A STUDY ON THE TIME MANAGEMENT METHOD UTILISING NETWORK ANALYSIS TECHNIQUE

Abstract

 Construction works are exposed to the external environment. Therefore it is impossible to maintain the schedule planned originally due to the sudden weather changes, traffic conditions, and many un-known factors. Site manager usually monitor the progress of works, quality required, safety condition, and construction cost fluctuation based on his experiences.
 Critical Path Method (CPM) based on time-related connection is fundamentally good for the detecting and monitoring of schedule control. There are many computer soft wares available for us to find critical path easily, even on complicated construction program. However there is some special feature in construction works, such as construction resources required continuous or time-interval re-mobilization. On the other words, even time would be flowed, resources would be there. As a result, non-critical path construction items might affect critical path flow, we believe theses items have high risk potential due to schedule changes.
 In this paper, we study on the detection method of high risk potential items utilizing Between-ness centrality of Graph Theory for network model including resources' relationship. Finally we verify the effectiveness of our proposed method applied on an in-situ continuous post-tension method box-typed bridge construction works carried out in oversea country.
