BIM - A UK Foundation Sub-Contractors Perspective-Paper

Paper

Pdf Summary

The paper reviews Building Information Modelling (BIM)—understood broadly as the creation, sharing and management of digital project data—from the perspective of UK foundation subcontractors. It argues that BIM is not dependent on 3D models: its value lies in reliable information workflows throughout a project’s life cycle, including records that may support future site reuse or development.<br /><br />UK foundation contractors can generally meet BS 1192 requirements, and major contractors commonly use BIM execution plans aligned with PAS 1192-2. However, foundation subcontractors are often not contractually required to follow project digital-data protocols, contributing to slow and inconsistent adoption. Although standards and technologies exist, information is not always transferred effectively: for example, AGS site-investigation data is widely available but is not routinely used by foundation contractors.<br /><br />Progress includes FPS guidance on workflows, data classification and software; 3D and 4D modelling for ground conditions, design, logistics and construction planning; and digital field records using tablets and cloud systems. Laser scanning and drones also improve measurement, inspection, productivity and safety. Emerging opportunities include virtual and mixed reality for training and safety planning, linking design changes to programme and cost impacts, and connecting equipment instrumentation directly to as-built records.<br /><br />The paper identifies stronger collaboration as essential, while noting concerns around copyright and liability. It recommends consistent compliance with BS 1192, documenting measurable commercial benefits, and—most importantly—making digital-data requirements contractual at project level. Wider adoption of standardised workflows and data formats would help the foundation sector catch up with the broader construction industry.
