| Summary: | Nowadays, construction projects are becoming much more complex and difficult which include the bridge project. Thus, delay in project duration and overrun in project cost becomes a common occurrence which sometime the quality and safety aspect also been affected. Previous studies show that one of the contributing factors is the weaknesses of design produced by the designer. Meanwhile, buildability is the extent to which the design of a building facilitates ease of construction, subject to the overall requirements for the completed building. This study identified the problems occurred in one case study, Sungai Johor cable-stayed Bridge, that was conducted through site visit, interviews and questionnaire. Then, the problems were categorized into design related and non-design related problems. From the case study, it showed that the number of identified design related and non-design related problems are almost similar in form of number of occurrence. The case study also revealed that the impact of poor buildability is severe toward cost and duration ofproject, followed by quality. Other impacts which are less significant include safety and environment. This study has successfully established design phase buildability guideline for cable-stayed bridge construction. The guideline will help the construction people to ensure the implementation of buildability concept in their project and improve the project performance. |
