Therefore, a research is required to explain ranking factor that causes project delay and ends up in construction claims for extension of time and additional cost, so that the employer can approve. Research data is obtained by using interview and opinion survey to respondents through distribution of questionnaire among competent stakeholders. The research method used for data processing is descriptive statistical method in which the validity and reliability test are done using SPSS 24. KMO Measure of Sampling is used for comparing the range between correlation coefficient and partial correlation coefficient. The Principal Components Analysis method is used for factors extraction. The collective of respondents’ opinion data tabulation, and analysis result in the ranking of factors in project delay. The top factors are those that cause the claims for extension of time and additional cost are accepted by the employer. The ranking becomes consideration for employers to take the next steps in determining attitude toward the extension of time and additional cost claims. Among 24 incidents or events that cause project delay, the top 5 rankings are; 1) absence of contractor’s work performance progress evaluation, 2) design change, 3) low bid price ratio, 4) inconsistence of payment term with the contract, and 5) late drawings submission. Those five causative factors, based on the analysis result, can represent this whole research results. Therefore, the contractors’ claims for extension of time and additional cost caused by any of those five factors, are supposedly accepted by the employer.

INTRODUCTION Construction execution is an action to build designed construction. A construction work can be evaluated as good or bad based on the resulting cost, quality, and time. Project performance is a way to determine how a project works by comparing actual work result with how the project is planned in the contract that has been agreed between the employer and the service provider or contractor. Construction project performance is highly affected by risk factors that attached in every construction project stage. Risk factors are uncertainties. However, in the field, there happens to be numbers of problem that cause disputes between contractor and employer, mainly in water building projects under the scope of Banten Province Government. The claims for extension of time and additional cost is one of the demands from contractor that naturally cannot always be granted by the employer, and as the result, the employer experiences difficulties in taking technical decisions, even though they have been accompanied by supervising consultant. Based on the explanation above, it is required to formulate the problems of factors that cause project delay and the dominant causative factors that are not the contractor’s doing. This research uses two types of data, primary and secondary. Primary data is obtained from respondents’ questionnaire answers, while secondary data is used directly from the source without being processed. The data can be literal study such as books, journals, papers, work order letter, or previous studies, The respondents for this study include Heads of Work Unit, Commitment-making Official, and Technical Executive Officer of the Activity from the user. Then, planning consultant, supervising consultant, and executing contractor from the service provider of projects in Banten Province. The independent variables of this study are events that cause project delay that can become the base to propose claims for extension of time and additional cost. Meanwhile, the dependent variables are decision that will be made by the employer based on the result of the quality and ranking of respondents’ opinion toward the independent variables. The result of respondents’ opinion data collecting, tabulation, and analysis, results in ranking of causative factor of project RESEARCH ARTICLE OPEN ACCESS
