Abstract
Some risk factors contribute to various adverse effects on project implementation, especially the construction project. Risk needs to be recognized by analyzing the relationship between frequency of risks occurrence and impacts that may arise regarding construction time completion. The superposition of frequency and impact will indicate the risk importance of various risk factors. This research, therefore, aimed to assess the risk importance in time aspects of construction implementation to the contractor as the project executor is associated with the project resource factors. The resource factors reviewed are related to construction labor, materials, and equipment. The object of the study observed is a large qualified contractor company in Aceh Province with experience in the construction field for more than 15 years. The selection of time constraints is linked to the conditions of the company under various situations in Aceh during this period, both during the period of political and military conflicts, in the postdisaster rehabilitation and reconstruction period, and in the post-rehabilitation and reconstruction period. Characteristics of contractors and risks emerging are observed from the results of questionnaires distributed as instrument of data collection. The three resource factors studied each consists of several risk variables. The use of variables in the questionnaire is determined from the test results related to the validity and reliability of these variables. Risk assessment results of the three factors in the research indicate that the frequency of events and the level of impact of each variable determine the magnitude of the risk importance value. The labor is a factor with higher frequency and intensity of impact than the other two factors of study. Therefore, these factors contribute significantly to the project’s completion time.
Highlights
Implementing the construction projects is vulnerable to risks that affect project objectives
It can be concluded that the risk is an occurrence of uncertainty with an absolute chance of a condition that leads to unfavorable consequences of project objectives
E selection of respondents is based on a contractor company that has been involved in construction work for the last more than 15 years. e number of companies involved in the questionnaire survey counted 15 companies out of a total population of 20 contracting companies with large qualifications. ese data are based on the membership of the company at the Construction Services Development Agency 2016. e minimum respondent is the personnel of Resources Variable factors code
Summary
Implementing the construction projects is vulnerable to risks that affect project objectives. Some internal or external risk factors may affect project targets. Risks are likely or no and, if they occur, will have an impact on the project [1,2,3,4,5]. Risks are the variable of activities or factors and, if they occur, will decrease the achievement level of project objectives, i.e., cost and performance [12,13,14,15]. It can be concluded that the risk is an occurrence of uncertainty with an absolute chance of a condition that leads to unfavorable consequences of project objectives. Risks in the project are a result in unfavorable physical, schedule, and financial consequences for the achievement of project objectives, i.e., cost, time, and project quality [12, 13]. Risks in the project are a result in unfavorable physical, schedule, and financial consequences for the achievement of project objectives, i.e., cost, time, and project quality [12, 13]. erefore, the risk is essential to manage risk project that can survive or perhaps optimize risk [12, 16,17,18]
