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.
ENERGI- OCH KOSTNADSEFFEKTIVAMATERIALVAL I VÄRMESYSTEM : En jämförelse av rörmaterial i vattenburna värmesystem
The thesis aims to compare differentpiping materials in heating systems interms of cost as well as to illustratethe impact of energy characteristics ofdifferent materials over its servicelife. The methods used for costcalculations regarding piping are alsoto be examined to highlight thedifferences between template basedcalculations and more carefully executedones. The work is delimited to discusspipes of steel, copper, plastics andcomposites. The aim is that the resultcan be compiled to illustrate the prosand cons of various materials whenevaluating investments.The main object of the survey is part ofa heating system in the office-block KVSommaren located in southern Stockholm.The configured piping system is designedwith the mentioned piping materials andis used to make up the data for flow andcost calculations. The differentmaterials are calculated in both aconventional manner with a supplementarycost for additional fittings and with amore accurate quantification of thecomponents.
Trädgårdar på tak- och gårdsbjälklag :
The purpose of this thesis is to collect knowledge of techniques and materials for planning roofgardens.
Gardens built on top of buildings is not a new phenomenon, already in the beginning of the century architects were experimenting with roofgardens. During the Modern Era roofgardens appeared as a part of the design and worked well together with flat roofs and the ideas of light, air and greenery. Today the most common kind of roofgarden is on a ground-level joist that hides parking or other underground functions.
The most important difference between planning a roofgarden and a garden on the ground is the limitation of the load of the roofgarden. Plants, paving-material and equipment must be chosen with this in mind. A light and thin layer of soil demands plants with small needs for water and nutrition.
VISUALISERING AV KATALOGHUS -med ADT och VIZ Render
The aim of this final thesis is to make it easier for the customer of a new designed house to get a picture of what the house will look like inside before it has been built.A method, which can be applied by any construction company who likes to visualize there buildings, has been designed and tested. One works after a regular design planning which is transformed into a three dimensional model of the house. In a rendering program, materials and surfaces are chosen for the model and then a picture of the finished product is made. The programs used for this work are ADT 2006 and VIZ Render.To evaluate the use of this method I?ve chosen to cooperate with LB-Hus which is a housing company that is specialized in building detached houses.
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..
Nollavräkning av entreprenadprojekt: Teoretisk grund och praktisk betydelse
The purpose of this study is to investigate the method called zero recognition that is used in accounting for construction contracts when the outcome is uncertain. When this is the case it is hard to make the necessary estimates needed for the percentage of completion method to be used. Both the meaning of the method from an accounting perspective and the practical importance and purpose of the method is investigated. The method used for this study is the qualitative one and the deductive model is used to relate the theory with the empirical research. The theoretical background consists of accounting theory and theories about individuals, companies and markets.
Miljöval för byggnadsmaterial : Med häktet i Helsingborg som referensobjekt
Today's climate and environmental issues have now been up for discussion for quite long. Various environmental measures have been taken, but it is not always certain that those measures actually are for the better because of the complexity of our environment. Therefore, studies of whole life cycles are very important even if they are time and resource intensive.Real estate accounts for 15% of global carbon emissions, but also affects our environment in many other aspects. In Sweden this number is even higher. About 30 % of its carbon dioxide emissions originates from building sector and changes are therefore of great importance.
Risk eller Resurs: En studie av hur riskbegreppet konstrueras i den svenska kärnkraftsdebatten
Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.
Skyddsombudets Roll : En undersökning av skyddsombudets säkerhetsarbete på byggarbetsplatsen
Safety in the construction industry has become a question of top priority in recent years. Despite a massive investment of time, money and knowledge, the occur-rence of fatal accidents in Sweden alone is around one a month.The purpose of this study is therefore to improve the safety on the construction site. By an examination of the role of the safety agents and their cooperation with the construction workers and supervisors as well as examine how safety agents can improve safety on the construction site, which is the goal of the study.Four questions were formulated based on the purpose and the goal of the study.The methods used to answer the questions were a questionnaire survey, multiple interviews, a literature review and a document analysis.The report describes the safety agent?s role as a complex one with many different tasks. The role of the safety agents is regulated in the health and safety law, but it can sometimes be difficult to interpret and the agents can therefore interpret their role differently.
