A Study on the Work Crew Based for the Estimation from Construction Analysis of Cement Liquid Waterproofing in Apartment House

This study aims to make improvements to the standard estimation process used to estimate reasonable costs for construction work, and to suggest a work crew based estimation using a new cost estimation model. In addition, work crew shift combination and construction process were systematically organized in order to improve the estimation technique and the construction capability of the cement liquid waterproofing work for apartment buildings. In addition, in terms of manpower and productivity, analyses were performed on the cement liquid waterproofing work for apartment buildings with net areas between and , and the results were then compared with those calculated using the conventional work-crew based estimation method. Through this study, when the results of this study and those calculated by the conventional method were compared, for apartments with the net area of , the differences between specialists were shown to be 1.91 times to 2.13 times on average, while they were 8.82 times to 9.52 times between normal workers on average. For apartments with the net area of , the differences betweenspecialists were shownto be 1.89 times to 2.07 times on average, and 8.57 times to 9.38 times on average between normal workers.
