This paper investigates so-called “Design Assistance (sekkei kyoryoku)” by Japanese subcontractors. The elevator industry is focused as the typical industry indicating the clear difference of the task distribution between Japanese Design Assistance and the US Consultation. First, the tasks and responsibilities of subcontractors in Design Assistance are clarified. We confirmed the subcontractors provide the design information based on the Design Assistance free of charge. The subcontractors do not have a primal responsibility of their design information, especially to the owner of the project. It results in a confusion of responsibilities between the architect and the subcontractor. Second, two types of the information gathering process through the Design Assistance is confirmed. One is the information generated by the subcontractor and provided to the architect, such as drawings, specifications, analysis, cost estimation, and presentation images. The other is the information provided from the architect to the subcontractor. The Design Assistance is one of the best opportunities for subcontractors to acquire “needs” of the owners, which is typically not obtained by the sales department of subcontractors. It is utilized for the development of new products. Third, the difference between Design Assistance in Japan and Consultation in US are focused. In US, an assessment and inspection oriented service and project management service are available. There are far more significant opportunities in modernization than new construction. The elevator manufacturers and the vertical transportation consultants are separate entities, which make smooth information exchange difficult.
