Hitachi Solutions, Ltd. (Headquarters: Shinagawa-ku, Tokyo; President and CEO: Eiji Morita; hereinafter, Hitachi Solutions) has implemented the iPaaS "Workato," a single platform for all data integration and automation, for Shimizu Corporation (Headquarters: Chuo-ku, Tokyo; President and CEO: Tatsuya Shinmura; hereinafter, Shimizu Corporation), a major general contractor.
Under its "Mid-term DX Strategy," Shimizu Corporation has been working on building a data utilization platform as a core component of its strategy. However, the company faced challenges in integrating data scattered across various systems, including on-premise and cloud environments.
To address this, the company introduced Workato, which features over 1,000 connectors to link SaaS, on-premise systems, generative AI, and more, and proceeded with implementing data integration processes. With the support of Hitachi Solutions, Shimizu is now operating various automation recipes in-house and expanding use cases that leverage generative AI. For example, they have created a system that analyzes system maintenance notification emails with an LLM*1 and automatically notifies operations staff via a chat tool based on the level of urgency. The company has high expectations for Workato as its internal standard environment for data integration and AI utilization and is working to accelerate company-wide data utilization and AI-powered business automation.
Hitachi Solutions will continue to promote DX through the use of AI together with Shimizu Corporation, contributing to the realization of SX (Sustainability Transformation) management.

■ Implementation Effects
1. Integrated data scattered across diverse systems from on-premise to the cloud, achieving automation of business processes using AI.
2. Enabled on-site staff to develop recipes with no-code/low-code, promoting the in-house development of business automation by employees.
3. Built a foundation for future AI utilization that can flexibly integrate with various systems, while balancing development efficiency, reduced lead times, and governance.
■ Background
DX in the construction industry is an essential initiative from the perspective of improving productivity and addressing labor shortages. Shimizu Corporation has been promoting DX under the concept of a "Digital General Contractor" within its "Mid-term DX Strategy." Among its various initiatives, the construction of a data utilization platform is a key measure that forms the core of these efforts.
Previously, because data was dispersed across multiple systems, the company struggled to identify the location of necessary data and who to contact, leading to significant time spent on data extraction. As a first step in developing its data utilization platform, the company introduced a data virtualization solution to create an environment for managing the latest and most accurate data. However, as data utilization advanced, cases that could not be handled, such as large-scale data collection and processing, and data integration between cloud services, became apparent.
Therefore, Shimizu Corporation adopted Workato, which can connect various systems, with an eye toward establishing in-house development by employees. The company's decision was based on Workato's extensive connectors and ease of development, as well as the rich expertise possessed by Hitachi Solutions.
■ Customer Comment
We have received a comment from Mr. Yoshitaka Okazaki, Manager of the Advanced Technology Application Department, DX Management Promotion Office, Shimizu Corporation.
"Hitachi Solutions shared their own experience of using Workato, which gave us a sense of security. In the future, in addition to its use as a data utilization mechanism, we are also planning to use it as an AI agent environment. To handle diverse use cases, we want to continue thinking and working together with Hitachi Solutions, who possess a wide range of knowledge."
