Healthy residential buildings represent the future of construction concerned with the environment, which is increasingly emphasized. This is directly related to the research and development of environmentally friendly building materials, which on the one hand meet the specific requirements of the builder, and on the other hand do not harm the environment. The research is based on the possibility of achieving increased variability in healthy residential buildings via the customization of recycled polyvinyl butyral using smart technologies for sustainable design. This study has two sub-goals; the first and foremost is the development and adaptation of recycled polyvinyl butyral to increase the elevation of the healthy residential buildings. The second objective is to design a methodology, and create databases and intelligent designs, via knowledge and building information modeling (BIM) technologies. In future research, data on environmental materials (such as the abovementioned recycled polyvinyl butyral) should be implemented in the knowledge databases that will be methodically described in our second sub-target.

Sustainability in construction can be perceived across several areas. Sustainable supply chain and cost management are two of them. If this issue is addressed in the management of sustainable building materials and waste management in the implementation of construction projects, in the context of sustainability, cost management and supply chain management affect the overall success of construction projects. The aspect of sustainability is based on reducing costs and, thus, also material items. At the same time, there is a focus on the use of waste or its economic and ecological disposal. Finally, sustainability means the setting up of logistics processes. Information and communication technologies can significantly help supply chain and cost management and construction waste management. This means, on the one hand, minimizing the consumption of materials and, thus, also costs, and on the other hand, by optimally setting up the supply chain and logistics, using materials and funds efficiently and optimizing waste management. The research discusses the impact of information and communication technology on a sustainable chain and cost management on various construction projects in Slovakia. The research aims to analyze information and communication technology’s influence on a sustainable chain and cost savings of waste in construction projects. The main research hypothesis is based on the assumption that information and communication technology positively affect sustainable chain and cost management of waste in the Slovak construction industry. Data collection was performed through an online questionnaire. It contained three primary areas of data collection: The first part contained questions about the characteristics of the research sample. The second concerned the use of information and communication technologies and the third pertained to their impact on sustainability and reducing the costs of the waste management process in construction. The research samples consisted primarily of foreign companies operating in Slovakia. From the point of view of the participants in the construction project, these were developers, contractors, sub-contractors and designers. The Kruskal–Wallis test was used to confirm this hypothesis. The research provides an overview of information and communication technologies and their impact on supply chain and cost management of waste in construction.

Life cycle cost management is an integral part of buildings construction. The life cycle cost approach can be considered an objective approach because it considers all life cycles of buildings. Information and communication technology is one of the critical factors for the success of construction projects. Several studies point to the importance of information and communication technology use in life cycle cost management. Generally, information and communication technology can be helpful in the cost management process of buildings. However, few implementation factors of information and communication technology are used in the life cycle cost management of buildings. The research assumes that the most critical implementation factor is the investment cost for information and communication technologies used in cost management during the life cycle. The relative importance index method was used to evaluate and quantify the final rank of implementation factors. The Kruskal–Wallis test was used to confirm or reject research results that were statistically significant.

The issue of sustainability has long been the subject of interest in architecture engineering and the construction sector. All three aspects of sustainability—economic, environmental, and social—can be affected through appropriate construction waste management. Construction and demolition waste (CDW) is one of the largest worldwide waste streams, therefore, it is given great attention by all stakeholders (investors, contractors, authorities, etc.). Research studies show that one of the main barriers to insufficient CDW recovery is inadequate policies and legal frameworks to manage CDW. It is also one of European Union’s (EU) environmental priorities. The aim of the article was to confirm the economic potential of construction and demolition waste audit processing through a case study. A pre-demolition waste audit was processed for an unused shopping center building in the town Snina in Slovakia. Subsequently, a comparison of economic parameters (waste disposal costs and transport costs) of the recommended CDW management was performed. This comparison confirmed the economic benefits of environmentally friendly construction waste management methods according to the waste audit results, which would also increase the sustainability of construction projects. Additionally, the cost parameters of selected waste disposal methods could be another dimension of building information modeling.

