Free TDI Training Webinar – WJ Group (Hydrogeological Investigations for Construction Works)
Hydrogeological investigations are typically undertaken to supplement geotechnical investigations for construction projects where impacts from groundwater are anticipated. The investigation strategy may involve groundwater level monitoring to identify short or longer-term fluctuations or trends and permeability assessment by variable head testing and packer testing. The short comings of these established tests will be briefly considered and contrasted with pumping tests which are often the main element of a hydrogeological investigation. Valuable information can be obtained where the pumping test design and specification aligns with the project scope. Where this is not the case the data obtained can be of minimal use.
The presentation will draw on material from the forth coming Geological Society Publication Engineering Geology of Groundwater in Design and Construction: Chapter 6. Observational Models: Quantifying the Conceptual Model through Investigation co-authored by the presenters together with Mark Lee (Atkins).
This session will be presented by Toby Roberts, Chairman of WJ Groundwater Limited and William Powrie, Professor of Geotechnical Engineering at the University of Southampton.
Toby Roberts is an expert in the design and implementation of groundwater control systems for large excavations, foundations and tunnels with extensive contract experience in Europe, the Middle East and Canada. Toby is a founder member and current Chairman of the international dewatering contractor WJ Groundwater. He has authored/co-authored more than 40 publications on construction dewatering including CIRIA C750 (2016) the UK best practice guide for construction dewatering. Toby Roberts is a Fellow of the Royal Academy of Engineers, a Chartered Civil Engineer and Chartered Geologist.
William Powrie is an expert in geotechnics with particular interest in transport infrastructure and sustainable waste and resource management. He is currently working with HS2 on geotechnical earthworks and has authored a textbook on Geotechnical Engineering and co-authored CIRIA reports C750 (2016) best practice guide for construction dewatering, and C760 (2017) embedded retaining wall design. William Powrie is a Fellow of the Royal Academy of Engineers and a Chartered Civil Engineer.
