Cloud-based estimation and quotation for the construction industry [Raku Oh! Workspace]
Is that calculation still done manually?
The construction industry web service "RakuOh! Workspace," which inherits the functions and know-how of "Hiroi-kun" and "Rakuou," has been significantly renewed, centralizing everything from item extraction to estimate creation in the cloud. It can be used with just a credit card registration, and there is no need for complicated installations, making it easy to get started. AI features are also planned for release by the fiscal year 2026. 【Item Extraction Function】 ◆ Bulk Extraction Simply click on the drawings to extract lengths, areas, and wall areas all at once. Subtractions for windows and doors, as well as the perimeter of sashes, are automatically calculated. ◆ Save Custom Extraction Methods Extraction rules can be registered and retrieved. Registering materials helps standardize work and eliminate dependency on specific individuals. 【Estimation Function】 ◆ Import Extraction Data The quantities calculated with the "Extraction Function" can be directly imported into the estimate. This eliminates the need for transcription work, creating a seamless flow from item extraction to the estimate document. ◆ Customization of Calculation Formulas and Forms, Master Management Utilize the customization features for calculation formulas and forms, as well as master functions, to easily create estimates that fit your company's rules and layout. This prevents price variations among responsible personnel and maintains stable estimation accuracy.

At Ark System, our mission is to aim for coexistence and mutual prosperity as "the best partner for our customers." We have been involved in solutions across various industries such as construction, finance, public services, and distribution, engaging in system development and system consulting. We continue to provide proposals and support tailored to our customers' needs, building trust between people and growing together with our customers. Utilizing the technology and know-how cultivated through our business, we developed the "Rakuou" series of estimation software for construction operations. This software supports various industries, including architecture, electrical, and mechanical equipment construction, significantly streamlining the process from takeoff to estimate creation. Currently, it has been adopted by over 2,100 companies, including major general contractors. In addition to our flagship model "Rakuou 3," we also offer subscription versions that are easy to start and continue, such as "Rakuou Link" and "Rakuou Crew." For takeoff tasks, we provide "Hiroi-kun III," which allows for easy extraction of lengths, areas, and quantities with just a mouse click from drawings. We have also launched a subscription service that can be started casually from ¥3,800 (tax included) per month. We aim to improve our customers' operational efficiency and productivity, creating a comfortable work environment.
