In 2025, the construction industry’s business practices will undergo a dramatic change! A thorough explanation of the key points of the revised law, such as the obligation to specify labor costs in estimates and the rules for contract changes, along with practical responses.

2025 Construction Industry Law Amendment Seminar In the former Shimoma and Shimoshimoma estimate formats, the inclusion of "work rate × labor unit price" is required, and contracts must clearly state the method for changing amounts when material and labor unit prices rise. This seminar will explain the key points of the amended Construction Industry Law that will be enacted in 2025. In the context of addressing the labor shortage in the construction industry and improving worker treatment, business practices will change significantly, including recommendations for standard labor costs and the prohibition of contracts below cost. In particular, understanding changes directly related to practice, such as the obligation to provide information on material price risk and the prohibition of construction period dumping, is essential. We will also provide detailed explanations on building a new estimating system and measures to adapt from IT to digitalization. This course will be held in a web format using Zoom and is part of a common accredited program such as the Construction CPD Information Provision System. Let’s start preparing now to correctly understand the legal amendments and survive in the rapidly changing construction industry.
