with this history nobody can reliably say which is which.
Working hours in a mixed belt
Commercial frontage trades late and industrial units run shifts, so a single working window did not exist across the corridor.
The programme was sectioned by land use rather than by geography — commercial stretches worked early morning, industrial stretches against occupiers' shutdown periods, and arterial approaches at night with traffic management.
What the eastern stretches added
Ground toward the river carried noticeably higher moisture, which reduced achievable radar depth along those sections. The survey stated that by section rather than giving one figure for the corridor.
Those stretches also brought an additional consideration near the river margin alongside the municipal and estate approvals, and the file for it was opened before the corridor work reached that point.
It is a small part of 67 kilometres and it shaped a disproportionate share of the sequencing, which is usually how river-adjacent work behaves.
What was delivered
67 kilometres of optical fibre corridor with survey ahead of every stretch, HDD crossings, duct installation, blowing and splicing, and restoration closed out with deposits released.
The corridor was completed under multi-authority compliance and below approved capital expenditure, largely because routes were optimised against survey findings before construction rather than during it.
The lesson we took from it
On converted industrial land the current occupier is usually not the right person to ask about what is buried. The plot's trade history is a better guide than its current signage.
We now ask for that history at scoping on every industrial plot survey, and it came directly from this corridor.
Frequently asked questions
Inherited industrial servicing — three-phase feeds, process water, compressed air and effluent connections from earlier occupants, capped or built over and unaccounted for by current occupiers.
Because on plots subdivided and re-let repeatedly, nobody can reliably say what was decommissioned and what was simply left in place.
By sectioning the programme by land use — commercial stretches early morning, industrial against shutdown periods, arterial approaches at night with traffic management.
Yes. Higher moisture on the eastern stretches reduced achievable radar depth, and the survey stated that by section rather than giving one figure for the whole corridor.
We now ask for a plot's trade history at scoping on every industrial survey. The current occupier is rarely the right person to ask about what is buried.

67 kilometres of optical fibre corridor delivered across the Okhla industrial area in South Delhi, under multi-authority compliance and materially below approved capex. Okhla's particular difficulty is that it has been converting from manufacturing to commercial use for years, which means a corridor here crosses two subsurface networks: the industrial one that fed the original occupants, and the commercial one added above it.
The conditions that shaped delivery
Estate phases were developed at different periods, so made ground depth and servicing age both varied along the route and calibration had to follow. Process and effluent servicing from units that had closed or converted remained capped or built over, indistinguishable from live plant at the surface. Frontage servicing added during commercial conversion sat shallow and largely unrecorded. Approvals ran through the corporation zone, the industrial development body, the power utility and the metro corporation on its alignment.
What the corridor demonstrates
That on a converting estate the useful survey output is the separation between confirmed live servicing, inherited industrial servicing marked unverified, and probable process routes — merging them would have been tidier and considerably more dangerous. That calibrating by estate phase rather than once across the route is what kept depth figures comparable end to end. And that delivering below capex here came from not encountering surprises, which followed from surveying first rather than from working faster.
Beyond the basics
What is unusual about Okhla? It is converting from manufacturing to commercial use, so a corridor crosses two subsurface networks: the industrial one beneath and the commercial one added above.
How were inherited services handled? Reported as unverified rather than dead, in their own schedule. Several were found capped but indistinguishable from live plant at the surface.
Why calibrate by estate phase? Because phases were developed at different periods, so made ground depth varies along the route. One calibration would have made the depths incomparable.
How was below-capex delivery achieved? By not encountering surprises, which followed from surveying ahead rather than from working faster or reducing scope.
Which authorities were involved? The corporation zone, the industrial development body, the power utility and the metro corporation on its alignment, opened in parallel.
Terms used on this page
Estate phase — a numbered development stage of an industrial area, each serviced at a different period. Converting estate — industrial land changing to commercial use, leaving original servicing in the ground. Unverified servicing — a line that appears disused but has not been confirmed dead by its owner. Calibration by phase — re-establishing radar velocity where ground conditions change along a route. Process route — pipework carrying industrial fluids, reported separately from general utilities.
