Execution · Warehouses, industrial and villa structures

Steel works built to the approved structural design

For owners and tenants who need a mezzanine, canopy, shed or steel extension built legally. We coordinate fabrication and erection so the steel matches the approved structural drawings, passes inspection and is covered by the completion paperwork.

Steel is fast to put up, which is exactly why it is so often put up without approval. A mezzanine bolted into a warehouse over a long weekend adds floor area, changes fire escape distances and puts new loads on the slab. To the authority it is a building alteration, not furniture.

Structural steel in Dubai is a regulated activity at both ends. The design has to be approved by the authority for the plot, and the company that fabricates and erects it has to be licensed for steel contracting. Between the two sit inspections, test records and, at the end, the completion stage that makes the structure part of the building's approved record.

This service is for clients who want the execution done in line with that. We coordinate the steel works so they follow the approved structural drawings, and we keep the link to the approval intact from shop drawings to completion.

How steel contracting is regulated in Dubai

Contractor registration and classification

Law No. 7 of 2025 regulating contracting activities created an emirate-wide contractor register run by Dubai Municipality, including free zones and special development areas. Contractors must work within their approved classification and capacity, and may not subcontract without prior approval.

Steel contracting as its own category

Dubai Municipality publishes licensing and evaluation criteria for "Building Contracting" and "Steel Contracting", alongside its activity classification and technical staff requirements.

Steel structure standard

Dubai Municipality's standard DMS 35:2020 sets requirements for steel structures and their components, covering organisations involved in their design, manufacture, fabrication and erection.

Building permit and inspection

New steel structures, extensions and mezzanines are construction works under Local Order No. 3 of 1999 and need a permit from the relevant authority before work starts.

Penalties under Law No. 7 of 2025 range from AED 1,000 to AED 100,000 per violation, doubled for repeats within a year up to AED 200,000, with possible suspension, downgrading or removal from the register. Contractors already operating had a year from the law taking effect to regularise. Our article on approved steel contractor requirements covers the detail.

From approved drawings to erected steel

The approval and the steel on site are connected by a chain of documents. If any link is missing, the completion stage stalls:

Document	Who prepares it	Why it matters
Approved structural drawings and calculations	Engineering consultant	Set member sizes, connections and loads. The authority approves these, not the fabricator's version.
Shop and erection drawings	Steel contractor	Translate the design into fabrication pieces. Must match the approved design; differences go back to the consultant.
Material certificates	Supplier · contractor	Show the steel grade used is the grade designed.
Welding and bolting records	Contractor · inspector	Show connections were made and checked as specified.
Fire protection records	Specialist applicator	Where the fire strategy requires protected steel, show the approved coating or boarding was applied.
As-built drawings	Consultant · contractor	Record what was built, for completion and future alterations.

For an existing building, the structure's capacity has to be confirmed before new steel is fixed to it. Our structural evaluation service covers that step.

Warehouse mezzanines are the most common request, and the most common source of trouble. A mezzanine adds floor area, so it affects the permitted built-up area, the fire strategy and escape routes. Civil Defence usually looks at protection, sprinklers below and above, and travel distances. See warehouse and industrial approvals and the guide to mezzanine fire safety.

Villa steel structures, such as a steel-framed room or large canopy, need the developer NOC and a building permit like any other extension.

Steel contracting process, stage by stage

Approval and design check

We confirm the permit and approved structural drawings are in place and that the building can take the new loads.

Our team · consultant

Shop drawings

Fabrication drawings are produced from the approved design and checked by the consultant before cutting starts.

Steel contractor · consultant

Fabrication

Members are cut, welded and coated in the workshop, with material certificates and weld records kept.

Steel contractor

Foundations and anchors

New footings or anchors into the existing slab, inspected before the steel goes on them.

Contractor · inspector

Erection and connections

Steel is erected, bolted or welded, and checked for alignment and tightness. Authority inspections are booked at the required stages.

Steel contractor · authority

Fire protection and completion

Fire protection, Civil Defence inspection, as-built drawings and the completion certificate close the job.

Specialists · authorities

Common problems with steel works

Building the mezzanine first. Regularising afterwards often needs structural checks, fire upgrades and sometimes partial removal.
Fabricator redesigning connections. Changes to the approved design must go back through the consultant.
Ignoring the slab. Point loads from new columns can exceed what the existing floor was designed for.
Unregistered contractors. Under Law No. 7 of 2025 contractors must be registered and work within their classification.
Missing fire protection. Unprotected steel where the fire strategy needs protection fails inspection.

How we help with steel contracting

Check the approval, the design and the building's capacity before fabrication
Coordinate fabrication and erection through a contractor registered for steel contracting, where we do not carry it out ourselves
Review shop drawings against the approved design
Track material, weld and fire-protection records
Book inspections and assemble the completion file

Steel contracting FAQs

Do I need a permit for a warehouse mezzanine?

Yes. A mezzanine is a structural addition that adds floor area. It needs a permit from the authority for the plot and usually Civil Defence approval for the fire strategy.

Can any steel fabricator build it?

No. Under Law No. 7 of 2025 contractors must be registered and classified, and Dubai Municipality has separate criteria for steel contracting. Ask for the contractor's registration before signing.

Can I legalise a mezzanine that is already built?

Often, but it takes an as-built survey, a structural check and fire-safety review, and may need upgrades. It is slower and costlier than approving it first.

Does steel need fire protection?

It depends on the building's fire strategy and the approved drawings. Where required, the approved coating or boarding must be applied and recorded.
