This paper, Personal safety when working with weather encapsulation constructions, is focused on weather encapsulation constructions and how the absence of Swedish standards and regulations is affecting the safety for the workers. The usage of weather encapsulation construction is increasing in Sweden therefore the needs for standards and regulations are becoming more and more urgent. The risks involving the rising and the demolition of the weather encapsulation construction and when the construction is transported along its rails are treated in the paper. Since there are no regulations companies have had to solve the safety issues without instructions, the paper regards how the companies have solved this problem without the support of formal institutions..

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

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.

Att företag tar fram kärnvärden som ett sätt att ge de anställda riktlinjer för hur de ska agera inom företaget blir allt mer vanligt, men fyller dessa kärnvärden till fullo den funktion i företaget som de är framtagna för? Syftet med denna studie har varit att ge en bild av hur ett specifikt företag, i denna studie Peab, arbetar med att förmedla sina kärnvärden och hur de anställda uppfattar och förhåller sig till dessa värden. För att få fram viktig bakgrundsinformation gjordes det en dokumentgranskning av det material som har tillhandahållits från Peab gällande deras kärnvärden och hur de arbetar med att förmedla dessa. I denna studie har en kvalitativ ansats valts och det genomfördes sex semistrukturerade intervjuer med två olika yrkeskategorier inom företaget, som i denna studie benämns som chefer och yrkesarbetare. Studiens resultat visar att den information som ges kontinuerligt till Peabs medarbetare skiljer sig åt beroende på vilken av de två ovannämnda yrkeskategorierna de anställda tillhör.

Konkurrensen inom byggbranschen har på senare år lett till krav på lägre entreprenadkostnader och minskade ekonomiska marginaler för byggföretagen. Ekonomistyrningens har därför ökat i betydelse för att ständigt styra byggföretagen mot fortsatt lönsamhet.I Peab skall ekonomin under ett byggprojekt uppdateras och följas upp kontinuerligt av ansvarig produktionschef. Det arbetet ger en god kontroll över projektekonomin, möjliggör regelbundna kostnadsavstämningar samt underlättar upptäckt och åtgärder av avvikelser under produktionen. Det finns styr- och uppföljningsverktyg att tillgå för ekonomiarbetet på byggarbetsplatsen.Grundstenen i Peabs ekonomistyrning är produktionskalkylen. Utifrån en uppdaterad och aktuell produktionskalkyl genomför man regelbundna slutkostnadsprognoser för att stämma av hur byggprojektet ligger till.

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.

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. F, Principkonstruktion, Compendium, Lund?and ?Olssons.

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.

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.

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.

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..

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.

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.

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.

Work Environment problems on construction work sites are very extensive and discussed. The construction industry is one of the most dangerous industries in Sweden. The construction industry occupies about 290 000 employment (2009), and the investment was 250 billion SEK. This report will investigate the issues of the work environment and offer advice on how these can be measured and imporved. The study includes review and analyses of occupational injury statistics, interviews, inspections and audit and review of the literature.
