| Abstract: | Advanced technology is continuously being explored and developed to meet the needs of the modem competitive construction industry. As formwork is one of the core elements of reinforced concrete construction, selection of appropriate formwork system is very important and valuable. Due to enhanced environmental concern, increased resource costs, shorter cycle frequencies and demands for high quality concrete finishes, materials and formwork systems are progressively reviewed and upgraded to provide the optimum solution to satisfy the project specific requirements in a diverse construction industry. To review the current usage of formwork system in HK, details on twenty-five projects were collected, studied and reported in this dissertation. Traditional timber formwork, large panel steel formwork and handset aluminum formwork systems are three types of formwork system commonly used in Hong Kong. They are particularized in Chapter 2 of this paper. In the alternative to traditional timber and steel formwork, use of aluminium formwork in Hong Kong construction has significantly increased recently. In exploring the application potential of aluminium formwork system in depth, two particular case studies are considered. The practical aspects in association with the uses of the aluminium formwork system are also reviewed in Chapter 3 and Chapter 4. In Chapter 5, users' considerations in selecting an appropriate formwork system are collated from questionnaire surveys. Among those considerations, six factors, namely, cost of employing formwork system, construction speed, plant and crane usage, reusability and recycling of formwork materials, quality of finished concrete and safety are identified as the primary factors considered in the selection of a suitable formwork system. Chapter 6 establishes a solution model to identify the preferred system selection criteria by the construction decision-makers, based on the six primary factors described in Chapter 5. Inevitably, cost factor is the single dominant criteria in determining the formwork system to be used. Apart from the selection model, a cost model of formwork system is also constructed in Chapter 7 for comparing the overall cost of different types of formwork system. In addition to providing a better understanding of aluminium formwork application, this study provides assistance to project decision-makers in terms of selection factor consideration and overall cost benefits of aluminium formwork system as a system of choice. |
