Highway Construction Productivity Measurement with a Wireless Real-Time Productivity Measurement System

Because the quantity of work is relatively easy to estimate accurately by using printed drawings or computer-assisted drafting system and specifications, the accuracy of the duration depends largely on the accuracy of construction productivity. It is not difficult to understand why a scheduler without accurate productivity data is unable to produce a reliable cpm schedule. In summary, poor productivity data affect the accuracy of activity duration; inaccurate activity duration makes it impossible to produce a reliable construction schedule. To improve the quality of construction schedules, there is a need to develop an advanced productivity measurement system that will overcome mentioned shortfalls.
