Commercial mixed-use 22-story high-rise development comprising office space, hotel and parking structures.

Bethesda, Maryland, USA

The project required durable and efficient reinforcement solutions for topping slabs exposed to long-term environmental loading while maintaining fast construction schedules for a large-scale commercial development.

Design and implementation support for topping slabs reinforced with basalt fiber-reinforced polymer (BFRP) bars, including design in accordance with ACI 440 methodologies and coordination of material validation requirements. 

• Implementation of BFRP reinforcement in a 22-story mixed-use commercial tower
• Approximately 5,160 ft² of topping slabs reinforced with about 15,000 ft of BFRP reinforcement
• Improved installation efficiency due to lightweight reinforcement handling
• Reduced transportation and installation demands compared to conventional steel reinforcement
• Contribution to long-term durability and lower lifecycle environmental impact through corrosion-resistant reinforcement systems
