Time-lapse photography involves a series of still pictures taken at 1- to 4-second intervals by a special camera from a fixed location. This process provides an accelerated view of the construction process compared to real-time video recordings. This type of recording shows the flow of the process but not the details. Time-lapse photography is used primarily for information in disputes, showing the sequence, equipment, and flow of the project; in productivity studies, showing the effect of jobsite layout and facilities; and in public relations for the contractor, showing how the facility was constructed.
