Mezzanine Floor Approval Dubai 2026

A missing slab punching shear check in the structural calculations is the most common engineering review rejection for mezzanines.

Punching shear is the failure mode where a concentrated load — a mezzanine column landing on an existing slab — pushes through that slab rather than being carried by it. It is a localised failure at the column point, and it does not show up in a general load capacity calculation. A submission can demonstrate that the slab carries the total added weight and still be rejected, because the reviewing engineer is looking for the check at each column position specifically.

If your structural consultant has produced calculations without an explicit punching shear check at every mezzanine column location, the submission will come back. This is the single highest-value thing to verify before anything is lodged.

The mandatory document set is:

• Tenant's trade licence
• RERA (Ejari) or title deed — proving your right to alter the unit
• NOC from building management — the landlord or facility manager must consent before the authority will review
• Plot drawings and Plot Affection Plan
• Structural Stability report

The structural stability letter confirming the building's ability to support the mezzanine is the document that carries the most weight, and the one most often produced last. It has to come from a qualified structural consultant assessing the actual existing building, not a generic template. Where the original building drawings are unavailable — common in older Al Quoz and Ras Al Khor warehouses — that assessment may require an on-site survey first, which is a lead time worth discovering early rather than late.

Mezzanine submissions require both the current and intended condition, not just the proposal:

• Existing and proposed floor plans
• Flooring layout
• Ceiling layout
• Furniture layout
• Sections
• Structural details
• MEP drawings
• Fire safety plans, including sprinklers

Sections matter more here than in a flat fit-out, because the reviewer is checking headroom above and below the mezzanine deck and the relationship to the existing sprinkler array. Adding a deck beneath an existing sprinkler system frequently means sprinklers are now required underneath it as well — which is an MEP and Civil Defence consequence, not just a structural one.

Inserting a mezzanine changes the fire strategy of the space. Approval requires proper placement of fire alarms, smoke detectors, sprinklers, and emergency exits for the new configuration.

The practical issues that arise repeatedly:

• Sprinkler coverage below the deck. The existing overhead array no longer reaches the floor area you have just covered over
• Detection on the mezzanine level. Smoke detection has to cover the new occupied level, not just the warehouse volume
• Means of escape from the mezzanine. Travel distance and exit provision are assessed from the deck, and a single stair in the wrong position can fail the review
• Racking interaction. Where racking sits under or beside a mezzanine, the combined arrangement is what gets assessed, not each element separately

This is why mezzanine and racking work should be submitted as one coordinated package where both are planned. Splitting them into separate applications tends to produce contradictory fire requirements.

The reviewing body follows the plot, not the business:

• Dubai Municipality — mainland industrial and commercial plots, including Al Quoz, Ras Al Khor and Dubai Investments Park
• Trakhees — Nakheel and DP World master communities
• JAFZA — Jebel Ali Free Zone units, with EHS and Trakhees CED coordination
• DDA — TECOM zones

Submitting to the wrong authority is a pure time loss: the application is not transferred, it is closed, and you start again with a different drawing format. Our racking and mezzanine approval team confirms the governing authority against the plot before any drawing work begins, and prepares the structural package with the punching shear check included from the outset.
