6.7 Evaluating Private Cooperative Housing Projects Case Study

6.1 Social Profits:
Social income is defined as the value of the increase in supply less the value of increase in demand. Social profits can be more or less common for both public and private projects; thus, it is better to impose rules to eval-uate uncommitted social income.
The right Appraisal is absent in the case study under-taken by this research; therefore, social benefit is nega-tive; it may shift towards zero, or slowly towards the positive. However, some authors suggested that estima-tors must consider the use as a social income . Because the social income produced by the project is not the real measure of its yearly value to society.
6.2 Present Social Value (PSV):
After knowing the yearly social profits, they can be tied to
• To consider the increase in migration of rural labour to urban.
Some private projects have some social benefits, but they did not have social cost-benefit analysis to show that. In our case study the social profits are negative. Therefore, this paper recommends that many of these projects should have been shut down before starting.
7 Evaluating Private Cooperative Housing Projects:
Evaluating projects is part of monitoring. It is done for stages. Further, evaluator must take in consideration the interests of neighbours, and the conflicts between the interests of individual developers and the community. However, it is important to consider contribution of pro-jects for the development; and to realize that "develop-ment will only take place if it is for the individuals, firms and organizations wishing to develop."
7.1 Methods for Evaluating the Project:
Evaluators must do different calculations to be able to evaluate the private housing projects. Despite, it is not part of this study to go for such calculations, but archi-tects can draw a procedure for them, this procedure fol-lows the following steps:
• Estimating the private
• Computing the present social value.
• Finally, authorities must do projects if they are socially profitable; but if projects are not so, they have to close them down from the beginning.
7.2 Differences between evaluating private and pub-lic projects:
The methods for cost-benefit analysis for cooperative schemes are similar to those of the public. They have two main differences related to the capital and profit.

First: The Capital Opportunity: Opportunity cost of the capital in private projects is different from that of public; in public, governments invest money for public, if not for one project, they do for another one. But, in pri-vate or cooperative projects there are other possibilities in the capital:
• Capital may be used for improper pro-jects.
• Capital may be invested in places which have the last priority in national or regional planning
• Capital may be kept without investment.

Second: The Profits: The difference in profits can be summarized as follows:
The profit in public results in extra consumption by increasing wages and salaries. But, profits in private pro-jects encourage consumption among wealth, which has fewer profits than extra consumption. Therefore, it is important to conduct the social cost-benefit analysis for the private
