Construction Practice

Alternative solutions to joints of outer wooden solid log walls are based on the current situation on the construction market, which reflects general change in attitude towards the environment. Apart from the evaluation of materials and products in accordance with technological and economic aspects, attention is paid to the effect of individual elements on the environment. This trend is reflected in construction practice by a comeback to original materials and expanding designs of residential buildings on the basis of easily renewable material resources, e.g. wood, which is relatively easily available and renewable construction material. When designing and constructing wooden buildings, it is necessary to take into account specific properties of wood (particularly volume changes), which need to be considered for solutions of individual details. Bed joints of wooden solid log walls are still a problematic detail in terms of thermal technology. It is a contact of two horizontal construction elements – beams, where maximum weakening of the wall thickness occurs. This spot is a relatively frequent place of a recurring thermal bridge during the wall construction. Analysis and improvement of this critical place of wooden houses, which has been more and more frequently built in the Czech Republic, would lead to their better evaluation in terms of heat-technical properties. The aim of the project was to design and examine adjusted variants of shape solutions of joints in between individual solid wooden elements. The project particularly focused on monitoring of surface temperatures in the areas of critical details – bed joints.

Adobe, in the form of sun-dried bricks and clay or lime/clay mortar, has traditionally been the primary construction material in Iran. Presently, this type of construction still constitutes a notable portion of the buildings in the urban areas and a majority of the buildings in the rural areas. Performance of traditional adobe construction during numerous Iranian earthquakes has generally been poor. Low material strength, poor workmanship, lack of proper connections between building elements, and the excessive weight of the building because of thick walls and massive roofs, are but a few of the shortcomings that contributed to the general weakness of these buildings under earthquake loads. This paper examines the performance of adobe residential buildings during the Bam, Iran earthquake. The current rehabilitation trends for this type of construction in Iran are also discussed.

This paper focuses on the Italian market where surveys, interviews, and a workshop were conducted, and then a diagnosis was made on the results obtained. Results show that technological innovation on BIM tools cannot be a stand-alone action to reach a full digitalization of the renovation sector, but it shall be supported by a major awareness of the actors involved, improved skills, and competences, as well as an important change of approach in the current construction practice.

Construction Practice

Although the most prominent material in contemporary construction practice due to its obvious advantages, concrete possesses a number of drawbacks. One of the advantageous principles for decades is to enable a large scale on-site application of this material with acceptable properties, needed to withstand specific conditions. A concept of 3d printing concrete presents a promising ground for further improvement of this principle. While maintaining as much as possible of the prerequisite and common properties to answer the construction demands, this material has to evolve as much as possible to fulfill the 3d concept, which would, in turn, pave a way for the next level of its construction applications. This paper presents the main principles of 3d printing concrete, by discussing the main goals and the drawbacks that have to be solved prior to wider application. Also, one specific facility- wind tower will be reconsidered as a potentially promising ground for this old construction material dressed in a new suit.

Construction Activity

AbstractConstruction companies are important economic actors in every country. Their activity translates into employment levels, tax revenues, and the provision of new spaces that require further expenditure on equipment, thus stimulating consumer spending. The activity of construction companies depends on the demand for space, the state of the economy and the financial market. Undoubtedly economic disturbances in the form of a recession have a significant impact on construction activity. The authors were interested in whether the boom and recession in the selected countries were similarly reflected in the activity of construction companies. In particular, they were interested in residential construction activity, although it was not possible to select companies that would only deal with residential construction. The authors selected four post-socialist countries and two countries which are called winners of the integration process due to their enormous economic growth. The authors outline the residential construction and construction sector results and activity in the Czech Republic, Poland, Slovakia, Hungary, Spain and Ireland, and draw a wider picture for analyses of construction companies’ financial results for the years 2003-2012. This period was chosen because it covered periods of both boom and bust. All enterprises were part of the sector denoted in the Amadeus database as primary code: Eurostat NACE Rev. 2 with codes: 41 - Construction of buildings: 4110 - Development of building projects, 4120 - Construction of residential and non-residential buildings. Due to the specificity of the construction sector the authors divided the surveyed enterprises into two groups – all companies; and only large and very large companies. It was not possible to separate data specifically with respect to residential construction companies.

The Impact

This paper analyzes the impact of Trombe wall construction on heating and cooling demands of building with form (rectangular single-store building of about one hundred square meters area) which is common for individual residential buildings in the Republic of Serbia. Trombe wall, as a representative of a passive solar design, was installed on the south wall of the building. Model of the building was made in the Google SketchUp software, while the results of energy performance were obtained using EnergyPlus and jEplus. Parameters of thermal comfort and climatic data for the area of city of Belgrade, Republic of Serbia, were taken into account. Coverage of the south fa?ade was varied, as well as the thickness of the thermal mass and orientation. Energy consumption of the object is discussed, based on obtained results of the analysis. According to comparative analysis of the above mentioned models it can be concluded that the application of the Trombe wall structure on south side may lead to savings of 33% on heating, but also the higher energy consumption for cooling. Total energy consumption on an annual basis is reduced by using this system.

Spatial Data Model

This article is focused on the creation of a data model of an information system to support the processes of population sheltering (PoS). PoS processes have undergone significant changes in the Czech Republic. The PoS system was transformed for the use of improvised shelters. For sustainable PoS, it is necessary to standardize the approach of crisis management staff. Key research hypotheses: the data model must respect the methodological framework of planning and implementation of the PoS, especially when used for the design and implementation of the improvised shelters; the standardization of residential buildings can be used to facilitate and streamline the sustainable process of planning of the PoS; the unified data model of the PoS can be considered suitable for standardization and development in the field of sustainable planning and implementation of the PoS. Softwares such as SW QGIS desktop 2.6.0, OpenStreetMap (OSM) spatial database, ESRI shapefile format, and S-JTSK/Krovak East North 5514 coordinate system were used for the verification of the spatial data model, and ASP.NET MVC 4.7.2 Microsoft SQL Server Express 2019, jQuery 3.3.1, Bootstrap 3.4.1, Kendo UI 2019.1.220, and virtual Windows Server 2016 were used for the implementation of the physical data model. The physical data model substantiates the benefits.
