Abstract
This paper describes statistic analysis of time schedule of separate works for construction of prefabricated apartment houses of five stories. Standardized thirty-one works of the network frame of fourty-six projects were investigated, and the results obtained are as follows : (1) Linear relationship between construction period and the number of housing units or the number of buildings was observed. (2) A statistical linear model was established, and a regression equation was obtained for estimating time schedule of separate works by employing these as decision variables. (3) From this equation, a calculating diagram which enables predicting time schedule from insufficient information obtained at the stage of expecting an order was drawn.
