The Opportunity

You will ensure all digital outputs are accurate, coordinated, and compliant with client, project, and industry standards.

You will be responsible for reviewing survey data for design suitability and carrying out quality checks on models and drawings to maintain high technical standards across project deliverables.
Alongside technical delivery, you will support and mentor junior team members and apprentices, helping develop their BIM and CAD skills, while contributing to best practice sharing and continuous improvement within the team’s digital delivery processes.
