Pricing water proofing against a live tender

Mapping a tender BOQ to the right schedule items, applying the current cost index, and catching where rates have moved since the base edition is slow and easy to get wrong. Arched's estimation engine reads the tender, maps it to the applicable schedule, and flags where the numbers are exposed before submission.
