Tóm tắt

A scheduling and progress control system called Photo‐net is introduced where a digital movie of construction activities can be played back along with an animation of as‐built vs. as‐planned performance of these activities. A technique to make time‐lapse digital films of construction activities is used. A method to store a digital film is developed allowing thousands of pictures to be stored and managed in a Windows environment. A program is developed that generates critical path method (CPM) derived bar‐charts. A recording system is devised enabling the user to specify the day‐by‐day progress achieved in construction activities, allowing the program to link the playback film with the progress observed on the construction site. A set of input screens are generated by the system that provide a friendly, intuitive and easy way to enter project data. A case study is presented where the system is used, the performance of the system is discussed and the results are analyzed.