Changes in riverine hydrography and reduced aquifer recharge due to projected climate changes in arid and semi-arid regions are the main issues of water supply, especially in the Nile Delta, Egypt. Continuous degradation results from reduced Nile water flow, poor management of groundwater extraction, and human activities throughout the Nile’s course and drainage channels. Contamination of this water with heavy metals and dissolved organic solids reduces the quality of this water, which increases the price of treatment. River Bank Filtration (RBF) is a water treatment technology used for improving the quality of drinking water taken from polluted rivers where abstraction wells are installed on the banks. This study was applied to the RBF site at Embaba, Nile Delta, Egypt using the numerical code MT3D. The study was simulated and calibrated for the current situation and number of scenarios to investigate the effect of climatic changes on RBF sustainability. Four scenarios were simulated to identify and estimate the RBF portion and the total water travel time from the river to the wells. The first scenario involves a reduction in river stages, the second a decrease in aquifer recharge, the third a combination of the first two scenarios, and the fourth scenario combines scenarios 1, 2, and 3. The results indicate that the RBF portion decreased from 67.42% in the base case to 35.46% and 64.99% with a reduction in river stage by 75% from the base case and a decrease in aquifer recharge from 182.50 (base case) to 50 mm per year, respectively. Moreover, the RBF portion increased to reach 87.75% with a reduction in the General Head Boundary of 75% from the base case, while the combination of the three scenarios decreased the RBF portion to 67.24%. Finally, the water supply systems in arid and semi-arid regions should be extended by installing and operating RBF facilities to manage the negative effects of climatic change through reduction in river stages and aquifer recharge, and increasing abstraction due to overpopulation.

Accurate estimation of evapotranspiration is one of the main aspects of water management. In this study, the capabilities of soft computing techniques for estimating daily evapotranspiration in Košice (Slovakia) were investigated. Daily solar radiation (SR), relative humidity (RH), air temperature (T), and wind speed (U) were the meteorological variables used for modeling. Based on the data, different combinations of multilayer perceptron (MLP), support vector regression (SVR), multilinear regression (MLR) models were generated. Model results are compared with each other and with the Hargreaves-Samani, Ritchie, and Turc empirical equations using three statistical criteria, namely mean square error (MSE), mean absolute relative error (MAE), and determination coefficient (R2). Of the empirical formulas applied, the Hargreaves-Samani equation gave the most compatible results with the Penman FAO 56 equation. Error percentage histograms were generated as a reference criterion. Model results show that the MLP model performs better than the other soft computing techniques used.

Sustainability in civil engineering industry represents space for the subject of discussions and extensive research opportunities. On the other hand, this represents worldwide pressure to explore this area. Sustainability in the context of Building Information Modelling technology is also often a controversial topic. BIM technology brings many benefits. Exploring these technologies from the field of sustainability and environmental aspects is more than desirable in the light of global developments in this field. The aim of the research was to point out and propose a structure of environmental parameters based on the acquired knowledge, which will be incorporated into the emerging database of elements - information models. The paper presents a proposal for the structure of the database of structural elements taking into account cost parameters, time parameters, environmental parameters and life parameters, points out the main advantages of the proposed database and defines the aims of further research. The aim of the paper was to analyse the current state and possibilities of implication of certification systems for sustainable construction and describe the current state and impact of BIM implication on selected aspects by survey.

Progressive technologies and practices are shifting the possibilities of building design and improving work efficiency. Constantly changing site conditions require different procedures and designs that take into account these changing conditions, whether it is a design solution, a change in environmental conditions, or just sustainability factors. Adaptive building design offers opportunities to cope with changing factors to achieve the ähighest possible level of building quality. This case study deals with the topic of adaptive formwork design for building renovation, taking into account sustainability. The aim of the article is an investigation and demonstration of the building information modeling (BIM) environment used for the adaptive design of formwork elements for the building renovation in the context of sustainability. The object of the case study is a building in the center of Kosice, Slovakia. The BIM environment allows prompt and correct adaptation of the formwork design to changing lighting conditions, ventilation, heating and temperature during the design of the building.

