Costain-Skanska Joint Venture Redlining

The Redline drawing review process used by Crossrail is heavily paper driven, time intensive, and easily leads to confusion – particularly when information is required to be accurately captured from the field and then used to create as-built redlines and reports. 

The original process without BaseStone included printing up-to-date drawings, marking up by hand, and then submitting for approval, which could often lead to a rejection depending on the quality and clarity of the hand-drawn redline. This process is time-consuming, difficult to manage and often results in communication errors.

With BaseStone Redline, As-Builts were created directly from the field and produced progressively during construction as and when changes were noted.

Final Redline As-builts were automatically generated quickly and easily, reducing both the admin burden of remarking up A1 drawings as well as the project’s overall carbon footprint.
