| Summary: | High-rise buildings are commonly built in densely populated countries or urban areas. A balanced floor construction cycle is critical for construction of the frame structures. The objectives in scheduling the floor cycle are to ensure smooth flows of resources and to optimise the use of formwork and other materials. The floor area is usually divided into zones to allow the labour force and formwork materials moving between zones. The preparation of the floor construction cycle would therefore be a resources allocation exercise. However, the process is complex and difficult when it is done manually. Floats are created deliberately in the schedule to ensure the balance in resources and to provide buffers. Simulation that can demonstrate the real world operations is an effective tool in handling this scheduling problem. This paper examines the constraints in planning the floor cycle and the effects of working period on the overall schedule. Network based simulation model is used to investigate the problems. It is noted that variations in working periods have significant impacts on the time schedule. A saving of 37.2% in time could be achieved when the working period is extended by 20%. The findings indicate that simulation can be used to assist planners to improve their decisions and decide the strategies in scheduling and reviewing the floor construction schedule. |
