Konstruktionslösningar och deformationer i tre Östgötska medeltida sockenkyrkor
The purpose with this report is to illuminate the construction solutions and the deformations that could exist in medieval parish stone churches. But also to increase the writers understanding how activity forces effect the construction of the churches. With help from literature and a practical study, containing three churches the writers have collected the material that the conclusions and discussions are built upon in this report. The construction of the churches consists of three parts, the wall, the roof and the vault. The construction solutions are similar in the churches disregard of the roof, where the roof trusses are different.

BIM Building Information Model : Hinder & Drivkraft
The construction industry is a costly business such in respect of capital for most construction defects which then require rework, tear down and rebuild again. This study is meaningful awareness of tools that can reduce this best through communication and information sharing between the parties. The construction industry is known as temporary projects organizations, where the construction project consists of several actors who have to communicate and share information between them to avoid mistakes later in the build time. These actors are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to create a routine for the association and the shattering of these actors. To implement such behavior using a tool such as BIM in the industry whose size perhaps is indescribable may be a very hard task. BIM (Building Information Model) could be seen as the solution to this problem because it acts as a portal where the actors involved must sign in and communicate, share information, and eventually create a behavior, a routine for this association and division of the actors following the end of the project. The technology could help the involved from the beginning of the project, already in the model stage, break down and prevent any construction barriers when the building has been placed in the works.
Logistik
The construction industry develops at a high pace today. Because of this the construction companies has to rethink and try to develop at the same pace. One of the biggest challenges in the construction industry today is to improve the logistics since improved logistics leads to lower costs. This is something that the construction companies have started to realize and they are beginning to invest more money in order to improve the logistics. It is especially important to have good logistics when the conjuncture turns for the worse.
Metodik för utmattningsberäkning av svets i vibrationsmiljö
In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
Utfackningsvägg i fältfabrik : en studie av arbetsmiljö och enhetstider
Construction companies are frequently criticized for high prices and long construction time. At the same time, statistics shows that construction workers are on the sick-list for occupational injuries or casualties more than other groups at the labour market.Skanska built a block of flats with tenant-ownerships in Gävle. The construction consists of concrete walls with in-fill walls in the front. The purpose with this degree project is to perform a risk analysis in work environment with focus on repetitive strain injuries and control the time report for in-fill walls manufactured in a field factory. The result of this project will help to make more realistic cost predictions in the future.This degree project has been performed in cooperation with the construction company Skanska.
Prefabricerat trähusbyggande med moduler : För- och nackdelar samt förslag på vidareutveckling
The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..
Arbetsmiljöansvar på en gemensam arbetsplats : En studie över hur arbetsmiljön samordnas på en byggarbetsplats med flera entreprenörer
This essay describes coordination of the work environment on construction sites where many entrepreneurs share workplace. As employer, the entrepreneur has main responsibility for the workers safety on the construction site, the project supervisor is responsible for the work environment, and to coordinate the work environment a coordinator of the construction work environment is appointed. The purpose of this essay is to describe how the work environment is ensured on a shared workplace. In order to answer the essays questions I?ve used a juridical method to interpret the law.
Stress i byggbranschen : Orsak till stress i byggbranschen samt förslag på åtgärder
Stress and burnout are two words that are commonly occurring in many contexts today. More and more people experience that they are stressed and that they does not feel well. The long term sick -leave increases as a consequence of people being burned out. These phenomena prolong over all ages, sexes, classes and professional categories, which probably means that the construction industry would not be spared. In the construction industry, stress and bad health are no new phenomenon, already during the 1970s and big parts of the 1990 s, the construction sector were exposed to the phenomena.A sector that has a large turnover annually cannot presumably be faultless.
Att få tillträde till trädgården: Om konstruktionen av chefskap i coaching
During the last decade executive coaching has become an increasingly popular method of management development. Few studies have been conducted within this area, especially in Sweden, and little has been said about the construction of management in executive coaching. The purpose of this master?s thesis is to study executive coaching from a social constructionist perspective, focusing on the construction of management. The two research questions are: How is management constructed in executive coaching? How can we understand the construction of management in executive coaching? Additionally, we identify gender as a social construction of importance and thus include a gender perspective in our analysis.
Performativitet och bildkonst: eller hur apor verkar i världen
This essay examines the visual art of Helena Blomqvist with theory of performativity from Judith Butler among others, with a focus on the potential of visual art to question and dislocate norms. It consists of an analysis of three works of art from three aspects: the work of art, the viewer and the situation, and eventuates in an analysis of how the works relate to representation and norms. The construction of the works is related to Butler's theory of identity construction..
Byggnadsarbetarens syn på att bli involverad i projekteringen : En intervjustudie i byggprojekt
Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews. The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.
Konstruktion av efterbehandlare
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
Chefers identitet och identitetsskapande: en studie av chefer i offentlig verksamhet
The aim of this study was to gain a comprehension of managers experience of their identity and their construction of identity in the work sphere. 14 semi-structured interviews were performed with managers in the public sector. The interviews were analyzed from a hermeneutic approach. The results showed that the managers´ experience of their identity and their construction of identity were full of nuances and was characterized by a being and a becoming. The managers had several social identities at their disposal, which were brought to the fore due to the situation.
Förstudier av kommersiella fastigheter : En analys av arbetssätt ur ett projektledarperspektiv
This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit. The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes. The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process.
