About the role
Are you a skilled Structural Steel Detailer / Technician who takes pride in developing precise, buildable modular structures? Join our growing modular building manufacturing and technical team, where you will bring structural concepts and steel frame designs to life. In this role, you will lead the structural CAD detailing, producing accurate 3D models and 2D steel fabrication drawing packs (utilising Revit and Advance Steel), general arrangement drawing packs, and connection layouts for our modern modular and portable buildings.
Beyond general drafting, your primary expertise will focus on modelling steelwork for in-house design and fabrication. You will work closely with external structural engineers, steel fabricators, and our production teams on the manufacturing floor. You will work within our advanced manufacturing facility in Chichester and occasionally support customer site projects across the UK. If you enjoy technical precision, 3D steel detailing, and seeing the direct impact of your design work from factory fabrication to final site assembly, joining our growing team is the perfect move for you.
Key responsibilities
- Structural steel detailing & modelling: produce complete 3D models and 2D structural steel drawing packs in Revit and Advance Steel, including General Arrangement (GA) drawings, frame layouts, cold-formed and hot-rolled steel section details, and structural connection drawings for modular buildings. Ensure seamless 3D model synchronisation (e.g., between Revit and Advance Steel) to automate drawing updates and prevent manual revision errors across drawing packs.
- In-house design for external engineering verification: apply sound structural detailing logic to build comprehensive 3D steel models in-house, preparing complete models and layouts to be issued to external Chartered Structural Engineers for calculation checks and final sign-off.
- Technical drawings & specifications: read, interpret, and translate architectural layouts, structural calculations, and technical installation specifications into clear, accurate, and well-annotated CAD drawings.
- Fabrication & shop floor support: work closely with the factory steel fabrication and manufacturing teams to resolve technical drawing queries, refine structural details, welding/connection details, and ensure designs are practical to fabricate.
- Revision control & updates: update drawings efficiently based on engineering feedback, factory mark-ups, and site changes while maintaining strict revision and document version control using integrated 3D CAD/BIM workflows.
- Approvals & document packs: prepare and issue drawing packs for structural approvals, Building Control compliance, and client sign-off.
- Material schedules & BOM: extract precise Bill of Materials (BOM), steel cut lists, and structural component parts lists directly from 3D models (Advance Steel/Tekla) to support procurement and production scheduling.
- As-built documentation: maintain accurate project technical records and prepare detailed as-built drawings upon project completion.
- Quality standard: aim for a "right first time" standard in drawing accuracy to minimise fabrication defects, rework, and site installation issues.
- Safety & housekeeping: work safely in line with Company Health, Safety, Environmental, and Quality systems, contributing to continuous improvement in design-to-manufacture workflows.
