Economic performance and construction productivity play decisive roles in the adoption of innovative structural technologies. This study presents a comparative cost and productivity assessment of Bubble Deck slabs and conventional reinforced concrete (RCC) slabs. Using analytical data for a 2100 ft², 150 mm slab, the study evaluates parameters such as material costs, labor efficiency, equipment utilization, and life-cycle cost (LCC). Findings reveal a 3.6% direct cost advantage, 30% material savings, 33% reduction in construction time, and improved environmental performance over a 100-year service period. The discounted life-cycle cost analysis shows sustained economic benefit, reinforcing Bubble Deck slabs as a technically and financially superior option for sustainable infrastructure
