Senior Manager: Technical Geotech

Overview

1. Client Representation & Governance

• Act as the primary focal point for all geotechnical and ground engineering matters across the transportation/rail program.
• Represent the client in technical, design, and risk workshops with consultants, contractors, independent reviewers, and authorities.
• Interpret and communicate client requirements, design criteria, and geotechnical standards; ensure they are embedded in all relevant contracts and deliverables.
• Provide independent, objective advice and recommendations to client leadership on geotechnical issues, risks, and impacts on scope, time, cost, and safety.

2. Ground Investigation Strategy & Management

• Lead development and review of project wide ground investigation strategies tailored to rail and transportation infrastructure.
• Review scopes for site investigations, including borehole locations, in situ testing, sampling, laboratory testing, and monitoring requirements.
• Oversee execution and reporting of investigations by consultants and contractors; ensure data quality, coverage, and relevance to design and risk assessment.
• Maintain an up to date understanding and documentation of baseline ground conditions, uncertainties, and allowances for unforeseen conditions.

3. Geotechnical Design Management & Technical Assurance

• Manage and oversee geotechnical design across all stages for assets such as:
• Rail embankments, cuttings, formation and subgrade
• Foundations for bridges, viaducts, stations, depots, masts, and noise barriers
• Tunnels, shafts, cut and cover structures, deep excavations, retaining walls
• Ground improvement works, slope stabilization, and ground structure interaction
• Review and challenge geotechnical design reports, analyses, models, calculations, and drawings for compliance with:
• Employer s requirements and project design criteria
• Local codes, rail requirements, and authority regulations
• Relevant international standards
• Chair or participate in geotechnical design reviews, peer reviews, and value engineering workshops, promoting safe, robust, and cost effective solutions.
• Ensure requirements management and traceability for geotechnical and earthworks requirements from capture through verification and close out.
• Oversee implementation of technical assurance processes for geotechnical deliverables, including independent checkers and verification activities.
• 4.
• Interfaces with Civil, Structural, Track & Systems
• Coordinate geotechnical interfaces with:
• Civil and structural design (foundations, abutments, retaining structures, tunnels)
• Track design (alignment, formation level, trackbed design, track ground interaction, settlement criteria)
• Stations, depots, buildings, and ancillary structures
• Drainage, utilities, highways, and adjacent developments
• Maintain and manage interface registers for geotechnical related issues, ensuring early identification and resolution.
• Support integrated multi discipline coordination to ensure that geotechnical constraints and risks are fully accounted for in broader engineering decisions.
• 5.
• Safety, Risk & Engineering Assurance (Non Operational)
• Embed safety by design principles in all geotechnical solutions, covering both temporary (construction) and permanent conditions.
• Review and monitor geotechnical contributions to RAMS, hazard identification, risk assessments, and mitigation measures (slope instability, settlement, groundwater, seismic effects, ground collapse).
• Coordinate with safety, risk, and assurance teams, as well as independent safety assessors (ISA) where geotechnical risks influence railway safety or regulatory approvals.
• Ensure geotechnical risks are captured in project risk registers with clear ownership, mitigation plans, and monitoring strategies.

6. Construction Support & Design Build Coordination

• From a PMC perspective, oversee how geotechnical designs are translated into construction methodologies and sequencing; identify constructability issues early.
• Review and comment on contractors temporary works designs, excavation support, dewatering, and ground improvement methods with respect to safety, ground movements, and impact on third party assets.
• Support the client in assessing and agreeing geotechnical design changes, technical deviations, and value engineering proposals.
• Provide senior geotechnical input on RFIs, non conformance reports, and unexpected ground conditions; drive timely and safe resolutions that protect client interests.
• Monitor performance of critical geotechnical works through review of monitoring data (e.g., settlement markers, inclinometers, piezometers) and contractors reports.
