Visionen BIM
IT-användandet i byggbranschen har banat väg för nya, effektivare arbetssätt och det finns visioner om hur det ska fungera. Syftet med vårt examensarbete är att ta reda på byggbranschens användande av, och vision om BIM. Vad är BIM ? Building Information Model?Kort beskrivet är BIM en modell där all information för ett byggprojekts hela livscykel kan hanteras. BIM förenklar det fortlöpande arbetet genom hela byggprocessen genom att tillhandahålla information om projektet som är relevant, uppdaterad, integrerad, fullt koordinerad och av hög kvalité.
Lönsamhetsbedömning av utökad MR-kapacitet på Karolinska Universitetssjukhuset
This thesis analyses how a radiology department at the largest hospital in Sweden, Karolinska University Hospital, most profitably could expand its capacity for investigating cancer patients using magnetic resonance imaging (MRI). The queues today for patients waiting to be scanned are long, which delays the start of cancer treatments. Meanwhile the hospital has a budget deficit of half a billion SEK, which make any expansion hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these.
Värmeåtervinning ur spillvatten i befintliga flerbostadshus
Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.
Ombyggnation av ett stall för bundna mjölkkor till boxsystem för rekryteringskvigor
To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..
Toleransproblem vid produktion och montering av prefabricerade betongelement
The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.
Analys och produktionsförbättring på monteringslinan Vensafe
This study is preformed at Westbaltic Components placed in Töcksfors Sweden. Themain target in this study is to make one of the company?s assembly lines better andmore effective. The assembly line constructs vending machines for different stores allover Europe.It will contain tobacco, snuff, cigarettes and shaving blades and many more similarproducts.The first step in our study is to locate the daily problems and find out a good way toreduce them and make them disappear. A good way to do this job easier was toconstruct a visualizing board.
Simulering av elektriska förluster i en vindkraftpark : Utveckling av programvaran Wind Farm ElectricSystem Calculator (WFESC)
When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.
Etableringsstrategier för spannmål : en studie av investeringsbeslut i maskinsystem
In order to produce grain in an economically rational manner numerous decisions have to be made. One of these decisions is what tillage system to use. The cost of the tillage system is a large part of the total cost in grain production. Different tillage systems result in different distribution of fixed costs, operating costs and timeliness costs. The price of the produced grain and cost of inputs also affect the best way to produce grain.
Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :
Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.
När backa inte längre var ett alternativ : Genomförandet av Arenastaden i Växjö
This thesis suggest an explanation for is how it is possible to understand that the large arena project in Växjö grew to cost sums of money that initially in the project not would have been an alternative to discuss, how goals changed and how the institutional environment changed the prerequisites of the project. As empirical part of the research, to describe and analyze the project, the municipality?s documentation of the project have been analyzed and semi-structured interviews have been made. Theoretical perspective is taken from the neo-institutionalism in sociology of organizations and change, and theories of the complexity of large projects with major symbolic value and importance. The project starts with the municipality?s investment and cost to be hold back, defined as a necessary condition in order to fulfil an ambitious drive towards new sport arenas. Eventually the necessary condition was abandoned and the arenas were built with the municipality responsible for the investment, cost and risk in the project.
Konflikten mellan bevarandekrav och tilläggsisolering : The conflict between conservation requirements and additional insulation
Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.
Assessment of food retail business sustainability : the case of Konsum Värmland
Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.
Automatiskt kabelmärkningssystem
Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.
Konsten att enas under ett varumärke : Intern varumärkesuppbyggnad på Nordiska Kompaniet
Purpose: The purpose of this study is to examine how a company with a single brand is perceived as uniform, as well as how they use internal brand building to reconcile various competing actors within one brand. Furthermore the aim is to examine how staff, through internal brand building processes, perceives and identifies themself with the values of the common brand. Method: A case study with method triangulation was conducted at Nordiska Kompaniet department store in Stockholm. Quantitative data through a questionnaire survey with employees combined with two observations. Qualitative data was given through an email interview with a responsible manager of digital channels and PR from NK AB.Theories: This study has used the following theories; Destination marketing, Corporate brand, internal branding, corporate identity, corporate culture, brand value, service brand values, brand citizenship behaviour.Conclusion: This case study of NK has shown that internal branding building in a department store is a comprehensive work, which all involved must have a unified perception and understanding of the brand, in order to successful unite under one brand.
Färsk ved till Hallstaviks pappersbruk :
Hallstaviks papermill is an industry plant within Holmen Paper. Hallstavik is a mechanical
mill and produce newspaper and journal paper. During year 2000, Hallstavik used
approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the
production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.
