Senior As-Bulit BIM Modeller

This role is responsible for leading the production, validation, and integration of Stage 5 and As-Built deliverables, ensuring full compliance with HS2’s BIM and As-Built specifications. Working under the direction of the As-Built BIM Manager and Area BIM Leads, this position supports model updates across shafts, headhouses, and associated assets, ensuring that live Project Information Models (PIMs) accurately reflect redlines, field changes, and progressive construction status.

Flexible working: We welcome you to ask about the flexibility you need. This might be part-time, remote working, or compressed hours for example. Anyone who applies for a role can ask about flexibility at interview. In return, we will explore what is possible for the role.

Main Responsibilities

• Maintain and update live Stage 5 3D models in coordination with field, design, and supply chain teams, ensuring changes are validated and traceable.
• Lead the coordination and integration of as-constructed data including redlines, point clouds, FCDs, and survey outputs into the federated model.
• Ensure all model updates are in alignment with the HS2 As-Built Specification (HS2-HS2-IM-SPE-000-000009) and project BEP.
• Support DAC submissions by preparing graphical model data that meets required MPDT standards and is fully aligned to asset metadata and HS2’s AIM expectations.
• Guide and mentor junior modellers and technicians to maintain modelling consistency, naming standards, and graphical integrity.
• Drive issue resolution between construction and design inputs through active clash detection and model review cycles.
• Collaborate with Asset Information Coordinators to ensure asset relationships, classifications, and identifiers are correctly attributed and validated.
• Support fortnightly model review cycles, providing assurance documentation and inputs to design freeze processes.
• Liaise with ProjectWise and EMT systems to manage model uploads, status tracking, and evidence submissions.
