Senior specialist support from understanding the ground through design, peer review, construction and performance. Geotechnics Plus focuses on technically demanding work where ground behaviour, uncertainty or project consequence requires experienced judgement.
Our services are structured around four areas: advisory and assurance, ground understanding and advanced analysis, ground engineering, and construction performance. Engagements can be focused on one critical issue or support a project through multiple stages.
Objective technical judgement for decisions, reviews, pursuits and project strategy.
Senior technical input on assumptions, design basis, analyses, technical risk and high-consequence project decisions.
Typical support: peer review, design assurance, technical strategy, second opinions, technical workshops, forensic review and due diligence.
Specialist ground-risk input before major design, commercial or delivery commitments are made.
Typical support: design-build pursuits, bid strategy, alternatives, constructability, value engineering, site due diligence and early foundation strategy.
Build the right ground model, then apply the level of analysis needed to resolve the technical question.
Planning and interpretation of geotechnical investigations to establish a defensible understanding of site conditions and design parameters.
Typical support: borehole/CPT/laboratory program planning, existing-data review, investigation oversight, ground models, parameter selection and targeted supplementary investigation.
2D and 3D finite-element analysis for complex ground behaviour, soil–structure interaction, staged construction, deformation and stability.
Typical support: model development, calibration, sensitivity studies, consolidation, settlement, load–deformation assessment and interpretation.
Assessment of seismic ground response, liquefaction, cyclic behaviour and deformation demand for ground-sensitive infrastructure and facilities.
Typical support: ground response, liquefaction, post-liquefaction behaviour, cyclic response, seismic deformation and dynamic soil–foundation interaction.
Design, analysis and review of the ground systems that control stability, deformation and constructability.
Strategy, analysis and technical review for foundations, retaining systems, deep excavations, soft ground and ground-improvement solutions.
Typical support: shallow and deep foundations, piles, piled rafts, shoring, excavation support, settlement, underpinning and ground improvement.
Geotechnical assessment of earth structures and mine-related ground systems where stability, seepage, consolidation and staged loading govern performance.
Typical support: embankments, fills, slopes, soft-ground construction, tailings-related assessment, seepage/stability interaction, consolidation and staged construction.
Use observed behaviour and construction realities to manage ground risk during delivery.
Focused technical support when actual ground conditions, construction sequencing or observed performance creates risk or requires a timely engineering decision.
Typical support: unexpected ground conditions, constructability, instrumentation strategy, trigger/action frameworks, movement interpretation, observational-method support, mitigation and recovery strategy.
The scope can be narrow and targeted or continue through a longer project phase. The engagement model should match the technical risk and the decision that needs to be made.
A focused analysis, review, technical memorandum or design input with a clear question, scope and deliverable.
Objective assessment of a critical design, assumption, risk or proposed solution before an important decision is made.
Flexible senior specialist capacity through pursuits, design development, construction or periods of elevated technical risk.
Geotechnics Plus can work directly with owners and contractors or alongside engineering and multidisciplinary project teams.
