West F5 Building – Dubai
Project Overview
CDE Engineering Services was appointed by Waterseal to carry out condition assessment, and develop repair and strengthening design solutions for the West F5 Building, a 19-storey tower located in Business Bay, Dubai.
The structure had been partially constructed by a previous developer up to podium level and remained on hold for several years before being acquired for continuation. The project aimed to evaluate the condition of existing structural elements and develop strengthening solutions to accommodate new architectural modifications and loading requirements.

Location
Dubai, UAE
Client Challenge
The building had been exposed to environmental conditions for an extended period, leading to deterioration of structural elements.
Basement levels had experienced flooding, resulting in chloride ingress and corrosion of reinforcement. Visible defects included delamination, spalling, and cracking in slab soffits and exposed elements.
Additionally, proposed architectural modifications introduced increased loading demands, requiring reassessment and strengthening of structural components.
Scope of Work
Our Approach
CDE carried out a detailed investigation combining field testing and structural analysis.
Visual inspection and testing were conducted to assess deterioration and material properties. The assessment included evaluation of chloride contamination, corrosion potential, and extent of damage.
Analytical evaluation was performed to assess the structural capacity of elements under revised loading conditions, ensuring compliance with strength and serviceability requirements.
Key Findings
Basement levels showed significant signs of deterioration due to flooding and water ingress. Chloride contamination was identified as the primary cause of corrosion of reinforcement.
Delamination and spalling were observed in slab soffits, particularly around cracks and openings. Chloride profiles and testing confirmed that contamination levels were sufficient to initiate and sustain corrosion.
The structural elements were found to be affected by durability-related issues, requiring both repair and strengthening interventions to ensure long-term performance.
Solutions & Recommendations
CDE proposed a comprehensive rehabilitation strategy addressing both structural and durability concerns.
Repair of delaminated concrete was recommended, along with reinstatement of waterproofing systems at construction joints, cracks, and other water ingress points using appropriate injection techniques.
To mitigate corrosion risks, an impressed current cathodic protection (ICCP) system was recommended for long-term protection of basement elements.
Strengthening measures including concrete enlargement and CFRP systems were proposed to enhance structural capacity and meet design requirements.
These measures were designed to restore structural integrity, prevent further deterioration, and extend service life.
Outcome
The project provided the client with a clear understanding of structural condition and deterioration mechanisms.
Through targeted repair and strengthening design, CDE enabled safe continuation of construction while addressing durability risks and structural deficiencies. The recommended solutions ensure improved performance, durability, and long-term reliability of the building.
