Still, they overlooked existing building alternatives in terms of changing the kind of usage of such buildings. So, they need an integrated model between value engineering and building information modeling, especially applicable to an existing structure, to determine the optimum usage type for the existing building. Value engineering and building information modeling must be connected to profit from both outputs simultaneously. And used the multi-criteria decision-analysis method. Today’s analytic hierarchy process is the most widely used. This paper provides an integrated framework between value engineering and building information modeling that can be applied to existing buildings to assist in determining the best alternative in terms of the type of usage for such existing structures by conducting BIM methodologies such as a feasibility study which includes present value, cash flow and the bank interest rate, and BIM software such as Revit and Primavera. The multi-criteria decision analysis method was used to focus on what is important, logical, consistent, and easy to use.

MCDA which considered a process for evaluating options with conflicting criteria and choosing the best solution, similar to a cost–benefit analysis, but evaluates numerous criteria rather than just cost.

The findings revealed that this integrated framework, which includes feasibility studies and comparison tables, may be implemented in the future while taking into account time and location constraints.The MEP (Mechanical/Electrical/Plumbing) Modeler is an integral extension to ARCHICAD and now included free. Architectural practices and architectural departments of A/E firms using ARCHICAD can use MEP Modeler to create, edit or import 3D MEP networks (ductwork, piping and cable trays) and coordinate them within ARCHICAD.
