※Development of "Non-wooden Building Valuation Support System (Clear Calculation)" nicknamed RECPAS AUTO 5 (LGWAN・AI-OCR)
The clear calculation of non-wooden structures in the valuation of buildings is an issue due to the large number of medium- and large-sized buildings to be evaluated and the large amount of work per building, so RECPAS is working on the development of a system for "RECPAS AUTO 5 (LGWAN・AI-OCR)". By introducing this system, which consists of a quotation reading process and a valuation criterion linking calculation process, it is expected to reduce the burden on the site and improve work efficiency. RECPAS released it in 2022.
