Användning av BIM-modeller vid kommunikation mellan olika parter

Trafikverket vill ta reda på hur de skaimplementera BIM (Building information modeling) som ett arbetssätt i sinorganisation vid projektering, byggande och förvaltning. Syftet med det härexamensarbetet är att ta reda på hur Trafikverket kommunicerar med BIM-modelleridag och hur man kan utvecklas.Det är få människor i anläggningsbranschen som idag har erfarenhet av att arbeta med BIM. Även i de projekt som jobbar med BIM idag så behövs det alltid en BIM-samordnare som håller i trådarna. För att få ett bra slutresultat så måste kommunikationen i ett projekt fungera bra. En förutsättning för detta är att alla inblandade parter har samma mål med projektet, t.ex.

Effektivisering av kravspecifikationsprocessen

The goal of this project was to make the requirement process at the Swedish Coastguard more effective. The first step to achieve this was done by locating bottle necks in the process with value stream mapping method. The result of this study showed that the biggest restriction in the requirement process was while examining older requirement documents to understand what elements were suitable for the particular project. This was followed by a study of literature, interviews and theory of Lean Production with the ambition to investigate how the requirement process was handled on other companies and how to improve the process on the Swedish coast guard. This led to a number of potential enhancements of the process which later was evaluated. Requirements written by different people in different organizations were analyzed in order to sort out if there were some similarities? which could be used as standard elements in a future standardization of the process.

Vem sa att det ska vara fint? : En studie om tre bildlärares syn på process och produkt i bildundervisningen

Denna studie behandlar begreppen process och produkt. Syftet är att genom ett hermeneutiskt perspektiv undersöka några bildlärares syn på begreppen process och produkt i bildundervisningen på högstadiet. Tidigare har fokus legat på elevers färdiga produkt men idag är bedömningen i bildämnet mer fokuserad på elevers process (Skolverket, 2012:3). Undersökningen genomfördes genom  kavlitativa intervjuer. Intervjufrågorna är förankrade i Lindströms (2002:4-5) process- och produktkriterier.

Goodwill. IFRS3 & IAS36  - ?Big Bang? utifrån en revisors utgångspunkt.

The study aims to illustrate how women victims of male violence in intimate relationships are treated during the legal process and with professional perspective describe what women?s experiences considered to be in the legal process. The study also aims to draw attention to the interventions for abused women during the legal process.The results are based on interviews with professionals in the justice system, and on observations in the courtroom. Overall our results show that abused women are in need of a great quantity of help and support before, during and after the negotiation. The legal process is very stressful for the women.

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.

Elstart Motorsåg

As requested by the company Husqvarna AB, we have developed a prototype of an electrical start device to a chainsaw. This was done through the development of new details in Catia, which has been integrated with existing details. Electrical components have been purchased by HAB electronics. In parallel with the modeling calculations was done, which was the basis for determine dimensions and the choice of an electric motor and gears. Prototype 1 improved gradually and led to prototype number 2, which became the final result.

Implementering av Virtual Design and Construction: en
fallstudie av Veidekke Entreprenad AB

Den svenska byggbranschen står i nuläget inför en stor teknisk förändring, införandet av Bygg-informationsmodeller(BIM)/Virtual Design and Construction (VDC) i stor skala. Branschens olika aktörer ser olika vinster med implementeringen som kommer påverka hela byggprocessen, från projektering till förvaltning. Denna studie fokuserar på organisation och process i projekteringsskedet och grundar sig på en fallstudie av Veidekke Entreprenad AB. Företaget har implementerat VDC i delar av organisationen och i nuläget, efter lyckade pilotprojekt, utvidgas satsningen och implementering görs i större skala. Studiens syfte är att kartlägga Veidekkes VDC-mål och strategier, för att därefter studera process och organisation i projekteringsfasen och hur de bör utvecklas för att skapa goda förutsättningar för att VDC-målen ska kunna uppfyllas.

Att datorisera ett bibliotek: datoriseringen av skolbiblioteket på Sunnerbogymnasiet i Ljungby

The purpose of this paper is to describe methods to computerize a library and to compare theory with a process in a school library. The case study is based on a school library called Sunnerbogymnasiet which is situated in Ljungby. My questions are;- Which methods are parts of the process to computerize a library?- Which methods are used in the process in Sunnerbogymnasiet?- What does the practical process look like compared to the methods described in theory?In the paper I present the methods in the process according to the studied literature and compare these with a process at Sunnerbogymnasiet. The most significant result is that cooperation between the school library and the community library was the most important reason for the choice of library computer system.

Industriellt köpbeteende av utlandsresetjänster

The purpose of this thesis is to examine the organizational buying behaviour in the purchase of travels abroad. We have conducted a case study of two companies, one medium sized and one larger. Our empirical studies have shown that the companies? buying process is divided into two types, the process of recruit a new travel supplier and the process of a straight rebuy of a regular travel service. In the recruiting process we found that the evaluation process of the purchase is an ongoing process that contradicts estab-lished theories.

Jämförelse av verklig och modellerad elproduktion från en solcellsanläggning : En utvärdering av två simuleringsverktyg.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

Segmentering och klassificering av LiDAR-data

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

Jag vill, men hur? Ett utforskande av den kreativa processen.

I want to, but how? My work is a research of the creative process. I have asked myself how ideas take form and how materials can become bearers of ideas. The work has been treated as an action rather than an object. The result shows my research and my interpretation: the process and result are the same..

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.
