In this study, to resolve several problems in actual inspection stage from the sites for establishment or revision of Construction Standard Production Unit-CSPU such as difficulty of casting objects for inspection from sites, lack of inspectors, etc, we developed Production Unit Module to apply for accessorial work or unproductive work which are occurred in construction process, from Gang-Form which is widely used in formwork for outer wall and we developed Cyclone model for Gang-Form Operation which is having Gang-Form. Also, we verified the application in actual work of Production Unit Module or cyclone Model which are developed in this study by comparing and analysing outfit Production unit through Cyclone Model of Gang-Form Operation and Work Sampling method in actual sites. From the result of comparing or analysing upon outfit Production Unit from Work Sampling and Cyclone Model, we found that both have approximate value within ${pm}5%$ so we can prove the actual application of developed Cyclone Model of Gang-Form Operation.
