“…If construction companies can effectively control these key factors and formulate prevention strategies, not only can cost overruns be avoided, but overall profits on projects can be augmented (Forcada et al, 2017). The analysis of risks and proper management is a critical part of the whole decision-making process particularly in engineering projects (Kamalzadeh et al, 2019;Mirmozaffari et al, 2020b). When these projects fail to achieve their intended outcome in the first attempt, the organisations are left with two options.…”

The current COVID-19 pandemic is making a huge impact on society. Most projects are either abandoned or halted due to this pandemic, especially in developing countries. We have conducted this study to evaluate the impact of COVID-19 pandemic on construction projects by using the concept of rework projects. 'Rework project' is a class of projects that are initiated to achieve the intended objectives in the second attempt after failing to achieve the goals in the first attempt. People who were involved in the selected projects in different capacities were interviewed and analysis of the responses was performed. The unique challenges/risks such as time urgency, overburdened resources, and mobilization of contractors, inappropriate documentation gaps, and technological changes were highly significant in rework projects. By having clear recognition to these highly significant risks, organizations will be well equipped in devising strategies to manage and complete the rework projects in the post-pandemic world.

Nowadays, as the population of urban areas increases, the need for consumption increases as well. This amount of consumption requires power generation centers with large volumes exploiting that it needs to be big enough, which guides technology towards bulk power transmission systems. In doing so, two types of power transmission systems, including HVDC and EHVAC, can be studied. However, since none of the above technologies has been used in developing countries, a decision should be made to introduce and develop any of these technologies. Applying both technologies together would not be cost-effective. A decision-making development needs the principles of conflicting purposes for alternatives and the selection of the best choice based on the needs of decision-makers. Multi-objective optimization methods may well provide a solution for this selection. Thus, this paper studies deciding on the introduction and Development of HVDC and EHVAC in a developing country, Iran. To this end, measures of this selection are described in detail, and then, AHP, one of the well-known MCDM method, is used to make the final decision.

“…It is posited that the pandemic particularly afflicted businesses in less-developed countries, such as Iran (Bapuji et al, 2020). Regarding the dependency of Iran on the steel industry to re-establishing its infrastructures (Kamalzadeh et al, 2019), and severer than businesses in Europe, where sections related to the construction industries were operating at 25%-30% below their standard capacity (de Vet et al, 2021), the country's steel manufacturers have significantly been impaired (AHK-Iran, 2020). Such impairment, expounded later as a jolt, is speculated, and not yet probed into, to be inducing a crisis, and consecutively bringing a framebreaking change that disrupts cultures (Morais et al, 2020).…”

A crisis stems from an unexpected negative change in the environment, threatening the high‐priority values of the organization. As a crisis, the COVID‐19 pandemic jolted businesses worldwide, necessitating an investigation into the aspects of such an unsolicited change in the culture and effectiveness of organizations. With this aim, this research is based on a two‐step explanatory case study of a manufacturing firm. In the first step, to measure the change in the OC, a paired‐sample test was conducted using the Denison organizational culture survey model. Next, a qualitative inquiry was carried out, and the data were analysed through theme analysis. The results show significant changes in all 4 traits, including strategic direction and intent, vision and agreement, explained by the 12 qualitative themes. Ultimately, this study answers the long‐overlooked impact of a jolt, inducing a crisis, on the organizational culture. It sheds light on the importance of clarity of vision, core values and trust during a crisis.
