Imperial College emeritus professor John Burland has called on the land-based piling sector to undertake a programme of research comparable to that delivered by the offshore business in recent years.
Speaking at Chalk 2018 conference yesterday, Burland made the comment urging the land-based industry to deliver similar savings in his conference closing speech.
Earlier during the second day of the conference, Imperial College professor of geomechanics Richard Jardine had outlined the benefits delivered for monopiles driven in sand and clay through the Pile Soil Analysis (Pisa) project. “The results have helped to cut costs through improved design,” he said.
Jardine went on to detail work on the axial-lateral pile analysis for Chalk (Alpaca) project that is aiming to deliver similar benefits for offshore monopiles driven in Chalk. He said that this project had the potential for the industry to save millions in terms of improved design and reduce installation costs and called on the industry to share good quality site investigation data to support the Alpaca project.
Burland referred to this work and said: “If the land-based industry was to mount a similar programme of work for bored piles, there could be very significant savings indeed. There is a lot of understanding still to be developed with regards to pile shaft resistance.”
