This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit.   The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes.   The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process. The importance of testing the profitability of the idea is also being discussed. The interviews also indicated that the pre-project phase is not linear but rather transactional and that the original alternatives presented to the client lead to new client desires and requirements.

The topic of this thesis is detailed design of supporting structure of continous box girder bridge across a deep valley called Lazný creek. The bridge have to pass the second class road with category S 9,5. The design is processed by two options. The chosen option is designed as a girder with five spans 44,8 m + 55 m + 55 m + 55 m +44,8 m. Total length of bridge is 268,57 m, the main girder is gradually cast into the formwork suspended on a special ceiling scaffolding. The axis of the bridge is in a plan straight with the constant transversal slope 2,5 %. The thesis contains six models in software SCIA ENGINEER. Part of the work is situated on time depended analysis with construction phases. Assesment of ultimate limit states and serviceability limit states were done by hand according to the valid standards and regulations. Structural analysis, drawing documentation and vizualization are parts of this work.

This diploma thesis deals with the design of a new bridge construction over a multi-lane communication. The converted road is a pedestrian and biking trail connecting significant agglomerations. Three studies were worked out in this thesis and the C variant was selected for further detailed processing. It is an unsymmetrical suspended bridge with a cast-in-place deck. In the section above the communication, the bridge is made up of prefabricated segments. Suspension of the structure is made of two sloping pylons forming a V-shape. The analysis of the construction was carried out in the MIDAS Civil program, where a complete model of construction was entered, including a subsequent estacade. The model describes the construction process and includes creep and shrinkage of the concrete. The traffic, temperature and wind loads were used. The design was assessed for the ultimate limit states and serviceability limit states. The assessment was carried out in the IDEA StatiCa program, supplemented by manual calculations. The static calculations also include assessment of the harmonic response. Subsequently, overview drawings, detailed drawings and visualizations were developed.

This thesis occupies with the design of the road bridge over the stream Živný, a railway lane and a projected road between Běleč village and Husinec village. There are designed three variants of bridges. The variant no. 1 – continuous box girded beam – was chosen for the detailed analysis. The pre-stressed concrete road bridge is designed and evaluated according to European standards – Euro codes. The sequential construction influence and its impact on the construction is also considered in the calculations. The drawing documentation and the visualization of the bridge are made.

My diploma thesis deals with design of the bridge number 202 on expressway in Slovakia. The bridge leads across the road number I50 (between Trenčín and Bánovce nad Bebravou) and railway number 130 (between Trenčín and Chynorany). For each course there is a separate super-structure. Only left super-structure is considered for the work. The box girder with four spans is chosen from three variations. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural model of construction is made as a spatial bar model. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

The subject of this bachelo r’s thesis is the design a new supporting bridge construction in Prešovský kraj, district Levoča the territory of Slovak Republic. This object is located on the highway D 26,5/120, at kilometer 13,499 795 and communication of third class – 131-00 bridges. The objective is the design of a perpendicular four-span construction, which is proposed in three variants. The first variant is a chamber girder with inclined walls from post-tensioned concrete height 2,480 m. The second variant is composed of two beamed cross-section and the third variant is composed of one beamed cross-section. For detailed assessment the first variant was chosen with a length of bridging of 166,000 m. The calculation of load effects is done by software Scia Engineer and compared with a manual calculation according to current standards. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

The subject of this thesis is the design and assessment of the bridge across the expressway and the deep valley in section Hričovské Podhradie - Lietavská Lúčka of highway D1 in Slovakia. The box girder structure with eleven spans was chosen of three variants. For each course there is a separate structure. The design of the bridge is carried out according to limit states including consideration of the impact of construction. The assessment of the construction is carried out using the beam model. The appendix contains structural analysis, drawings and visualization of the bridge.

The diploma thesis deals with the design of a road bridge on the I/57 expressway over the relocation of the cycle path, the Opavice river and the local road, which involves the relocation of the access to the waterworks. The bridge structure is located in the territory of the town of Krnov. A study of the area's bridges is part of the project and three studies have been prepared. Study A was chosen for detailed processing. It is a continuous box girder bridge with three spans. The superstructure is designed as a monolithic, post-tensioned structure. A sliding girder is being investigated for the structure's construction. Scia Engineer 18.1 is used to do the load effects computation. Only the consequences of vertical load effects have been addressed, with no consideration of horizontal load effects. The structure was evaluated using limit states, taking into account the impact of construction on its design.

The subject of this thesis is the design and analysis of five-span bridge construction across the railway on the route Zábřeh - Šumperk and the Morava river. There will be made separated bridge for each direction, only right bridge is considered in the thesis. Object is located to 1st class road I/44 on the route between Mohelnice and Jeseník. Three variants were designed - two prestressed chamber girders, one prestressed chamber girder with prefabricated consoles and construction of concrete slab mixed with two steel girders. After these variants were weigh up and the first one, with the length of cantilevered construction 235,6 m and maximum lenght of span 60 m, was chosen for analysis. Calculation of load effects was made by software Scia Engineering 2013 and the analysis was made according to current standards by manual calculation depending on limit states and their influence on the design as well. Drawing documentation and visualization are also part of the thesis.
