Settlement prediction in layered soils is shown to depend strongly on how vertical stress increments are computed, comparing classical Boussinesq-based methods with numerical analyses in Settle3, RS2, and RS3. The piece contrasts 1D influence-factor approaches against 2D/3D finite element and finite difference models that capture stiffness contrasts, non-linear behaviour, and complex load geometries. For practitioners, it signals when simple elastic solutions become overly conservative and when full numerical stress redistribution is needed to refine serviceability settlement estimates.

Quaise Energy is advancing Project Obsidian in Oregon, aiming to build the first superhot geothermal plant by drilling into rock above 300°C and delivering a baseload 50 MW from only a handful of wells by 2030. A modelling analysis presented at the 2026 Stanford Geothermal Workshop by senior mechanical engineer Daniel W. Dichter indicates higher subsurface temperatures could ultimately support 250 MW in phase two, with a regional goal of 1 GW. The confirmation well is due online later this year, with lab work at Oregon State University recreating extreme downhole geochemical conditions.

Keller has appointed Scott Nichols as President of Keller North America and promoted Curtis Cook to President of its US Foundations business unit, reshaping leadership at one of the region’s largest geotechnical contractors. Nichols will oversee a portfolio spanning ground improvement, grouting, deep foundations and earth retention across Canada, the United States and Mexico, while Cook will focus on US piling and shoring operations. The changes signal continuity of in-house leadership and may influence procurement, partnering and design–build delivery on major foundation and ground engineering projects.
