Purpose: Value Engineering (VE) is frequently applied to construction projects for better recognition of project scope and for elimination of unnecessary cost without impacting the functional requirements of individual components of constructed facilities. Despite all benefits of value engineering application, it is not applied in the construction industry in Gaza Strip. Therefor the aim of this research is to propose a framework that facilitates VE methodology application using Building Information Modeling (BIM) techniques. To achieve this aim five objectives were carried out: i) to survey and investigate the importance of Value engineering application in Gaza Strip for construction projects management improvement; ii) to investigate the factors influencing Value Engineering studies and apply it to the proposed framework; iii) to study and extend the use of BIM models to collect input data for the assessment framework and to assist in the automating evaluation process; iv) to Embed an AHP program into the evaluation phase of VE job plan to rank the alternatives. Design/methodology/approach: The researcher adopted both quantitative and qualitative research methods; it represents the use of quantitative research methods through the following tools: i) validity testing by consulting several experts in the field of construction management, ii) sample determination and due to the lack of experts in the field of value engineering in the Gaza Strip the researcher has adopted the sample of a snowball type, and then the questionnaire was distributed to the whole sample, which represents 25 individual of the population of the specialist construction management whom have knowledge in advance in value engineering. 20 questionnaire were collected out of 25 have been distributed, and finally the questionnaire was analyzed quantitatively in order to have meaningful data which was used in the next phase of the study methodology and results of a workshop stage. All required data was prepared and gathered to conduct a value engineering workshop. The workshop has been combining quantitative and qualitative methods. Seven specialists in the construction industry whom experience more than 20 years were anticipated in the VE workshop. The proposed framework has been applied to a case study from the Gaza Strip to work on improving the basic functions of the elements under study by reducing cost without compromising the essential functions. BIM tool presented on Revit program was used for visualization terms and BPMSG program was used for AHP evaluation techniques. Originality/ value: The research area is not common in Gaza Strip and it is highly needed due to the scarcity of funds for construction projects associated with high prices of building materials. Moreover, this study will add to the current body of knowledge about VE application in Gaza Strip. This study contributes significantly to consider BIM as a tool of speculation phase in VE job plan and AHP in the evaluation phase. Findings: The study results concluded that the Value Engineering is still not commonly applied in the construction industry in the Gaza Strip. The study got the benefit from the results of the questionnaire to improve the performance of the workshop by focusing on the most important factors in the value engineering studies. As a result of this study, after the application of value engineering methodology using the proposed framework on a case study represented in a conference building the cost of the element under investigation was reduced by 57.5% without compromising the basic functions of the component.Keywords: Value Engineering (VE), Building Information Modeling (BIM), Analytical Hierarchy Process (AHP)
