There is little research on the dynamics of the change environment and the AEC organizations' approaches to BIM adoption and implementation. A considerable number of BIM enablers have been identified and/or developed in the extant literature. However, stipulating BIM implementation enablers per se provides only a static view that is not adequate for describing effective management of BIM implementation in Architectural, Engineering, and Construction (AEC) organizations. This study is the second part of an ongoing research about BIM implementation enablers. In the first paper "Building Information Modelling (BIM) adoption and implementation enablers in AEC firms: a systematic literature review" (Abbasnejad et al., 2020) the organizational BIM enablers have been identified. The aim of this second paper is to (1) further review and validate the key BIM implementation enablers using both the existing literature and expert interviews, and (2) develop a structural model of the key enablers using the ISM technique to understand the mutual interaction of these enablers and identify the driving enablers and the dependent enablers. Twentyeight enablers for BIM implementation were initially identified from the literature and subsequent discussion with experts from academia and industry has been conducted to select most key BIM implementation enablers. Eleven enablers were finally chosen based on the literature review and expert interviews and the Interpretive Structural Modeling (ISM) technique has been adopted to evaluate the contextual interrelationships among them. MICMAC (Matrix Impacts Cross-reference Multiplication Applied to a Classification) analysis was employed to classify the eleven enablers based on their dependence and driving power. The results indicate that there is no enabler in the autonomous cluster and this therefore signifies that all enablers are required for the implementation of BIM. BIM leadership and top management support have been identified as the enablers with the highest driving power in the initial stages of the BIM adoption and implementation process and for that reason, these enablers demand a greater priority given that there are other dependent enablers that will be impacted.

The industry has been criticized by researchers and practitioners as being unable to apply newly created knowledge effectively to innovate. The fragmented nature of the construction industry reduces the opportunity of project participants to learn from each other and absorb knowledge. Building Information Modelling (BIM), referring to digital representations of constructed facilities, is a promising technological advance that has been proposed to assist in the sharing of knowledge and creation of linkages between firms. Previous studies have mainly focused on the technical attributes of BIM and there is little evidence on its capability to enhance learning in construction firms. This conceptual paper identifies six

of BIM that act as triggers to stimulate learning: (1) comprehensibility, (2) predictability, (3) accuracy, (4) transparency, (5) mutual understanding and (6) integration.

Concrete is the world's most popular construction material, because of the benefits that it can provide for construction industry and structures. Concrete, like other products has environmental effects occurring from it raw material process of resource extraction to producing and transportation. The basic impacts of cement productions are the CO2 emissions, which resulted in direct effects to global warming, raw materials depletion and energy consumption. Cement manufacturers are a source of greenhouse gas emissions, accounting for around 7% to 8% of CO2 globally. It has been proven that half of the CO2 in manufacturing procedure of cement is released by limestone decomposition in the kiln and the other half is due commonly from fuel burning to operate the kiln. This paper draws attention to some different influences of concrete on the environment and highlights the benefits of fly ash concrete as a new finding in the world of construction by comparing its properties and effects with the regular concrete. At the end, some guidelines for decreasing destructive environmental impacts of concrete are suggested. Therefore, in spite of so many initiatives which have been done in the field of construction but still the improvement of eco-friendly materials seems to be lacking and more efforts are needed in the environmental discussions and education of civil engineers.

Also, in defining the different maturity levels of BIM, the concepts of 4D, 5D and 6D are used to indicate the elements and benefits of increasingly complex BIM models. In this paper, the significant purpose should be per-suited is the some conflicts and finding some alternative resolution for disputes during the life cycle of construction with BIM. These disputes could be produced with some parts of construction process that mention them in continuous.

One of the most significant issues which improve the profitability of building is to use a preventative policy to reduce construction waste. Different research into construction waste minimization techniques have been undertaken so far, but a comprehensive approach that can be effective in various areas in construction has not been provided. Building information modeling (BIM) as an approach in the construction industry has developed methods to cut construction waste during the design and pre-construction phase. This paper will focus on the construction waste origins, current practices of waste reduction and finally describes the potential application of BIM to design out waste.

Following the Occupational Safety and Health Act of 1970 contractors began implementing safety programs and tools to reduce occupational safety and health hazards on construction sites or even prevent it in design stage. One new tools which may be used is building information modeling (BIM). This article introduces readers to the concept of BIM, its uses and benefits, particularly with respect to construction safety.

Traditional scheduling methods of construction have been used for building of structures previously but they are no longer suitable for producing robust work schedules. Technological innovations have assisted the construction industry to avoid a lot of uncertain hazards through management of resources in an efficient, effective and affordable manner. Building Information Modeling or BIM offers the potential to improve cost, scheduling and co-ordination of infrastructure projects. Building Information Modeling in terms of 4D modeling saves a lot of time and money over traditional scheduling processes. On the other hand, enhancing the reliability of planning is a fundamental factor in achieving stable construction flow and subsequently, high productivity and improved product quality. This paper compares BIM-based scheduling with the traditional method and also focuses on understanding how BIM solves existing problems in the traditional method of scheduling.

As a matter of fact, the construction industry contributes in a significant proportion of economic and social aspects. However, it is also considered to be the most hazardous industry in terms of personal safety and health.Many factors are involved in the accident occurrence at construction site. Some important elements that create a significant portion of accidents include: safety management error, poor training programs, human element, act of god, outdated procedure and no clear monitoring policy. Although some of these items are inevitable, but the occurrence of the largest part can be prevented.Therefore, for improving the safetyin a project each of these items should be analysed and a practical approach introduced. In general, near miss, incident and accident are three dependent levels that mainly lead to injury. Risk and hazard are allocated in first level which means near miss, therefore, no on-time identification of hazard and risk causes to create incident and preventing accident in incident stage is unavoidable. The aim of this paper is to focus on factors influencing in theimprovement of safety performance at construction site and suggests a clear procedure to develop safety performance byreducing risk and hazards.
