Abstract
Construction industry has been developing rapidly around the world. In Indonesia, the construction industry plays a significant role in the economic sectors. One of problems in construction management is construction waste. It has major impact on cost, time and quality of construction management. To reduce these negative impacts, it needs a comprehensive understanding on the cause factor of construction waste and management. The aim of the study is to examine the model of relationship between construction waste to cost and time that impacts quality of management project. The variable of construction waste was identified from interviews and site observation. Variable and Indicator of cost and time founded from Supply Chain Operations Reference (SCOR) Model approach. A survey was carried out through a structured questionnaire. The respondents are been experienced people in construction and management of building projects. In this earlier study, questionnaires were completed by 383 respondents. Data was analyzed with Structural Equation Model (SEM) with the aid of Analysis of Moment Structures (AMOS) statistical package. The results shown that the cause factor of construction waste has correlation by cost and time with path coefficient value of 0.54. Correlation of cost and time with path coefficient value is 0.51 with value of significantly 0.05. It has indirectly an impact on quality of construction management system. The finding will help construction practitioners to reduce construction waste and gives better understanding to improve construction management sustainability.
