Value engineering is a powerful tool for solving problems based on creativity and function and it has been used in construction projects for many years and could prove its advantages to all members of this industry in recent years. However, like other tools, it has the ability to upgrade and increase productivity. This study attempts to provide a consolidated framework for value engineering and risk management. Accordingly, after identifying the model’s factors in these two areas, models which are more associated with the construction industry have been chosen. Based on experts' opinions, top models were selected for integration. By using the Delphi method, experts reached a consensus for sequence of the framework steps. After necessary synchronization, this framework implemented in Ports and Maritime Organization as a verification. By using this framework, the process of value engineering is improved. Risk management (associating experts who are aware of all aspects of project) was executed in two levels and based on fuzzy logic. It resulted in spending less time and money.

Considering only two dimensions (cost and time) among different dimensions that have been defined for evaluation success of rehabilitation and renovation process in urban decay contexts, and with attention to the special condition of Iran, the current trend is clearly inappropriate. In this regard, this study, considering the important role of suitable housing and urban space in the welfare of the citizenry, aims to facilitate and amend this process by evaluating strategies to encourage non-government sector in order to comprehensive participation in the mentioned process. For this purpose, using Descriptive-Analytical methodology, the research hypotheses were evaluated from the perspective of descriptive and illative statistics. The results showed this reality that despite neglect to indirect encourage instrument (Non-Grant Base Instrument) in order to encourage investors to investment in rehabilitation and renovation process, these instruments can be useful similar to direct encourage instruments that mainly have a financial base. Also test results of the second hypothesis showed a correlation between desire to investment in decay urban contexts and use of industrial construction methods in these contexts; this can provide suitable opportunity for decision makers in order to encourage use of industrial construction methods, because they have different kinds of benefits that inherently increase tendency of both the investor and citizenry to investment in urban decay contexts.
