Purpose New methods have been introduced as revolutionary approaches in the construction industry, such as off-site manufacturing (OSM) and building information modelling (BIM). Although these approaches can provide many benefits, there are still barriers to meeting the expectations of improved construction productivity via their implementation. Hence, the purpose of this paper is to critically review the capabilities of OSM and BIM techniques, as well as their potential interactions, in productivity improvement. Design/methodology/approach A scoping review approach was adopted, where 100 peer-reviewed journal articles were collected to analyse the capabilities of OSM and BIM, as well as their potential interactions, in productivity improvement as assessed by key productivity indicators (KPrIs). Findings The results reveal seven BIM-based capabilities and six OSM-based capabilities, as well as 12 potential OSM–BIM interactions that have significant potential for satisfying KPrIs. Originality/value An integrated framework has also been developed to clarify and conceptualise the roles of OSM–BIM interactions in their designated KPrIs. The research has developed insightful and practical references for strategic planning and management in OSM–BIM-based projects.

since the construction activities involve most complex processes and the most intensive administrative atmosphere as well, the accident events come raised in different situations and due to various causations. Most of the construction accidents originate from human errors and operation sources such as equipments and facilities in work processes. Most accidents lead to the loss of life, injuries and loss of properties. The other possible results due to the errors, unsafe acts, and unsafe conditions can be categorized in Near miss events (no result of injuries), and incidents (likelihood of injuries or loss of property). The role of a tool by which the causations and the processes can be highlighted is vital to save the projects not to be trapped. In order to recognize the reasons or the factors contributing to accidents, several theories have been developed by researchers. Domino theory as a structural map has been one of the most understandable and widely acceptable theories among the accident theories. The authorities employ it to control the factors causing undesirable events and to prevent the errors before being made. The aims of this paper are firstly, to describe the shortcomings of construction processes contributing hazardous situations. secondly, highlighting, the ways to apply Domino theory, and thirdly, to define how to establish a remedy model to prevent accidents in construction projects based on domino theory in simple statements.

Reinventing construction is the key to improving productivity. This reinvention refers to not only inventing advanced materials and equipment but also developing new operating systems for construction projects. Inadequate application of advanced techniques impedes the operating system. Furthermore, the capabilities of advanced techniques may not cover all the areas required to meet the expected productivity level. The implications of these advanced techniques need to be reinforced by a range of productive fundamentals that remain unclarified. Further, the pathways through which these fundamentals can be aligned with the implementation of advanced techniques remain under-researched. Hence, the objectives of this research are as follows: (1) to clarify how the selected and common advanced techniques applied in this paper influence construction productivity; (2) to determine the range of productivity fundamentals required to reinforce the implementation of the advanced techniques necessary to fulfil productivity expectations; and (3) to conceptualise the integration of these productivity fundamentals with the application of advanced techniques. A scoping review of 128 articles was used to identify which fundamentals can contribute to achieving performance targets once practising these new advanced techniques. The findings reveal a comprehensive range of productivity fundamentals that are able to reinforce new advanced techniques through different pathways of their applications.

During the recent years different people in charge have been considered about different costs of the plants in the construction industry. Usually it seems to be a big challenge for different people in charge and mainly contractors to decrease the costs of the projects through the optimum use of construction plants in order to increase the quality of the project and decrease time and cost. During the current study, researchers have been investigated about the construction plant use in the construction sites and also its effect on the quality and also time of the project. Forty three people in charge with the construction projects have been participated in the current survey. After analyzing the required data through SPSS software and based on the mean index of the scores five items have been identified as the most important issues in the construction management regarding the use if plants namely: The effect of spare parts availability to decrease downtime, the effect of employing expert mechanics to increase the repair quality, impact of gasoline and petrol availability to decrease wasting the time, impact of periodic control and serviceability of plants and equipment to increase productivity, impact of training persons who are involved plants and equipment to increase productivity. It goes without saying that extracted factors have significant role in the construction projects and different contractors should consider them in their projects.
