A qualitative study was conducted at project managers who worked in the construction industry and events industry. Seven interviews were conducted, four in the construction sector and three in the events industry. Respondents are active as project manager in Värmland and Närkes counties.
Jämförelse mellan BKR/BSK och Eurokoders behandling av utmattning i traversbalkar med tillhörande svetsfogar
This report has been performed for WSP Construction Design located at Arenavägen 7 in Stockholm. WSP Construction Design is one of the leading departments in Sweden in construction solutions regarding everything from building construction to industrial building. Great competencies regarding steel, wood and Concrete constructions are available within the department which is well sought.Crane girders used in the industry are exposed to large loads that vary over time that includes instantaneous lifts and the crane girders movement which lead to the phenomenon fatigue in the crane girder and its ingoing welds. A control of fatigue needs to be performed after a certain lifespan measured in time which in turn is converted to a number of loadcycles. When the number of loadcycles amounts to a greater number the input welds resistance will have been reduced and the rate of utilization thereby increased.

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.
Kartläggning av materialflödet i Peabs försörjningskedja till byggarbetsplats med SCOR
The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.
Redesign of an existing apartment block in Kv Preussen to passive house
Passive houses are a relatively new concept in Sweden and by that it is meant a house without a traditional heating system. The most acknowledged passive house project is the terrace houses in Lindås, Gothenburg, which we have used as a reference. This project concerns a square apartment block. So far, no square apartment block has been built as a passive house in Sweden.The common opinion in the construction industry is that it is not economical to build extremely energy efficient houses. With Peab as commissioner our task was to investigate if that is true, if regarding the construction of a multi storey house as a passive houseMidroc, now owned by Peab, constructed in the block of Preussen in Jönköping during 2004-2005 four houses, with 132 apartments distributed on seven floors.
Projektering av ett småhus med fördjupning i uppvärmningssystem
This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

REDOGÖRELSE FÖR SPRICKARMERING FÖR KONSEKVENT DRAGNA BETONGPLATTOR PÅ MARK : Analys av skillnader mellan BBK 04 och Eurokod 2 med tillämpning av svenskt och danskt nationellt annex
In this diploma work the approach of determining the required amount of reinforcement in slabs exposed to pure tension is processed, on behalf of Ramböll Uppsala. It is a well-known problem in the industry that there are uncertainties in the determining of the amount of crack reinforcement, especially for structures exposed to pure tension. Cracking caused during the time of dehydration in concrete slabs is the most common defect according to statistics made by CBI[1], which provides numbers as high as 35 % of all the defects caused on slabs are generated by cracks. Comparisons between Sweden's former national standard BBK 04, Building Regulations for concrete structures due to restrained forces of shrinkage, and the current European standard Eurocode 2 are carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed.
Vårt liv, vår fritid, våra förebilder, vår framtid och där vi bor
Few studies enlighten the problem associated with the dialectical relationship between adults and adolescents and how that affects the construction of identity for adolescent?s, in relation to two areas that are closely bordering to each other but differs socioeconomically whereas one area is much weaker on resources than the other. These two areas is Högberget and Haganäs, which are situated in a larger city in Sweden.For us to be able to enlighten this problem we have chosen to use an inductive research approach so that we can explain how adolescents construct their identity and how the organized spare time, in addition with the influence of adults, impacts on adolescents construction of their identity.Therefore we have used interviews as method, both group and individual, so it can regulate which theories that influence our study. The two theories that wires through the entire study are firstly Peter L. Bergman and Thomas Luckmanns theory on social construction where the idea is that the human being is an active social being that constructs its own reality.
Hur påverkar gummigolv i grisningsboxen suggans liggtider, liggbeteende och hennes tid för att lägga sig?
In the farrowing pens the amount of bedding material and the quality of the concrete floor has a huge impact on both the sow and the piglets. In this study imbedding of
rubber flooring on the solid area in the farrowing pen was used to see if it had any effects on the sows lying behaviour when compared to concrete. Another important
aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally
conductive effect then rubber which can affect the sow?s chance to cool down.
"Ibland tror jag man kan ha en dubbelmoral inom sig själv..." : - En studie om gymnasielevers förståelse av jämlikhet på en principiell och konkret nivå
The purpose of this study is, by groupinterviewing students in upper secondary school, to investigate students comprehension of equality on a principle level and a concrete level. The questions at issue are as follows; how is the comprehension on respective levels described and is there any difference or similarities between the two levels? Further more, this study also aims to end with a discussion regarding the result from the mainpurpose in relation to the educational environment. In my conclusion there is to be find a certain difference between the comprehensions of equality on the two levels. The conception of equality is in the beginning principled and there is no exception from the worth of every individual but however, when the conception is brought out in reality it gets depended of its context and the comprehension for equality becomes more dynamic. The project will be completed with a discussion regarding the results in relation to the educational environment. .

The aim of this study is therefore to investigate how strategic and cultural factors affect the potential for Swedish companies to operate on the Chinese construction market. The theoretical framework of the study consists of Porter?s and Kotler?s theories about strategy, and Hofstede?s, Bjerke?s, and Daun?s research about different cultures.
Energieffektivisering av arbetsbodar på byggarbetsplatser
Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.
