In an architectural construction, underground construction is a critical path forming a major part of the total
construction period and cost, and particularly in big cities, its size has been increasing every year. A basement
wall currently constructed in the field needs a largefunctional work force, and the construction is under progress
by the Euroform and Soldier system, which is disadvantageous in terms of the construction period. Therefore, in
this research, non-supporting forms which are applicable to the buildings construction were developed, based on
the non-supporting forms partly used in some civil engineering works. In addition, the size of a form was
assumed and its economical efficiency was compared to that of the Euroform and Soldier system which is used
most in construction fields, and the results were analyzed. The study results showed that the construction cost of
composite non-supporting forms was higher than that of the Euroform and Soldier system byabout 8%, and the
construction cost of non-composite non-supporting forms were lower than that of the Euroform and Soldier
system by about 9%. However, in the case of composite non-supporting forms, the amount of concrete and
reinforcing rods remarkably decreased in structural construction, so it has the effect of an economical cost
reduction compared to the construction cost of existing walls by about 35%
