After Russia’s aggressive invasion of Ukraine and devastating military action, Ukraine needs significant construction work to rebuild its war-ravaged infrastructure. Several Latvian construction companies have expressed their desire to participate in these construction projects on the territory of Ukraine, which has suffered from military damage. In order to implement full-fledged construction projects, Latvian businessmen need to make adjustments and make a comparison between the construction regulations of the two countries. In Latvia, construction issues are regulated by the Construction Law and related regulatory acts. On the other hand, in Ukraine, construction issues are regulated by several laws, which are included in the national and local legislation systems, as well as various construction regulatory acts, which are not legally binding but are widely used in practice. Compared to the production of the industrial sector, the production of the construction sector has several important differences. In the construction industry, technical characteristics are important, for example, geographical locations and natural conditions must be considered, as well as the client’s specific requirements regarding the object to be built. In construction, production is very specific, and the process is characterized by the sequence of construction works and the connection between different stages of construction, as well as the need for material supply and labour organization. Construction projects have complex legal procedures, and the maintenance and sustainable use of construction sites is an important aspect that distinguishes the construction industry. Construction is often project-based, where short- and long-term planning and budgeting are critical. Financing sources and return on investment in construction projects are particularly sensitive issues. Construction projects require cooperation between various stakeholders, including entrepreneurs, workers, customers and the public. Occupational safety and working conditions are particularly important in this industry. Construction affects the environment, so it is important to consider aspects of environmental protection and sustainability, as well as comply with relevant regulatory standards and requirements. The authors of the research conclude that each group of characteristics of construction products includes its own internal evaluation sub-criteria. These subcriteria help to evaluate and analyse the characteristics of specific construction products. As a result of the research, groups of criteria will be developed, which will be applicable both in Latvia and Ukraine in the future, because each of the subcriteria or evaluations of groups of features helps to more accurately understand and evaluate the aspects of a given construction project or production. This is very important to ensure a successful construction process and product quality.
