Our in-house Digital Construction team employs advanced visualisation techniques tools to demonstrate our understanding of the design intent and to manage clash detection, buildability analyses, construction sequencing, take-off estimates, asset management, and other factors of the process.

  • 3D scanning/modeling
  • animation
  • 3D printing
  • augmented reality

We recognise that the benefits of BIM apply to both public and private-sector projects. We have found that combining two disciplines into one department, in-house, ensures that accuracy and interoperability through virtual construction is seamless and consistent throughout the life of the project. It is our quest to implement the powerful benefits of BIM and animation on all of our projects.
