Ricoh Japan Corporation (President and CEO: Toru Kasai) will begin offering the Scrum Asset 'Construction Industry Hierarchical Estimate Creation Model', which standardizes and streamlines estimate creation work in the construction industry, starting April 6, 2026.
With the revised Construction Business Law, fully enforced on December 12, 2025, contractors are now required to create estimates that clearly specify breakdowns of labor costs and necessary expenses, ensuring appropriate labor costs. Consequently, creating estimates that properly explain the basis of the estimation to clients has become crucial for contractors.
In the construction industry, 'hierarchical estimation*', which calculates the estimated amount while organizing construction and work details into a hierarchical structure, is commonly adopted. However, the reality is that creating estimates optimized for each site using Excel or Access has become commonplace. This situation leads to discrepancies in the accuracy of estimates within an organization and the creation of estimates that do not meet the requirements of the legal revisions. Therefore, it is necessary to standardize estimate creation work and eliminate reliance on individual skills so that anyone can create a hierarchical estimate of the same quality, thereby building a system that can reliably present the basis of the estimate to the client during contract negotiations.
* The entire construction process is broken down into a tree structure such as major, medium, and minor items, and quantities, unit prices, and amounts are set for each item and accumulated to create an estimate.
The 'Construction Industry Hierarchical Estimate Creation Model' utilizes 'CELF' provided by SCSK Corporation. 'CELF' is characterized by its ability to build business applications without coding while maintaining operability similar to Excel. This model provides an application that can create hierarchical estimates using 'CELF' as a template. It is also possible to import estimates in various formats, such as CSV, received from partner companies and utilize them to create hierarchical estimates. Even those with little experience in creating hierarchical estimates can efficiently do so, realizing the standardization of estimate creation work in the construction industry. In addition, it provides applications for profit confirmation and invoice creation as templates, and can be linked with other systems such as the cloud service 'MakeLeaps' that streamlines invoicing operations, and core systems, contributing to the efficiency of peripheral operations related to estimating.

Furthermore, on February 27, 2026, the company also began offering the Scrum Asset 'Construction Industry Received Invoice Digitalization Model', which streamlines payment operations in the construction industry and contributes to the optimization of payments to subcontractors. In the construction industry, improvements in transaction conditions across the entire supply chain are progressing, and prompt payment of transaction fees from consignors to small and medium-sized consigned businesses is required. By combining the 'RICOH IM C6010SD' series of multi-function printers that can scan irregular-sized forms in bulk, the 'RICOH fi Series' commercial image scanners that can be placed on a desk and support scanning of irregular sizes and special papers, and the content management service 'DocuWare' that supports corporate operational efficiency, this model streamlines the digitalization of forms and form processing between on-site staff and accounting staff, supporting faster payment operations.
