Prediction of Concrete Constituents’ Behavior Using Internet of Things (IoT)

Due to the challenges of providing constant observation and control of the curing environment, the effectiveness of the conventional concrete process on site is poor. This causes a significant difference in the curing regimes encountered by various concrete pours. Yet, the potential of Internet of things (IoT) technologies has not yet been exploited in this context. To improve concrete practice, technologies have been harnessed that reduce human participation and enable more rigorous management of the ambient variables impacting curing. The interior temperature of concrete may be directly measured in real time and continuously monitored by a management system for in-place concrete using an all-in-one wireless sensor network (WSN) during the initial phases of curing. Without considering the wiring at the building site, the algorithm may also provide a well-informed choice about the removal of the formworks. To monitor and regulate the moisture content of hardening concrete to the levels necessary for high-quality hardened concrete, this research study looked at an IoT-based concrete curing control system based on sensor technologies. The effectiveness of this IoT-based technique was compared to the effectiveness of conventional curing procedures based on on-site trials. According to the findings, the system developed beats the conventional method in terms of both the effectiveness of concrete curing and the amount of time required for supervision.

From sacred to secular: A study of the transformation in spatial functions of modern Confucian temples (1906–1937)

In traditional China, Confucian temples (孔廟 Kongmiao) were sacred spaces with the main functions of offering sacrifices. In the late Qing and early Republican era, even though the sacrificial functions of Confucian temples were extended through the changing regimes and systems, their sacred nature was weakened. During the mid- to late-period of the Beijing government, as the degree to which those in power venerated and worshiped Confucius weakened and modernization advanced, the tendency toward the functional secularization of Confucian temples became increasingly apparent. This was centrally manifested as the formalization of sacrificial functions and assumption of social and education functions. After the establishment of the national government in Nanjing, out of the need for nation-state building, Confucian temples took on multiple functions of modern commemoration, political propaganda, school building, and cultural and historical site building. As different entities had different expectations for the roles that Confucian temples would play during different periods, their actual functions clearly deviated from and missed those stipulated by official documents. Many difficult to reconcile appeals for reform or continuation, for development or conservation joined together in the space of Confucian temples, making it so their spaces could not develop along a linear mode of “traditional-modern.” The course of Confucian temples “turning from sacred to secular” reflects not only the difficulty of transforming Confucianism but also the complex political-cultural ecology of modern China.

Assessing noise impacts from light aircraft

Typically in Australia, aircraft noise is assessed against the Building Site Acceptability criteria set out in Australian Standard 2021:2015 Acoustics-Aircraft noise intrusion-Building siting and construction (AS 2021), which uses the Australian Noise Exposure Forecast (ANEF) system for land use planning around airports. However, the ANEF system and AS 2021 are not intended to present information about potential impacts from aircraft noise (such as from light aircraft operations) that may be experienced within the community and are considered deficient as a useful tool for describing aircraft noise to potential noise sensitive receivers. This paper discusses a methodology that may be used to better subjectively assess the environmental noise impacts from light aircraft taking into account the issues related to light aircraft operations, such as the level, duration and tonal content of noise from the aircraft. The paper will focus on observations made on a recent study of noise monitoring undertaken in March 2023 for light aircraft trial flights in Canberra ACT.

Representation, Race and Empire: a Postcolonial Analysis of the New York Global History Regents exam

ABSTRACT Postcolonial studies have long identified history curriculum as a site of empire building. High stakes exams like the Global History Regents Exam in New York (NYGHR) undoubtedly impact curriculum but have yet to be examined through a postcolonial lens. This study evaluates to what extent, if at all, the NYGHR perpetuates eurocentrism as defined by four concepts from the literature: numerical representation, replacement, tokenism and narrative erasure. Through both qualitative and quantitative analysis, the study finds the exam to be eurocentric both in its numerial underrepresentation of the global south, and in its replacement and ommission of global south achievement, its overuse of tokenism, and its flagrant narrative erasure of the violence of colonialism. The study posits implications and next steps for students, practitioners and future research on how to build inclusive, student driven global history curricula

Seismic design and evaluation of controlled rocking outrigger core wall (CROCW) system using equivalent energy design procedure (EEDP)

