Geotechnical and Environmental Investigations

National geotechnical and environmental consultancy

Geotechnical and environmental engineering is a fundamental component of infrastructure and building projects. At Sutcliffe, we combine our understanding of geological structures, materials and processes with advanced investigative, scientific and engineering techniques to manage ground risk, optimise design and maximise development value.

We leverage our deep understanding of geological structures, materials, and processes alongside cutting-edge investigative and engineering techniques to manage ground risk, optimise designs, and maximise development value.

Our specialised services include:

• Geotechnical subsurface investigations – We assess soil conditions, rock mechanics, and groundwater conditions to inform foundational design and construction strategies
• Foundation design and review – Design and review services for both shallow and deep foundations, ensuring stability and safety in all types of structures
• Testing and supervision – Rigorous testing and on site supervision to guarantee the highest quality of work and adherence to relevant standards

Our geotechnical teams collaborate with planners, toxicologists, and structural and civil engineers, and play a vital role from early planning stages through to construction, as well as the inspection and rehabilitation of existing facilities. With a proven track record of designing and implementing effective site investigations across the UK, we mitigate financial risks and provide practical solutions for highways, foundations and drainage designs. This ensures that our detailed designs consider environmental constraints and effectively address any complications.

Our expertise extends to a wide variety of geotechnical and environment challenges, including:

• Building foundations
• Tunnels, caverns and shafts
• Earth retaining structures
• Ground improvement and stabilisation
• Slopes and landslides
• Deep excavations and pavements
• Groundwater modelling and dewatering
• Forensic investigations

Each investigation is tailored to the site’s specific geographical, geological, hydrogeological and environmental context. We offer comprehensive services including desk-based studies, contaminated land assessments, geotechnical appraisals and the development of cost-effective remediation strategies. Our team also supervises and verifies ground preparatory and remediation works to ensure successful project outcomes.

Regulatory compliance and standards

We ensure all our work adheres to the highest standards and guidelines, including:

• CLR11 Model Procedures for the Management of Land Contamination
• BS10175:2011+A2:2017 Code of Practice for Site Investigations
• BS 5930:2015 Code of Practice for Site Investigations
• BS EN ISO 22475-1:2006 Geotechnical Investigation and Testing

As a proud member of the Association of Geotechnical & Geo-environmental Specialists (AGS), our recognised practitioners are equipped to cover both geotechnical and geo-environmental specialisms.
