At Whitecroft, our BIM engineers are not only adept at using Autodesk Revit; they are also fully trained lighting designers. We believe this is essential. When you use our teams on your project, you can rest assured the whole lighting solution is being designed, assessed and managed by people who know the technology inside out and have a full understanding of your requirements.

- We can populate your BIM model with a full lighting design.

- All our BIM families are created in-house, so if bespoke models are required, we can deliver them.

- We use Relux to create design validation data that confirms your project’s compliance and supports your BIM model.

- Once the model is complete, we work with you to interrogate every element including quantity schedules, costs, energy validation, COBie data and delivery schedules.
