“…The identification of risks associated with the use of glass elements should be carried out primarily during the design and installation phase. Integrated management systems of building processes may play a vital role in the matter in question (Sobczyk et al, 2018). Inspections of glass elements in the course of their use are also crucial.…”

Recent years have shown increased interest in the use of glass structures in the construction industry. Investors value qualities such as aesthetics and the good environmental resistance of glass. It has become commonplace to use glass not only to construct façades, but also in horizontal partitions (floors, building coverings ) and in such elements as protective canopies, passageway screens or fire barriers. Such extensive use of this building material has been made possible by the development of technology for manufacturing glass with improved strength properties, in particular, toughened and laminated glass. However, glass has some disadvantages as a building material – first of all, low tensile strength, impact strength and point load compressive strength. The use of glass with improved strength properties minimises these defects to a considerable extent. Nevertheless, it sometimes happens that glass structures crack or lose their aesthetic value. This results from errors made during the design stage as well as during the construction work on the structure. Based on an “in situ” study and the literature on the subject, the article identifies risks associated with the use of glass elements, in addition to analysing their causes and possible effects. Examples of real elements in the course of their use are provided in order to illustrate the factors under analysis. Moreover, the article includes recommendations linked to the safe usage of glass in the structure when discussed against the background of assembly errors.

“…Increasing the number of air exchanges in rooms will reduce the level of CO2 pollution and eliminate the phenomenon of a sick building (Kapalo et al 2014). To maintain proper environmental conditions during the operation of the building, it would be good to use tools based on BIM technology (Sobczyk et al, 2018). :49:00 8:29:00 9:09:00 9:49:00 10:29:00 11:09:00 11:49:00 12:29:00 13:09:00 13:49:00 14:29:00 15:09:00 15:49:00 16:29:00 17:09:00 17:49:00 18:29:00 19:09:00 19:49:00 20:29:00 21:09:00 21:49:00 22:29:00 23:09:00 23:49:00 0:29:00 1:09:00 1:49:00 2:29:00 3:09:00 3:49:00 4:29:00 5:09:00 5:49:00 6:29:00 7:09:00 7:49:00 8:29:00 9:09:00 9:49:00…”

Safety of use of the buildings refers i.a. to ensuring appropriate hygienic and sanitary conditions and also health conditions. According to the EU Directive on the energy performance of buildings, there is a need to define the conditions for the classification of objects in terms of indoor microclimate requirements. Evaluating the quality of the interior environment in buildings and specifying the requirements of people staying in them, first of all the values of thermal microclimate parameters and air quality should be taken into account. Long-term influence of disadvantageous of environmental conditions may cause or exacerbate many symptoms associated with abnormal functioning of the organism and lead to the weakness or illness. This phenomenon is called sick building syndrome, and the symptoms of the syndrome such as eyes and respiratory tract irritation, malaise, dizziness and headache or fatigue are linked to time spent in the building. The article presents the results of research on the condition of the interior environment in educational buildings, identifies factors affecting the formation of environmental conditions in the rooms and shows the influence of the interiors environment in buildings on the human body. The relationships between the basic parameters of the interior microclimate and the state of feeling satisfaction with the environmental conditions that surrounds the human are tracked. It was found that in many cases commonly used gravitational ventilation is not able to ensure the proper conditions of the interior microclimate, and the concentrations of carbon dioxide recorded in the tested rooms exceeded the applicable standards. Keywords: interior microclimate, air quality, hygienic and sanitary conditions, sick building syndrome, safety of use of the buildings.

“…The fitness function selection is crucial, as it directly affects the convergence speed of the genetic algorithm and the ability to find the optimal solution. Solving the objective function directly into the fitness function is a simple and intuitive process, and if the objective function is the minimum problem, then: (11) In Eq. ( 11), is the maximum estimate of .…”

“…Budget and cost management focus on the construction segment, an important cost segment in the building construction process [9][10][11].Executing cost budgets for construction projects, controlling the transfer and use of funds, and securing sufficient funds for the project are essential to achieve the basic control objectives of capital operations [12][13]. Financing and planning are crucial aspects of engineering projects that significantly impact project cost budgeting and cost management.…”

In this paper, based on the matrix model to count the number of elements and judge the symmetry of matrix elements, the nearest neighbor space in high-dimensional space is converted into a symmetry matrix. The boundary extraction is discretized and iterated repeatedly until the fitness satisfies the final condition. The genetic algorithm finds the optimal solution, which is transformed into the fitness function, and the system reliability constraints are processed to solve the cost control problem. According to the results, the cost control cost of the construction project is reduced by 10% based on the matrix model. It shows that the proposed model can promptly solve the existing project cost over-budget situation, which makes the enterprise obtain more economic benefits and enhance the market’s competitiveness.