In this paper, a novel earthquake resilient reinforced concrete core wall system named the controlled rocking outrigger core wall (CROCW) system is proposed. The CROCW consists of two high-performance seismic force resisting systems along its two principal axes. Along one principal axis is the controlled outriggered rocking wall (CORW), where an outrigger is situated at the roof and controlled rocking at the base. Dampers are incorporated within the outrigger and the rocking base to allow CORW to provide stable energy dissipation during earthquake excitation. Along the other principal axis is the self-centering coupled wall (SCCW). In the SCCW system, the self-centering friction dampers are incorporated within the coupling beams to dissipate the earthquake energy, while the base is designed to rock. The proposed CROCW system can be designed using the novel equivalent energy design procedure (EEDP). Four prototype buildings (two different building heights and two different building sites) were designed using the EEDP presented in this paper. The detailed nonlinear time history analysis was conducted to assess the performance of CROCW system. The results demonstrate that the CROCW system can be efficiently designed using the EEDP procedure to achieve a superior performance and low damage response at multiple levels of earthquake shaking intensities.

Abstract Adrian Duncan’s second novel A Sabbatical in Leipzig (2020) marks a departure from ‘typical’ Irish topics such as national identity and religion. This he shares with a range of contemporary Irish authors, particularly those writing in the aftermath of the Celtic-Tiger years. The novel’s focus on architecture and engineering, which also looms large in Duncan’s other novels Love Notes from a German Building Site and The Geometer Lobachevsky, is unique, as it leads to unusual reflections on the nature of material culture. This original approach to the novel form should be considered as part of the current international trend to integrate theoretical reflections on a wide range of topics, thus negotiating contemporary cultures of knowledge. The novel’s international outlook moves away from ‘typical’ Irish topics of national identity and religion shared by a wider range of contemporary Irish authors, particularly those writing in the aftermath of the Celtic-Tiger years. The novel is thus also a reflection on the collapse of old systems, be they political, social, or epistemological, and the existential uncertainty created by their demise. I argue in my paper that Duncan’s novel addresses questions of knowledge formation that bear a striking resemblance to the Romantic novel as an open and generically hybrid form. I read it in a wider context as part of an ongoing experience of crisis: my overall thesis aims at describing the contemporary tendency to include abstract reflections that interrupt the narrative sequence as an expression of a fundamental crisis of knowledge. Today’s mediascape represents the contemporary world in a state of severe emergency, whose symptoms, be they climate change, the rise of nationalism and the far right, ultimately lead to a fundamental experience of contingency. Novels like Duncan’s can thus be seen as an expression of the crisis of the contemporary media ecology of knowledge.

An Investigation into Implementation of Project Quality Management Plan on Building Projects in Awka, Anambra State, Nigeria

The study is aimed at an investigating into the implementation of Project Quality Management Plan on Building Projects in Awka Anambra State, Nigeria, with a view to establishing the level of awareness and advocate the benefits associated with implementation of Quality Management Plan on building projects. This study adopted the use of structured questionnaires and literature reviews. The sample size was 250 building site managers, to elicit relevant data, and were analyzed by using simple percentage and Principal Component Analysis (PCA), using SPSS 23 software. The result indicate that construction practitioners are aware of PQMP in Awka, Anambra State and often apply the document to all building projects. The top benefits of implementing project quality management plan, are that it increases project efficiency and saves cost. At the end of the work, I recommend that Anambra State government should domesticate the national building code. Builders should be given the desired opportunity to manage the building production process in order to achieve efficient, cost saving, and quality projects in Anambra State.

Improvement of methods of obtaining urban TMY and application for building energy consumption simulation

In the development process of building energy conservation design, the correct provision of local Typical Meteorological Year (TMY) data is a prerequisite and basic work to evaluate building energy consumption, which directly affects the fine use of outdoor data for building energy conservation. Based on the recorded and observed data of meteorological stations in China, the acquisition and correction methods of TMY were studied by mathematical statistics and target searching, and the building energy consumption simulation of urban office buildings was conducted to verify the accuracy of the method, including:(1) Reviewed the generation method for TMY and the acquisition of data.(2) Based on the existing TMY data, the best spatial interpolation method of adjacent stations is studied by using the standard deviation method, and the selection method of the best number of stations on a large regional scale is given.(3) An improved method of urban environment TMY is proposed. The dry bulb temperature and relative humidity of the building site are corrected to generate TMY under Urban Heat Island (UHI) effect. The research in this paper improves the coverage and accuracy of urban TMY data and supplies basic research support for building energy-saving designs.

