civil 3d designer

Role Summary & Scope

You will be responsible for producing detailed, multi-disciplinary highway designs from early-stage concepts through to final construction packages.

Your day-to-day focus will be hands-on 3D modeling, drawing production, and providing direct technical support to both the design and on-site construction teams.

The design scope of works will include, but not be limited to:

• Pavement Design: Modeling complex structural pavement build-ups and resurfacing layouts.
• Kerbing & Footways: Detailed modeling of custom kerb lines, channel lines, and footway profiles.
• Earthworks: Corridor earthworks, cut-and-fill calculations, and surface-to-surface volume analysis.
• Drainage: Modeling highway drainage networks, attenuation, gullies, and catchpit runs.
• Section 278 (S278) Works: Designing compliant highway modifications to interface seamlessly with existing local authority networks.

Key Responsibilities

• Hands-on 3D Modeling: Develop detailed AutoCAD Civil 3D models, including alignments, profiles, assemblies, corridors, and finished surfaces.
• Drawing & Detail Production: Prepare and update technical drawings, construction details, schedules, and material specifications.
• Drainage & Pavement Modeling: Assist in the hands-on design and modeling of highway drainage networks and pavement layouts.
• Traffic & Signage Design: Utilize KeyLines and KeySigns software to design compliant road markings, signing schedules, and traffic management layouts.
• Construction Support: Work collaboratively with the co-located construction team, resolving technical design queries and updating redline/as-built drawings.
• Standards Compliance: Ensure all design models and drawings comply with relevant technical standards, local authority requirements, and client specifications.

Requirements

• Technical Expertise: Advanced, expert-level AutoCAD Civil 3D skills are essential (corridors, earthworks, drainage modeling, and complex junctions).
• Highways Knowledge: A strong understanding of highway and traffic engineering principles with a proven track record in a dedicated highways design role.
• S278 Experience: Strong familiarity with Section 278 delivery and local authority design approval processes.
• Industry Standards: Good working knowledge of DMRB, MCHW, Traffic Signs Manual, and the TfL Streets Toolkit.
• Software Proficiency: Experience using KeyLines and KeySigns for road markings and signage design.
• Education: HNC/HND or Degree in Civil Engineering (or equivalent technical design qualification).
• Experience: Minimum of 3-5 years of dedicated experience in a civil infrastructure or highway design capacity.
