Jämförelsestudier av Takkonstruktioner med Stora Spännvidder
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
Effektivisering av logistiklösningar : En jämförelse av nya och gamla logistiksystem vid ROT-projekt
A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.
Lean Construction inom en geografiskt begränsad marknad
Syftet med studien är att undersöka om en geografiskt begränsad marknad inom byggbranschen underlättar en implementering av Lean Construction. För att undersöka detta har jag utgått från två forskningsfrågor: vilken inställning de tillfrågade byggföretagen har till Lean Construction och hur de arbetar utifrån ett Lean-perspektiv? Utifrån ett antal grundprinciper från Lean Construction formades en enkät för datainsamling. Resultaten från undersökningen visade att respondenterna som bestod av platschefer/arbetsledare och underentreprenörer överlag tyckte att de områden som tagits upp var viktiga för en lyckad byggprocess och en stor del av respondenterna även arbetade utifrån ett Lean-perspektiv. Enkätundersökningen tog upp nio områden: samarbete, Visible Planning med detaljerade veckoplaner, Just-In-Time, slöseri, standardisering, Kaizen, innovationer, Last Planner med arbetsplanering och Percent Plan Complete från Last Planner konceptet.
Alternativ motorinkapsling
The problems caused by the current engine casing in aluminum for Volvo Buses Corp. are the mainfoundation for this degree project. Lack of maintenance combined with a construction poorlyadjusted for assembly has resulted in the fact that the engine casings rarely get reassembled whenthe service is completed.The degree project has mainly been following ?Olssons.

Hållbart ansvarstagande för ett medelstort byggföretag i Sverige - En analys av värdeskapande aktiviteter som bidrar till hållbar utveckling.
This report deals with activities that from a CSR perspective are considered to create a shared value for a medium-sized construction company in Sweden. The CSR definition used in the report is the European Commission?s since it reflects the valuecreating aspects of CSR, in contrast to the traditional philanthropic aspect of CSR.Companies in the building construction industry have difficulties identifying activities that create value in society and in the company. The aim with the project is to, from a CSR perspective, identify and evaluate value creating activities in a building construction company. The activities will be evaluated with respect to competitiveness and how they can be implemented into an organization.
3-D handlingar, GPS-styrning och VA-moduler- En ny metod för framtida anläggningsprojekt
Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.
Från 2D till BIM i ett trähusföretag : Transition from 2D-CAD to BIM in a timber frame home company
A prefabricated timber frame house previously built by Villafabriken AB has been modeled in Autodesk Revit Architectural, a 3D-program based on BIM-technology. This has been done tosee if it?s possible to produce the publications that Villafabriken demands from the designengineer?s work, and examine which possible extra values that may arise compared to traditional 2D-CAD drawing.BIM is short for Building Information Modeling. Everything is stored in a single database and a change in the project file is automatically updated across the project. BIM provides more than just drawings since information from the model can be retrieved in various ways such as lists and quantity schedules.It was possible to produce the publications that Villafabriken demanded using Revit, but BIM doesn?t only mean a new way of drawing, it also require a change in the company?s process were the information from the model is being used..
BRA Metodik - Balanserad ruttanpassning för mjölkrundetåg i JIT-organiserade monteringsavsnitt
This thesis aspires to construct a routing optimization method customized for Volvo Powerstrain?s manufacturing plant in Skövde, Sweden. In order to enforce Volvo?s own understanding and control of there own organization, as well as optimize the utilization of the in-house tow trains, the BRO methodology where created. The methodology where created from observations of the currents working environment, analysis of order data as well as a comparison with two similar producing factories.
Dynamisk modellering av kärnreaktor
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Huset under och i graven : en studie av fenomenet med huskonstruktioner under gravhögar
The aim for this bachelor thesis is to find an answer for the placement of Migration and Vendel period graves on preexisting house constructions in Sweden. The reason behind these graves being built on their respective places will be analyzed, discussed and compared with similar finds in Scandinavia, where a wide contact net had been established during this time. Different kinds of social and religious meanings and functions with the grave mounds will also be taken into consideration during the discussion and analysis. The actual findings in the graves will be not be a part of this thesis, as the aim is to focus more on the grave itself as a cultural and social symbol for the people, and the values it had, during the time period it was built..

Skärvor av en svit ? förflutenhetens plats i Hammarkullen
The present study examines the demolition of a house on Hammarkulletorget in 1996 and the discourse of Hammarkullen, Gothenburg(Sweden), drawn from the perspective of historicization [?historisering?]. I have examined how the past played role inpresentations of Hammarkullen and how the past affected the decision to demolish a house. By examining which role the neighbourhood?spast time played in the perception of the neighbourhood, the thesis aims at providing a better understanding of howthe past can influence and legitimize major changes in the urban environment.In the early 1980s the image of Hammarkullen as a victim of negative publicity is established and this reputation lives beyond thesimplistic and negative descriptions themselfs.
Upprättande av mall för fuktsäkerhetsbeskrivning : Genom granskning av projekt ur fuktsäkerhetssynpunkt
During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.
Kategorisering av idésyften : En kvalitativ analys av idéer i Volvo Construction Equipment?s idéhanteringssystem
Syftet med detta examensarbete är att på uppdrag av Volvo Construction Equipment hitta en metod för att hantera och kategorisera idéflödet i deras idéhanteringssystem Interact. Den metod som användes var kvalitativ innehållsanalys. Slutsatsen är att metoden gick att använda för att kategorisera idéflödet men att ett material som sträcker sig över många ämnen tenderar att sänka tillförlitligheten på resultatet. Vidare bedöms materialet som detta arbete har producerat kunna användas för att bättre ta tillvara på idéer, vilket uppskattas av Volvo Construction Equipment..
