This paper presents a study on selecting the optimum construction method for building projects with deep and large-scale underground work. Here illustrated (H building project) : an approach to be used in the preliminary phase of structural design and construction planning. Highlighting the underground work, statistical discriminate analysis proposed previously by the authors has been carried out. Adopting this analysis, the comparison study for both cost and construction program have been made in regard to three construction methods, that is, (1) Top-down construction procedure ("SAKAUCHI METHOD") (2) 1st floor slab concreting in advance plus combined H-section strut method ("IKKAI-YUKA SENNKOU SHUUCHUU KIRIBARI METHOD") (3) Conventional concreting procedure ("JUNUCHI SHUUCHUU KIRIBARI METHOD") To the final solution, a brief description of the SMW design and rationalization/labor-minimization by Top-down construction procedure ("SAKAUCHI METHOD") is given.
