Project reporting

Manage your project with Vahalo

Vahalo is a proprietary, cloud-based reporting and document management system that connects the construction team to the Special Inspections details of the project. Matrix field personnel upload inspections and findings directly from the field, and your team gets direct access to project-relevant data in real time.

Tracks open items

Each Field Inspection Report carries forward open items from previous visits.
Documents with photos

Photographs are captured at the time of inspection, each with comments and dates.
Delivers a PDF instantly

The report converts to PDF automatically when saved in the field, for every type of inspection.
