A levee stability example models a flood event over a confined aquifer, comparing pore-water pressure definitions under different PLAXIS licensing options (2D, LE, and LE Advanced). The case contrasts simple hydrostatic assumptions with transient seepage and confined aquifer responses, including delayed pressure dissipation and uplift at the levee toe. Results show how choice of pore-pressure model and licence level materially changes calculated factors of safety and potential slip surfaces, directly affecting design decisions for flood defence embankments on artesian foundations.

Helical piles are being positioned as an alternative to traditional drilled or spread concrete foundations for lattice and monopole communication towers, particularly where uplift, lateral loads and variable soils control design. Screw-in steel piles with helix plates can be installed with smaller rigs, generate minimal spoil, allow immediate loading and are removable at decommissioning, contrasting with large-diameter drilled shafts or pad-and-pier systems that require curing time and substantial excavation. The comparison focuses on sites with constrained access, weak or layered soils, and projects needing rapid deployment or future relocation.

Thames Water has launched procurement for a multi‑lot framework worth up to £177M (excluding VAT) to deliver site investigation surveys across its asset base. The framework will cover intrusive and non‑intrusive ground investigations, including boreholes, trial pits, in‑situ testing and laboratory analysis to support major water and wastewater infrastructure works. Geotechnical and environmental consultants and drilling contractors can expect long‑term programmes tied to pipeline renewals, treatment works upgrades and resilience schemes across the Thames Water region.
