| dc.description.abstract | Formwork is one of the most resource intensive components in reinforced concrete
construction, often contributing significantly to both project cost and duration. The efficiency of a
construction project is therefore closely related to the selection of an appropriate formwork
system. As formwork plays a critical role in determining the timeline and budget of construction
projects, selecting the appropriate method is essential for project optimization. This study aims to
compare the cost and time efficiency of aluminium formwork and semi-system formwork in wall
construction. The research is based on a case study of the RSS Building at the MRT Jakarta
Station, Central Jakarta.
The methodology involves a comparative quantitative approach using both primary data
from field observations and interviews, as well as secondary data from project documentation and
prior studies. Cost calculations include production, installation, and rental components, while time
efficiency is measured through man-day analysis. Labour productivity coefficients, especially for
aluminium formwork, were adopted from existing research to ensure accurate and standardized
comparison.
The results indicate that aluminium formwork offers greater efficiency, with a total cost
of Rp 591,678,031.53 compared to Rp 976,997,040.88 for semi-system formwork. Additionally,
aluminium formwork demonstrates better performance in reducing execution time due to its
modularity and reusability. Therefore, aluminium formwork is recommended for large-scale
projects and should be considered in future construction planning and national standards. | en_US |