Intensive agriculture requires increasing application of fertilizers in order to sustain food production. Improper use of these substances in combination with increasing seawater intrusion results in long-term and nonpoint soil and groundwater contamination. In this work, a 3-D groundwater and solute transport numerical model was created to simulate the effect of excessive fertilizers application along the Bahr El Baqar drain system, in the eastern Nile Delta, Egypt. The geotechnical properties of the soils, hydrologic parameters, and unconfined compressive strength were determined at different sites and used as input parameters for the model. Model results showed that silty clay soils are able to contain the contaminations and preserve the groundwater quality. Nevertheless, sandy soils primarily located at the beginning of the Bahr El Baqar drain allow leakage of fertilizers to the groundwater. Thus, fertilizer application should be properly managed in the top sandy layers to protect the groundwater and soil, as increasing aquifer by excess irrigation water increased the groundwater contamination in confined layers due to the high value of cumulative salt for the current situation while the unconfined zone decreased groundwater and soil contamination. A mass transport 3-D multi-species (MT3D) model was set to identify the optimal measure to tackle soil and groundwater contamination along the Bahr El-Baqar drain system. A potential increase of the abstraction rates in the study area has a positive impact in reducing the transfer of fertilizer contamination to groundwater while it has a negative impact for soil contamination. The scenario analysis further indicated that the installation of a drainage network decreases the groundwater and soil contamination. Both solutions are potentially effective for protection against nonpoint contamination along the Bahr El Baqar drain system. However, a more sustainable management approach of fertilizer application is needed to adequately protect the receptors located further downstream in the Nile Delta.

The construction purposes of carbonate rocks are considered a major aspect of using these bedrocks based on their mechanical behavior. Accordingly, the physical and mechanical characterization of Middle Eocene Limestone bedrock in the new urban area at the 15th May City, Egypt was studied to assess the suitability of the carbonate rocks for construction. This study has been carried out to investigate the effect of petrographic characteristics on mechanical properties. To achieve this objective, the intact 30 rock core samples from 15 boreholes were selected at different depths. Based on study of the selected samples in thin sections, the limestone in the area was classified as lime-mudstone, wackestone, and grainstone. Additionally, the uniaxial compressive strength (UCS) and Schmidt Rebound Hammer (Rn) were determined to detect the mechanical properties of the limestone bedrock. The measured parameters (UCS and Rn) demonstrated a high direct relationship with mudstone and a poor direct relationship with dolomite and high negative correlation with wackestone and grainstone. Therefore, the Middle Eocene Limestone bedrock is more durable and has medium-strength, which made it suitable for constructions. Regression analysis was performed to find out some linear relationship between mechanical properties (UCS) with petrographic characteristics. The study reveals significant positive correlation between UCS and Rn with mudstone in accordance higher values of regression coefficient (R2 = 0.91 and R2 = 0.036), and an inverse relationship of Rn with dolomite % (R2 = 0.89 and R2 = 0.02), respectively. Consequently, the strong confidence on the mechanical parameters opens the way for engineers to predict the mechanical parameters that are required for engineering properties of limestone for the urban expansion.

Waterways are usually contaminated with wastes from industrial, domestic or irrigation sectors. Organizations in charge have adopted solutions to eliminate this problem; however, the adopted solutions contribute indirectly to modifying canal morphology during maintenance. These are examples of anthropogenic activity, as well as randomly implemented dredging, which expand the canal cross-sections. Egypt is a country which depends on surface irrigation through a huge network of canals. The majority of canals in Egypt are subject to anthropogenic activity which affects their efficiency. This study aims to assess the impact of conjugated instances of anthropogenic activity and dredging on canal morphology and capacity. Five canals were selected in the current study in the Nile Delta, Egypt. These canals are highly affected by two associated factors: anthropogenic activity by users and dredging by the government. The study also aims to determine the effects of a newly adopted policy for saving surface water through restoration of the canals’ originally designed cross-sections. The results showed a clear change in canal morphology, which has increased the volume of water in the affected canals. In some cases, the volume of water has increased by 59%, which could have negative consequences for Egypt’s water resources. Sustainable management of water resources in Egypt requires saving each water droplet, and canal rehabilitation is expected to save about 6.56 million m3/year by the year 2022.

