Temperatursprickor i ung betong : Utvärdering av projektering och utförande av åtgärder, samt utveckling av dimensioneringsmetod för kylsystem

The report contains three parts. The first part is a summary and overall presentation of thermalcracks and preventing measures against such cracks. This is a theoretical part where theinterested designer can get acquainted with various alternatives, be guided to more detailedliterature, and receive some practical information regarding the design of the respectivemeasures.The second part deals with calculation of the risk for thermal cracks and design of water coolingas a limiting measure. Two complementary methods are reviewed for efficient calculation:?the handbook method CraX1(by Lulea University of Technology) is used for quickverification?finite differential analysis in the calculationtool ConTeSt Pro for more precise projectingHere is also presented a development of existing standards through design of the cooling systemby means of the Bernoulli equation.

Försäkringsplikt i kommersiella entreprenadavtal

Construction projects are generally designed as a general contract or a complete contract. In a general contract the commercial contract that is being used is AB 04 and related advice and instructions, AMA AF 07. In AB 04 there is an insurance requirement that stipulates that the contractor shall take all risks and liability insurance for the contract where the client must be co-insured.Construction law is almost exclusively regulated by the various standard contracts, one of those is AB 04. The Construction Contracts Committe is an organization that has published the standard contracts in this area of law and also the advice and instructions to help the parties to understand the agreements. The insurance requirement occurs in an area of law that is complex and the meaning of the concept is not entirely clear, nor which of the parties? interests and responsibilities that are covered by the types of insurances that are provided by the insurance requirement.

En marknadsundersökning om regelvirke : kvaliteter och kunduppfattningar

Today there is a widespread opinion that the woodmarket and the forest industry are dominated by a traditional way of thinking and not adapted to the customers of today; a lot of products are produced purely on routine. Also, there is a demand for improving the quality of sawn woodproducts. AB Karl Hedin wants to sort this out by increasingly adapt their products to the demands of the market, i.e. through introducing a short wallstud of standard length, "Hedinregeln". At tirst, the wallstud will be produced in lengths of 2,70 m and of guaranteed quality.

Rotationsdämpare med integrerad fjäder

This final thesis is carried out at BAE Systems Hägglunds in Örnsköldsvik. The mission was to construct and integrate a new semi-active damping unit in the terrain vehicle BvS10. Questions that came up during the process, among others, was how to mount the damping unit to the vehicle in a flexible way without exposing it to unnecessary wears.A generation of the concept is made in 3D using CATIA V5 of a possible solution to the problem. The idea is to weld the unit to the skid girder which is one of the main constructions of the track system. In this way the damping unit will come closer to the track system, which will partly protect it from impacts from below and minimize current problems with breaking forces in the torsion shafts.The complete construction was then analyzed, first by theoretical calculations and then with the FEM-tools in CATIA V5.

UTFACKNINGSVÄGGAR : En jämförelse mellan platsbyggda och prefabriceradebyggmetoder

In conjunction with today?s increasing competition within the construction sector, more pressure is being placed on building contractors. Efficiency and improvements are necessary but without impairment to an ergonomic and safe construction site. This in is in order to reduce the construction costs and time but to retain the ability to deliver a high-quality contract.Various methods and prefabrication degrees are used, depending on the project's requirements and conditions. This analysis sets out to investigate and exhibit what qualifications are important when choosing a construction method for curtain walls.Advantages and disadvantages with each method have been analyzed and recommendations have been given to show when different methods are best suited.

Stadsklimat/Gatuklimat :

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

Riskutfall i entreprenadprojekt inom NCC Construction Sverige
AB

NCC Construction Sverige AB är ett byggföretag inom NCC AB. Företaget är verksamt inom hus- och anläggningsbyggande, bostadsbyggande, bostadsutveck- ling samt service i Sverige. År 2004 hade man en omsättning på cirka 17,3 MDR SEK och antalet anställda var cirka 7 600. I varje byggprojekt finns alltid olika risker, vissa får större konsekvenser än andra. Ansvars- och entreprenadskador som inträffar i projekten kostar mycket pengar för NCC Construction Sverige AB.

