An Analysis of Upper Structural System Work Cost Management Factors at Cimanuk Bridge Project at Majalengka, West Java

Abstract

The process of choosing the bridge structural materials has its own uniqueness. At Cimanuk Bridge project, the upper structure material selection is done using concrete material. However, steel structure is the main priority at the construction implementation on site. Furthermore, cost management should be taken into consideration in implementing upper structure work, especially if there is a change order. Construction and the development of infrastructure are fundamental to economic growth and societal advances.Unfortunately, project cost overrun and scope creep are common on infrastructure and construction projects. That is why this research does a systematic analysis to identify structural work costing indicators, specifically for the bridge project. The overall research problems are: analyzing the current condition of construction project budget implementation, identifying the bridge project work costing indicators, analyzing the upper structural system construction project budget using steel and concrete materials for Cimanuk Bridge. However, this research focuses in the process to analyze and identify the bridge structural project work costing indicators. This research uses the research methodology starting from the primary data collection, research findings review, and the recommendation which is expected to bring improvement needed by the project examined. Specifically this project is limited to before the analysis process. The method used is the quantitative method. Based on an analysis of upper structural system work costing management factors, it can be summarized that there are only 2 strong correlationfactor components which are structured in 7 independent variables are chosen at correlation test and inter-correlation test. Component factor 1 consists of X7 (ignoring the risk factor at the project location), X9 (ignoring the inflation and escalation factor), X10 (incomplete contract clause), X13 (too many working repetitions because of bad quality), X14 (the cost of material double order), X15 (the cost for worker wage), X31 (monitoring working performance to the expenses spent on the project). Component factor 2 consists of only X7.
