Abstract In practice, sealed joints in the construction industry are very often exposed to adverse climatic influences. One of these climatic influences is the effect of water, for example in the form of rain or humidity. This article is therefore devoted to the sealing of joints of problematic base materials, which are then exposed to the effects of water and subsequently tested according to the recommended test standards. For this research, a problematic substrate based on cement is selected, and glass cement is specifically chosen for its shortcomings. The main disadvantage of this material is the existence of small particles on its surface, which due to their insufficient wettability disrupt the adhesion of both the primer and subsequently the sealant to this substrate and thus significantly reduce the quality of the sealed joint. Furthermore, representatives of several types of sealants and primers recommended for them available on the Czech market are selected for this experiment. Test specimens are made using glass cement plates treated with the appropriate primer and the sealant. These test specimens are then the goal of a test procedure to verify the properties of the sealed joint of the problematic material and the selected primer and sealant that is exposed to the water element. The results of these tests are then presented in the article.

Prefabricated power support structure foundations are made in prefabrication plants where concrete is laid in layers in moulds. The quality of the prefabricated units depends mainly on proper concrete mixture compaction, which is usually effected by means of immersion vibrators. It happens that when the vibrator is withdrawn too quickly, defects, in the form of, e.g., air voids and zones of insufficiently vibrated concrete, appear. Modern non-destructive acoustic techniques, which in recent years have been increasingly commonly used in the construction industry, are highly suitable for testing concrete elements, particularly prefabricated concrete units. The non-destructive impact-echo technique is particularly useful for determining defect location depth and for locating defective areas.

The article examines the organizational basis of modeling entrepreneurial activities in the hospitality industry based on the use of indicators of cadastral assessment of land. The analysis of practical aspects of updating the results of cadastral assessment of lands of settlements of Cherkassy region has been carried out. It is stated that the cadastral assessment should take into account market situations and trends as much as possible. For the territories of localities the term of actualization in the context of revaluation should be minimum and economically justified. It is designated that the updating of the results of the state cadastral assessment of land requires significant modernization aimed at improving the quality of land assessment work and adequate replenishment of budgets at all levels. The mechanism and features of performance of works on actualization of the state cadastral estimation of the lands of settlements in the territory of Cherkassy region have been analyzed. As a result of the study, it has been found that the main disadvantage of modeling the cadastral assessment of land settlements is: the duration of time intervals between rounds of revaluation, which causes rapid aging of information. The reason for this case is related with the financial support of the works and their scale. Mechanisms for prompt updating of information on the value of land for entrepreneurial activities in the hospitality industry in Cherkassy region have been proposed. The considered method of determining the normative monetary valuation of land takes into account the most important indicators of this industry and is practically significant in collecting information and calculating all indicators in conducting cadastral valuation of land for entrepreneurial activities in the hospitality industry of Cherkassy region. The practical significance of the study is to assess the cadastral condition of land and calculate the specific cadastral value of the city of Uman, as the territory where the hospitality industry is the most developed in Cherkassy region. Due to the clarification of the specific indicator of cadastral value, the price of one square meter of such objects will increase which will allow to proportionally increase the tax component and increase the profitability of budgets at the cluster level

Synthesis Approach

A meta-synthesis approach was used to identify, synthesize, and categorize appropriately factors in the literature that contribute to design documentation quality. The categories include factors on quality attributes, quality indicators, and quality-influencing factors. Findings indicate that the quality of design documentation in practice is unsatisfactory, therefore, there is a need for collaboration between the owner, designers, and end-users to improve design documentation quality. The results offer pragmatic data on design documentation quality in the construction industry between the years 1992 and 2019. However, further research on the significant impacts of poor-quality design documentation on construction projects is recommended.

Revolutionary changes in society are linked to digital technologies and affect all areas of social life, not excluding construction industry. This requires not only knowledge reform, but above all skills reform. The current demand of practice is to increase the knowledge and competences of graduates of civil engineering faculties in the field of introduction and use of digital technologies in the process of planning, implementation, and maintenance of buildings, as well as to support the skills development of civil engineers in teamwork while using BIM technologies. The presented, currently implemented project contributes to meeting the above-described Practice Needs. The expected direct impact of the project is to increase the competitiveness, employability, and quality of life of graduates entering practice.

Abstract This study was conducted to assess the effect of water quality of the Ogun River on the haematological indices of the African catfish Clarias gariepinus. Samples of water and Clarias gariepinus were collected from Ogun River (Station I, Opeji and Station II, Lafenwa) to determine and compare effects of possible differences in water quality on haematological parameters of Clarias gariepinus. The results demonstrate that higher index values were recorded at station II than Station I for almost all the physicochemical parameters and only sulphate values from Stations I and II were statistically significant (P < 0.05).

<p>With the rapid development of social economy, the demand for new energy is also increasing, and then the problem of large consumption also has a negative impact on the development of the construction industry. Under the concept of green building, the design and construction units pay more attention to energy conservation and environmental protection, so they actively use photovoltaic new energy in the field of electrical energy conservation of construction projects, so as to improve people's quality of life. Starting from the principles and characteristics of building electrical energy conservation, this paper discusses the methods of building electrical energy conservation, and analyzes how to use photovoltaic new energy in the field of building electrical energy conservation, hoping to better practice the concept of energy conservation.</p>

The article deals with the issue of state regulation over the construction products industry. Analysis resulted in the identification of two main forms of regulation: tariff and non-tariff regulation. Global practices show the effectiveness of non-tariff regulation in the construction industry. Being a WTO member, Ukraine has to implement the legal framework of non-tariff regulation, in regards to those aspects contributing to compliance with the rating and standards of the European Union to ensure the quality of products. The main objective of non-tariff market regulation is to ensure the quality of finished products, environmental protection, health and safety of life. The national system of regulation, including technical rate-setting of the construction products manufacturing must comply with the international documents ratified by Ukraine. The article analyzes the domestic legal framework and proposes an algorithm for designing a national system of non-tariff regulation in accordance with international rules and standards.
