Rail & metro
Every rail and metro package, read as one record.
Civil, track, systems, and rolling stock packages run on different contracts with different contractors. Infiny reads all of them, with the letters and programmes between them, so you can trace an interface delay from one package to the next.

The challenge
Where rail & metro programmes lose time and money.
- 01
Interfaces between packages
A late formation handover on the civil package becomes a track delay, then a systems delay. Each contractor holds a different piece of the story.
- 02
Records that span a decade
Corridors and metro lines run for years. By the time a claim is assessed, the people who wrote the letters have often moved on.
- 03
Access, blocks, and possessions
Land handover, traffic blocks, and utility diversions decide entitlement, and the proof usually sits in hindrance registers and site diaries.
Contracts & documents
Built for the forms rail & metro runs on.
Infiny reads the contract and the project record together. It knows where each form sets notices, time bars, and entitlement, and it finds the facts that trigger them.

“We can now map an entire chronology across thousands of pages in minutes. It moved our workflow from searching for facts to strategising around them.”

“Faster cross-referencing of provisions, pleadings, and evidence lets me focus less on searching and more on reasoning.”
