Productivity Measurement for the Anti-sliding Pile of Xiluodu Hydropower Project

Abstract

In recent decades, there has been a huge rise in the amount of investments and resources put into hydropower construction projects. Thereupon, it is becoming an urgent need to study how to estimate the input so as to control total cost effectively and utilize the resources adequately. With that in mind, this paper introduced the process of construction productivity determination for the anti-sliding pile of Xiluodu Hydropower Project, as a typically measured object. The determination work includes: choosing timing observation method to measure labor and machinery productivity; selecting real-time writing method to measure material productivity; then adopting probabilistic evaluation method to analyze the obtained data resulting from construction productivity; finally forming the consumption quota per unit pile length through comprehensive arrangement of the above steps. Significantly, the research conducted may provide a platform for both the related researchers and practitioners to appreciate the construction and measurement processes of the anti-sliding pile and may pave the way for builders and managers conducting similar projects in future to gain a clear understanding of the efficiency and cost control.
