Mobile app for subcontractors and field teams
With UBIX-SOFTWARE construction site management software, give your subcontractors secure, dedicated mobile access to their assigned project scope. Each external contractor can submit field information, log their hours, and send documents without having to go through the office.
Your subcontractors are brought into your workflow, with no administrative complexity.

How UBIX-SOFTWARE brings subcontractors into site tracking
Subcontractor access in UBIX-SOFTWARE follows a simple, secure process. Every external contractor gets a dedicated space, limited to their scope.
Invitation and set-up of subcontractor access
The site manager creates the subcontractor account in UBIX-SOFTWARE and assigns the rights matching their assignment. The contractor receives an invitation and gets immediate access to their space from the mobile app.
Viewing site tasks and documents
The subcontractor views drawings, checklists, safety instructions and documents attached to their assignment from their tablet or smartphone. They have all the information they need before even arriving on site.
Reporting on-site information
The contractor reports in real time from the mobile app: geotagged photos, site reports, field readings and any issues found. The site manager receives the information without delay.
Validation and close-out of the job
The site manager validates the information submitted by the subcontractor, closes out the job and generates the acceptance report. Full traceability of the work is kept in the site file.
Features included in the subcontractor mobile app
Secure, ring-fenced access
The subcontractor only accesses information relevant to their assignment. Your confidential data stays protected.
Access to site documents
Drawings, instructions, checklists and reports are accessible directly from the mobile app, even without a connection.
Geotagged and time-stamped photo uploads
The subcontractor documents their work with photos automatically located and dated for full traceability.
Site reports
The contractor writes their site report from the mobile app. The site manager receives it in real time, with no back and forth.
Time tracking on site
The subcontractor clocks their arrival and departure times from the mobile app. Data is centralised with no re-entry.
Electronic signature
The subcontractor signs acceptance or validation documents directly from their tablet or smartphone. The signature is time-stamped and archived.
Reporting issues
Every non-conformance or incident spotted by the subcontractor is reported in seconds and assigned to the relevant manager.
History of work carried out
All of the subcontractor's work is archived in the corresponding site file and can be viewed at any time.
Works without a network
The mobile app works offline. Data entered on site syncs automatically as soon as a connection is available.

The benefits of using UBIX-SOFTWARE to manage your subcontractors

The subcontractor uses the same app as your in-house teams. No third-party tools, no double entry, no information lost between contractors.

Fewer communication errors
Instructions, guidelines and documents are sent directly from UBIX-SOFTWARE. The subcontractor has the right information at the right time.
Time saved on administrative management
Time tracking, site reports and acceptance documents are all managed in a single tool. No more emails, chasing up or manual re-entry.
Real-time oversight of subcontracted work
The site manager can see the progress of subcontracted work in real time, from the office or from the field.
