“…In the opportunity theory, the risk is the probability of unexpected conditions and all of consequences possibility for project delays or project failures [6][7][8][9][10][11]. 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]. From the above definition, 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.…”

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.

“…Based on Goh & Abdul-Rahman (2013) findings, the construction stage was found as the project stage with higher frequency of risks due to involvement of many investments and longer completion period. Based on research done by Mahamid (2011) andAl-Najjar &Janura (2008), it can be concluded that most likely both building construction and highway construction project has similar factors of risk that contribute to the cost overrun and time delay. Research done by Wang, Dulaimi, & Yousuf, (2013) concluded that risks associated with infrastructure projects in Malaysia which focused on highway projects are under the following categories: i) Political risks: Government support is the main and important factor which contributes to the ease of the construction of highway in Malaysia.…”

The construction of highway projects involves many types of risks throughout the various stages of itsproject life cycle. Those risks are especially significant due to their impact on the project performance and objectives, mainly in terms of costs and time. Several factors of projects risk had been determined and well explained in the paper. Major risks involved in highway construction in Malaysia are cost risk, safety risk and time risk. Due to lack of opinion from the contractors regarding the critical factors that influencing the project risks mentioned, this studyaims to evaluate the contractor’s perspective towards the important factors of risk particularly the cost and time risks in highway construction in Malaysia. The methodology used in this study is by using quantitative method.Questionnaire survey was developed by taking into consideration the factors influencing the cost risk and time risk that had been explained in the literature. The respondents were chosen by purposive sampling which enables the researcher to collect the data comprehensively. Results from this study confirmed that the construction risks and financial risks are most often occurred in highway projects. This research identifies potential factors influencing both cost and time risks that have a possibility to occur in highway projectsin Malaysia from the perspective of contractors. Among the key findings of the factors that highly influenced the cost risks in the highway projects in Malaysia include service relocation, removal and replacement of material,design changes, additional works, environmental issues, and price fluctuation. On the other hand, the main factors influencing time risks which mostly related to time overrun/delay are permit approval, weather condition, low workers’ productivity, slow preparation and drawings approval, design changes and error, and shortage of worker. This study contributes to the current body of knowledge by providing researchers and practitioners with a set of important factors related to time and cost risks that need to be consider in improving the performance of highway projects. It is hoped that this study would help the industry to promote project success of highway projects in Malaysia.

“…In recent decades, plenty of risk analysis methods have appeared in the construction industry. Risk matrix (RM) (Mahamid, 2011), Monte Carlo simulation (MCS) (Mejdoub and Ben Arab, 2018), fault-tree analysis (FTA) and FMEA (Liu et al , 2015; Panchal et al , 2018) have all been used to identify and decrease risk events in the construction industry. An RM uses a qualitative analysis of components to rank risk events, classifying quality risks into a limited number of categories (Ahmadi et al , 2017).…”

Purpose The purpose of this paper is to mine information on the construction process of previous projects to develop a construction plan that meets both quality requirements and schedule constraints. Design/methodology/approach This paper uses a failure mode and effect analysis to evaluate the construction quality of 311 apartments in Shanghai. The authors also evaluate construction-scheduling control using the earned value management technique and implement an artificial neural network to correlate the results. The authors then develop a quality risk and schedule correlation model based on Big Data. The model can predict the relationship between the planned schedule and the project quality risk using multiple variables such as the number of layers, the schedule performance index and budget costs. Findings The methodology offers an innovative approach for assessment on the relationship between quality risk and project schedule. The authors have also built a multiple regression analysis model for comparative purposes with the model. The results show that the proposed model can better describe the relationship. The model can provide a quantitative quality risk value that changes with the planned schedule, as well as help project managers to understand the relationship between quality risk and project scheduling more accurately. Research limitations/implications The research approach only focuses on quality risk under the impact of scheduling. Future efforts might focus on developing a model that connects failure models with project schedules and costs in order to improve the effort of quality management. Practical implications The model based on Big Data in this paper is developed using real projects and reflects the relationship between project quality risk and scheduling in real environments. The created application provides support for project managers to develop and adjust quality plans and schedules, thereby reducing deviations in quality and scheduling objectives. Originality/value The authors make full use of historical project data from the perspective of both quality and schedule management, and provide a novel method to intelligently and objectively analyze the relationship between quality risk and scheduling.
