Facilities teams need comparable scopes that account for existing condition, operations, equipment, and closeout. A material-and-area summary may not expose important differences. Each bidder should state assumptions and deviations clearly.

What to do next

Provide a common project brief and require a response to the same scope items. Compare preparation, drainage, transitions, phasing, and exclusions. Resolve technical differences before using the final totals as the primary selection criterion.
