Spatial analysis of the residential real estate market in slovenia in 2007-2013
Full text linkIn the diploma thesis there are presented and analysed activities in the Slovenia residential real estate market in 2007–2013. Analysis was performed on a basis of data of the Geodetic administration of the Republic of Slovenia. We analysed a number of transactions as well as an average price of a square meter of a flat or a house in Slovenian municipalities. A special attention was paid to analysis of a dynamics of residential real estate market in important urban centres in the Republic of Slovenia, i.e. in regional centres defined in the Spatial Development Strategy of Slovenia. Findings of our study are in accordance with available literature
Comparison of methods for calculation of loads in constructions in coastal engeneering
Full text linkIn the thesis we examined and compared the four most common methods used to calculate pressures due to dynamic loads of waves on constructions in the coastal engineering: the methods Sainflou, Goda, Minikin and Takahashi. In the thesis we first describe the theoretical background of all four methods. In the second part we elaborate a simple model using MS Excel software tool, which can be used by each of the recognized methods to calculate the pressures on a coastal construction at different wave parameters and characteristics of the coast. The obtained results are logical and expected with regard to the theoretical background of all methods under consideration. The developed model represents a useful tool for determining pressures due to waves in coastal engineering that can serve the designers, as well as in the teaching/learning process at UL FGG
Water supply optimization of summer house on island Silba
Full text linkWater is a very important, if not the most important natural resource. We cannot imagine life without it, still we are at the point where we have to find new solutions for saving, exploitation and reuse of water. Closing the tap while brushing our teeth simply just isn't good enough any more. Water conservation is a big challenge and is especially important in areas where water supply and sewage\ud
systems are not installed so the water has to be provided in an alternative way. Therefore problems with water supply often occur in remote areas, islands, mountain huts. On the Croatian island Silba saving water is something very common. Most houses have a system for collecting rainwater, but that is often not enough, since the water usage well exceeds the size of simple water tanks. We set out to find the optimal solution for improving water conservation and reuse in a summer house. It is our opinion that the most comprehensive solution which would also make a positive impact on nature would be to build a constructed wetland. In vicinity of the house there is enough space for the\ud
installation, furthermore maintenance costs are low and treated wastewater could be reused for flushing the toilet and watering the garden
Reconstruction of toll plazas after the introduction of the free-flow electronic toll collection system
Full text linkFollowing the introduction of the free-flow electronic toll collection system will needed to rearrange toll plazas to allow free-flow in traffic. The areas of the newly built highway may arranged in several ways. It can be area for traffic control.\ud
The thesis was to show on the case of toll plaza Kompolje arrangement of highway through toll plaza and service areas for needs of traffic control and described some of the possible usages of service areas
The impact of cement type on the bond between concrete and reinforcing steel
Full text linkThe thesis researches the impact of cement types on the bond between concrete and reinforcing steel. The experimental part of the thesis includes laboratory research. Within the lab research we prepared concrete mixtures for which we used three different types of cement. From each type of concrete we created three test pieces. All the other components of concrete were the same and added in the same proportion. We have produced specimens in the form of cubes with a side of 20 cm. The cube was inserted with a ribbed reinforcing bar with a diameter of 20 mm which was piercing the center of the cube. The pull- out test was conducted in accordance with standard SIST EN 10080:2005. We burdened the reinforcing bar with tensile until the contact between concrete and the reinforcing steel was broken. Used types of cement differed in the amount of cement clinker and additives in the cement. Based on the research results we found that concretes using cement with a higher proportion of cement clinker achieve higher bond stresses between concrete and reinforcing steel. Increasing bond stresses are almost proportional to the increase of the cement clinker in cement
Comparative analysis of land cadastre borders and typical relief forms
Full text linkIn our graduation thesis we compare the marcation of owner's (land registry) borders with typical relief lines in the land registry municipality Črešnjice. All the analyses are carried out on the basis of graphic system data of the land register, laser scanning data of Slovenia and terrain measurements. Our assumption is that in some typical cases the border lines of the land are running parallel or even coincide with typical relief shapes such as shore terraces, forest paths and similar features. It is even possible to determine the border demarcation of the land registry municipality by recognizing the typical relief lines. Furthermore, this thesis presents the theoretical base of position accuracy, land registry display data, attempted land registry display data improvements, data used, the area of processing, software used and the description of terrain measurements. The results are compared with owners' land borders and typical relief shapes obtained from aerial laser scanning data and terrain measurements
Financial statements analysis as indicator system for construction company
Full text linkFinancial statements are an important source of information enabling disclosure of the financial and also general performance of a company. The thesis are addressing the\ud
performance of the 13 selected, large civil engineering companies in Slovenia using their publically available financial statements for the period 2005–2014 available from AJPES. Of 13 companies 8 companies went bankrupt in the addressed period of time. In the first part of the thesis I describe after general overview of the contents of financial statements necessary for overall understanding of the balance sheet and income statement. In the second part of my thesis paper the index method and the method with calculation of Zfactor is applied for the selected companies. In the second part I have performed a comparison of the selected indicators on the selected and Z-factor analysis. Standard set of evaluation approaches was later expanded with 5 new indicators which could be considered as important indicators demonstrating some specific characteristics in construction sector. Based upon the comparison of the two aggregated groups (A) still active construction companies and (B) construction companies which went bankrupt in the period 2005–2014 I can confirm that the financial statements alone enable early identification of critical situations in a company which can later result in its bankruptcy
