Increasing interests of circular economy (CE) principles applied into construction projects has led to the development of assessment methods for their justification. The use of smaller quantities of construction materials, materials of higher quality and durability, and recycling of construction waste are all requirements of today's aspiration for a circular economy, but it is necessary to assess their environmental and economic sustainability. This paper presents a review of the current assessment tools of circular economy projects applied to the construction industry, such as LCA, LCC and CBA. The main objectives of this study were to provide a categorization of CE concepts applied in the construction industry (CI) and to review assessment methods used for evaluating CE projects in CI. This paper selected and reviewed 96 published papers and classified them into one of five aspects of CE highlighted in this study: waste management, reducing the impact on the environment, material & product design, building design, and other. The results showed that the use of assessment methods in CE projects has increased in the recent years as well that an LCA was by far the most used assessment method and waste management the most common aspect of CE in CI.
