Risk Assessment of Resources Factor in Affecting Project Time

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.

Implementing Fuzzy TOPSIS on Project Risk Variable Ranking

“…e variables are lack of labour, unskilled labour, undisciplined labour, and low productivity of labour. e dominant factor is in line with Husin's previous research, which only examines the project objective of time [9]. We stated that integrating all three criteria of cost, time, and quality simultaneously is more logic to analyze risk variable ranking.…”

Relative Importance of Risks in Hydropower Projects and Project Finance in Nepal

“…Hossen et.al., (2015) used AHP to analyse severity of risk and frequency of occurrence of risk by RII method in their study of construction delay risk in international nuclear power plant. Husin et al, (2018) used Frequency Index (FI) and Severity Index (SI) similar to RII and AHP in their study of risk assessment of resource factor in affecting project time. Muneeswaran et al, (2020) in their study of schedule delay and risks in Indian construction industry also used RII method.…”
