The first five criteria can be categorized as project efficiency criteria, while the last one (environmental impact) can be categorized as part of the sustainability criteria (this will be discussed in more detail later). Additionally, three dimensions of project evaluation (economic, social and environmental) were identified. Out of the six evaluation criteria, time, cost, and quality continue to capture the economic dimension, while safety and site disputes account for the societal aspects and, finally, environmental impact takes care of the environmental aspects. Further, the authors contend that the iron triangle criteria (time, cost and quality) can be called tangible measures, while environmental, safety, and site disputes can be called intangible measures for project evaluation. Thus, the project efficiency criterion encompasses either tangible or intangible
