Improved productivity using a modified table formwork system for high-rise building in Korea

Recently, construction of high-rise buildings in Korea has increased. However, the traditional formwork has disadvantages, such as low productivity, labour intensiveness, and long cycle times. Formwork is one of the largest cost components of a concrete buildingʹs structure, and is a factor with significant impact on construction duration. This paper proposes a modified table formwork system (MTFS) that can improve construction productivity, reduce labour requirements, accelerate construction schedules, and significantly reduce construction costs. A case study was performed to verify the validity of the MTFS by comparing schedules and costs of the MTFS with those of the traditional formwork system (TFS).
