Identification and assessment of risk factors affecting construction projects

HBRC Journal, 2015

Cost saving and time performance are usually essential to all parties who are involved in a construction project, that is owner, contractor, subcontractor. The main causes of disputes in construction projects involve delay and failure to complete the work in the specified cost and time frame. The delivery time of a project is a key factor to the owner in terms of cost as much as it is for the contractor. Unexpected increase in cost and delays in construction projects are caused by owner, contractor, environments, etc. in which several types of risk factors may occur concurrently. The effect of cost overrun and schedule overrun do not only influence the construction industry but the overall economy as well. Even though construction project increasing in cost and schedule has received extensive attention of researchers, but because of continuous changes and development in the field, the study considered of added value to the construction industry in Egypt, in addition to risk strategy and plan analysis. In order to meet the deadline of a project and due to the complex nature of construction projects, cost and scheduling should be flexible enough to accommodate changes without negatively affecting the overall project cost and duration. As such, the objectives of the presented research in this paper are to identify, study, and assess the effect of the factors that affect cost and time contingency. Data are collected from sixteen construction companies in Egypt. The collected * Corresponding author. Cell: +20 100 50 175 30.

Quantifying Delay Risk Potential of Road Projects during Construction Phase: A Case Study

MATEC Web of Conferences, 2019

A comprehensive plan is required to anticipate risks in a construction project. In practice, however, anticipated or unanticipated risks may eventually lead to delays in the project completion date. The aim of this research is to quantify the delay risk potential of a road project during the construction phase. A project at Batang-Kendal road has carried out thorough planning for all required aspects. However, in the implementation of a project, there is often the occurrence of irregular events, which act as a case study for this research, from which delays were identified, observations mapped and semi-structured interviews conducted with project stakeholders, i.e. owner, contractors and supervisory consultants. An instrument was developed to assess and quantify the project risks identified using a 1 to 5 Likert scale. The results showed nine types of delay risks and 32 sub risks. The quantification of these risks was classified into four risk levels, i.e. extreme (6.25%), high (53....

A Study on Risk Factors Involved in theConstruction Projects

International Journal of Innovative Research in Science, Engineering and Technology, 2016

Infrastructure development is the key of success to any country in present scenario. It will generate a large number of jobs and increase in growth of economy as well. Therefore the projects involved in infrastructure development have to invest a huge amount of money. In consideration of the same if any kind of wastage of resources takes place that will result in huge momentary losses. These losses are due to various types of risks associated with such development projects. A crucial role is played by these risks for the completion of project successfully with in the time schedule and allotted budget. This study primarily discusses the critical risk factors and its evaluation techniques by conducting a comparative study of various international and national construction projects. About 50 articles published over the last 15 years were reviewed. The finding was that a simple analytical tool will be developed for each project task to evaluate the risk quickly and effectively to do the...

Risk Analysis of Delay in The Construction Project

Neutron

The complex problems that existed during the Field Implementation in the SMP Negeri 1 Surabaya project at that time caused some work that was not as planned both in terms of time, quality and cost which resulted in overbudget and overtime. When experiencing overbudget and overtime, it is necessary to have good cost, quality and time management. Good management should not only be owned by the project owner. The length of time to complete the project has a big effect on the increase in the overall project cost. Therefore, daily, weekly and monthly progress reports are needed to report work results and completion times for each project work item. Furthermore, this work is compared with the completion time of the plan so that the completion time can be controlled for each period. This is because the construction of the building has a delay in time so that it can cause disruption in some field operations. The analysis that I have done is viewed from all of them (owner and contractor). Th...

RISK MANAGEMENT IN INFRASTRUCTURE PROJECT

Risk identification and analysis for complex mega infrastructure projects has become one of the main parts of the present-day project management process. In this paper, we discuss few methods of measurement of project risk, such as probabilistic analysis, risk severity analysis and risk matrix method for the complex project such as Ahmedabad metro. The methodology used in this paper are primary data collection, where the major risk activities of metro rail infrastructure project were known through interactions with experts and questionnaire surveys. The identified risks were analyzed for likelihood, impact, severity of a project. This paper aims to compare different results found through the different type of qualitative as well as quantitative analysis methods and to know the common high rated risk factors.

