Topcon releases “Rakuzumi (楽墨)” Smartphone Software for Construction
Topcon Corporation has launched a smartphone application software called “Rakuzumi (楽墨)”, designed specifically for construction sites. This software is available in a subscription-based model and can be downloaded and used via the App Store (iPhone) and Google Play (Android).
“Rakuzumi” was developed to enable effective use of the Layout Navigator LN Series (LN-100 / LN-150 / LN-60 / LN-160)—widely known as “Kuinavi”—for building construction projects.
The software comes with functions tailored for construction work, such as grid line setup, position surveying, and building layout, allowing tasks to be performed easily, quickly, and by a single operator. Even users without professional surveying experience can operate the system with ease.
In addition, using “Rakuzumi” together with topographic surveying and positioning work helps digitize construction workflows. This not only reduces labor requirements and construction time, but also helps prevent construction errors and enables construction results to be recorded as digital data.
Today, the construction industry faces challenges such as labor shortages and an aging workforce, making it essential to transform traditional work methods.
“Rakuzumi” serves as a powerful on-site tool and represents a first step toward driving construction work into the digital era.