Development of quality assurance system for building of traffic infrastructure projects on the example of asphalt
Full text linkTransport infrastructure covers road, rail infrastructure, infrastructure of airports and ports. The construction, maintenance and management of transport infrastructure is one of the most important tasks of each country to facilitate the mobility of people and goods.\ud
Transport infrastructure in Slovenia is mainly due to the construction of highways between 1995 and 2010, well developed. As a country at the crossroads of transport routes our transport systems will be heavily loaded also in the future. That needs to be used also in economic terms, the development of transport and logistics activities. \ud
In the thesis the system of quality assurance and quality control is displayed, which was developed during the time of construction of slovenian motorways in the period 1995 to 2010. The technical regulations of the system of quality assurance and quality control, institutions and professional bodies to produce technical specifications, and the organisational structure of the quality assurance system and quality control are described. On the basis of the parameters described above a critical analysis of the system is made, taking the asphalt as a construction product as an example of good practice.\ud
In Slovenia the necessary institutions for the establishment of a successful system have been established, but all of them do not carry out all of the assignments for which they were established. The biggest problem is reflected in the production of technical guidelines, including the scopes of works, which would have been necessary to produce according to the Law on the construction of the facilities as well as under the sectoral laws, e.g. the Law on the Roads. It also requires the administrator of the entire system, which may be the Ministry for Infrastructure or the Engineer DRI Investment Management,LtD., who has provided this role already in the past.\ud
In the recent years, the structures in the area of transport infrastructure in the country have been reorganized. The Ministry of infrastructure has been established, in the composition of which is also the Directorate for infrastructure. In addition to DARS a second large client DRSI- is established, which is responsible for state roads and railways. DRI Investment Management, LtD. became in agreement with the state an Engineer for most state projects. All this calls for the re-establishment of the system of quality assurance and quality control, that will assure connectivity and communication, through the expert commissions and the coordination of all actors in the investment process providing the production of technical documents such as policies, technical guidance, instructions, reminders, and inventories of acivities that are of key importance for high-quality and transparent realization of projects.\ud
DRC, Road and Transportation Research Association of Slovenia, LtD., that has been established for that purpose, modeled on institutions in the neighbouring countries, does not perform these activities. It is necessary to open a debate on this topic and to establish the operation. The thesis is a support to this debate and the achievement of the final goal: establishment of a system of quality assurance and quality control and production of technical regulation for the whole area of transport infrastructure
Methods for analyzing the discharge recession dynamics
Full text linkGraduation thesis presents theoretical basis for classical hydrograph recession curve analysis which are used to describe the dynamics of discharge recession. \ud
The first part of the thesis presents theoretical background on assessing different components of hydrographs. A new method which foresees the extraction of catchment sensitivity function is presented.\ud
In the second part of the thesis, New method is applied on rainfall and discharge data from two experimental catchments, the Mačkov graben and Kuzlovec torrents.\ud
Our task was to determine the periods of discharge recession for both stream, to get sensitivity function and compare them. The new approach demonstrated how streamflow time series can be used to construct a storage–discharge relationship which could be used for catchment characterization and to simulate the entire spectrum of hydrological conditions. In particular, the method leads to possible further quantitative estimates of catchment\ud
dynamic storage, recession in different time scales, and sensitivity to rainfall inputs
Assessment of hydroenergetic potential of the Žegar HPP on the Zrmanja river
Full text linkIn this thesis, based on measurements of the water flow at the water measurement station Nadvode, 7245 on the Zrmanja river in Croatia, conducted over the course of several years, the energy hydropotential of the potential Žegar hydropower plant was calculated. The Zrmanja river is not yet utilised for harvesting energy and as such offers possibilities for harvesting energy. Current energy trends emphasise to so-called renewable sources of energy. People have become aware of the fact that the utilisation of fossil fuels is limited and that at the same time their consumption causes great harm to the environment. On the other hand, hydropower plants, as a source of energy, emit almost no emissions in the course of their operation and do not consume other energy products. Therefore, they are classified as renewable sources of energy. For this purpose, the Croatian Rules on the Support for Energy Produced by Renewable Sources of Energy have been analysed. Based on geodetic data, a model was made of the terrain in the surrounding area of the Žegar hydropower plant as well as certain main technical characteristics of the power plant, which may in any way affect the calculation of the hydro-energetic potential of the Žegar hydropower plant. Data about the medium daily flows during the period of measurements was processed, evaluated and later considered in the calculation of the hydro-energetic potential. The hydro-energetic potential of the location was calculated for two types of hydropower plants, namely for the derivational hydropower plant and the accumulative hydropower plant. Both potentials have been compared with each other. Later, both types of hydropower plants were cost-assessed as well. Finally, based on the previously calculated hydro-energetic potential, an economic analysis of the feasibility of possible investments in both types of hydropower plant was conducted, this was achieved based on annual revenues, expenditures and the ability to pay back a possible loan for the construction of the hydropower plant
