本文调查了日本分包商所谓的“设计协助（sekkei kyoryoku）”。电梯行业作为典型行业受到关注，表明日本设计援助与美国咨询的任务分配存在明显差异。一是明确了辅助设计分包商的任务和责任。我们确认分包商根据设计援助免费提供设计信息。分包商对其设计信息不承担主要责任，特别是对项目业主而言。这导致建筑师和分包商之间的责任混淆。其次，确认了通过设计协助的两种类型的信息收集过程。一是由分包商生成并提供给建筑师的信息，例如图纸、规格、分析、成本估算和演示图像。另一种是建筑师向分包商提供的信息。设计协助是分包商获取业主“需求”的最佳机会之一，而分包商的销售部门通常无法获得这种需求。它用于新产品的开发。第三，重点关注日本设计协助与美国咨询的区别。在美国，可以提供以评估和检查为导向的服务以及项目管理服务。现代化进程中存在着比新建筑更重要的机遇。电梯制造商和垂直运输顾问是独立的实体，这使得信息交流变得困难。
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.
