Steel construction buildings generally use conventional systems with the main element is a standard wf hot rollet which we often encounter in the market, usually heavier than non prismatic where fabrication is carried out in the field. Pre-engineering building steel construction method is a construction method developed to produce cheaper steel construction, efficient and fast implementation by minimizing the risk of errors, and producing erection methods that can be done in stages, relatively easily and quickly. This study was conducted to determine the value of the cost efficiency of the PreEngineering Building design towards conventional design as an alternative design. This research method is carried out based on two stages, namely, literature studies from related institutions as a basis for problems and direct observation methods. The cost analysis process of the PreEngineering Building design and conventional design uses secondary data that is in accordance with the conditions in the field so that the resulting cost efficiency can approach the actual situation. It starts by looking for differences in the weight of steel construction to the cost factor in the two constructions. In the end we can find out the extent of the cost efficiency of the Pre-Engineering Building design towards conventional designs. From the results of the analysis, the total cost of the Pre-Engineering Building design is obtained more efficiently with a difference of Rp.3,850,122,944.85, – from a conventional design with a percentage of 3.29% of the project value.
