Event Expired

This webinar has taken place


23rd Jul 2021 12:00


1hr 30mins

The UK is committed to achieving net zero carbon emissions by 2050. But how do you achieve this on a geotechnical construction site?

This webinar, the second in the Federation of Piling Specialists Sustainability Series, sees four expert speakers from the special foundations industry discuss the key drivers for decarbonisation, showcase successful case studies and investigate the different technologies and materials available on the market.

This webinar also discusses:

  • What is perceived as low carbon?
  • What technologies exist for the piling industry to use?
  • How can the piling industry work to develop low carbon technologies?
  • The sustainable and economic benefits of Cemfree concrete

Presenters for the seminar include Heleni Pantelidou, Associate Director at Arup, Stuart Norman, Managing Director at Keltbray (Piling), Andrew Mullholland, Consultant at AMCRETE and Andrew Waghorn, Operations Director at Murphy Ground Engineering.


Decarbonisation Transition: A Consultant’s Perspective

Heleni Pantelidou, Associate Director at Arup

Heleni provides a short overview of the trends around decarbonisation from policy, clients and projects, describing the issues consultants are grappling with but also the opportunities we can work on together.

What is Low Carbon Concrete?

Presented by Andrew Mullholland, Consultant at AMCRETE UK Ltd.

Andrew’s presentation unpacks what is perceived as low carbon, the different technologies that are available, how to navigate through the standards and what opportunities exist for the piling industry to use and participate in developing low carbon technologies

Cemfree: Low Carbon Concrete for Piling and the Low Carbon Concrete Within Aggressive Ground (LOCOWAG) project

Presented by Andrew Waghorn, Operations Director at Murphy Ground Engineering

Andrew’s presentation demonstrates the sustainable and economic benefits of Cemfree concrete in conjunction with confirming its engineering performance in live ground engineering works during the LOCOWAG project. Andrew encourages other ground engineering companies, especially those within the FPS, to consider and implement more sustainable materials via the sharing of best practice. Andrew is also keen to support the wider adoption of Cemfree concrete in multiple applications within the construction industry and through key J. Murphy and Sons Ltd. infrastructure and civil engineering projects.

Earth Friendly Concrete – Permanent Works Use for piled foundations

Presented by Stuart Norman, Managing Director (Piling), Keltbray & FPS Environmental Sustainability WG Chair

Stuart’s presentation sets out the Engineering process adopted ahead of the first ever use of an AACM for permanent works within piled foundations at the Canada Water project.

It focuses on the route through the codes adopted together with frequently asked questions encountered by clients and Engineers alike relating to the use of Earth Friendly Concrete (EFC).

Insight is given into the costs, value and embodied carbon savings made for this UK first so that others may swiftly follow.
