Job description

Job Description

We are seeking a skilled and detail-oriented Tunnel Lining Design Engineer to join our team. The successful candidate will be responsible for the design, analysis, and optimization of tunnel lining systems for a variety of underground infrastructure projects. This role requires expertise in structural and geotechnical engineering, advanced modeling techniques, and a deep understanding of tunneling methods and materials.

Key Responsibilities

• Tunnel Lining Design
• Develop detailed designs for tunnel linings, including segmental linings, shotcrete linings, and cast-in-place concrete linings.
• Perform structural analysis to ensure the tunnel lining can withstand geotechnical loads, hydrostatic pressures, and operational stresses.
• Optimize lining designs to achieve cost efficiency, durability, and compliance with project specifications and safety standards.
• Geotechnical and Structural Analysis
• Collaborate with geotechnical engineers to assess ground conditions and their impact on tunnel lining design.
• Conduct numerical modeling and finite element analysis (FEA) to simulate soil-structure interaction and assess the performance of lining systems.
• Evaluate the effects of seismic loads, groundwater pressure, and other external forces on tunnel linings.
• Material Selection and Specification
• Select appropriate materials for tunnel linings, considering factors such as durability, load‑bearing capacity, and environmental conditions.
• Specify reinforcement requirements, waterproofing systems, and joint details for tunnel linings.
• Project Coordination
• Work closely with multidisciplinary teams, including geotechnical engineers, structural engineers, and contractors, to ensure seamless integration of tunnel lining designs.
• Participate in design reviews, workshops, and client meetings to present design concepts and address technical queries.
• Construction Support
• Provide technical guidance during the construction phase, including reviewing shop drawings, resolving design‑related issues, and ensuring compliance with design specifications.
• Monitor the performance of tunnel linings during construction and recommend adjustments as needed.
• Quality Assurance and Compliance
• Ensure that all designs meet relevant codes, standards, and project requirements (e.g., Eurocodes, BS, ASTM, AASHTO, ITA guidelines).
• Conduct quality checks and peer reviews of design deliverables to maintain high standards of accuracy and reliability.
• Innovation and Research
• Stay updated on the latest advancements in tunnel lining materials, methods, and technologies.
• Develop and implement innovative solutions to improve the performance and efficiency of tunnel lining systems.

Qualifications

Education

• Bachelor’s degree in Civil Engineering, Structural Engineering, or a related field. A Master’s degree in Structural or Geotechnical Engineering is preferred.

Experience

• 2 years of experience in tunnel design, with a focus on tunnel lining systems.
• Proven experience in designing linings for various tunneling methods, including:
• Tunnel Boring Machine (TBM) segmental linings.
• New Austrian Tunneling Method (NATM) shotcrete linings.
• Cut-and-cover tunnel linings.

Technical Skills

• Proficiency in structural and geotechnical analysis software such as PLAXIS, MIDAS GTS, Abaqus, SAP2000, or similar tools.
• Strong understanding of soil‑structure interaction, rock mechanics, and hydrogeological considerations.
• Experience with finite element modeling (FEM) for tunnel lining behavior under various loading conditions.
• Knowledge of waterproofing systems, joint design, and durability considerations for tunnel linings.

Certifications

• Professional Engineer (PE), Chartered Engineer (CEng), or equivalent certification is highly desirable.
• Membership in professional organizations such as ITA (International Tunneling Association) or ASCE is a plus.

Soft Skills

• Strong analytical and problem‑solving skills.
• Excellent communication and technical writing abilities.
• Ability to work collaboratively in multidisciplinary teams.
