The full set of tools for engaging in BIM look like this (so far):
Autodesk Infrastructure Suite.
Strategy, processes and manuals.
Adobe products for graphics and layout.
Web services for sales
Sharepoint and local area network storage.
Solibri for validation
Government Portal Extranets
Mind mapping software
Skype, Webex and Lync
Point cloud manipulation
Installation, commission and maintenance tools
Post it notes
Red felt tip pen
Time tracking software – Manic Time and Rescue Time
Like it or not this is the reality of a live project and getting information to flow through all these tools and stay useful and relevant is one of the biggest challenges.
