“…The construction industry represents a significant percentage of many countries Gross Domestic Product (GDP). According to World Bank, developing countries are responsible for approximately 6-9% of the GDP [5,6], therefore the success of the construction industry often leads to the promotion and maintenance of long-term economic growth and stability. In recent years, multiple attempts have been made to improve construction project productivity and success rates, which frequently represent the fundamental principles for the successful implementation of the projects management and optimization.…”

The Construction Industry is a complex and fragmented industry worldwide with regards to its supply chain, products, and processes, and is faced with a similar dilemma as faced by manufacturers during its time in past decades. Scope, time, and cost are the triple constraints of project management and leading factors in defining the project performance. Productivity and efficiency of each construction project is measured through its triple constraints, therefore the factors that affect project success are significantly important. Despite the importance of understanding project performance indicators, few empirical studies have been conducted over the last decade in terms of analyzing the factors that determine the performance of high-rise buildings in Engineering, Procurement, and Construction (EPC) projects. Hence, the aim of this paper is to analyze and rank EPC critical activities across large-scale residential construction projects in Iran, by using the TOPSIS method as a multi-attribute group decision-making technique. Results indicate that engineering design, project planning and controls are significant factors contributing to the project performance. In addition, engineering has a pivotal role in project performance and this significance is followed by the construction phase. On the contrary, all believe procurement is more important than Construction phase.

“…The literature of sustainability reported that this concept has been applied in different fields such as tourism, textile, supply chain, and oil and gas (Castro-Alvarez et al, 2018;Heravi et al, 2017;Lambin & Thorlakson, 2018;Lozano et al, 2015;Mowforth & Munt, 2015;Shen et al, 2017). As can be seen, one of the fields in which sustainability is being implemented is Construction Industry (CI) (Lopes et al, 2017;Mavi & Standing, 2018). Heravi et al (2017) stated that ten percent of gross domestic products and seven percent of employments belong to CI.…”

Sustainability has become a key concern for project selection in construction industries. Determining the best sustainable project based on various sustainability attributes is a very complicated decision. Accordingly, developing a suitable decision support framework can be very helpful for decision makers to attain planned business goals and complete projects at the right time with good quality. This research develops a decision support model which helps managers to understand the concept of sustainability in construction project selection and choose the best project using a new integrated Multi-Criteria Decision Making (MCDM) approach under uncertainty by integrating Fuzzy Preference Programming (FPP) as a modification of Fuzzy Analytical Hierarchy Process (FAHP), with Fuzzy Inference System (FIS) as a fuzzy rulebased expert system. In the first phase of the research, fifteen sustainability attributes were selected. In the second phase, the final weight of each attribute was computed by using FPP. In the last phase, the most appropriate project was selected by running the weighted FIS. The results showed that Project 3 (P3) is the best project. Finally, two different evaluative tests were also applied to verify the validity and robustness of the developed model.

“…The construction industry plays a key role all over the world as it accounts for a large proportion of the country's total employment and makes a significant contribution to a country's overall income. For instance, [5,7,8] reported that construction industry offers employment to people and a better quality of life to countries and positively associated with the success and progress of any economy. One of the most important factors affecting construction industry's growth is productivity and it is associated with the labour performance.…”

The construction industries face several challenges related to productivity. Productivity mainly depends upon labour effort and performance. The poor productivity of labour is one of the major reasons of time over-runs and increasing cost in construction projects. Our study aims to build a comprehensive assessment on the relationship between various factors that affect labour productivity in the construction of prestressed concrete Buildings in Ghana. A sample of 200 re-spondents collected from workers of Construction Company in Ghana. The questionnaire was designed which comprises two parts; the first part contains background information of the staff of construction company while second section explores the opinion of the staff regarding factors af-fecting labour productivity. The Smart-PLS was utilized to analyze and estimate the relationship among construct variables. By utilizing relative importance index and multiple linear regressions, it is identified that the management factor such as inadequate incentives; material factor such as poor quality of material; labour factors such as poor quality and training of labors; supervision factor such as incompetence of site supervisor; equipment factor such as frequent damage of equipment have a negative and significant relationship with labour productivity in the construc-tion of prestressed concrete buildings in Ghana. The findings of this study recommend that in order to improve labour productivity, the construction industries must conduct labour productivity measurements by adopting schedule for procurement of materials, safety programs, motivational system, and frequent meeting with project professionals.
