Senior Draftsman 3D
Job Description
The Senior Draftsman – Tekla 3D RC Modeller is responsible for delivering high-quality 3D reinforced concrete models and detailing using Tekla Structures for the most complex buildings of the EPR Nuclear Island on Sizewell C.
The role is primarily production-focused, with strong technical autonomy on RC modelling, working in close coordination with the Chief Draftsman and the BIM Coordinator within a BIM-managed and regulated nuclear environment.
Scope of Works – Nuclear Island Buildings
The role will primarily support modelling activities for Nuclear Island structures, including:
Reactor Buildings and Common Raft
Fuel Buildings
Safeguard Buildings
Airplane Crash-resistant Buildings
These structures involve very thick RC sections, high reinforcement densities, complex embedments, and stringent constructability constraints.
Key Responsibilities
3D RC Modelling & Detailing (Tekla)
Develop and maintain 3D reinforced concrete models using Tekla Structures.
Model complex RC elements, including:Common rafts, basemats, thick walls and slabs
Highly congested reinforcement layouts
Openings, penetrations, embedments, and construction joints
Produce RC detailing deliverables:General Arrangement (GA) drawings
Reinforcement drawings
Bar Bending Schedules (BBS)
Accurately implement engineering sketches, mark-ups, and design comments into the Tekla model.
BIM Environment & Coordination
Work within a BIM-managed environment in accordance with the project BIM Execution Plan (BEP).
Coordinate closely with:Chief Draftsman / Lead RC Detailer for technical direction and prioritisation
BIM Coordinator for model federation, clash management, and exchanges
Ensure Tekla models comply with:Model structure and naming conventions
Required Level of Detail (LOD) and Level of Information (LOI)
Support the resolution of clashes and interface issues identified during coordination reviews.
Quality, Nuclear Context & Compliance
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 in all modelling activities.
Manage model revisions in line with document and model control processes.
Support responses to design reviews and construction queries related to RC detailing.
