Abstract: The use of value engineering (VE) in construction industry has grown significantly in view of its extensive benefits. This paper presents a software that integrates building information modelling (BIM) and VE in construction projects to support project stakeholders. The software is developed to automate the process of data extraction and manipulation from BIM and processing the extracted data to evaluate competing alternatives. A vital stage in applying VE is the evaluation of alternatives through different assessment criteria by project team members, which places subjectivity in perspective. To reduce subjectivity in the developed software, analytical hierarchy process (AHP) algorithm is used to support VE multi criteria decision making. The developed integration software was implemented in prototype software that is named Value+. It is a three-tier software, which utilizes an object-oriented BIM model. It has been applied to an actual case study to demonstrate and verify its use and capabilities. The project is phase 2 of a new liquid natural gas (LNG) support campus with 1000 m2 land area. Nine evaluation criteria were selected to choose the optimum solution from three alternatives for a slab structure system.
