Dr Mothersille visits Design Consultants ARCADIS in Birmingham, UK – Jan 2019

Design consultants ARCADIS have secured significant amounts of geotechnical design work related to the HS2 project and as part of an ongoing initiative to improve the knowledge and awareness of their design team, they invited Dr Mothersille to deliver a lunchtime presentation on SBMA technology. ARCADIS anticipate that multistage anchor technology could prove useful on forthcoming HS2 contracts where large retaining structures are proposed in cohesive soils.

The presentation lasted approximately 1 hour and a short Q & A session was allowed for at the end. The feedback was very positive and certainly indicated that considerable benefits were derived for those engineers that attended.
