CSI SAFE

Pricing. Plans start at $1,144.50. See full pricing · Updated November 10, 2026

CSI SAFE is floor, foundation, and post-tensioned slab design software with integrated modeling, design strips, and tendon editing, priced in US dollars on csiamerica.com/sales.

SAFE focuses on elevated slabs, mat foundations, and post-tensioned floors where soil–structure interaction and tendon layout matter. CSI's product page describes a model explorer, soil-supported foundations with uplift checks, and design strips for reinforcement.

CSI publishes SAFE perpetual licenses on csiamerica.com/sales: Standard US$5,952 (maintenance US$1,041/yr) and Post-Tensioning US$8,928 (maintenance US$1,561/yr), plus a three-month Post-Tensioning lease at US$1,144.50 including maintenance for the lease term (verified 10 November 2026). All figures are USD.

Do not confuse SAFE with FME by Safe Software, a separate data integration product. SAFE runs on 64-bit Windows 10 or 11 per CSI system requirements.
