About you

Skills

• Should be responsible for creating and maintaining symbol libraries, templates, and databases, configuring project settings, and troubleshooting software issues to enable seamless collaboration. Additionally, you will lead automation initiatives, integrate engineering design data with other platforms, and support digital delivery strategies for smarter, connected solutions. The candidate will also actively support project teams on proposal and project delivery tasks.
• Ideal candidates should have a Diploma/B.E/B.Tech in Civil Engineering, with 5–12 years' experience delivering multidisciplinary projects, strong knowledge of Revit/CAD functionalities, Navisworks & CDE platforms, and a passion for improving design efficiency through technology and innovation.
• Some generic requirements,
• Ability to independently produce structural drawings and BIM models with minimal supervision & maintain BIM model quality in accordance with:
• The Project Information Model (PIM)
• The approved BIM Execution Plan (BEP)
• Organisational Information Requirements (OIR), Asset Information Requirements (AIR), and ISO 19650 naming conventions.
• Ability to carry out model checks, coordination reviews, and ensure compliance with Common Data Environment (CDE) workflows.
• Ability to maintain and manage BIM model quality processes, ensuring compliance with project and organisational standards.
• Ability to share best practices and technical knowledge with the wider project team.
• Proven experience in understanding and managing coordination processes with engineers across multiple disciplines.
• Ability to attend meetings with internal and external stakeholders, including clients, and accurately prepare and maintain Minutes of Meetings (MoM).
• Ability to mentor and support graduate and junior BIM engineers, contributing to team capability development.
• Experience in coordinating CAD and BIM model inputs for multi disciplinary projects.
• Proficiency and strong working knowledge of AutoCAD.
