General Assumptions. The overall cost estimate of the UBC Neighbourhood District Energy System (NDES) is a Class C estimate, which the Association of Consulting Engineering Companies British Columbia (ACEC-BC) defines in the following way: “An estimate prepared with limited site information, based on probable conditions affecting the project. It represents the summation of all identifiable project elemental costs and is used for program planning, to establish a more specific definition of client needs and to obtain preliminary project approval. Class C estimates typically have an accuracy of +/- 25-40%.” However, some elements of this cost estimate have a higher degree of accuracy and can be classified as Class B, defined by ACEC-BC in the following way: ”Class B estimate (+/- 15-25%): this is prepared after site investigations and studies have been completed and the major systems defined. It is based on a project brief and preliminary design.”
