A 93m-long bridge over the White Cart Water forms the core of the Amids South transport scheme, linking an existing industrial area to Paisley town centre and Glasgow Airport. Poor ground conditions along the river corridor drove a redesign of the substructure, with foundations and pier locations adjusted to avoid weak strata and reduce settlement risk. The scheme’s experience will interest geotechnical and bridge engineers dealing with soft alluvium and variable bearing capacity on constrained urban river crossings.

Gary L. Seider, P.E., is retiring after nearly 40 years with A.B. Chance, where he was instrumental in developing helical pile and anchor systems that became core to Hubbell’s foundation solutions portfolio after its 1994 acquisition. His work helped formalise design methodologies, installation torque–capacity correlations and training standards for contractors and engineers using screw anchors in transmission, distribution and commercial foundation projects. Seider’s legacy is a mature, codified helical foundation practice that many US geotechnical and structural engineers now treat as a routine design option.

Two engineering consortia have been shortlisted by the New South Wales Government to design and deliver a fix for Mitchells Causeway on the Great Western Highway at Victoria Pass, closed since March after substantial cracking and ground movement were detected. The move follows an industry briefing and on-site inspection involving 20 Australian and international firms, signalling complex geotechnical and structural stabilisation requirements on this steep Blue Mountains section. Outcomes will directly affect detour durations, heavy vehicle access and long-term slope and pavement performance on this key freight and commuter corridor.
