Construction projects have a unique nature which takes the high risk due to many interrelated parameters. This study aims to investigate and assess the influence of the risk factors that occurred during the lifecycle of a school project which comprises the design phases, implementation and operation and maintenance. In addition to examining the effects of the internal and external risk factors that contributed by the school’s construction, in order to avoid the risk occurrence during the lifecycle of the projects. A questionnaire was prepared and distributed to a number of engineers in the Governmental Sectors (School buildings sector, Kirkuk Governorate sector, and Municipal sector in Kirkuk Government and Buildings sector in Erbil Governorate) in northern Iraq. The collected data which were analyzed using the relative importance index (RII) and matrix analysis to prioritize the project risks. The analysis results were revealed that the most significant risk factors in the school’s project lifecycle and construction were providing a proper water supply and storage system to maintain a continuous good quality of water, incompetent contractors and sub-contractors for completing school buildings, using proper construction materials to avoid cracks in the building, lack of safety in project site, keep the toilets clean to avoid diseases, and providing an emergency exits were considered the most significant risk factors in construction of school buildings.

The construction project is a complex sector which characterized with low productivity, cost and time overruns and conflicts. The major challenges in construction project risk assessment which may attributed to knowledge requirements for determining the level of uncertainty and development of complex models to predict . Portfolio theory and capital market theory stipulate that risk consists of two types, First, systematic risk, which cannot be controlled, emanates from external factors such as acts of God, natural disasters, market risk, interest-rate risk, and purchasing-power risk. Second, unsystematic risk, which can be controlled, relates to organization-specific factors such as business risk and financial risk (Fischer and Jordan 1996).) . To identifies the risk factors that influence the cost-effective management, operation, and maintenance of construction project, as well as how and when in the project life cycle the identified risk factors impact to the associated costs . The identification and design of risk is the first step of risk management. It contain the recognition of potential risk event conditions in a project and the clarification of risk responsibilities. A total of 50 risk factors on construction for stake holders (client , contractor ,consultant ) share projects were identified after conducting an extensive literature survey. A questionnaire survey was conducted from 60 project managers(20 from each category) in all three proficiencies with background experience in buildings ,road and bridges with minimum 15 years experience , to identify the most significant risk factors impact in construction projects . Interviews were conducted face to face, ensuring a 100 percent response rate. The questionnaire was amended by incorporating feedback of the experts to suit the local environments of the construction industry. The weight or rate of each risk factor gained by using a five-point Liker scale from a consolidated conceptual framework of all 50 risk factors identified from the deep literature work . The main aim of these research is to identify ,categorize and ranking common risks, exert management techniques to address those risks , effective risk management and risk status in the construction industry and to help stakeholders to take stock of their ongoing and future projects, with a focus on important risks, their management techniques and barriers to effective implementation of risk management systems.

Managing risk is an integral part of sound management and risk management helps to achieve projects objectives. Although the process of risk management is standardized to a great extent, risk control strategies depend on project circumstances and feature. One of the essential humanity’s challenges in the future, is surely ensuring water needs. Equitable and sustainable management of water resources is a major global challenge, and supply of clean fresh water is decreasing around all nations. Egypt is one of the countries hardest affected by climate change. Also challenges include population growth, increase in food demand and Lack of water and energy Leads to let managing risk for construction of water control structures projects on water streams in Egypt becomes more challenging and essential than ever before. Moreover, this study aims to show the effect of risk on cost and time targets for water control structure projects in Egypt .This study mainly identify a list of significant risk factors effecting on cost and time for these type of projects in Egypt through studying pervious publishing for risk management in construction projects and a questionnaire survey , then conducting a qualitative analysis using a Severity and Probability matrix (S/P matrix) techniques to assess the influence of risk factors and to isolate critical risk factors for a quantitative analysis. Finally, conducting a quantitative analysis by mean of Analytical Hierarchy Process (AHP) to determine the cost and time contingency, s the conclusion of this study shows that the cost contingency needed to account for the different critical risk factors is to increase the estimated cost by 12.35 % on the total estimated budget of the project. In addition that the time contingency needed to consider for different critical risk factors is to increase the scheduled time by 11.25% over the total originally scheduled of the project

Abstract Risk is involved in every construction project. Residential building construction projects comprise a variety of risks and are more likely to be affected due to their difficulty and many operations and threats. The study aims to identify the various risk elements and their effect on construction projects of residential buildings using a fuzzy approach with the help of MATLAB software. This study includes 60 risk factors recognised through an expert opinion and literature review. These factors are categorised into 7 major groups, i.e., construction, project manager, architect/consultant, contractor, owner, resources, and external environment-specific risk factors. A questionnaire was prepared and sent using emails based on the identified risk factors to be filled out by construction industry professionals in India and by conducting in-person interviews. Based on the risk severities obtained from the fuzzy model, the top 10 risk factors have been considered. As a result, for identified top severe risk factors, a significant risk response strategy was implemented.

