“…The project level includes the direct and indirect costs of the project, and the regional level includes the impact of the MIP on the local economy. During the construction and operational phase of the MIP, many risk factors—such as construction and installation cost overruns (ECRF1), construction delays (ECRF2), poor project quality (ECRF3), and operational and maintenance cost overruns (ECRF4) [ 65 ]—affect the direct cost (EC1) and directly lead to project budget overruns. The high indirect costs (EC2) of a project are mainly related to construction waste disposal cost overruns (ECRF5), land acquisition and relocation of migrants’ cost overruns (ECRF6), and ecosystem restoration cost overruns (ECRF7) [ 27 ], which further increase public and government expenditure on the MIP.…”

Mega infrastructure projects (MIPs) have become increasingly important to the realization of sustainable development in China. Sustainable development is a process of dynamic balance, and coordinating the triple bottom line (the environmental, social, and economic dimensions) will enable more sustainable development of MIPs. However, previous studies have lacked consideration of coordination when applying sustainable development principles to the systematic identification of risks to MIPs. The goals of this study were to clarify the definition and dimensions of the sustainable development of MIPs and to identify the key risks of MIPs. A literature review was performed to extend the definition of sustainable development of MIPs by combining the triple bottom line with a fourth coordination dimension. A conceptual model of MIP risk identification was then proposed from an extended sustainable development perspective, 22 sustainability elements and 75 risk factors were identified, and the key risk factors were determined based on the interview responses and fuzzy set theory. The results show that economic risks have a high probability, social risks have a high loss, environmental risks have an intermediate probability and loss, and coordination risks have the greatest impact. In addition, the three most important key risk factors were found to be construction and installation cost overruns, land acquisition and resettling cost overruns, and information sharing with the public. Identifying key risk factors can provide information to help stakeholders understand the risk factors associated with MIPs and formulate reasonable risk response strategies.

“…Therefore, it is important to cooperate with experienced stakeholders as their experience achieved from previous projects may help to prevent possible errors (Tijanić et al, 2020). According to Pilger et al (2020), many errors result from geological, geotechnical and soil quality studies.…”

This paper deals with an analysis of causes that lead to the change in price (value of construction costs) of road infrastructure projects in selected phases of the building structure life-cycle, more specifically procurement and construction phases, with the aim to refine the price estimation in the Estimated Value determination phase. The sample of regional road construction projects in the South Moravian Region (Czech Republic) documentation forms the basis for the research. The methodological procedure is aimed at monitoring changes in the value of construction costs during the preparation and implementation phase of the construction. Estimated values, contract prices and actual prices of individual projects are compared to determine them and the reasons for their differences are discussed. The changes (decrease) in the values of construction costs determined by estimated value and contract price show the strong influence of the construction market and the interest of construction companies in the implementation of public works contracts in the field of road infrastructure projects. The relative differences range up to 47%. The changes (increase) in construction costs determined by contract price and actual price are much lower, up to 13%, and result from specific situations during the implementation of the construction, for which subsoil bearing capacity problems and material changes were determined as the most significant.

“…The construction industry contributes a valuable amount to the economy of any country, however, it is still badly affected by several issues such as cost overrun [ 1 , 2 ], time overrun [ 3 , 4 , 5 ], price fluctuation due to inflation [ 6 , 7 , 8 ], and most importantly due to poor safety performance [ 9 ]. Despite these severe issues, a project gets completed, but is not declared successful because the project failed to achieve the projects’ objectives [ 10 , 11 ].…”

Infrastructure projects are the foundation for essential public services and have an influential position in societal development. Although the role of infrastructure projects is substantial, they can involve complexities and safety issues that lead to an unsafe environment, and which impacts the project key stakeholders. Therefore, this study aimed to evaluate the barriers to implementing occupational safety in infrastructure projects in the Gaza Strip, which cause serious threats and reduce project performance. To evaluate the barriers, 39 items were highlighted and modified as per the construction context and environment, and which later were distributed in the form of a questionnaire, to get feedback from consultants and contractors. The analysis shows that in the safety policy barriers group, consultants and contractors both ranked the item “a contractor committed to an occupational safety program is not rewarded” first. In the management barriers group, consultants and contractors both ranked the item “safety engineer does not have significant powers, such as stopping work when needed” in the first place. In the behavior and culture barriers group, consultants and contractors both ranked the item “workers who are not committed to occupational safety are not excluded” in the first place. Overall, both consultants and contractors shared the same viewpoint in classifying the barriers in the working environment. The outcome of this study is beneficial for Palestinian construction industry policymakers, so they can monitor the highlighted barriers in on-going infrastructure projects and can modify the safety guidelines accordingly.
