**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.