Purpose This study aims to present the result of an assessment of the risk of construction digitalisation with a view to sensitising and preparing construction organisations for unforeseen issues that might arise in the course of their digital transformation. Design/methodology/approach The study took a post-positivist stance through a quantitative research approach. A survey of construction professionals actively involved in construction projects in South Africa was conducted using a structured questionnaire. The analysis of the data gathered was done using mean item scores, Kruskal–Wallis H test, exploratory factor analysis (EFA) and structural equation modelling (SEM). Findings EFA revealed five principal risk factors (human and financial, technological, legal and security, operations and socioeconomic risk factors) associated with the digitalisation of construction organisations. However, SEM revealed that four out of these risk components have significant direct relationships with some selected digitalisation outcomes. These significant risk factors are technology, legal and security issues, operations and socioeconomic issues. Originality/value This study provides practical insight into the risk inherent in construction digitalisation, and its result can help organisations seeking to be digitally transformed make informed decisions. Theoretically, the study reveals the risks associated with construction digitalisation – an aspect that has not gained significant attention in the current fourth industrial revolution discourse. Therefore, its findings can form a basis for future studies on the risk of digitalising construction organisations.

Delays in a construction project can be regarded as a failure. This paper aims to investigate the causes of delay in Indian construction projects undertaken by private, government and nongovernmental organizations. In view of this 45 causes of delay were identified and developed the questionnaire for the quantitative confirmation of the most causes of delay. Consequently the questionnaire was distributed to construction professionals like Managers, Engineers and others. Subsequently the collected data was analyzed using statistical tool and the factors were measured and ranked under each group by importance index for various construction professionals. The results suggest that delays are mainly due to shortage of labours, shortage of construction materials and extra works (rework and change orders). The resources like manpower and materials are having highest contribution of about 24% compared to other sources. However this paper presents recommendations for a better project management techniques & procedures which can be adopted during conceptual & detailed planning phases of the project in order to minimize the construction delay.

Financial Losses

Bridges are important infrastructures for urban growth and the economic development of a country, because bridges allow a large volume of logistics and transportation by connecting rivers, canyons, islands and lands. As such, massive resources including financial, material and human resources are invested for bridge construction and management. However, although the latest bridge construction is undergoing rapid development of new technologies and designs, the management and prevention of risks still tend to rely on qualitative practices, which, as a result, calls for more quantified and systematic measurement and, thus, more sustainable management of potential risks. As part of efforts in managing risks to achieve quantitative risk management, this study aimed to predict losses of financial resources by identifying statistically significant risk factors based on the past record of insurance claim payouts (compensation for a loss that occurred as a result of a material damage in bridge construction projects) from a major insurance company in Korea, and conducted a multiple regression analysis to identify the loss indicators and to develop a loss estimation model. The statistical analysis confirmed that superstructure types, superstructure construction methods, and construction duration are the three significant risk factors that affects financial losses of bridge construction projects among the seven variables adopted as independent variables, which included the superstructure type, maximum span length, superstructure construction method, foundation type, floods, typhoons, and construction duration. Such findings, and the consequentially developed risk prediction model of this study, will contribute to sustainable construction management through cost reduction by predicting and preventing the future financial loss factors of bridge construction.

In Ethiopia, the rapid expansion of the construction sector has resulted in the wastage of construction materials that negatively affect the environment, society, and the economy. The reason is inefficient waste management strategies practiced in construction projects. Hence, an adequate material waste management strategy is required. This study was an attempt to identify the key techniques that can help to minimize material wastage in building construction projects. Questionnaire surveys, interviews, and reviews of previous studies and related literature were employed in gathering the relevant data. Seventy of 85 questionnaires administered and distributed to contractors, consultants, and clients were returned. These data were analyzed using the relative importance index method. The results indicated that employing waste management officers for this purpose, using prefabricated or off-site production of components, appropriate on-site waste management, and incorporating a policy of material waste minimization plan were identified as key measures to minimize construction material wastes.
