| Abstract |
The reduction of construction duration and cost is two of main success factors in the modern construction industry. Since reinforced concrete is the most economical material for construction, the large-scale form-work of concrete is also related to the competitiveness of construction method. Thus, the application of appropriate form-work system is one of key factors to reduce the construction cost, improve the quality of the finished concrete, shorten the construction period, and reduce the form-work collapse during the construction. The study conducted the case study to identify the cost differences between the steel-wire truss deck system and the table system form-work system. To compare the construction cost of two different form-work methods, the study estimated the total price for the form-work module of 14.4m×4.8m with material quantities. This study identified that the slab cost of truss deck form-work system was 15% lower than the table system form-work even though the combination form-work cost of beam and slab for the truss desk was 19% higher than the combination form-work costs of system form-work. In addition, the study identified that the truss-deck form-work system also required the additional steel reinforcement of 77% compared to the table system form-work. Finally, the study concluded that the table system form-work could reduce the total construction costs of 15% through lowering the form-work cost of beam and slab, and steel reinforcement. |
