Abstract: According to the Construction Industry Act, constructors are classified into comprehensive constructors and specialized constructors. In this study, the authors surveyed the actual situations regarding the increase in demand for the maintenance and repair of deteriorated social infrastructure, the number of orders for maintenance and repair and the contract amount received by constructors in each capital range, based on statistical data analysis, questionnaires, and interviews. Then, it was found that most of general maintenance and repair works are undertaken by specialized constructors with a capital of 10 to 50 million yen. The authors also mentioned that it is desirable that (1) specialized constructors take central roles in maintenance and repair works, according to the government and public office demand law, (2) with this, it is possible to reduce the incompleteness of maintenance and repair works, and (3) design and construction are ordered together. On the other hand, it was pointed out that specialized constructors are required to possess not only technical expertise, but also the ability to manage all construction processes.
