Measuring construction productivity using the write system
Abstract
To overcome the limitations of existing on-site construction productivity measurement techniques, a wireless real-time productivity measurement (WRITE) system was developed. Major components of the WRITE system include a digital camera, a video camera, a data processor, an AC transformer, a computer, and wireless modems. Researchers developed the framework of the WRITE system first. Then, a prototype of the system was built in the laboratory. Finally, the prototype system was tested for accuracy in three highway projects. Statistical analysis results proved that the developed system generated identical productivity measurements compared to the stopwatch method. The WRITE System has several unique advantages. First, there is no disruption to construction operations. Second, the onsite construction productivity can be determined in real-time so that the project manager will be able to take action immediately if necessary. Third, the collected data can be shared by all parties in the construction project via the Internet at any time and at any location. These advancements help to enhance the contractors' capability of managing construction projects. Copyright ASCE 2009.
