Abstract Technology in construction adopting Prefabricated Elements can be recognised as “Precast Concrete System”, in Western Countries, this system has been widely used in constructing Bridges, Office Buildings and Residential buildings. A Precast concrete construction system provides the advantages of construction effectiveness, high levels of quality control, saving of construction time, minimisation of skilled labour, reduced manpower requirement on site, and saving in formwork requirements when compared with the traditional construction method (cast in place). In Thailand, Cast in Place is the traditional construction system that has been mostly used till now. Precast Concrete Slab is only a part of prefabricated elements that is used widely in Thailand. Adopting of fully precast concrete systems are only a few parties in the Thai construction market. However, many factors have an impact on the adopting of precast concrete system. This paper is the primary study stage to present and analyse a conceptual model that accommodate the numerous factors impact on the adoption process effectiveness. The results from 160 construction industry professionals in Thailand are presented and the significant factors which impact on the adoption of precast concrete system have been determined through the numerous statistical analysis. The paper concludes with the refine conceptual model of the adoption of precast concrete elements and system.
