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.

Governments and private investors are increasingly becoming aware of the marketing power and the importance of seismic safety of old cores of their cities. Hereby the interest in preserving the original look and often even the original, but improved construction of the buildings becomes imperative and a demanding task for engineers and project managers. The main goal of project management is controlling the outcome of a project through control of elements like quality of the final product, costs and time, whereas practice shows that these types of projects very often overrun cost and time limits. Therefore these are the main research questions: Can construction projects on strengthening and preserving existing buildings be successfully governed with existing risk management tools? If not, how can we improve the existing risk management tools?In this paper development of a new risk breakdown structure for construction projects on existing and historical buildings is presented. The risk breakdown structure is developed based on previous project experiences and in collaboration with a series of experts

The potential uses of 3D scan data in the construction industry have been extensively researched in the last 20 years, with many benefits over traditional methods proclaimed by researchers. However, despite their advocated benefits, their implementation in actual construction sites remains low. This research aims to discover the potential uses of 3D scan data for construction management purposes and the limitations and barriers to their implementation and widespread adoption. Previous research into the topic was analysed to discover what technologies were used for generating 3D scan data, for what purpose and what issues were identified. These discoveries were then used to specify the potential uses of 3D scan data for, primarily, progress monitoring and quality control, which were then cross-referenced with all known limitations and barriers from the literature and the researchers’ own experience. Research has shown that, currently, there are numerous issues with both the capabilities of current technical solutions and with the construction industry’s readiness, which hinder mass adoption. Potential for breakthroughs, fortunately, does exist; however, greater impetus from the construction industry is needed to drive forward the demand for better technical solutions, which would resolve current issues and lead to the widespread adoption of 3D scan data for construction management-related uses.

If sustainable development goals are to be achieved, it is necessary to consider refurbishment of architectural heritage buildings as well! As just 1% of buildings in the European Union have been built since 2006, it is essential to turn towards refurbishment of existing buildings if goals of sustainable development are to be achieved. Therefore, this article explores the ways in which sustainable development in construction is encouraged and achieved, especially concentrating on architectural heritage buildings. The idea of sustainable development revolves solely around carbon emissions, and therefore, historic buildings in Europe face the key issue of sustainability. Recently, there has been an increasing interest in reusing existing buildings through refurbishment and adaptive reuse where possible, as building reuse should offer environmental savings over demolition and new construction. In addition, despite popular belief, older buildings are capable of adapting to the new energy efficiency norms. This study explores the possibilities of encouraging complete refurbishment (including both sustainable renovation and strengthening) of historical buildings by exploring incentives used in Europe, the USA, Canada and New Zealand. Based on the literature review and best practices, the article concludes with recommendations on how to increase the positive investment flow of private capital into architectural heritage buildings, thus ensuring both preservation of heritage and achievement of sustainable development goals. The findings help both the user of the initiative on gaining insight into the intervention process that can be expected, as well as the local and regional governments interested in boosting adaptive reuse and refurbishment of existing buildings in order to achieve sustainable development goals.

Risk governance is mostly viewed through the lens of disaster or emergency management departments, agencies, or organizations. Visible in times of crises, risk governance is rarely seen as part of everyday public or private functions such as planning, social welfare, investments, or fiscal responsibilities. This paper emphasizes the importance of disaster risk governance in disaster risk management activities on the example of the post-disaster recovery of Croatia after a series of strong seismic events in mainland Croatia. The analysis is made based on a thorough review of national documents of Croatia and other selected countries overlapped with the national journals reporting on the situation from the affected areas. In accordance with the authors’ opinion, the necessary elements of disaster risk governance are clearly stated through the four Sendai framework priorities, and this statement is supported by the facts from the case study. Without either the political will or the enabling surrounding the disaster, risk management is next to impossible. The Croatian case study emphasizes the importance of disaster risk governance, showcasing the adaptation process for the post-disaster recovery process to start.
