Abstract

Hospital building construction requires efficiency in cost and time without compromising structural safety and reliability, particularly in floor slab elements as part of the project’s critical path. Conventional cast-in-situ methods often face challenges such as extensive formwork, temporary scaffolding, weather dependency, and intensive labor coordination. This study aims to evaluate cost efficiency, construction time, labor requirements, ease of installation, and structural performance by comparing cast-in-situ and precast half slab methods using the Value Engineering Job Plan approach. The results indicate that the precast half slab method can reduce construction costs by 39.8%, equivalent to approximately IDR 403.9 million per floor, through the elimination of permanent formwork, reduction in reinforcement volume, and optimization of concrete usage. In addition, the construction duration is accelerated by up to 40% (15 days compared to 25 days) due to controlled factory production that minimizes dependency on site conditions. Structurally, the composite system of precast panels and concrete topping meets requirements for flexural strength, diaphragm stiffness, and complies with SNI 1726:2019 standards. This study concludes that the precast half slab method is more efficient and suitable for hospital construction projects, provided that strict quality control is maintained in panel production, connections, and on-site implementation
