Rework in construction typically costs about 5% of the overall contract value. And the time overruns are worse, at roughly 7.1% of total work hours. These overruns impact relationships between trade contractors, general contractors, and owners, which makes it crucial to reduce and avoid rework. Drone and Crane Camera progress monitoring can reduce the rework by 20-25% by bringing real-time as-build data to help contractors identify a conflict in project designs and avoid unnecessary rework.
