Senior CAD Technician - Wet Utilities

The Senior CAD / Plant 3D Modeller role is focused on high‑quality CAD and 3D modelling production for water and wastewater treatment projects supporting Sweden/Nordic delivery teams. The position requires deep technical expertise in Autodesk Plant 3D, strong attention to detail, and the ability to collaborate effectively with engineers and cross‑functional teams.

• 3D modelling: Develop and update piping and equipment models in Autodesk Plant 3D (2022 or later) based on P&IDs, layouts, vendor drawings, and engineering inputs.


• Drawing production: Generate orthographic drawings, general arrangements, sections, elevations, and piping isometrics.


• P&ID development: Prepare smart P&IDs and support updates under engineer direction.


• QA and standards: Ensure compliance with ISO, SSG, SIS standards; deliver models in accordance with LOD up to 400; apply QA processes to own and others’ work.


• Pipe and support modelling: Model piping systems, valves, supports, and local steel items per ISO/SSG standards.


• Hydraulic profile: Support creation of hydraulic profiles and integration into models.


• Spec and reporting tools: Active use of Plant Spec Editor and Plant Report Creator.


• Pressure/stress analysis: Perform or coordinate pressure control and stress analysis using ROHR2, CAESAR II, or similar tools.


• Clash detection: Use Navisworks for model review, walkthroughs, and clash checking.


• Material take‑off: Extract BOMs, line lists, and MTOs from models.


• Collaboration: Work closely with engineers, BIM leads, and cross‑discipline teams; communicate technical solutions clearly.

• Diploma/Bachelor’s in Mechanical Engineering, Drafting, or relevant technical discipline.


• 8–15 years of CAD/piping detailing experience, with at least 4–5 years hands‑on in Autodesk Plant 3D.


• Proven experience in water/wastewater projects, piping systems, and treatment skids.


• Familiarity with Swedish/Nordic codes and standards (ISO, SSG, SIS).


• Experience across design and construction phases.


• Exposure to point cloud/Recap workflows for brownfield projects desirable.

Essential Skills

• Advanced Autodesk Plant 3D modelling and AutoCAD 2D drafting.


• QA process knowledge and ability to deliver models to LOD 400.


• Strong command of orthographic/isometric drawing extraction.


• Ability to prepare ISO drawings for pipe routing, weld points, prefabrication splits, and BOM adjustments.


• Effective communication and teamwork across disciplines.

Soft Skills & Attributes

• Attention to detail and disciplined approach to modelling.


• Initiative in quality assurance and proactive resolution of technical issues.


• Strong communication skills; ability to explain technical solutions clearly.


• Positive attitude to training, standardization, and mentoring junior CAD staff.


• Team‑oriented mindset with adaptability to project needs.
