Technologies Used
BIM 3D, 4D (schedule), and 5D (cost)
Centralised data environment shared among project partners
Digital clash detection tools
Key Outcomes
Improved collaboration and reduced design clashes before construction
Shortened project delivery times by minimising rework and delays
Reduced cost overruns and improved lifecycle planning for assets
Impact
Crossrail’s BIM implementation is considered an industry benchmark, proving that complex infrastructure projects benefit significantly from smart digital workflows.
