The Gulf Cooperation Council (GCC) countries — the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman — experience some of the most extreme climatic conditions on earth. Summer temperatures routinely exceed 45°C, humidity levels in coastal cities can reach 90% or more, and sand-laden winds are a constant environmental factor. These conditions place extraordinary demands on building materials, construction methods, and long-term asset performance.
It is no surprise, then, that building defects in the GCC often have a distinctly different character to those encountered in more temperate climates. While construction defects are a global phenomenon, the types, causes, and severity of defects in the Middle East are heavily influenced by the region's harsh environment. Understanding these unique challenges is essential for developers, contractors, consultants, and legal professionals involved in construction disputes.
Waterproofing failures are among the most common and costly defects in the region. Despite the arid climate, the GCC experiences intense — if infrequent — rainfall events, and many buildings are designed with inadequate waterproofing systems. Flat roofs, podium decks, and below-grade structures are particularly vulnerable. When waterproofing membranes fail, the resulting water ingress can cause significant damage to finishes, MEP systems, and structural elements, leading to expensive remediation and protracted disputes over liability.
Façade defects are another major category. The GCC's skyline is defined by its iconic curtain wall and unitised façade systems, many of which must perform under extreme thermal cycling — from scorching daytime temperatures to air-conditioned interiors just centimetres away. This thermal stress can cause sealant failures, glass breakage, panel distortion, and air leakage. Salt-laden coastal air adds a further corrosion risk, particularly for aluminium and steel components.
Concrete durability is a significant concern across the region. The combination of high temperatures, chloride-rich soils and groundwater, and the use of locally sourced aggregates — which may contain deleterious materials — can accelerate carbonation and chloride-induced corrosion of reinforcement. Cracking, spalling, and structural deterioration can occur far earlier than the design life would suggest, particularly where quality control during construction was inadequate.
MEP (mechanical, electrical, and plumbing) systems in the GCC must work harder than almost anywhere else in the world. Air conditioning systems operate at near-maximum capacity for months on end, and failures in HVAC design, installation, or commissioning can result in inadequate cooling, excessive energy consumption, and condensation problems that damage interiors and promote mould growth. Plumbing systems are also subject to thermal expansion issues and, in some areas, aggressive water chemistry.
The rapid pace of development in the region has, at times, contributed to defects through compressed construction programmes, an over-reliance on the lowest-cost supply chain, and insufficient quality assurance and quality control (QA/QC) processes. While the industry has matured significantly in recent years, the legacy of earlier construction booms continues to generate disputes as buildings age and defects manifest.
Investigating building defects in the GCC requires a specialist approach. A construction expert must understand not only general building pathology principles but also the specific environmental, material, and regulatory context of the region. This includes familiarity with local building codes (such as the Abu Dhabi International Building Code and Dubai Municipality regulations), international standards (such as BS, ASTM, and EN standards), and the particular challenges of construction in extreme heat.
At Construction Expert Witness, our building pathology experts have investigated defects on projects ranging from luxury residential towers and five-star hotels to commercial offices and industrial facilities across the UAE and the wider GCC. We combine technical rigour with practical experience to identify the root cause of defects, assess the extent of damage, and recommend proportionate remediation strategies.
Our reports are prepared to a standard suitable for use in arbitration, litigation, and adjudication proceedings, and our experts are experienced in providing oral testimony before tribunals across the region. Whether the issue is a leaking podium deck in Dubai, a deteriorating façade in Doha, or concrete corrosion on a coastal development in Abu Dhabi, we provide the expert insight needed to resolve the dispute fairly and efficiently.
