Cost analysis of skim coating activity on three type of wall surfaces

Abstract

Abstract

This research studied labor productivity and cost per square meter of skim coating activity on three types of walls. They are concrete wall, light aggregate wall panel, and typical plastering wall. The study examined direct cost, indirect cost, and productivity of skim coating work on the three wall. Data are collected daily from three construction projects including duration, number of labor, material, and equipment. They were recorded to analyze the direct and indirect cost. In addition, a learning curve model was used to analyze the steepness of the learning curve to estimate time of work for future projects for work planning, increasing confidence in project bidding, and reducing risk of loss from entering contracts.

Keywords: Cost, Labor cost, Learning curve model, Wall plastering