Observationer av PPU i praktiken och teorin: Konsten att inte planera med luft

The construction industry is often criticized to be an industry of narrowness and slow of change. The traditional construction process is considered to create gasps of inferior quality, delays and increase of disputes. Meanwhile, productivity is lower compared to other industries and the prices are increasing. In this debate, it has been assumed that the reported figures are monitoring a reflection of reality, but there might be an error in the statistics which suggests that the focus is at the wrong place. A study of the monitoring and the measurements of the results are to consider, instead of spending time and resources on issues and actions The Last Planner System is an executive planning tool which creates a predictable workflow and creating value throughout all the different stages.

"A huge, tenacious lie" : framställningen av makt i Helen Zahavis författarskap

This study concerns the complete oeuvre by the British author Helen Zahavi: Dirty Weekend (1991), True Romance (1994), and Donna and the Fatman (1998). Her novels are here read as a trilogy dealing with the dialectics of gender and violence in 20th century discourse, drawing on theories of how the construction of subjects is produced by power, of the relation between power and sexuality.The heroines of Zahavi?s novels try their best to move about in a world where their freedom of movement is limited to their female identity. In Dirty Weekend the protagonist tries to shoot her way out, claiming revenge on every man that is forcing himself upon her. She gains some freedom of movement by refusing subordination, but does not really change the order of power.

När spelen blev farliga: konstruktionen av dataspel som ett socialt problem i svensk press 2000-2006

This essay focuses on the construction of so called "computer game addiction" or "computer game abuse" in the Swedish press during 2000-2006. During this period computer game addiction went from an obscure phenomenon to a legit reason for the involuntary commitment of a fourteen-year-old.The study's theory is based on several social constructionist ideas. Kitsuse and Spector's theories about constructing social problems as claims-making activities are used for understanding the actions of the individual and groups involved. Hewitt and Hall's article about quasi-theory is used to explain the construction of explainations for the new social phenomenon. Blumer's five-stage model is used for categorizing the construction of the new social problem.

Konstruktion av upprätningssystem för CICLoPE

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

Transit Objekt

Transit Objects In the Master Essay I argue around two existing levels in the works presented at the graduation exhibition. On the one hand, it is about influence; on the other hand it is about the phenotypes of purpose-ness. In the introduction, I describe the relationship between the shapes that I have come to call Transit objects, and their on the one hand ideological superstructure; on the other hand, the different aspects of their shapes regarding the imitation I, in creating the objects, performed. In the case with the objects shape-aspects, I stand on the thoughts that I found during my bachelor's work, that is, to express the phenotypes of purpose-ness.When it comes to influence, I speculate about how linguistics, and particularly a branch called neuro-linguistics, illustrates how the arguments that make up our world can be transformed. I use a meta-model and a conversation model as a tool to illustrate this. When I, like that, illustrate the plasticity of meaning, and cognition, I note Catherine Malabous taught (in her book What Should we do with our brain?) on the plasticity of the brain in relation to the neo-liberal systems of capitalism. She argues for how the brain has come to stand model for the organization of different types of networks. I hint the link to a future scenario where the desire to influence takes new forms and uses the latest brain research challenges, more specifically the use of ultrasound for the treatment of pain and other similar conditions. This also can be used as generating various types of seizures, pleasant or unpleasant.

Skiftarbete i byggindustrin och dess värde för aktieägarna

The foremost objective of business organizations is to generate value for shareholders and to opt for strategies which optimize it. Hence it is of key concern for business leaders to appreciate how operations best are run to maximize value creation. This study explores how financial theory can reveal the link between one particular business strategy and the corresponding effect on shareholder wealth. The question in focus is whether construction companies can enhance their value creation by implementing shift-work to increase the weekly production rate. The thesis particularly targets apartment block projects in Sweden and has the construction company Peab AB as primary object of study.
