Building foundations are commonly overlooked when it comes to sustainable construction practices. Concrete piles are a major source of carbon dioxide emissions in buildings. In order to determine how sustainable a concrete pile is, several factors must be researched. The use of local or recycled materials or pozzolans helps to make these piles more environmentally conscious. However, since there is not much historical data, it cannot be determined to a definite degree how sustainable the piles are without the use of expert opinions. Variables such as ‘fairly sustainable’ or ‘very unsustainable’ must be utilized to make this determination. These variables are manipulated using fuzzy logic, resulting in imprecise variables like ‘very unsustainable’ to be used.
The thesis presents five different models: Triangular, Translational, Mamdani, Rotational, and Angular. These models are described in detail and the last four are compared to find which model fits best, based on the input variables. The models are presented in C# programming language. The models are used to determine the overall sustainability of a concrete pile construction project
