This study attempts to apply the predetermined time standard(PTS)method to building production. This paper describes a time standard system based on the Maynard operation sequence technique (MOST), which is an up-to-date method in PTS. 0ur conclusions are summarized as follows. 1)MOST can be applied to various sorts of building work and manhours can be calculated to within ± 10% by making appropriate modifications. 2)By using MOST, an adequte time standard for building work can be constructed, and also systematized in computer. 3)A simulation of manhours in studies of work method, and calculating manhours in studies of building construction and construction method, are possible by using this time standard system.
