Luke Miller

Luke Milner – Mechanical Projects Engineer
Luke literally provides another dimension to our Technical and Design Team. Luke’s experience in 3D CAD has enabled NTS UK to provide very clear 3D modelling and visualisation presentations. This enables our design team to ‘walk through’ their designs at a very early stage in the process to understand and ensure that all the site constraints have been fully understood and dealt with. It also clearly helps NTS communicate the design to the clients team to ensure full understanding of the scheme. Feedback from this service has been excellent, the install teams particularly appreciate being able to clearly visualise the project and interrogate any potential issues at early stage.
