The Tekla 3D RC Modeller / Draftsman is responsible for developing high-quality 3D reinforced concrete models using Tekla Structures for the most complex buildings of the EPR Nuclear Island on Sizewell C. The role focuses on detailed RC modelling and detailing, within a BIM-managed environment, working in close coordination with Senior Draftsmen and the BIM Coordinator. The position supports the delivery of safety-critical, highly congested reinforced concrete structures in a regulated nuclear context.
Job Responsibility:
Develop and maintain 3D reinforced concrete models using Tekla Structures
Model complex RC elements including: Rafts, basemats, thick walls and slabs, Dense reinforcement layouts, Openings, penetrations, embedments, and construction joints
Produce RC detailing outputs including: General Arrangement (GA) drawings, Reinforcement drawings, Bar bending schedules (BBS)
Implement engineering mark-ups, sketches, and comments accurately into the 3D model
Work within a BIM-managed environment, following the project BIM Execution Plan (BEP)
Coordinate closely with: Senior Draftsman / Lead RC Detailer for technical guidance, BIM Coordinator for model federation, clash management, and data exchange
Ensure Tekla models are consistent with: Naming conventions, Model structure, Level of detail and information required at each design stage
Support resolution of clashes and interface issues identified during coordination reviews
Deliver modelling outputs in compliance with: Project procedures and nuclear quality requirements, Applicable design codes (Eurocodes, RCC-CW where applicable)
Apply a strong nuclear safety culture to modelling activities
Manage revisions and updates in line with document and model control procedures
Support responses to design review comments and construction queries related to RC detailing
Requirements:
Proven experience in 3D reinforced concrete modelling using Tekla Structures
Strong understanding of RC detailing principles and constructability
Ability to interpret structural drawings, calculations, and engineering intent
Experience working in large infrastructure or complex building projects
High level of accuracy, attention to detail, and ability to work to strict quality standards
Ability to work effectively within a structured, multidisciplinary team
You must have the right to work in the UK
Nice to have:
Experience on nuclear or other regulated projects
Exposure to EPR, HPC, or SZC-type structures
Familiarity with BIM workflows and Common Data Environments (e.g. ProjectWise)
Experience working with dense reinforcement and safety-critical RC structures
