For contractors

PDF tools for contractors and estimators

Mark up plans, compare drawing revisions, run takeoff, sign change orders, and assemble bid packages — from any laptop, no desktop license.

Catch revision changes before they cost you

Vault Compare highlights what changed between drawing or spec revisions, so scope changes are spotted before pricing or building.

Markup, takeoff and sign-off in one place

Trade-colored markup, revision clouds, measurement and takeoff, plus signatures and initials for change orders and submittals.

Bid packages without the shuffle

Merge drawings, specs and forms into one PDF, reorder and rotate pages, and export a clean package to send.