Risk Factors Affecting Public Infrastructure Projects

Risk Management in Construction - Recent Advances [Working Title]

The delivery of public infrastructure projects in South Africa is bedevilled with many challenges leading to project delays and loss of needed public resources. This study, therefore, sought to identify the risk factors affecting project delivery and the sources of these risk factors. This study employs a qualitative research methodology. To gather the required data, open-ended interview questions were administered to the participants from the various provincial departments in the Northern Cape responsible for delivering public infrastructure construction projects. A purposive sampling technique was used to select the relevant participants to form part of the study. The data collected were analysed using qualitative content analysis. The underpinning factors for these risks affecting project execution are classified as internally and externally generated. The identified risk factors pose a significant threat to project delivery leading to delay and loss of public funds and adequate ...

Risk and its impacts on time and cost in construction projects

Journal of Project Management, 2020

The construction process is inherently prone to risks. Risk management is an essential and integral part of project management on all construction projects. Risk analysis is one of the core components of risk management that enables professionals to quantify and analyze risks that may pose potential threats to project performance in terms of various parameters. This research was conducted to identify and analyze risks associated with residential construction in Bangalore. In this study, risk and its impact on time and cost was identified and analyzed. Schedule impacts of project risks were supplemented by conducting quantitative risk analysis such as Monte Carlo simulation and sensitivity analysis using the Primavera risk analysis software. In case of cost, the cost variance was found out and mitigation measures were given. Thus, by effectively managing the risks, organization has more timely, comprehensive and deeper understanding of risks which in turn facilitates better decision making and confidence to take on new ventures or even to accept higher level of risk.

Risk Factors Causing Delay of Urban Infrastructures Projects, Nepal

The infrastructure construction sectors are usually complex. Zero risk construction projects are only an assumption. The objective of this paper is to identify the risks factor associated with the urban infrastructure construction projects causing delay. The research found that those risks are directly associated to clients, contractors, subcontractors that would cause delay in the construction work. Other factors are also identified such as project, financial, political, technical, market risk, managerial, resource risk, and force majeure. All risk factors affect the time, cost and quality performance of the construction project. From risk management perspective, it is the process on which identifies the risks and analyzed with qualitatively and quantitatively. All associated risks can treat by various mitigation processes and then mitigating method are monitored to control the risks. Risk management distinguishes between success and failure of a project. So, Nepal could use it effectively to meet its growing need of infrastructure and job opportunity.

An Assessment of Risk Management Factors Delaying Construction Project in Nigeria

CERN European Organization for Nuclear Research - Zenodo, 2022

Risk management is a field that exists within the subject area of project management deals with the identification, monitoring and mitigation of risks. It is seen as the effect of uncertainty on objectives so this process serves as an optimization of the project delivery process to ensure that the project objectives are achieved. Risk results from a variety of factors like design problems, technological complexity and lack of experienced personnel. Managing these risks involves contemplating actions or measures. The study aimed at assessing risk management factors delaying construction project in Nigeria. The objectives were to examine the factors that influence the development of risk management in the construction industry and identify the level of knowledge, experience and barrier to risk management practice. The research approach adopted for this study was quantitative design. To cover the study area effectively, a field survey was utilized inform of a structured questionnaires for the major study population and anchored with semi-structured interviews for the secondary population and other relevant secondary data. 70 Professional Project Managers were sampled from different construction firm. Hence, 70 questionnaires were administered while 40 questionnaires were properly filled and returned for collation represents 57.1% response rate. Statistical tools was used for the study. The result confirms showed that Change in climactic condition is the major factor that influences the development of risk management in Nigerian construction industry. Result also suggests that majority of the respondents upheld the relevance of risk management practice in project management. The implication is that most though Professional Project Managers understood the relevance of risk management in the construction industry, they should always make provisions for uncertainties through effective risk management strategies.