Small unmanned aerial vehicles (UAVs), commonly called drones, are gaining popularity not only among the general public and consumers but also among professionals working in the AEC (architecture, engineering, and construction) industry. One way in which drones are proving to be a useful tool in architecture is through as-built surveying. Due to their small size and relative ease of maneuverability, drones make an easy task of accessing difficult-to-reach places. Airplanes are not able to fly too close to the ground, and therefore, the use of unmanned aerial vehicle in connection with the photogrammetry principles for digital mapping of building objects provides an effective solution. The main objective of this contribution is to describe how effectively to use unmanned aerial vehicle in the area of digital as-built mapping of existing buildings. As a reference building, the Faculty of Civil Engineering, located in Kosice, Slovakia, was chosen. This building is represented in the article as a reference object on which data collection is described as well as data processing with a specific hardware and software solution. The result of aerial mapping is a point cloud that serves as a template for processing of as-built documentation in the form of 2D layouts or 3D models, and the contribution also points to the possibility of linking aerial imagery to terrestrial laser scanning.

Erosion phenomena are the result of complicated natural processes. The determination of their course, their mathematical expression, and predicting erosion phenomena of certain intensities is an important hydrological problem. To obtain a solution, it is necessary to evaluate the erosion factors in detail, which act by the origin and course of erosion processes, to analyse their influences, and to apply correct conclusions to their complex activity on this basis. Dimensional analysis is a conceptual tool often applied in engineering to understand physical situations involving a mix of different kinds of physical quantities. It is routinely used by physical scientists and engineers to check the plausibility of derived equations and computations. It is also used to form reasonable hypotheses about complex physical situations that can be tested by experiment or by more developed theories of the phenomena. In this paper, the dimensional analysis is used for the modelling of erosion and transport processes.

Several studies have reported that the construction of the Grand Ethiopian Renaissance Dam (GERD) could have severe effects on the water resources in downstream countries, especially Egypt. These effects include changes in surface water level, groundwater levels in shallow and deep aquifers, saltwater intrusion, and increases in soil salinity, which could affect crop yields. This paper assesses the potential impacts of the GERD on the Nile Delta, Egypt. It includes the effects of reducing surface water levels (SWL) and changing the crop patterns at the groundwater levels (GWL), in addition to the effect of cultivating crops that consume less water on soil salinity. A pilot area is selected in the east of the Nile Delta for the assessment. The results of the study revealed that GWL is directly proportional to SWL. Comparing the case study of 2012, when SWL was reduced by 50%, the GWL decreased from 5.0 m to 2.0 m. After adjustment, the crop patterns from rice to other crops decreased the GWL to 1.30 m. Additionally, the results showed that there is a significant relationship between soil salinity and crop patterns. Soil salinity increased during the cultivation of the Delta with non-rice crops, such as grapes. Salinity increased from 0.45 S/m after 10 years of simulation to 0.48 S/m. This estimation highlights the undesirable effects of the GERD on Egypt’s water resources, soil salinity, crop yields, and national income.

An unmanned aerial vehicle (UAVs), also known as drone technology, is used for different types of application in the civil engineering. Drones as a tools that increase communication between construction participants, improves site safety, uses topographic measurements of large areas, with using principles of aerial photogrammetry is possible to create buildings aerial surveying, bridges, roads, highways, saves project time and costs, etc. The use of UAVs in the civil engineering can brings many benefits; creating real-time aerial images from the building objects, overviews reveal assets and challenges, as well as the broad lay of the land, operators can share the imaging with personnel on site, in headquarters and with sub-contractors, planners can meet virtually to discuss project timing, equipment needs and challenges presented by the terrain. The aim of this contribution is to create a general overview of the use of UAVs in the civil engineering. The contribution also contains types of UAVs used for construction purposes, their advantages and also disadvantages.

Today, more and more attention is dealt with environmental issues and sustainable construction in society. The construction industry is demanded on the amount of energy consumed and greenhouse gas emissions. Using sustainable construction is a fundamental concern for society to lead to environmentally sustainable future. Sustainability contains social, economic and environmental aspects. In last years, we have seen an increase in innovation in the construction industry sector. Support in buildings construction´s innovation is one of the major ways to realization, manage and operate the building’s life cycle. Making these processes more efficient leads to the promotion of sustainable construction. This article is pointing out the different aspects of sustainability and provides an overview of innovative technologies used in the construction sector and focuses on their contribution to promoting sustainable construction. Special attention is dealt with technology of building information modelling, especially its benefits and tools to support building sustainability.
