Major Project Milestone Achieved in Guildford

We're thrilled to announce that we have wrapped up the crucial shaft sinking and Microtunnelling works at the Guildford Sewage Treatment Works (STW) Scheme for our client BAM UK & Ireland.

Our team has expertly installed 6 segmental shafts with diameters ranging from 5m to 12.5m and completed a total of 1375m of 1500mm diameter tunnelling. Among these, the standout is a 334m section complete with a 350m radius horizontal curve. Our dedicated team is now directing their expertise towards the final stages, a 1500mm diameter hand drive and meticulous shaft finishing works. Huge thanks go to all involved.
