Halcrow’s Maritime Innovation Became a BSI Standard 📌 The Jeddah-type Quay Wall is a unique hollow block wall system developed by Halcrow in the early 1960s, specifically designed to address the soft geotechnical conditions of King Faisal Port in Jeddah, KSA. At that time, Halcrow made significant investments in research, development, and employee training, leading to groundbreaking advancements in port infrastructure and coastal protection. Unlike many modern-day consultancy firms, Halcrow's approach prioritized technical expertise and engineering innovation, shaping the industry through its pioneering solutions. The Jeddah-type blockwork quay wall consists of large precast hollow concrete blocks, strategically stacked to form a gravity-based structure. The voids within the blocks were filled with crushed rocks/concrete/sand, enhancing stability and loading for appropriate pressure distribution to underlying seabed. The structure relies solely on its self-weight for stability, eliminating the need for anchors or piles. An in-situ concrete capping beam was added to provide structural continuity, support operational loads, and accommodate service trenches for utilities. The Jeddah Wall construction method was later acknowledged by the British Standards Institution (BSI) as a standard gravity wall type and has been officially referenced in British Standards (BS6349 Part 2), solidifying its status as an industry benchmark. The construction of this innovative structure was successfully executed by the world-renowned contracting company, Archirodon Group N.V. further demonstrating the engineering excellence and significance of the project. Halcrow was once a trusted leader in engineering and maritime consultancy, with a legacy spanning over 75 years in the Middle East. During the 1990s, its Middle East office was regarded as a center of excellence, led by engineering visionaries. The firm’s Chairman, a renowned coastal engineering expert with a doctorate, ensured a strong focus on innovation and excellence. Over time, Halcrow’s presence faded as corporate priorities shifted away from its core technical strengths. The increasing influence of finance and HR personnel over engineering leadership led to misguided decisions, including the belief that engineering innovation could be outsourced to low-cost regions. This weakened the firm’s technical foundation and ultimately led to firms’ acquisition and decline in the engineering world. Despite its decline, Halcrow’s engineering legacy endures through its pioneering projects, which continue to serve as benchmarks in port development and maritime engineering in the Middle East and beyond. The Jeddah Wall remains a testament to Halcrow’s innovative approach, demonstrating how cutting-edge design solutions can overcome challenging geotechnical conditions and shape the future of port infrastructure.
