Contrac
Scan. Track. Deliver. Contrac is the Veldcoast platform for construction and manufacturing teams that need a reliable digital record of work completed in the shop, in the field, and everywhere between.
QR + NFC construction tracking
Turn every unit into a live job record.
Contrac connects physical tags to digital workflows. A worker scans a QR code or taps an NFC tag, authenticates, selects an allowed task, starts a session, and closes that session with notes and photos when the work is complete.
QR and NFC accessTwo ways to reach the same unit record, even when one tag is blocked or hard to scan.
Role-based tasksUsers see the work available to their group, reducing clutter and bad entries.
Proof of completionCloseout captures time, person, task, notes, photos, and the tracked unit.
Inspection triggersCompletion records can drive notifications, inspections, reporting, and payment controls.
How it works
A simple workflow crews can actually use.
Scan the tag
A QR code or NFC tag opens the correct POD, house, room, or unit record.
Start the task
The user selects an approved task and Contrac records who started what, where, and when.
Close the session
The user scans again, adds notes and photos, and marks the work complete.
Use the record
Teams can report status, trigger inspections, support pay applications, and preserve the delivery history.
For home builders
Apply the same proof-based workflow to slabs, framing, rough-ins, finishes, punch lists, and final delivery.
For subcontractors
Create a clean digital trail that shows exactly when the work was performed and documented.