Comparative Study of Natural Lighting Quality in Sharia Housing Based on Daylight Factor Evaluation Using Autodesk Revit

The Islamic residential concept is the famous tagline that several real estate developers chose for their housing products today; it attracts customer attention, primarily from the Muslim community. But only some housing products are suitable to all the ideal criteria of the Islamic Residential concept. Excellent Sharia housing must fulfill all Islamic residential concept requirements, including public facilities, open space, and building quality. The strategy of the ideal Islamic housing concept requirement is optimal natural light and ventilation in the entire room. The inner courtyard is one of the solutions to afford this strategy. The types of openings also affect the daylight penetration in a room. Autodesk Revit Simulation evaluates this research about the daylight factor aspect of Islamic housing in Sharia housing. The research method is a qualitative, quantitative, and comparatively mixed method. The minimum requirement of daylight factor for housing is 5%. The study object shows that in the case of Medina Residence 1, it sufficiently offers the most daylight factor affordability in a Sharia housing project. The research hypothesis is to maximize the daylight factor by modifying several types of windows and adding skylight openings to increase the daylight factor of the entire room. Increased wall window ratio and more inner open spaces are the solutions for the minimum size of the building site. In the case of Medina residence 1, the skylight opening can be applied, but the effect is less significant than making more openings facing the open space.

Analisis Biaya Pembangunan Site Facilities Proyek Revetment dan Retaining Wall Dermaga Benoa

Process of a construction project is knowing how much a building will cost. Like the main building, the project site facilities also require costs that are not included in the direct financing of the project. The goal is to provide detailed information on the cost of building site facilities and to serve as reference material for the preparation of RAB site facilities. Implemented in the Revetment dan Retaining Wall Harbor Benoa project, the survey it was found that this project had built a number of temporary facilities but did not clearly detail the cost requirements. The research used descriptive quantitative methods and data collection in the form of surveys, observations and interviews. Survey to measure temporary buildings at the project site and find unit prices of tools, materials and labor at shops or foremen around the project area. Observation observes the layout of the building which will be outlined in the field layout drawing.An interview with the project manager was conducted to find out the total cost of the project and the costs incurred by the contractor for construction. Data analysis using Microsoft Excel by entering all components to be analyzed. Based on the results, it is concluded that the site facilities that are built are the contractor's office, health room, motorcycle and car parking, workers' toilets, directors' and consultants' offices, LAB rooms, cement and plywood warehouses, mechanical warehouses, security and K3 posts, workers' beds, trash bins, and water reservoirs. The comparison of site facilities cost to contract is 0.253%.

St Stephen's, Vienna, and the crises of 1408: practice theory and the socio-politics of the medieval building site

ABSTRACT In 1408 Vienna's politics were traversed by violence. Dynastic conflict among the Habsburgs and internecine differences between residents culminated in executions and overthrows of the city's government. Concurrently, building work at the city's largest church – overseen by leading figures in its civic politics, also victims of one of the year's purges – slackened. It was a moment when high politics, architectural production and the everyday practice of urban life intersected in ways unusually visible to the historian. Historians have adopted different historiographical positions for positing medieval architecture as a socio-political phenomenon, based on unilateral acts of princes and churchmen, dynamics of class conflict, administrative techniques of project managers or shared ‘imaginaries’. This article reflects on the events of 1408 using a new approach, taken from practice theory, to describe how the building site, reconceptualised as an open-ended bundle of doings and sayings, constituted and transformed the late medieval Viennese social.

Der große Baukasten

Abstract In Eberswalde (Brandenburg), a model house estate built in 1931 by Hirsch Kupfer- und Messingwerke has been preserved. The special feature of the eight house types built in lightweight construction is their outer skin of copper sheets. The structure consists of wall segments prefabricated in the factory, which were plugged together on the building site using patented connecting elements. One of the houses was built under the supervision of Walter Gropius, who for a short period of time was in charge of the factory’s house construction department. Here he tried to realize his idea of the building kit on a large scale, in which houses were to be produced on stock in factories. A considerable amount of plans as well as correspondence prove how profoundly Gropius was concerned with the development of the copper houses.

