Matthew Penfold

Principal Geotechnical Engineer

With a masters degree in Engineering Geology from Imperial College and some 15 years’ experience in geotechnical and geoenvironmental investigation and consultancy, Matthew has been involved with numerous ground investigations for a wide variety of developments in a range of geological conditions. In 2012, he obtained chartered status from the Geological Society of London, reflecting his level of experience and understanding of geological materials and is currently working towards obtaining CEng status. Matthew is also a member of the newly established AGS Geotechnical Working Group.

He has gained particular experience in carrying out complex combined geotechnical and geoenvironmental investigations on former industrial sites in the Southeast of England, including a former chemical works in Dagenham, an industrial laundry site in Catford and more recently a large-scale redevelopment of the Royal Albert Dock in east London. He also has experience of self-boring pressuremeter testing to measure the in-situ stiffness and strength of the London Clay and is familiar with CPT investigations both for strength data and clearance of unexploded ordnance, most recently the use of low-headroom equipment to complete combined CPT and pressuremeter testing within a basement car park.  Matthew has completed numerous specialist geotechnical analyses, including analysis of an unstable slope on an historical landslip in Hythe, Kent and an analysis of the effects of disused military tunnels on a new development in Chatham.

Matthew recently completed a four-month placement with the design team of Cementation Skanska Ltd, where he gained valuable experience in the design and analysis of piled foundations and piled retaining walls. He is a member of our Ground Movement Assessment Group and his work has also included a number of detailed ground movement analyses, including the prediction of the likely settlement of a pile group supporting a high-rise structure near Elephant and Castle and more recently for a number of deep basement constructions in central and west London
