Abstract

The purpose of this study was to efficiently use wood to support concrete casting and ceiling frames, to find out the cost efficiency of implementing two different types of formwork systems, between conventional wood formwork by reusing post-casting scaffold wood for ceiling frame materials, with semi-modern formwork systems. Formwork (Scaffolding) and hollow metal ceiling frame systems. The data collection method in this study was carried out by observing the process of building an office building in JABODETABEK on conventional Formwork, wooden Scaffolding and semi-modern Formwork, interviews, questionnaires on the efficiency of field implementation, and documentation. Tests to compare the two scaffolding formwork systems were carried out in one-story buildings to four-story buildings with a typical floor area of one to a specific four-floor floor area with the same area to compare and measure the two scaffold formwork systems. At the time of project implementation on conventional formwork scaffolding, there is a loss of wood volume of ±40% of the total wood use. Overall calculated from the test results of these two systems in terms of casting costs, it turns out that conventional formwork with wood scaffold formwork system is much better and more efficient, saves implementation time, saves implementation costs, the difference between the two systems on wood is calculated using SNI 7394:2008, ranging from ±122.7 % to ±146.2 % wood is more efficient than the formwork system (Scaffolding). Then in terms of efficiency, the volume of post-casting scaffolding wood, of ±60%, can also be reused more than enough to meet the needs of the ceiling frame material for the high-rise building itself, which means that there is no need to buy new ceiling frame materials. Meanwhile, the semi-modern formwork system for the ceiling frame needs to spend more on buying ceiling frame materials such as hollow iron. Comparing the test results of these two scaffold formwork systems for simple high-rise buildings and low-rise buildings (onestory buildings to four-story buildings) is recommended to use a conventional formwork system, namely the wooden scaffolding formwork system.
