Optimization is used by operations research methods which are solved by Integer Programming Software QM for Windows version 2.1 and is based on the development of a housing fictitious data X type-36 in Banjarmasin. The objective of this research is to optimise the use of a given building area by assigning different types of sub-structure subject to a number of constraints. This condition requires that developers be more selective and perform optimisation in choosing types of soft-soil foundations to ensure maximum profit from the building investment. The condition of soil in Banjarmasin which is dominated by wetland with a soil bearing capacity of as low as 0.2 kg/cm2 means that buildings require costly foundations.
