No more paper chaos, unsorted WhatsApp photos, or costly invoice deductions. TekEx Field is the mobile extension of the TekEx B2B platform and the ultimate tool for the digital construction file in fiber and broadband rollout. A proven industry standard, the app is used by numerous construction companies, engineering firms, and general contractors. Thanks to its scalable multi-tenant system, general contractors effortlessly manage hundreds of subcontractors and thousands of accounts centrally in a single environment. The app that thinks ahead Forget tedious searching for the right address. TekEx Field automatically detects the nearest building or distribution point (NVT) via GPS. The technician opens the camera, and the app shows exactly which mandatory photos the current workflow requires (e.g. open trench, warning tape, asphalt reinstatement). Key features at a glance: • ZTV43- and VOB-compliant documentation: Every photo is permanently stamped with GPS coordinates, viewing direction, and timestamp. • 100% offline-first: No signal in the trench? No problem. All data is captured locally and synced in the background as soon as coverage returns. • Enforced workflow requirements: The app blocks the completion of a construction section until all mandatory photos requested by the site manager have been taken. • Digital protocols (fiber house connection): Fill out house connection inspections and acceptance reports directly on the smartphone and have the customer sign on the spot. • Real-time tracking: General contractors and site managers see the progress of the route and of their subcontractors in real time in the web dashboard. Who is this app for? TekEx Field is aimed exclusively at B2B users in infrastructure and utility construction: subcontractors, construction crews, foremen, and general contractors. IMPORTANT NOTE: To use the TekEx Field app, an active company workspace on the TekEx web platform is required. Sub-users receive their login credentials directly from their client.
