| Abstract |
Earthwork is executed to provide a space for facility structures, and plays an important role in the construction operation. Contractors usually put a combination of construction vehicles to execute the earthwork operation. These construction vehicles need to interface with each other for productivity improvement. The objective of this study is to prototype an earthwork supportive system for information interface between construction vehicles. The study is conducted in a sequence of 1) analysis of information interface during earthwork; 2) data modeling of earthwork attributes; and 3) development of a prototype for the earthwork supportive system. The output screen images of the prototype show that the earthwork supportive system can improve communication between construction vehicles by facilitating information interface during earthwork. |
