Full control and better collaboration for project contracts and specifications

Improve productivity and reduce risk for construction and engineering projects.

Project contracts carry huge commercial risk for both parties and can be even more complicated for multi-party alliance contracts. The documentation often runs to many hundred of pages including the standard forms, specific provisions, specifications and procedures. Dozens of people need to be involved in preparing, negotiating and amending drafts. Controlling change and knowing who edited what and when is essential for a smooth change control process and can be essential to efficient resolution of disputes.

Barbal’s founders started their careers in the construction and infrastructure sectors. We know just how important contract management is to project success and how expensive it can be when it goes wrong.

Barbal’s Document Drafting System reduces the cost and delay of collating, reviewing and approving contract documents and gives a full history of how the constract evolved from inception through to completion. It means that everyone can quickly review changes and nothing can slip through the gaps.
