This paper extends the build-operate-transfer (BOT) concession model (BOTCcM) to a new method for identifying a concession period by using bargaining-game theory. Concession period is one of the most important decision variables in arranging a BOT-type contract, and there are few methodologies available for helping to determine the value of this variable. The BOTCcM presents an alternative method by which a group of concession period solutions are produced. Nevertheless, a typical weakness in using BOTCcM is that the model cannot recommend a specific time span for concessionary. This paper introduces a new method called BOT bargaining concession model (BOTBaC) to enable the identification of a specific concession period, which takes into account the bargaining behavior of the two parties concerned in engaging a BOT contract, namely, the investor and the government concerned. The application of BOTBaC is demonstrated through using an example case.

Using remote sensing technology becomes an important method for monitoring the land-use practice in China. For pursuing economic benefits, the local governments often implement various development programs by using state land illegally, thus it is essential to identify these illegal cases in using proper techniques such as remote sensing technology. The identification of those illegal cases will help government to adopt necessary punishment measures. It is believed that sufficient punishment measures will bring down the number of cases in using land illegally. In other words, increasing monitoring frequency will be able to control the land use practice. This paper is to build up a model using Game Theory for finding out an optimal monitoring frequency which enable the proper control over land use and at the same keep the monitoring costs to the minimum level. The model balances the monitoring frequency and the possibility of committing illegally land use by the local governments. A hypothetical example is presented to demonstrate the application of the model.

With a view of sustainable development, different kinds of farmland consolidation are reviewed. A planning and design mode for eco-sustainable farmland consolidation, which integrated the ecotypic board, the ecotypic tunnel, the ecotypic island, and the ecotypic boundary, is proposed. Then, an actual case of farmland consolidation, a project located in Yinzhou County, Zhejiang Province, is used to demonstrate the effective application procedures of the planning and design mode.

Sustainable performance is expected to become a major factor when examining the feasibility of a construction project in terms of its life cycle performance. The study on which this paper is based developed a simulation model, using system dynamics methodology, to assess the sustainable performance of projects. Three major factors are used to examine project sustainable performance (PSP): the sustainability of economic development (E), the sustainability of social development (S), and the sustainability of environmental development (En). Sustainable development ability (SDA) was used as a prototype to evaluate the degree of sustainalbe performance. The simulation software ‘ithink’ was used to help with the application of the model to a real life case. This paper explains and demonstrates the procedures used to develop, the model and finally offers an approach for assessing the feasibility of a construction project in terms of its sustainable performance.

This paper extends the build-operate-transfer (BOT) concession model (BOTCcM) to establishing a risk concession model for BOT contract projects. The decision for a concession period is one of the most important decisions in determining a BOT contract. BOTCcM presents an alternative method to assist in determining a concession period that can protect the basic interests of both the investor and the government concerned. However, there is a major limitation in using the model, namely it gives no consideration to the impacts of risks on the estimation of various economic variables in the model. This study considers the risk impacts to the BOTCcM model and presents an additional risk concession model. This model provides an approach for formulating a concession period to consider the impacts of risks and, at the same time, protect the basic interests of both the investor and the government concerned. A hypothetical case is used to show the procedures of formulating the risk concession period through the assistance of the Monte Carlo simulation method.
