There is a lack of an efficient systematic approach to the selection of appropriate construction methods for modern building systems. Identifying key criteria is necessary to help decision-makers in implementing the principles of this process. The present article was conduct for the same purpose. In this article, after reviewing of the literature, we found that construction experts’ opinions did not consider until now. Thus, we considered the opinion of experts in the field of the construction industry (Technical and executive specialists of the Afghanistan’s Ministry of Urban Development and Housing, Technical and executive specialists of the Kabul Municipality and Omran Houlding Group). For identifying key criteria, “64” criteria have been extracted that affect the selection of modern building systems and are classified into “six” economic, qualitative, social, environmental, executive and technical groups. A comprehensive study conducted through the distribution of questionnaires. The collected data were analysed using SPSS statistical software; the main criteria ranked by using “Friedman’s statistical test”. Based on the results of statistical tests, 18 criteria were determined and ranked as fundamental criteria. Therefore, paying attention to these criteria for the selection of appropriate construction methods for modern building systems can help experts in the country of Afghanistan.
Cost overruns vary evidently almost in every construction project, but their magnitude from project to project. The cost overruns have hit down the economy and the reputation of many Construction Company and hit down the economy and the reputation of many construction companies around the world. Many project management tools are designed to manage the project's budget. However, cost management is still considered poor, as there are many cost overruns in the construction industry. Thus, this work is aimed at identifying and clustering potential factors of the excess cost of construction projects in accordance with their original groups using a thematic approach. Basically, through a literature review, all the potential factors that could cause cost overruns were carefully analyzed before they were grouped into seven (7) groups of underlying factors, namely: project, contract, client, contractor consultant, workforce and external. Each potential factor was clearly explained with some examples based on Malaysian case studies to illustrate the cost overruns scenario. These findings may help in the future to focus on how to mitigate critical potential cost-overs to reduce or overcome its impact on all involved stakeholders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
