Practices improvement of building information modeling in the Egyptian construction projects

Reduced Reinforced Concrete Material Waste (RRCMW) in building projects is regarded as a critical issue that must be managed. The main purpose of the research is to illustrate the importance of BIM in construction. Also, it is found that the main objectives of this paper are to study the improvement of practicing BIM in Egypt and, practicing of BIM in construction industry in Egypt is also measured. Two questionnaires survey are conducted. The first questionnaire is to measure the improvement of using BIM during the last 7 years and it is discovered that there is a massive improvement in using BIM in this period. The second questionnaire is to determine the adopting value of BIM in Egyptian projects in order to meet the study objective. So, based on the questionnaire analysis, it is discovered that about 94% of consultants actually practicing BIM in 3D while about 72% of contractors agree with practicing BIM in 3D. Also it is found that about 86% and 78% of consultants actually practicing BIM in 4D and 5D while only about 43% and 40% of contractors agree with practicing BIM 4D and 5D model respectively. Only about 61% and 58% considered that BIM is important in 6D and 7D respectively because it isn't widely used in Egypt and engineers use BIM up to 5D. As a result, the findings reveal that the number of consultant's site engineer's respondents are more than contractors because the usage of BIM is effective in the field of design and consultancy more than using in site and while BIM isn't extensively utilized in Egypt, engineers should be familiar with it because it will be a useful tool in the future. So, the main purpose of this study is to illustrate practicing of BIM in the Egyptian construction projects and study the improvement of using BIM during the last 7 years in Egypt because BIM is considered as an important technology used to reduce waste in construction projects from design stage to construction and operation stage but still not used in Egypt in a wide range till now, so it is very crucial to study this issue. Also, another main objective of this study is to compare the development done in using BIM during the last 8 years to make sure that using BIM in Egypt is going on and developed.
