Structural
strengthening
& modification.

Beam strengthening is the process of increasing the load-carrying capacity of an existing structural beam. It is normally needed when:

• The building's use is changing and the new loads exceed the original design (for example, converting an office to a heavy-storage warehouse)
• Adding a mezzanine, new equipment, or an extra floor would overload the existing structure
• Cracks, corrosion, or deterioration have reduced the beam's capacity
• An engineering review has identified an original design or construction shortfall
• A new opening through a load-bearing wall transfers extra load to a beam

We use established structural strengthening methods, selected based on the consultant's design and site conditions:

• Steel plate bonding: structural steel plates epoxy-bonded and bolted to the soffit and sides of the beam to add tensile and shear capacity
• Additional steel sections: new steel beams or channels welded or bolted alongside the existing beam to share the load
• Steel jacketing: wrapping the existing beam in a fabricated steel cage, anchored back into the supports
• Concrete jacketing: enlarging the cross-section with additional reinforced concrete

The right method depends on the structural deficit, headroom available, weight constraints, and disruption tolerated during the works. We do not work with FRP (carbon fibre) strengthening systems. Where a consultant’s design calls for FRP, we coordinate with a specialist FRP contractor and integrate the steel scope around it.

Yes, always. Beam strengthening is a structural modification and must be designed by a licensed structural consultant, reviewed by Dubai Municipality, and executed by a registered contractor. For commercial or industrial buildings, Civil Defence may also need to review where the strengthening is part of a larger modification or change of use.

What we do: as a DM approved contractor for steel structure construction we manage the full permit and approval cycle, including consultant coordination, drawings, calculations, and completion certificate.

Designs follow the Dubai Building Code 2021 and the codes adopted by Administrative Resolution No. (37) of 2021:

• AISC 360 or Eurocode 3 (BS EN 1993) for the steel strengthening elements
• ACI 318 or BS EN 1992 (Eurocode 2) for concrete behaviour and design
• ASCE 7 for revised loads on the strengthened structure

For most beam strengthening jobs in Dubai, an independent third-party structural peer review is required by Dubai Municipality. Strengthening work is high-stakes by nature, so the authority wants a second engineering opinion on the design and the proposed execution method.

How we handle it: we engage approved third-party consultants on your behalf and include the coordination in our scope, or work with one you nominate. We manage review comments and revisions so the permit timeline stays on track.