Early Byzantine city walls of Hierapolis in Phrygia: demolishing and recycling the Imperial era monuments

The study concerns the city walls of Hierapolis in Phrygia (Denizli, Turkey), which were built in the second half of the 4th century AD or at the beginning of the 5th century AD, by systematically recycling architectural blocks from Imperial-era public monuments and funerary edifices. The preserved remains of the fortifications enclose the city along its northern, eastern and southern sides, leaving out large sectors of the urban area. Within the research activities of the Italian Archaeological Mission, topographical DGPS surveys of the remains were performed, and a geodatabase of the reemployed blocks was implemented with three main aims: i) the reconstruction of the building site of the city walls; ii) the identification of the demolished monuments of the Imperial-era used as “quarries” and the study of the procurement strategies of stone materials in the early-Byzantine Hierapolis; iii) the analysis of the relationship between the large building site of the fortifications and the other coeval construction sites and their impact on the socio-economic life of the city. The research allowed us to trace the development of the building site of the city walls, which, starting from the north, mainly reemployed blocks from the necropolises, North Theatre, North Agora and the shops along the plateia not-included into the early Byzantine Hierapolis. Moreover, numerous materials from the Gymnasium and other monuments located in the central part of the city but not yet identified on the ground were especially reused in the eastern and southern sectors of the walls. Lastly, the location of the recycled blocks made it possible even to reconstruct the various transportation routes linking the demolished monuments to the different sectors of the city walls. On cover:Late Roman wall, the portion immediately south of the West Gate (Porta Oea) with re-used blocks from first-century mausolea (Drawing by Francesca Bigi) and Tombstone of Regina from South Shields (Arbeia) (Tyne and WearArchives and Museums/ Bridgeman Images).

Cleaner air for vulnerable people – Finding better locations for essential building premises

Long-term exposure to ambient air pollution even at relatively low concentrations is associated with adverse health effects especially for children, the elderly and people with pre-existing chronic disease. Due to a variety of urban planning decisions, essential building premises attended by these vulnerable groups may be sited in locations exposed to higher levels of air pollution. Using high spatial resolution air pollution concentrations estimated by satellite-based Land Use Regression (LUR) models in Australia, we mapped and approximated the annual average concentrations of particulate matter (PM2.5) and nitrogen dioxide (NO2) at schools, child care centres, aged care facilities and hospitals across Sydney. We found that 137 (3.1 %) and 287 (6.4 %) of the total number of essential buildings assessed were exposed to annual average PM2.5 and NO2 concentrations, respectively, where: the air pollutant concentrations were greater than the median concentration of other locations in the surrounding Local Government Area (LGA), and; air pollutant levels were greater than the 90th percentile concentrations for Sydney, and; air pollution at the essential building location was at least 1 µg/m3 for PM2.5 or 2 ppb for NO2 greater than the 25th percentile concentration of other locations in the LGA. Based on these criteria, we found that many essential building premises in Sydney were in high air pollution locations and there were other meaningfully lower air pollution locations within the surrounding area. Air quality is becoming an increasingly important issue for local jurisdictions to consider as more essential amenities are required to serve denser populations in busier places exposed to more air pollution. Our study showed that high resolution maps can be used as a health-based planning tool to encourage the siting of buildings at locations better protective of health.

Effect of Portland Cement on Mechanical and Durability Properties of Geopolymer Concrete at Ambient Temperature

Environmental concerns have prompted researchers to focus on the development of alternative building materials like geopolymer concrete. However, their implementation requires curing beyond 60°C, which limits their application on building sites. This study aims to design a geopolymer concrete at room temperature (30 ± 5°C) in a laboratory in Burkina Faso using a metakaolin-based geopolymer binder activated by an alkaline solution of NaOH and natural aggregates. Portland cement type CEM I 42.5 was used by mass substitution (0 to 25%) of metakaolin to promote curing at ambient temperature. The samples were cured for 7 to 28 days and characterized for physical, mechanical, and durability properties. The results showed that the incorporation of 0 to 20% cement significantly improved the compressive strength from 9.9 to 30.5 MPa and the tensile strength from 1.2 to 2.2 MPa. However, Portland cement has various effects on the durability of geopolymer concrete. It reduces the porosity accessible by water from 15 to 13% and decreases the resistance to acid attack by increasing the mass loss from 2 to 7%. This confirms that common concrete types C20/25 or C25/30 can be casted using geopolymer concrete on the sites in Burkina Faso once their durability is confirmed.

