Comparison on the construction and maintenance of flyover / Nor Hafizah Mohamad Nazri

In its most general sense, a flyover is a relationship roads or public way for the passage vehicles and people. Flyover is being as an important facility for people in terms of transportation and relationship between destinations. For that reason, the government plays an important role to reduce a problem on flyover. Before start a flyover construction, a research should be implement about a suitable construction method with the area either in terms of area or land structure. Nowadays many of flyover facing a problem from a structure aspect that can not sustain a load. This problem must to take a serious to ensure an incident not occur again. This dissertation will describe about a manufacturer that produce a flyover products or a parts of flyover component. In Malaysia, normally a contractor will select a material for a flyover either an in-situ concrete or precast concrete from a factory. It have a few precast product that always use by a contractor like precast segmental and precast beam. Precast beam is divide into certain type such as I, M and T type. A selection of precast concrete based on a site project. A data collection that are use is on the interview with a contractors, manufacturers, maintenance operators, client, and consultant. An observation also have been make at a factory and site project. From a research, a summary that obtained are a manufacturers have own method of flyover product Beside that, a contractor also have their own method for a flyover construction project and maintenance operator also using a method of maintenance works procedure. From the analysis that have been obtained, a conclusion that have been identify are, it have a differences among construction method of flyover product, construction method on site and maintenance method of highway from a manufacturers, contractors, and maintenance operators in Malaysia. Therefore in this study is extended to the comparison between cost, area, time, maintenance method and efficiency from cost versus time and manpower versus time. A result from this comparison are, it have a similarities and differences among that factors.
