Future Evening Meetings

The BTS holds monthly evening meetings from September to June, generally on the third Thursday of the month. Unless otherwise stated, the meetings are at the Institution of Civil Engineers (ICE) with the lecture starting at 6pm. Additional meetings are arranged by the BTS Young Members, by regional groups and as joint meetings with other societies.

Cadent Gas Chelsea to Battersea Pipeline Tunnel Project

This presentation will focus on the design and construction of the Chelsea to Battersea gas pipeline tunnel project. The project included construction of a 30m deep and 330m long pipe jack tunnel, crossing the River Thames between Chelsea Embankment and Battersea Park. The challenges during design, site set up and construction including complex interfaces with third parties such as RHS Chelsea Flower Show will be discussed. Close collaboration between all parties was necessary to ensure safe completion of the works including safe construction of a 30m deep shaft within a constraint space in Battersea Park. A robust programme of instrumentation and monitoring was carried out during the construction works to record and monitor the ground behaviour and to ensure minimum impact on the existing third party assets.

Joint BGA/BTS meeting. Booking Required. The Skempton Award Lecture: Water and Tunnelling – lessons from 40 years of interesting problems.

The talk will highlight David Hartwell's experience in finding solutions to problems with groundwater associated with shafts and tunnels over the last 40 years. Along the way lessons were learnt, many of which do not appear in groundwater or soil mechanics text books. Two major projects will be highlighted: the Storebaelt tunnels in Denmark, including pressure relief for the cross passages and the MOSES offshore dewatering scheme. The second major project concerns the recovery of the flooded Docklands Light Rail tunnel under the river Thames; freezing was considered but the scheme adopted included wells in the river and horizontal wells drilled from within the tunnel. David was awarded the 13th Skempton medal by the BGA in 2018. He is recognised world-wide as a leading authority on groundwater and tunnelling and has extensive experience investigating and developing practical solutions to groundwater related geotechnical issues for tunnels, heavy civil engineering and mining projects.
