• Reduced damage on-site means less over-ordering and lower waste
• Lightweight construction = savings on subframes, transport, and labor
• Delivers long-term value without compromising design intent

• Civic buildings
• Educational campuses
• Healthcare facilities
• Transit and infrastructure projects
