“…As shown in Figure 1, EPC projects allow the client to have a single contact point and fewer responsibilities and enable contractors to execute projects with greater control and flexibility [18]. EPC models have become favoured for infrastructure project clients in the international market [19] and are commonly used in Australia, China, India, Europe, the Middle East and Latin America [20]. These countries and regions quickly developed significant infrastructure during the past three decades [21].…”

A Study of Design Change Management for Infrastructure Development Projects in New Zealand

et al. 2022

Design changes seem to be an inevitable part of engineering, procurement and construction EPC projects. Such changes create a need for a proactive approach to adjusting project scope, cost and time (the triple constraints) for efficiency and effectiveness in overall delivery. This study investigates the causes and implications of design changes in order to improve design change management practices. Data for the study were obtained through online interviews with New Zealand industry practitioners. Thematic analysis was used to collate the results into meaningful data. The study found that design changes were predominantly caused by clients’ inadequate strategic planning, insufficient attention to design, EPC contractors’ inadequate design ability, and on-site variations. There were three categories of such design changes: direct impact on the project, the reciprocal and complementary effect on stakeholders, and the far-reaching impact on the community. The study concludes by suggesting improvements, such as strengthening the integration of project teams to enhance design quality, strategic alignment of stakeholders at the planning stage, early contractor involvement (ECI) between the planning and design phases, and improving collaboration between design and construction teams. Further, a combination of high technical skills (e.g., design ability) and soft skills (can-do attitude, interpersonal skills, problem-solving skills, documentation skills, etc.) are needed to generate the desired improvement in design change management.

“…Guo et al [14] measured the changes in allocative efficiency and production efficiency of the British power supply industry before and after the reform of the power supply industry. Tsolas [15] calculated the input-output efficiency of 2275 samples of power distribution and transmission enterprises in Sweden. Tohid et al [16] studied and introduced Russia's electricity market operation mode of "complete separation of generation, transmission, distribution, and sale."…”

Input–Output Efficiency of Chinese Power Generation Enterprises and Its Improvement Direction-Based on Three-Stage DEA Model

This paper uses the three-stage DEA method to measure the input–output efficiency of China’s 23 listed power generation companies (mainly thermal power generation) in 2019, and uses the SFA regression model to eliminate environmental elements and random disturbances. The results show that in a non-homogeneous environment, the scale efficiencies of most power generation companies are greater than or equal to their pure technical efficiencies. These companies should first improve management and technical levels, and then optimize the scale of investment. Furthermore, after removing environmental variables, half of the companies should turn to increasing economies of scale instead of diminishing economies of scale. It can be seen that environmental factors, such as the degree of regional development and IPO time, have reduced the economies of scale of enterprises, so they should strengthen the communication between different regions, and the government should provide assistance to companies that are listed late.

“…They are part of various construction markets, but different from civil construction, infrastructure, or residential buildings, being their purpose to deliver a functioning facility or asset to End-Users. This type of projects encompasses a wide variety of fields of application and sectors, including but not limited to power generation, nuclear plants, industrial plants, renewables, power transmission and distribution, water treatment, Oil and Gas fields development and processing plants or treatment units [2][3][4][5][6].…”

The analysis of the planning activities of industrial construction projects can help to evaluate some of the causes that have an impact on the variation of execution times and can also contribute to identifying those activities and components that are most likely to experience or cause delays. Data analysis is facilitated by the use of techniques based on statistical programs, allowing delays to be unequivocally linked to the different elements that make up these projects. In a theoretical study, a simulation is carried out with data that are hypothetical but consistent with real projects, which are transformed and standardized before being uploaded to the statistical software. Using the statistical software’s graphical interface, the data set is analyzed from a descriptive point of view, unraveling the relationships between variables and factors by means of contingency tables and scatter plots. Using other techniques such as the comparison of variables and correlation studies, as well as linear regression and variance analysis, the characteristics are evaluated and the differences in project delays are investigated in order to determine, after the fact, which components have the highest rates of delay in execution times.
