Tvåsamhället : Om att förhålla sig till normer som skaver

This study focuses on single peoples construction of their lifes in relation to normative heterosexual coupledom. It is based on five interviews made with single women and men at the age of 24 to 51 who live by themselves. The queer theory which puts the heteronormativity in question is used as a theoretical framework. Discourse psychology functions as an analytic approach. It focuses on the use of language in the construction of reality in a world of determinant discourses.

Projektorganiseringen som drivkraft och hinder för industriell förnyelse i byggindustrin : en fallstudie av Skandionkliniken

Understanding how innovation and renewal occurs in an industry is important for how to manage technical development for individual companies. It is also important for creating a beneficial industrial context for renewal, from both a political and an industrial perspective, in which new solutions can arise and spread through the involvement of several actors of the industry. How innovation and renewal occurs in the construction industry in Sweden is however viewed differently. One challenge that has been pointed to is that most of the work performed in the construction industry is organized in projects, which in turn should affect how innovation and renewal can be achieved. The aim of this thesis is to provide an understanding of how the project organizing in the industry affects innovation and renewal. This is executed through a case study of the construction of Skandionkliniken, a proton therapy clinic, and by using an industrial network theory that challenges the traditional view of how innovation is achieved.

Kontroll för ökad kvalitet - mallar för kontrollplan-PBL, egenkontroll samt riskanalys

There are problems with poor quality, poor scheduling and poor working climate in the Swedish construction industry. Many parts have been involved, trying to solve the problem.This spring a new planning and building-law becomes final. In this law, the requirements set on the controls are greater. Hopefully this will lead to fewer construction errors. The requirements set on the working environment have also increased, forcing consultants and contractors to focus on safe workplaces.For each project requiring a building permit, an inspection plan has to been drawn.

Kartläggning och visualisering av riggkonstruktionsprocessen : Fallstudie från Scania

Mapping a process enables a greater understanding of the work, and is standard to evaluate and improve a process. This thesis is conducted at Test Bed Mechanical Design at Scania in Södertälje. Test Bed Construction is a complex process, characterized by a large amount of creative work, technical challenges and coordination between different people and different organizational functions.The aim of the thesis was to identify the Test Bed Construction Process and to develop a visual model of the workflow that also served as support for the engineers in their daily work. During the mapping process, comparisons were made with previous research in lean product development to identify process improvement.A literature review on process mapping and process visualisation resulted in a method for process mapping. The study showed that research on process visualisation is neither structured nor well defined.

Småhusproduktion : Utvecklingsmöjligheter hos JM AB

The Swedish building contractor JMRegion Öst would like to to investigatethe possibilities of developing andstreamlining the production of singlefamilyhouses. JM are producing singlefamilyhouses with prefabricated framesat a rate of about two houses per week.During construction, the different tasksare performed by JM?s own productionstaff but also by varioussubcontractors.When examining the schedules of recentlyproduced projects, it appears that allthe houses are more or less completedeight weeks before the customer moves into the house. During those eight weeksseveral operations are conducted such asinspections, installation of appliancesand cleaning procedures. The inspectionperiod constitutes between 25 and 35% ofthe complete construction period.By conducting interviews, it has beendiscovered that this final phase is anessential security buffer for delays anderrors that often occur.

Internationell Upphandling av Byggmaterial : En studie över materialimportens potentiella tillämpning hos medelstora och stora byggentreprenörer

High housing- and construction costs is a fact in Sweden today. Prices on building materials more rapidly than producer price index for industrial goods. Prices tend to rise during market boom but does not adapt during diminishing demand. The effects of fading demand can rather be deduced through discounts and quotations. During 1992-1998 when the Swedish construction sector found it self in severe crisis the prices of construction materials kept rising more rapidly than PPI for industrial merchandise.

Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

Hjullyft

The graduation essay has been carried out in co-operation with Kalmar Industries in Lidhult, Sweden. The purpose of our essay was to develop a complete construction solution on a hoist that could lift a laying wheel, lift it up and then turn it 90 degrees. After that the wheel shall be placed in a special holder.The background of the essay is a record of reports of damage wheels when they been incorrect lifted with a forklift. The hoist shall be used together with the same forklifts that manage the wheels today. Together with our instructor at Kalmar Industries we developed a requirement specification and from that we got free hands.However this was not the main task from the beginning, then a simular hoist should be develop but used directly in the assembly workshop without using a forklift.We started to find principle solutions that later was evaluated against the requirement specification.

Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus

The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.

Elektrisk skorstenständare

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.

Erfarenhetsåterföring :  

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..

Effekter av nya PBL : En studie av processen från handläggning av bygglovsansökan till slutbesked

It has now passed two years since the new site- and construction law, PBL, went into force. It replaced the previous PBL applicable since 1987, and it involves relatively large changes in many different areas of the construction sector. The ambitions of the new law are for instance to simplify and clarify the legal text, increase efficiency in the permitting processes and improve the quality of construction. To achieve this, a variety of changes was made. Some of the most important are: inserted deadline in the processing of building applications, extended assessment of building applications, revised rules about controlplan and quality manager, a certificate is required to start and end the project, an additional meeting is inserted and the construction management of the municipalities will have to do a mandatory visit at the work scene.

Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Konstruktionen av den japanska ledaren: En studie av kvinnans roll i det japanska företaget

Japan is the first industrialized country that is experiencing the threat of a rapidly declining and aging population. This has shifted the focus and the limelight is now on the matter that for a long time has been ignored. That is, the Japanese women?s situation in the society. This thesis seeks to point out the relevance of gender in the construction of leadership in order to get a deeper understanding of the Japanese women?s situation today.

Smörjning Av Lager

The work thesis was performed at Assalub a company which is situated in Åtvidaberg. The company works with developing, manufacturing and marketing equipment for handling of lubricants for light and heavier industry. The work thesis it is based on a inquiry Assalub got from MacGregor which is a company within cargo solution, from port to offshore system.For unloading grain and other material from the ship cargo it is used combined inlet feeder and screw conveyor, there the inlet feeder is drilling down through the cargo and feed the screw conveyer with material to further destination. At the bottom of the screw conveyer and the inlet feeder there is a bearing that keep the parts together. However the lubrication of the bearing must be made manually.
