Konstruktion och design av arbetsplats - för kablagemontör
This degree project has been performed with Mega Teknik AB in Landskrona. The project has resulted in a workplace for the cable installers of Mega Teknik. The workplace contains a workbench and a cart.The first stage in this project was to make an analysis of the current workplace to identify the needs the installers had.The different principle construction proposals of how the workbench would look like and which functions it would have was made during brainstorming, in groups and alone. These proposals were compared against each other using a functional analysis that has been put up to get the principle construction that fulfilled most points in this analysis.The proposal chose for further work was a cart and a bench with a module intends, the table got a formulation that creates a better reach for the installers.This proposal was generated in Catia V5 to get a better overview of the suggested proposal.During the primary structure phase drawings over all the products were made and the components were chosen. Calculations were made and the product got the dimension required.
"Gör om min tråkiga rullstol" : Framställningen och förekomsten av hbt-personer, invandrare och personer med funktionshinder i livsstilsmagasin
The purpose of this thesis was to study how four swedish lifestyle magazines: Veckorevyn and Cosmopolitan for women, King and Café for men, represent three groups of people and how often these people appear in the magazines. These groups are HBT, homosexuals, bisexuals and transsexuals, disabled and immigrants. The years we studied were 2007 and 2008.Our main questions were: How often do the three groups appear in the four magazines? How are the groups represented? In order to answer these questions we used a qualitative analysis. We used tools from semiotics, narratology and discourse.
Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab
ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.
HÅLLBART BYGGANDEMED HJÄLP AV BIM : Effektiva energianalyser och LCC
The society strives for sustainable development, in the construction industry it is expressed through sustainable building. Energy and LCC analyzes increases the ability to make conscious decisions in the process. A problem in the construction industry is that energy and LCC analysis is not used to the desired extent, as they are perceived as complicated and time consuming. The report aims to achieve a more sustainable building through increased use of energy and LCC analyzes.The goal is to show how BIM can be used to improve the efficiency of the energy and LCC analyzes.The study was conducted with a literature review and a case study to answer which information that is required in a BIM model to perform energy and LCC analyzes. The study also shows which software can be used in BIM based energy and LCC analyzes and how the analyzes can be carried out efficiently.The result shows that effective analyzes may be performed if the BIM-model contains the relevant information for making analyzes.
Offentlig upphandling : Skillnader i de obligatoriska kraven i större och mindre kommuner.
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Ensamkommande flyktingbarn i media : - en diskursanalys
This research intends to study the media's representation of unaccompanied refugee children on the basis that the media has a power in the construction of society. The focus is on whether children's vulnerability and needs are presented in the media and whether the children?s voices are heard. It is also of interest to study the agents that speak in the media concerning unaccompanied refugee children. The study is based on a theory that social reality is a construction of interaction between individuals and groups. Furthermore the study also incorporate the idea that the media, through its control of language, has power to create discourses which may affect the way different groups in society are looked upon.
PReklam? : En kvantitativ studie som undersöker vad gymnasieelever i årskurs 3 förknippar med begreppet PR
Background and aim: Media development and digitalization has expanded the PR industry's working area. More participants are on the media market and it is becoming more and more difficult to define what PR really is and what the PR agencies/departments really do. Is PR marketing, information, event marketing or maybe propaganda? We believe that the complexity to define the term PR can lead to a loss of critical approach to the business, especially among young people. Has the PR industry managed to eliminate their negative image among students in upper secondary school and what do they associate with PR today? The aim of this essay is to examine what a selection of students associate with the term PR and if they are critical to the PR industry or not.Method/Material: The method is a quantitative survey.

Kunskapsdelning i byggbranschen : Delningsprocessen i Skanskas projektorganisation
Introduction Knowledge has come to be an increasingly important factor for both individuals in the labor market and companies in competition. When a person leaves an organization the knowledge often follows, and a knowledge gap is created. When knowledge is shared within an organization, the individual?s knowledge is available for all members of the organization. Knowledge can thus be converted from human capital to structural capital.
Byggfel på plåttak : - Bristande kommunikation eller bara slarv?
The mistakes and failures on the roof are noticed during inspection of the construction, many of the commentaries are recurring. A contractor should only need to get a commentary once and then learn from the mistake. It has in this study been brought to light that the solution is not to tell the contractors to "stop slattern", it is more complicated than that. Today, the biggest problems are found in leadership, communication, feedback of experience and that the entrepreneurs take too little responsibility.To minimize the amount of commentaries all contractors need to work with a clearer leadership where the leader is both respected and appreciated. The leader must in an effective way be able to convey all the information to all employees.
Ett aktivt beslut att renovera passivt : En ekonomisk jämförelse vid upprustning av miljonprogrammetsflerbostadshus
As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to conventional houses.

Tätskikt i klimatskal : En studie av byggentreprenörers arbetssätt
As energy prices skyrocket and the environmental issues become more frequently debated, interest in energy-efficient buildings has increased sharply in the past decade. Because of this, the interest to achieve high air tightness in building envelopes have once again awakened, due to a good air tightness contributes to lower energy consumption in several ways and to a healthier indoor environment.As the regulations for energy consumption and controls of achieved air tightness has tightened considerably in recent years, the work regarding sheets for air tightness changed significantly for construction contractors. This thesis includes a study that aims to detect what kind of manuals, recommendations or instructions contractors working according, and how a number of randomly selected construction companies in Halland, Sweden, are dealing with the matter of high air tightness of the building envelopes. The study also includes a knowledge inventory of supervisors, site managers and skilled workers, and what their opinions and attitudes are like towards work regarding the sheets of air tightness. The results have been compared with a similar survey dated to 2004, conducted by the SP Technical Research Institute of Sweden in collaboration with Chalmers University of Technology.
