RTA requires details on trench dimensions and depth, how nearby utilities will be protected during excavation, backfill and reinstatement plan, and site safety measures — particularly important since trial trenches are dug precisely because the utility layout isn't fully confirmed yet.
RTA Trial Trenches NOC Dubai | Utility Investigation Excavation Permit
Before major construction near a public road, contractors often need to dig trial trenches to verify the exact location, depth, and condition of existing underground utilities — this exploratory excavation requires its own RTA NOC before any digging starts. Structural Solutions manages RTA trial trenches NOC applications across Dubai.

Why Trial Trenches Need Separate Approval
Trial trenches are typically dug before a project's main structural design is finalised, to confirm utility positions shown on drawings actually match what's underground — RTA reviews this separately from your main construction NOC since it happens earlier and carries its own excavation safety requirements.

RTA Trial Trenches NOC Dubai at a Glance
| Step | Who | What happens |
|---|---|---|
| 1 | Structural engineer | Surveys the road frontage and prepares drawings in DLTM coordinates for RTA. |
| 2 | Master developer (where applicable) | NOC for works in the community. |
| 3 | RTA | Reviews the drawings and issues the NOC or permit. |
| 4 | Service authorities | DEWA and telecom clearances where services are affected. |
| 5 | RTA | Inspection and reinstatement check after works. |
Documents Required
- Affection plan / site plan
- Owner or company documents
- Survey-based drawings in DLTM coordinates
- Developer NOC (in master-developer communities)
- Existing services information, where available
Key Technical Rules
- Approval before road works: any work in the road reserve needs RTA approval first.
- DLTM drawings: RTA reviews drawings in DLTM coordinates.
- Utility clearances: DEWA and telecom services are checked where they run under the works.
- Work zone safety: works follow RTA work zone traffic management rules.
- Reinstatement: the road, kerb and footpath are reinstated and inspected.

RTA Trial Trenches NOC — FAQs
Do I need this before every construction project?
Only where utility positions need verification before finalising design — confirmed during initial assessment.
How is this different from a general excavation NOC?
Trial trenches are specifically for investigation, not the main construction excavation, and are reviewed with that purpose in mind.
What do you need from me to get started?
Your plot or unit details, title deed or affection plan, any existing drawings and a short description of the works — we confirm the approvals needed and prepare the submission.
What happens to the trenches after investigation?
They're backfilled and reinstated per your approved method statement.