백제 웅진기 건물지의 평면변화와 위계

This The palace is a formal structure representing the authority of the king and can be said to be the largest complex building group since ancient times. Ancient countries in Northeast Asia generally used ancient Chinese palaces as models and built palaces, and various norms and rituals were applied.
 However, since differences in perception of nature, topographical conditions, and differences in the use of tools and living customs cannot be excluded, a review based on the topography and environment of the area is needed in the construction of the royal palace. Therefore, the structure and hierarchy of royal palace-related buildings in Gongsanseong Castle, which is the Castle of Woongjin in Baekje, need to be judged on the premise of understanding the use and location of space using natural terrain. In particular, in the case of ground buildings, it is difficult to grasp the superstructure based on archaeological investigations, so there is a limit to the hierarchical review of ancient architecture defined by the system. Accordingly, based on the size and structure of the building site in the Woongjin period Baekje Castle, and the spatial compartment that can be identified in the arrangement of the building within the unit space, we tried to understand the changes and hierarchies of the building site in the Woongjin period of Baekje.
 First of all, the biggest changes in the building site in Baekje's Castle during the Woongjin period include a ground building, standardization of plane structure and scale, and spatial composition by compartments. Although the size of the building site has been miniaturized compared to the Hanseong period, it can be seen that the grounding of the building has been stably carried out based on the wooden structure. The structure of the building site shows that the Byeokju-building(벽주건물) and the Gulipju-building(굴립주건물) in the early Woongjin period are expanded from the initial planar structure to the side, resulting in space division and enlargement by the compartment.
 The hierarchy of Baekje building sites during the Woongjin period can be divided around location, plan and size, and left direction. As for the location, planned building arrangements were made after the site was divided by infrastructure such as roads and drainage channels to overcome the limitations of the topography such as hilly lines and lowlands. It can be inferred that the space was controlled in the left-facing arrangement that conformed to the location and land of the building, and the spatial composition and hierarchy according to the function were distinguished. The floor plan of the building is divided into a square Byeokju-building(벽주건물) and a Gulipju-building(굴립주건물).
 The distribution of buildings differs between the central building group and the surrounding building group. In the ruins related to the royal palace in the south of Gongbukru(공북루), the space is divided into five stages of land, and the land gradually increases. In addition, the presumed royal palace site forms a land as it gradually rises from the access road to the east. In other words, you enter while looking up at a building located on a high land from a low area. It's worth noting that it's forced to look up from a low point of view, which highlights the authority of the building and emphasizes symbolism.

Active BIM system for optimized multi-project ready-mix-concrete delivery

PurposeReady-mix concrete delivery problem (RMCDP), a specific version of the vehicle routing problem (VRP), is a relevant supply-chain engineering task for construction management with various formulations and solving methods. This problem can range from a simple scenario involving one source, one material and one destination to a more challenging and complex case involving multiple sources, multiple materials and multiple destinations. This paper presents an Internet of Things (IoT)-supported active building information modeling (BIM) system for optimized multi-project ready-mix concrete (RMC) delivery.Design/methodology/approachThe presented system is BIM-based, IoT supported, dynamic and automatic input/output exchange to provide an optimal delivery program for multi-project ready-mix-concrete problem. The input parameters are extracted as real-time map-supported IoT data and transferred to the system via an application programming interface (API) into a mixed-integer linear programming (MILP) optimization model developed to perform the optimization. The obtained optimization results are further integrated into BIM by conventional project management tools. To demonstrate the features of the suggested system, an RMCDP example was applied to solve that included four building sites, seven eligible concrete plants and three necessary RMC mixtures.FindingsThe system provides the optimum delivery schedule for multiple RMCs to multiple construction sites, as well as the optimum RMC quantities to be delivered, the quantities from each concrete plant that must be supplied, the best delivery routes, the optimum execution times for each construction site, and the total minimal costs, while also assuring the dynamic transfer of the optimized results back into the portfolio of multiple BIM projects. The system can generate as many solutions as needed by updating the real-time input parameters in terms of change of the routes, unit prices and availability of concrete plants.Originality/valueThe suggested system allows dynamic adjustments during the optimization process, andis adaptable to changes in input data also considering the real-time input data. The system is based on spreadsheets, which are widely used and common tool that most stakeholders already utilize daily, while also providing the possibility to apply a more specialized tool. Based on this, the RMCDP can be solved using both conventional and advanced optimization software, enabling the system to handle even large-scale tasks as necessary.

