ON SITE — SCOPE REVIEW

Preconly is the estimating desk US contractors plug in when bids pile up. From a single-trade takeoff to a complete project estimate, we produce numbers you can put your name on, organized in CSI MasterFormat and priced for your local market.

Every estimate arrives in your Excel template with material, labor, and equipment broken out, plus clearly documented assumptions, inclusions, and exclusions. Nothing to rework, ready to mark up and submit.
