How much faster is the AI app than the traditional method?

The app reduces quantity takeoff from a maximum of 12 hours to 10 minutes. It also cuts total man-hours from up to 15 hours to 4 hours.

Who can use this AI app?

It is offered first to companies engaged in quantity takeoff and ordering in the construction and building industries. Even staff with no specialized skills can create a material list using the app.

What does the AI app do with a blueprint?

Users upload a PDF of a design blueprint, and the AI extracts the dimensions, materials, and quantities of the building. It can then generate a list—such as 8 instant noodles or 10 fence meters—and export it as Excel.

3 Key Points

What happened
renue and Marubeni Construction Material Lease launched a quantity takeoff app in August 2026 that reads blueprints to extract dimensions and materials, cutting a task that took up to 12 hours to 10 minutes.
Why it matters
The app is rolling out first to companies handling quantity takeoff and ordering, and users do not need specialized skills to create that material list—removing a bottleneck in construction workflows.
What to watch
Marubeni and renue started a joint project in August 2025, and the rollout for this AI-era role model will depend on whether more construction and building firms adopt the app.

WHO IT HITSConstruction firms and building-material companies that handle quantity takeoff and ordering, especially those with fewer experienced estimators, are the main users targeted by this app.

Context & Analysis

Quantity takeoff is a manual process in which workers read dimensions, materials, and quantities from design blueprints, calculate them, and compile totals. At Marubeni Construction Material Lease, 5 to 6 full-time employees handled this work, and each construction project took 2 to 15 hours. Reading blueprints requires experience-based know-how, so assigning the task to new employees was difficult. The new app lets users upload a design blueprint as a PDF, and the AI extracts the dimensions, materials, and quantities of the building. For a 2D drawing, it generates a list such as 8 instant noodles or 10 fence meters and outputs it as Excel—the example list is illustrative of the output format.
