FSG provides specialist foundation engineering services for contractors, developers, consultants and asset owners across the infrastructure, transport, buildings, energy, resources and marine sectors.
We work on a diverse range of projects, delivering foundation solutions for buildings, bridges, transport infrastructure, wharves, marine structures, industrial facilities, renewable energy assets and other critical infrastructure.
Our team combines advanced geotechnical analysis with practical construction experience to develop foundation systems that are safe, efficient and commercially oriented. From concept and tender design through to detailed design, optimisation and construction support, we help clients select the most appropriate foundation solution for the ground conditions, loading requirements, programme constraints and project objectives. The result is foundation designs that provide value for money, manage ground related risk, enhance constructability and deliver reliable long-term performance.
Foundation Engineering Backed by Construction Experience.
Foundation engineering has been at the core of FSG’s business since the company was established. We combine a detailed understanding of the ground conditions with extensive construction experience to develop foundation and retention solutions that are practical, efficient and aligned with project objectives. By identifying risks and opportunities early, we help clients evaluate foundation options, optimise designs and improve project certainty during planning, procurement and delivery.
Our team supports projects through every stage of the foundation engineering process, from concept development and tender design through to detailed design, specification development, construction support and performance verification. We understand that successful foundation solutions must balance technical performance, constructability, programme requirements and commercial objectives, ensuring designs can be delivered safely and efficiently in the field.
FSG’s extensive industry experience, combined with one of the world's largest databases of pile testing results, provides a unique understanding of how deep foundations perform in practice. This knowledge enables us to develop more reliable and efficient designs, assess construction methodologies, optimise installation processes and provide informed advice on foundation performance. We are also recognised industry leaders in pile testing, verification and sign-off, supporting clients through foundation certification, troubleshooting, constructability reviews and the resolution of complex installation and acceptance challenges.
Design of Foundations and Ground Improvement.
FSG delivers specialist design services for foundations and ground improvement works across a wide range of ground conditions and project environments. Our approach combines advanced geotechnical analysis with extensive construction experience and real-world performance data, enabling us to develop solutions that are practical, efficient and reliable throughout their service life.
- Deep Foundations – Design of bored, CFA, driven steel and precast concrete piles and displacement piles.
- Shallow and Mixed Foundations – Design of shallow spread footings, rafts and piled rafts.
- Ground Improvement Solutions – Design and assessment of a range of systems including rigid inclusions, soil mixing, stone and sand columns, jet grouting, dynamic compaction and dynamic replacement systems to improve ground performance and optimise project outcomes.
- Advanced Engineering Analysis – Numerical modelling and geotechnical analysis supported by extensive experience in the real-life behaviour and performance of foundations, retaining structures and ground improvement systems under real construction and operating conditions.
- Performance-Based Design – Assessment of foundation capacity, settlement and serviceability using advanced engineering methodologies and insights gained from FSG’s extensive pile testing and verification database and performance monitoring of structures.
- Constructability-Focused Solutions – Design development that considers construction methodology, plant and material availability, access constraints, programme requirements and installation and verification risks.
By combining technical understanding with practical construction knowledge, FSG develops foundation and ground engineering solutions that realise value, manage risk, improve constructability and deliver dependable long-term performance.
