Expert in the design, construction & forensic analysis of defects & failures in geotechnical works including: • Deep basements • Deep foundations • Bored piles • Secant piles • Diaphragm walls • Continuous flight auger piles • Barrettes • Rock anchors

Grant has acted as Expert Witness on projects requiring rigour and expertise in contaminated land, geotechnical engineering and hydrogeology. He has 35 years’ post-graduate experience in engineering geology, geotechnical engineering, contaminated land, hydrogeology and remediation. He has an excellent reputation within his field which stems from his innate ability to effectively communicate, orally and in writing, technically complex matters in terms that his audience understands.
