Applying scaffold in outdoor construction is the common practice to the traditional construction In temporary construction, due to its convenience and low cost, tubular steel scaffold is popular and most frequently used. However, in order to manage the altitude of buildings, constructors climb and transport construction material in heights. In that less safety condition, it is often to see tragedy caused from schedule scaffold collapsing, or falling. These accidents not only delay the construction, but also increase the constructal cost Although the government has established regulations in traditional scaffold construction, it is still not complete yet; scaffold construction is still threatening the life of constructors and the companies. On the other hand, it’s space and structure, scaffold work does not support the capability for placing materials. Swing machine becomes the only solution to transport the construction materials, while it is very dangerous and cost a lot.
In 1998, mast climbing work platform was introduced to Taiwan from Holland to replace the scaffold work. The mast climbing work platform provides a false work method which includes an area to lay up the material and work. The Vertical construction replaced the Horizontal construction; each overlapping work becomes the critical path and reforms the traditional methods. In Taiwan, the work was initiated used at chimney, indoor construction in tall building, and also introduced to the outdoor construction.
This research, focuses on the comparison of the mast climbing work platform usage and compare to the Scaffold work. There are several cases would be analyzed by the following issues 1. construction efficiency, 2. construction cost, 3. safety, 4. pollution affection. This report suggests that the safty and the effectiveness are the key factors improve the construction, it suggests the followings:
1.Use the new machine to improve the construction techniques, to simplify the operation and construction, to automate the original human work, and to standardize the regulations. The regulations will be adjusted according to different machine usages. For example, the work platform was used often in outdoor construction, a comprehensive working plan must be provided.
2.The traditional scaffold work won’t necessary to be replaced when there are new techniques or machines being introduced. Although the traditional scaffold work has lower safety, it still provides a higher work flexibility and work efficiency in lower building. To broadly introduce the mast climbing work platform represents a new trend in falsework construction. In this report, there are real cases to prove the theory, and provide the managers in construction management.
3.The main purpose in the research is, under the condition of the constructed building is higher than 30 meters, each work section is larger than 20% of the entire work, the total work types is less than three, all the work section could overlap each other and is less than 30% of total construction time, the mast climbing work platform should be provided. The mast climbing work platform is able to perform within two or more carriages to increase parallel work. How to perform the two carriages in a more efficiency way is part of the major issue in construction.
4.In order to help the growth of the working platform technique, the government should provide comprehensive regulations to improve the safety of the construction environment.
