Open Communication

An office building visualised in a web browser through 3drepo.io, can be viewed and managed by all participants privately, in a conference call or at a face-to-face meeting.
All parties can interact, share and examine in completely new ways, providing consistent and significantly enhanced knowledge and understanding.

Collaboration and Insight

As exploration of the model continues, specialists and commentators are able to add value, insight or questions as to potential challenges, or opportunities.

In this example an issue is recorded: “Is there sufficient space between trunking and the ladder?”

Management and Control

Throughout the project review process, administration and authority levels allow different interaction according to designated roles i.e. Design Architect, Structural Engineer etc.

This provides a managed framework for all activity and ensures only the concluded actions can be closed by those with the correct authority.
