Free tools
Small tools for everyday construction and design admin. Free, no account, and they run in your browser, so nothing you paste or open leaves your browser. We count tool clicks anonymously, never what you paste.
COI and license expiry checker
Paste or upload your sub insurance and license list. See what is expired (red), expiring within 30 days (yellow) and current (green), plus who you can schedule.
Schedule unit-mismatch checker
Paste a door, equipment or panel schedule export. Flags columns that mix ft, in, mm and m, unitless values, duplicate marks and blanks.
Bid leveling sheet
Paste each bidder's line items. Get a side-by-side comparison with missing scope flagged, low and high per line, spread, and totals adjusted for gaps.
RFI and submittal log aging checker
Paste your RFI or submittal log. See open items by age, what is overdue or due soon, who has the ball, and average days to close.
Need it automated?
AI agents and scripts can run schedule and IFC checks through the paid model export checker API.