Utilization Of Drones as A Tool For Monitoring Progress In Civil Engineering Construction Using Enugu State As A Case Study

The hazardous nature of the Nigerian building construction sector is alarming due to the dearth of construction data and records of incidents that have led to the loss of life, property damage, injuries, and loss of materials on construction sites This study aims to assess the effectiveness of drone monitoring of security and safety at Nigerian building sites in reducing hazardous site conditions. The following hypotheses were made to meet the study's goal and objective to assess the level of drones using Enugu State in Nigeria as a case study. The Methodology includes a literature survey and questionnaires at various sites. 242 people responded to the survey. To assess the constraints of employing quadcopters and other drones/UAVs (unmanned aerial vehicles) for safety and security surveillance on construction sites in Enugu State, Nigeria. Inventive drones and the DJI Phantom 3 Standard Both types of drones were used in this experiment. The targeted experts and stakeholders included architects, builders, engineers, quantity surveyors, land surveyors, estate surveyors, and clients. The data were analyzed using the SPSS computer program for Windows, version 23.0. Only 65 per cent of respondents were aware of the drone idea, although 51 per cent of respondents used drones in various construction monitoring sectors. The adoption rate of 17.6% for safety and security monitoring, however, was deemed low by participants in the Enugu State building construction sector. Drones have been successfully used in developed countries such as America, Europe, China, Australia, and India, to monitor safety and security as well as the progress of both large-scale and high-rise construction projects. As a tool for monitoring the security and safety of all building phases, drones are still in their infancy from the Nigerian perspective. The successful use of drones in Nigeria is encouraged since realistic imagery generated from drones may be used for analysis and evaluation of ongoing construction work, including planning movement on site and monitoring materials on site and may be archived for future purposes

Quantification of Moisture in Masonry via AI-Evaluated Broadband Radar Reflectometry

Humidity, salt content, and migration in building materials lead to weathering and are a common challenge. To understand damage phenomena and select the right conservation treatments, knowledge on both the amount and distribution of moisture and salt load in the masonry is crucial. It was shown that commercial portable devices addressing moisture are often limited by the mutual interference of these values. This can be improved by exploiting broadband radar reflectometry for the quantification of humidity in historic masonry. Due to the above-mentioned limitations, today’s gold standard for evaluating the moisture content in historic buildings is still conducted by taking drilling samples with a subsequent evaluation in a specially designed laboratory, the so-called Darr method. In this paper, a new broadband frequency approach in the range between 0.4 and 6 GHz with improved artificial-intelligence data analysis makes sure to optimize the reflected signal, simplify the evaluation of the generated data, and minimise the effects of variables such as salt contamination that influence the permittivity. In this way, the amount of water could be determined independently from the salt content in the material and an estimate of the salt load. With new machine learning algorithms, the analysis of the permittivity is improved and can be made accessible for everyday use on building sites with minimal intervention by the user. These algorithms were trained with generated data from different drying studies on single building bricks from the masonries. The findings from the laboratory studies were then validated and evaluated on real historic buildings at real construction sites. Thus, the paper shows a spatially resolved and salt-independent measurement system for determining building moisture.

Building foundation settlement in groundwater lowering on sliding territory of Lagerny Garden in Tomsk

Groundwater lowering is a method of stabilizing landslide slopes. To date, the effect of water reduction on the technical condition of buildings has not been sufficiently studied. This may negatively affect the technical condition of buildings due to the development of additional deformation of foundations and foundation soils.Purpose: The aim of this work is to assess the impact of cased hole with filters on the technical condition of buildings in the area of groundwater lowering.Methodology/approach: Long-term field observations of the groundwater level at the water supply site; monitoring of the technical condition of buildings; analysis and generalization of the data obtained.Research findings: Based on annual monitoring of the building height, monitoring of changes in the building state and the engineering and geological analysis are performed in the period from 1987 to 2020. It is found that groundwater lowering leads to building deformation and a decrease in its technical condition due to nonuniform soil compaction in this area.Research implication: Groundwater lowering near buildings can significantly affect their technical condition due to the soil compaction even at a considerable distance from the waterlowering devices. In developing groundwater lowering projects, special attention should be paid to heterogeneity of the ground layer on the building site and its impact on the formation of relative deformation of buildings.
