Slab and wall opening approval is the structural review required before creating or enlarging an opening that may affect a load-bearing slab, wall, beam or other structural element. Building Approval supports structural verification, strengthening design, NOC follow-up and authority submission across Dubai.
Slab and wall opening approval in Dubai is the structural review required before creating or enlarging an opening that may affect a load-bearing slab, wall, beam or other structural element.
The engineer normally verifies the existing structure, assesses the opening and its effect on load paths, designs any trimming or strengthening, and coordinates authority/developer approval before cutting starts.

Slab & Wall Opening Approval may be relevant to individuals and organisations planning related building or modification works.
A quick look at the services we typically support under Slab & Wall Opening Approval, and the kinds of projects they usually apply to.
Support built around your project's actual technical and structural scope.
Review existing structural drawings against the proposed opening.
Survey and verify the actual structural element on site.
Coordinate rebar/PT/service scanning where reinforcement is uncertain.
Assess opening feasibility and the modified load path.
Design trimmer beams and strengthening around the opening.
Coordinate temporary support and the cutting sequence.
Coordinate the architectural/MEP overlay with the structural design.
Coordinate authority/developer submission and comment closure.
Some projects require a developer/landlord NOC before authority submission; others require a design approval before a construction permit can be issued — the final sequence is subject to the competent authority and project-specific prerequisites.
Confirm whether the proposed element is structural and identify the authority route.
Obtain existing structural drawings and survey actual conditions.
Locate critical reinforcement/services before finalising the opening.
Analyse the modified load path and define strengthening/trimming.
Prepare opening details and cutting/temporary-support notes.
Secure owner/developer NOCs.
Submit the structural modification package.
Execute controlled cutting to approved details and complete required inspection/record updates.
The exact document and drawing requirements may vary depending on project type, property, jurisdiction, activity and current authority requirements.
Small openings away from critical structural zones can be simpler than major stair openings, load-bearing wall removals or work in post-tensioned slabs. The programme should include investigation/scanning, engineering, NOC, authority review and controlled execution. No universal number of working days applies across Dubai jurisdictions.
Costs depend on investigation, scanning, calculation complexity, strengthening, temporary works, authority/developer fees and specialist cutting. A small service penetration and a large stair opening are not comparable — authority fees should not be quoted until the jurisdiction and permit category are confirmed.
Cutting starts before confirming whether the wall/slab is structural
Opening location conflicts with beams, columns or post-tension tendons
Rebar scan is performed after design rather than before final detailing
MEP contractor changes the opening size after structural approval
Temporary support is omitted from a critical removal sequence
Approved drawings do not reflect actual site conditions
Building Approval coordinates the slab & wall opening approval workstream with the rest of the project programme.
Dubai-specific jurisdiction screening before detailed submission work begins.
Coordination between architectural intent and structural design requirements.
Clear separation of authority approval, developer/landlord NOC and specialist approvals.
Comment-resolution support focused on keeping drawings and calculations on the same revision.
We work directly with Dubai's regulatory authorities, free zones, master developers and utility providers — matching every project to the right approval pathway, documentation and compliance requirements from the very first submission.
Send us your project location, proposed opening location and any existing structural drawings — we'll review the likely approval route and identify what's required before cutting starts.
