Information Center
Understand the work that happens beneath the surface.
Knowledge for better projects
Underground infrastructure is technical and regulation-heavy. This Information Center explains the key processes in plain language — so you can plan with confidence and understand exactly what Mezux delivers at each stage.
What is GPR survey?
Ground-Penetrating Radar survey uses radar pulses to detect and map utilities buried underground — pipes, cables and ducts — before any excavation. It reduces the risk of damaging existing assets, speeds up approvals, and produces field-verified as-built records.
What is HDD (Horizontal Directional Drilling)?
HDD is a trenchless method of installing ducts and conduits underground by drilling a controlled bore beneath the surface. It allows crossings under roads, railways and water bodies with minimal surface disruption and faster restoration.
How does Right of Way (RoW) work?
RoW is the legal permission to lay infrastructure along or across a route. It involves coordinating with authorities such as PWD, MCD, NHAI and municipal bodies. RoW is where most projects stall — and where Mezux's in-house liaison team is fastest.
What does OFC work involve?
Optical Fibre Cable work covers HDPE duct laying, cable blowing and pulling, and fusion splicing — the steps that turn empty ducts into a live, tested fibre network for backbone and last-mile connectivity.

This section collects the explanatory material a client or engineer may need before commissioning underground work: what each survey method establishes and where it fails, how quality levels grade utility information, what a permission file actually contains, and the terminology that appears in our drawings and reports. It is reference rather than promotion, and it is written to be usable by someone evaluating any contractor rather than only us.
How the material is organised
Method explanations sit on the service pages, each stating the technique's limits alongside its capability. Location-specific ground data sits on the ninety city pages under GPR Survey, covering achievable depth, authorities and access for each market. Permission process detail sits on the RoW clearance pages by city. Sector standards sit on the six sector pages. Practical articles on decisions — trenchless versus open cut, evaluating contractors, why files stall — sit under Insights. Every page carries an extended reference block with a glossary specific to that subject.
What to read before commissioning a survey
Three things, in order. First, what the method can establish on your particular ground, which is on the relevant city page rather than in a general specification. Second, what drives the price, so two quotations can be compared meaningfully rather than by rate alone. Third, what the deliverable will actually contain, because a marked-up plan and attributed CAD with a residual risk register are different products at different prices and both are described as a survey.
Beyond the basics
Is this material contractor-neutral? It is written to be usable by someone evaluating any contractor. The questions it suggests asking are ones we would have to answer too.
Where is the ground data for our city? On the relevant page under GPR Survey. Each covers achievable depth, authorities and access constraints for that specific market.
What should we read before commissioning? What the method can establish on your ground, what drives the price, and what the deliverable actually contains. In that order.
Is there a glossary? Each page carries one specific to its subject, because the terms that matter on a gas network differ from those on a metro alignment.
Can we cite this material? Yes, with attribution. It is used in tender documentation and internal training, which is a better use of it than ranking for a keyword.
Terms used on this page
Quality level — a SUE grading describing how utility information was obtained. Residual risk register — a schedule of what remains unknown after survey, for adoption into a project register. Attributed CAD — a drawing where each feature carries data such as depth, method and confidence. Reference material — explanatory content intended for evaluation rather than promotion. Deliverable — what is actually issued at completion, which varies widely between contractors.
