Organisation and activities analysis of the surveying and mapping authority of the Republic of Slovenia as part of public service
Get PDFIn the introductory part of the master's thesis we introduce an overview of the international trends on the area of spatial data infrastructure with the land administration system which represents one of the fundamental spatial infrastructures of the public surveying service. What follows is a description of the development of the surveying and mapping services in Slovenia which has since its beginnings after the Second World War up until now experienced numerous changes mostly because of economic changes and different political orders. The main part of the thesis first deals with the theoretical and then practical aspects of the organisation and activities of one of the fundamental parts of the public surveying services, that is, the Surveying and Mapping Authority of the Republic of Slovenia, which already faces many challenges and opportunities in the area of the spatial infrastructure in the future. We thoroughly study the structure of those employed by the Surveying and Mapping Authority of the Republic of the Republic of Slovenia and its activities in connection with financial operations in the last few years. In addition, we use a survey to analyse the employee satisfaction and their views on the development of the institution that employs them
Overview of documentation and permits during residential building construction
Get PDFThe thesis describes the documentation required for the residential building, that needs to be present on the construction site on general contractor‘s side. The chapters follow in the same sequence as the site works. As a consequence, we present first the documentation that needs to be prepared prior to the construction. The main part of the thesis presents detailed description of all required documents that are necessary for uninterrupted and quality construction. The final part presents the documentation required for the successful technical review, so that operation permit can be obtained; handing over the structure to the owner, preparation of the final bill and performance bond; and finally, listing the building into the official databases. In the last chapter is presented an example of single-family house
Usability of Revit families for the modelling of concrete structures
Get PDFWithin this thesis, we discussed the making of families which are the basic building blocks of the information model used within the software Revit. Families are groups of parametric elements that contain information about their properties and their graphical representation.\ud
Among the providers of BIM software applications, we have chosen Revit. Revit is a BIM software package from American corporation Autodesk, intended for the development of building information models (BIM). The BIM process strives towards the unification of information to be within a single building information model which provides all of the information about the planned building and it is the main source for the extraction and entry of all information by all participants within the project. BIM is significantly different from the computer-aided design (CAD) approach to planning buildings, which is why we have compared them to each other and provided basic guidelines required for a successful transition from CAD to BIM.\ud
The thesis focuses on the description of different types of families and determines their usefulness for building a structural model in Revit. After that, a recommended family modelling process is presented, consisting of four steps, namely: establishing the reference planes; appending dimensions to reference planes; the allocation of parameters to selected dimensions and the input of 3D massing, which represents the graphical representation of the family. The emphasis of this thesis is focused on the modelling of families, representing concrete building elements. With the use of practical examples we have shown different ways of making families, which differ depending on the purpose of the family. We then used pre-existing families to demonstrate how one can insert a family into an existing system family or into the structural model.\ud
We find that the use of families within the Revit software is user-friendly as it enables us to quickly design a structural model, given basic knowledge of the program. Compared to traditional CAD software, Revit appears more difficult to use at first glance, because a large part of Revit is based on the parametric approach to design and slightly less to the visual one. However, the use of Revit tools is very well guided, since we are automatically informed of subsequent steps required to be taken, besides the software itself warns us if any errors occur due to the user input. Although the insertion and use of families is simple, the choice of appropriate types of families and their creation is relatively complex. It is necessary to know exactly what the purpose of a family is and in what way we intend to use it. On this basis, we devised the optimal approach to create a family as well as selecting an appropriate type. The modelling of all variations of families has the same approach in principle; however, the process of creation can vary. A well modelled family that has the ability to adapt to any given situation may require more time to develop than a 2D drawing using CAD software. Therefore, we need a lot of experience in the creation of families, based on which we can choose the optimal approach that will meet the structural requirements and won’t be counterproductive to time invested.\ud
We end with a practical example showing the usefulness of importing a Revit Architectural model in a new Revit project for the purpose of developing an architectural template and creation of a structural model. We find that the use of architectural templates greatly simplifies the work, because it serves as a reference when we insert a family in a structural model. One of the major advantages offered by linking a Revit architectural model with a new Revit project is the possibility of automatic control over architectural levels, which enables us to react quickly to any changes in the architectural model by adjusting the structural model
The production of Digital Relief Model of a quarry by using Terrestrial Laser Scanning Technology
Get PDFThis thesis presents the theoretical production of digital relief model. The practical part was carried out in the Suhor pri Vinici quarry. The field data collection consists of network performed baseline measurement and scanning of the southern part of the quarry. The measurement was taken with Leica Nova MS50 multistation, which allows classical terrestrial measurements as well as terrestrial laser scanning. The results of the adjusted baseline network are used for the placement of the point cloud in the national coordinate system D48/GK. The processed point cloud was used for creating a digital terrain model to calculate the quarry volume

Analysis and evaluation of urban brownfields - case study
Get PDFIn graduation thesis we discussed brownfield site concept, overview good practises and described previous activities on this field in Slovenia. We presented used work methodology in detail, which almost matches with ongoing projekt »Comprehensive brownfields inventory and analysis methodology, implementation of pilot inventory and establishment of the up-todate register« (Lampič et al., 2016) methodology. We implemetated and analysed seven sites in Tržič municipality, which is convenient to brownfield site determination criterion. We compared inventoried sites with sites inventoried in 2015 in project »Establishing of a active spatial and functional degraded sites for the Gorenjska region« (Lampič et al., 2015). We showed diference in detail capture and type definition of brownfield between those two projects. We made a restoration and revitalisation suggestions for considered sites

Economical thermal insulation thickness and price comparison between classicly built and prefabricated single family house
Get PDFIn the thesis, I discussed the economic thermal insulation thickness on the outer wall and under the base plate. I also compared the prices of constructing a classically built and prefabricated house. In the first part, I presented characteristics of the classically built and the prefabricated house and defined the theoretical bases of energy efficiency. In the second part, I described the chosen object and prepared an inventory of the material for the cases of a classically built house and a prefabricated one, where I compared the prefabricated house by Marles with the N14 composition of the outer wall. Based on the chosen object I calculated the economic thermal insulation thickness of the outer walls for a period of 60 years, where the façade is being renovated twice, and the economic thermal insulation thickness under the base plate with the assumed lifetime of 100 years for the case of a classically built house. I also considered the possibility of no thermal insulation under the base plate.\ud
For the calculation, I used the dynamic method, used in economics, called net present value. In continuation I prepared an inventory of the work and material for the construction of the chosen object and so compared the prices for the construction of a classically build and a prefabricated house. For the purpose of comparability, I unified some elements of the classically built house with the offer for the prefabricated house Marles Mega N14, so that both objects are the same in terms of energy efficiency and equipment. In the thesis, I showed that the installation of large amounts of thermal insulation pays off at the outer walls as well as under the base plate. The results of the price comparison for the classically built house and the prefabricated one showed that the construction of a classically built object is still cheaper for about 20%
Effect of shape of the specimen and direction of casting on compressive strength of fibrous concrete
Get PDFIn this thesis, we investigated the properties of concrete reinforced with steel fibers. We have considered the influence of the orientation of fibers on the mechanical properties. We describe their own process of making molds in workshop and manufacturing process of the specimens in the concrete plant. Experimentally we measured the strength of the test specimens of various shapes, with a variety of steel fibers. We also made bending tests. We have found that the shape of the test specimen and the direction of casting of concrete into the mold affects the size of the compressive strength of the fibrous concrete
