Purpose Construction industry bears a lot of casualties and accidents more than other high-risk industries annually. Thus, the use of new technologies such, as building information modeling, automatic rule checking, information technology-based safety systems in order to implement the rules and safety standards, better controls the performance of workers on site and make high coordination between operational executives, leading to create a secure environment in projects by reducing accidents. The paper aims to discuss these issues. Design/methodology/approach In this study, a researcher-designed questionnaire was distributed among 200 companies that are active in the field of construction to evaluate the effect of building information model (BIM) for safety projects and barriers to adoption. Only 70 percent of questionnaires were returned. Statistical Package for the Social Sciences analysis has been used to determine the correlation coefficient among the respondents. Findings The results show the factors that lead to failure in the adoption of BIM in Iran are lack of well-trained personnel, proper social infrastructure, guidance and governmental supports. Originality/value Finally, the authors presented solutions for overcoming barriers and proposed some factors leading to the successful adoption of BIM in Iran.

A significant part of the annual budget of developing countries is allocated to civil projects and the construction industry. In Iran, between 30% and 40% of the total budget of the country `is allocated to this industry. However, the implementation of these projects is often faced with several problems that cause delays and increase costs.The main objective of this research is to identify, analyze, and prioritize factors effective in delays in the construction of port operational area and to offer suggestions for preventing or reducing these delays. The statistical population of the study consists of employers,investors, consultants and contractors involved in the construction of port operational areas in Iran.Data were collected through a questionnaire and were then analyzed using structural equation modeling in VPLS software. Results showed the most effective factors of the delay in the construction of port operational areas to be inadequate monitoring(11%), poor planning and time scheduling (19%) ABSTRACT A significant part of the annual budget of developing countries is allocated to civil projects and the construction industry.

PurposeThe purpose of this study is to compare the trend of academic project management research in Iran and the World in five-year periods with a text mining approach and TF–IDF method.Design/methodology/approachThe research population consists of 1205 theses presented between 2000 and 2019 in Iranian universities. The central library website of the mentioned universities was used for data collection, and the text mining approach with the TF–IDF method was used for data analysis.FindingsThe remarkable results of this study include: Concrete structures are the most frequent among structural systems, Risk Management is the most frequent among PMBOK Knowledge Areas, Design-build (DB) system is the most frequent among Project Delivery Systems, Engineering, procurement and construction (EPC) is the most frequent among DB Project Delivery Systems, Financial Management is the most frequent among specialized construction knowledge areas, Soft Skills is the most frequent among Global Trends, Contracting Companies is the most frequent among Project Parties, Construction Projects is the most frequent among Project Areas, Power Plant and Refinery is the most frequent among Project Subjects, Optimization is the most frequent among Problem-Solving Approaches, Fuzzy Logic is the most frequent among Novel Algorithms and Motivation is the most frequent among Soft Skills.Originality/valueThe innovative aspect of this research is that for the first time, text mining has been used to analyze academic research on project and construction management, and also for the first time, academic research on construction industry in Iran has been compared with global research.

Un nuevo sistema de gestión de costes de proyectos de construcción para aumentar la competitividad y la trazabilidad para entornos de proyectos. El objetivo principal de la investigación es utilizar nuevos métodos de cálculo de costes en los proyectos de construcción para reducir y controlar las desviaciones de costes y algunas limitaciones que presentan los modelos tradicionales. La hipótesis de la investigación se basa en la capacidad sinérgica del cálculo de costes basado en actividades centradas en el rendimiento, en combinación con el método de cálculo de costes objetivo para fomentar la competitividad del sistema de control de costes para entornos de proyectos. El método se elaboró para controlar los gastos directos y generales del proyecto durante su ejecución. Se realizó una entrevista con 26 directores financieros en dos o cuatro ocasiones entre junio de 2016 y mayo de 2017 con el fin de validar y modificar el método. Siguiendo una entrevista semiestructurada, el método propuesto contribuyó a aumentar la precisión, la certidumbre y la rastreabilidad de los costes y proporcionó la integridad del sistema contable, técnico y operacional. Además, se analizan las desviaciones y se reducen los costes al considerar las condiciones competitivas y estratégicas. También se limita el coste objetivo de los paquetes de trabajo y se genera una alerta al finalizar cada uno de ellos. Además, de acuerdo con el test de Friedman, existe una capacidad competitiva significativa en comparación con el método convencional de control de costes en los proyectos y también se aplica en un estudio de caso. This research proposed a new method for project cost management based on Competitiveness and traceability in a case study and operational situation. The research hypothesis is based on the synergistic ability of performance focused activity-based costing in combination of the target costing method for encouraging competitiveness cost control system for project environments. The method was developed to control, direct and overhead costs of the project during its progress. Also, it uses the feature of activity-driven and different resource drivers to determine the types of costs with the effect of time driver for each activity. An interview was conducted with financial managers during two to four times with the aim of validating and modifying the method. According to a semi-structured interview, the proposed method contributed to increase the precision, certainty, traceability of costs and provided the integrity of the accounting, technical and operational system. It also analyzes deviations and reduces costs by considering competitive and strategic conditions. It's also limiting the target cost of work packages and causing an alarm on the completion of each. According to Friedman test, there is a meaningful competitive ability compared to the conventional cost control method in the projects and it is also implemented in a case study.
