Uppvärmningssystem - En analys av valmöjligheter för småhus

When constructing a new house many questions appear, from architecture to decisions regarding installations. Sweden is situated in a cold part of the planet and questions regarding which heating system to install face everyone who decides to build a new house. This thesis describes a construction solution of a villa in Kiruna. The extended essay analyzes which heating system is most suitable for the construction. The options are geothermal, district and pellet heating systems.

Förutsättningar och hinder för att använda offentlig upphandling som styrmedel för en hållbar hantering av entreprenadberg

Large volumes of excavated soil and rock are generated in building- and construction projects. These materials need to be transported longer and longer distances due to the densifications of cities. The transportation affects the environment in terms of noise and emissions, but also makes high demands on road infrastructure. To reduce the transport distances an increased responsibility for the excavated rock generated needs to be taken. Responsibility can be increased through an introduction of means of control.

Bergvärme och solenergi i flerbostadshus : En förstudie över Kv. Uppfarten

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.

IMPLEMENTERING AV ARBETSMILJÖLAGENS ÄNDRINGAR, GÄLLANDE FRÅN 090101, PÅ BYGGARBETSPLATSER

In the EU there are EC Directives that Member States of EU should follow. Sweden has undertaken to transpose EC Directives regarding the working environment to Swedish Provisions.  In 4 April 2006, the European Commission had some criticism against the Swedish implementation of the Construction Sites Directive. The Swedish Work Environment Authority has in response to this criticism reworked the Work Environment Act and related provision about building and civil engineering work. The changes came into force 1 January 2009.These changes have resulted in some working methods and even new responsibility subjects must be reviewed. The purpose of this exam project was to investigate if contractors and clients in the construction sector, had have time to update themselves on this front and adapt to these changes.

Konstruktionen av en "invandrare" - I mötet mellan tillskrivandet och behovet av en kollektiv identitet

The way society categorize different people into groups is problematic in the sense that the categorization can seem stigmatizing and have social consequences for those being categorized. Immigrants are one of those problematic categories.The following essay studies this categorization of ?immigrants? based on a governmental investigation of structural discrimination that took place in 2002-2008. The aim is to study the use of the category ?immigrant? and the consequences that follows such a categorization.

Kan ?Gnaget? och ?Stig-Helmer? påverka infrastrukturen? : En studie om turismens påverkan på infrastrukturen

The purpose of this paper is to examine whether, and if so, how tourism effect the construction of a new city district with a stadium in focus. The study is based on a case study of Swedbank Arena and Arenastaden as nearby area. There has been an interest from the writers to study Swedbank Arena and Arenastaden, as it is a current subject, and both of them are under construction, which means that it was possible to see how the process works from the ground up. It has been shown that Swedbank Arena is built up in an entirely new district in which there will be new infrastructure that is tailored to the stadium and the crowd it?s expected to attract.

Nödlösning i fickformat - stående kissande för kvinnor

The product "urinal funnel" for women has fascinated me for a long time. Not only because it solves a practical problem in a simple way, but also because it challenges our definitions of gender and behaviour. This report describes the process of making a new design for a funnel, taking material, ergonomics and construction in consideration. It also includes structuring a launching of the product in Sweden. It starts up with a large amount of information gathering, both by interviewing testgroup-perticipants, but also by researching and evaluating the range of existing funnels.

Kinetisk Keramik

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

Modig eller rar, vad sa far? : En studie om Kamratpostens framställning av flickors och pojkars fritid

The aim of this study was to shed light on how journalists describe the child?s world and what gender labels are used in their descriptions. We wanted to get a better understanding of what happens when gender is constructed.In order to study how gender is constructed, we chose to examine how the children?s magazine Kamratposten describes children?s spare time. We chose Kamratposten because it turns to both girls and boys.

Förbättring av leveranssäkerheten vid Volvo Construction
Equipment Components genom flaskhalsstyrning

Syftet med examensarbetet är att ta fram förbättringsförslag som höjer leveranssäkerheten för transmissioner och axlar vid Volvo Construction Equipment Components (CMP) i Eskilstuna. För att möjliggöra detta har en tydlig bild över företagets situation idag skapats. Enligt kunderna anser CMP vara en av de sämsta leverantörerna, vilket verifierades när den genomsnittliga leveranssäkerheten uppmättes till 30% i den utförda undersökningen. Den dåliga leveranssäkerheten är till stor del egengenererad och skapas genom en ond cirkel av länkade problemområden. Den onda cirkeln börjar med dålig leveranssäkerhet vilket medför svängningar i produktionen som förstärks genom sättet att planera och anskaffa material.

Effektivisering av lagringsplatser. Ett förbättringsprojekt på Mekpart AB

Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

Bättre arbetsberedningar med hjälp av BIM : Hur de kan utformas för implementering av BIM

During the past years Building Information Modelling (BIM), which is a digital way to work, has begun to spread amongst the parts of the construction process. At the construction phase the larger companies has started using the new way to work. This expansion has not been developed amongst smaller companies leading to the purpose of this report, to investigate in which ways the smaller companies can implement BIM by changing their way to work. The thesis is delimited to work preperations with the objective to define how the work preperations should be structured to enable the implementation of BIM. To achieve the objective of the report, information about the subject has been collected by interviews and literature studies.

Passivhus - lönsamt eller ej? : En jämförelse mellan ett passivhus och ett konventionellt hus

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.

Konstruktion av maskin för Tillverkning av sågblad

The saw blade producer, Håkansson Sågblad AB, patented in the U.S. a new blade profiledesigned specially to cut fish and meat. The most important advantage of that blade is that its teethare not set, therefore the material lost when cutting is really smaller. The special geometry of thatprofile made that nobody had found a proper way to produce it before.The goal of the outlined work is to develop a machine to produce these new blades in afeasible way.The research approach of the project can roughly be divided into three phases:1.- Invention and development of a proper distribution of blades to produce a big amount ofthem at the same time.2.- Research of the best production process to produce the blades.3.- Main design of the machine to produce the blades.In the Thesis these three points are carefully developed and studied in the form of the startpoint of a really bigger project. Some tests had been done in order to prove all the analytical ideasand the results obtained had been satisfactory enough to give Håkansson the start point of a bigbusiness.
