Unearth Technologies develops place-based productivity and collaboration software for the construction industry. Their OnePlace platform unifies construction’s disparate data sources with a “mapify-ed” interface that demolishes information silos and builds simple communication. Most construction software development has focused on point solutions, platforms targeted at solving one issue like photo capture, plan management, or timekeeping. Unearth seeks to eliminate the burden of multiple softwares by offering an all-in-one reality capture platform, that also eventually integrates with all digital data to give a single source of truth. AGC member since 2018.
