Work with our innovative, interactive plan to gain visibility and save time. ID-driven technology enables connected construction management. With our platform-based application, you can intuitively control your projects through the interactive map. built[t] construction offers you an app with diverse functionality and intuitive operation: * record quality issues * record localized information * document performance statuses * create elements such as doors, penetrations and general monitoring points * distribute responsibilities or write feedback * release tasks Benefit from improved documentation and your new digital memory, developed with 25 years of experience in the highly dynamic process of construction. Traditional digital quality-management-tools do not have located IDs. Until now, only points are set on a PDF-based background. With our technology, dates, places, times and people are linked to the corresponding ID. Your process is permanently documented and accompanies you throughout the entire project. Individual requirements, e.g. "Lean Management", can be realized cost-effectively and quickly with our product built[t] solution. These module-additions extend your existing standard built[t] construction products. If you are interested, please contact us at info@builtt.de Credits: Video: Nils Hauke Neuer
