The workflow

Three steps. No spreadsheets, no estimator backlog.

The assistant does the quantity take-off that normally takes an estimator days. You review and send to site.

KOS reads the geometry

It detects walls, junctions and openings, then maps the Kalzen panel grid onto your plan — the way an application engineer would.

Precast capacity

Cast off-site. Assembled on-site.

The Kalzen system uses precast concrete panels manufactured in a controlled factory environment. Panels arrive on-site ready to assemble — reducing wet work, formwork, and construction timelines by up to 50%.

Panel grid mapping
Every wall gets the right panel — automatically sized and indexed.
Junction detection
T-junctions, L-corners, and cross intersections — counted and typed.
Cost estimation
Six-table BOQ with unit rates, totals, and formwork accessories.
