Coordination challenges are inherent when modifying existing buildings, particularly due to unforeseen conditions that may not be captured during preliminary surveys or site inspections. These include previously installed elements or undocumented structural components that can interfere with planned works. To address this, the structural design was approached modularly. This allowed for flexibility in adapting to site conditions, enabling quick adjustments to avoid clashes without compromising the overall design intent. The modular strategy ensured that changes could be implemented efficiently, with minimal disruption to the construction sequence. As the site was fully operational throughout the construction period, numerous constraints had to be carefully managed. The movement of goods via forklifts and trucks posed safety risks to both construction personnel. Additionally, the installation and modification of structural elements within the warehouse introduced potential hazards to employees during active operations. Effective management of these risks required active collaboration among all stakeholders, including the client, consultants, and the contractor. Extensive consultations were conducted to identify areas requiring modification and assess their impact on logistics and workflow. This ensured that construction activities were planned and executed with minimal interference to ongoing operations. Minimising disruption to daily activities was a top priority. Creative solutions were developed to enable structural modifications while maintaining operational continuity.
