Genomarbetade förfrågningsunderlag medför tids- och kostnadsbesparingar : En studie över handlingars påverkan i byggskedet
In order for construction projects to be completed within the specified time limit while at the same time be financially sustainable it requires thorough preparation and an extensive planning. Most essential is the groundwork and the design that determines the project's progress. There are many aspects to consider in order to avoid inconveniences such as delay, litigation, unexpected cost etcetera. If mistakes are made in an early stage it is very likely that the error will follow the process and become an expensive correction cost towards the later part of the project. In other words, it is expensive to rectify defects later on.
Functional Cuts
Our everyday life is becoming more active and the activities we perform influence the way we dress. Due to an increase in activities undertaken in an urban environment, demands are changing and the need for active wear that meets the new demands follow suit. The four characters represented in the research can be seen as a reflection of the functional features needed, including base layer, mid layer/insulation and shell.Despite the increase in activities, most of our clothes are still constructed on static dummies or drafted on a table in 2D and the main developments within the active sportswear field is driven by material innovation. By creating garments on a body in movement, my aim is to develop new functions and expression in active sportswear through construction.Construction methods in active sportswear are examined and understood through observations and reconstructions and constitute the foundation of a study of movement for a design recovery.The movement and features required for leading an active urban life sets the direction of the development of new func- tional garments. A series of trial and error sessions and draping fabric on a live model in movement created the prototypes used in functionality tests to establish their feasibility.
High Orbit Ion Cannon : Går det att skydda sig?
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.
Bygg- och rivningsavfall utifrån ett miljöperspektiv : Med fokus på EU:s avfallsmål och en hållbar avfallshantering
The purpose of this report was to identify the current waste management of non-hazardous construction and demolition waste in a few Swedish construction companies, based on the different steps in the waste hierarchy with a focus on waste prevention, reuse and recycle. Additionally, the purpose was to attempt identifying opportunities, obstacles and as well as to propose possible solutions from an environmental perspective. The method used was a qualitative study using interviews conducted through emails and phone with employees occupying positions that could answer this reports questions. The results of this report indicates that waste management of construction and demolition waste has improved, and less waste goes into landfills. The concern is that the overall amount of waste being produced is not decreasing, thus calling for actions preventing the production of waste.
Identifiering av avgo?rande faktorer fo?r optimal intern bygglogistik : En fallstudie av tre byggarbetsplatser
Unlike the manufacturing industry, the construction industry is always in motion. Each new construction project brings new opportunities, and it requires a new plan, new organisation, and new suppliers. All construction projects are very different from each other and in terms of a logistical perspective, this is very weak as it makes it difficult to get a flow in the production and to make flawless routines. The way the external and internal logistics are managed, can effect the final product in the time taken to produce it, the quality of the product and the profit made from it. When internal logistics are handled poorly, it could result in materials not being at the right place at the right time, or information not going through to the right person.
Industrialiserat byggande
The industrialization of construction is increasing in Sweden which leads to higher demands of prefabricated components and cells. But what does the business of construction think of the industrialized business and what can be done in order to decrease faults and errors with these products? Today we have many manufacturers who have different technical solutions which might lead to difficulties when assembling components and cells at the building site. But by trying to make a more opened market, with possibly standardized connections details and improving the communication between the different participants, the prefabricated components and cells can be made and assembled with less errors. This is something that needs to be done in order to establish a more secure business, and especially when working with new companies and methods, when using industrialized products..
Traditionella och samtida bottenbj?lklag: med fokus p? isoleringsmaterialen
The survey aims to shed light on traditional and contemporary bottom floor frames, their construction
and different insulating materials; mineral wool, wood shavings and charcoal. The purpose is to
analyze and discuss the similarities and differences as well as the pros and cons with a focus on the
construction and the different insulating materials.
The work has been limited to comparing two different wooden floor frames. The first one is based on
a real floor frame from an older building, this example is presented as the traditional floor frame in
this study and are from around 1940. The other floor frame is presented as a contemporary floor frame
and is based on wood building type descriptions and literature.
Bakhjulsupphängning, fyrhjuling
Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.
Betongarbeten under vintertid : Fokusering på platsgjuten betong
This report is on concrete work during the winter and is implemented on Peab?s behalf. The assignment was to describe the differences between a summer- and a winter casting. While it shows the complications that exists, it also show what aids are available, both electronic via computer and physical aids.The information that I have developed is originally from theory in books, information on the internet as well as practical experience from knowledgeable people that works in construction output. Other theories are those I have learned throughout the education to become a construction engineer, including all oral sources over the years.The results I have come up with, I hope will be able to help future construction projects in the planning phase of a winter casting.
Att konstruera en gemenskap -teori och konstruktion av virtuella samhällen
Virtual communities are a phenomenon that is becoming more
common as the information technology comes with in reach for
the general public. This report will bring the theories and
construction of a virtual community together.
The purpose of this report is to describe the different theories that have
emerged from the research within this field and to examine the work procedures
that have been used during the development of a site for a MDA-community. The
MDA-website is a homepage on the Internet that was developed to bring the
students closer together. The report describes the work of the project group,
why the website was not completed and at the end the theories are looked at on
the basis of the construction of the website..
Fjortisgrubbel och tonårskärlek : ? en genusstudie av två svenska ungdomsfilmer gjorda med 35 års mellanrum
AbstractHeadline: Young trouble and teenage love (Fjortisgrubbel och tonårskärlek)Number of pages: 37Author: Annika IlmoniTutor: Amelie HössjerCourse: Media and communication CPeriod: Autumn 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim: The purpose of the work was to produce a comparing study of two Swedish teenage films from different periods of time, 1970 and 2005. An analysis was to be made of how love between teenagers as well as the heterosexual relationship in general was depicted in each of the films and further investigate the gender construction in both films.Material/method: With the intention of narrowing down the complexity and make the evaluation more lucid 5 scenes from each film were used for comparison, these were chosen through the Anglo Saxon dramaturgy. To make the scenes more comparable 4 factors were used for analysis in each scene, these were: clothes, recreational activities, behaviour and environment. Beside the above given factors the heterosexual relationship were analysed and compared in each of the scenes through the theory of dominance in dialogue.Main results: The gender construction occurs obliviously in the older film from 1970 while taking place in a more conscious way in the film from 2005. Further on the heterosexual relationship is perpetually depicted in the 70?s film with a submissive girl and predominant boy, the same dominance is easily seen in the more recent film but with a higher rate of equality as the girl is portrayed as the dominant character in almost half of all scenes.
Morgondagens arbetsledare
There is a lot going on in the construction business right now. It feels like everywhere you turn there is a building sight. Furthermore the business is heading a generation change and the need of recruiting new construction engineers is huge. How is the business going to handle the transition that they are facing? The question has been in progress for at while and I wanted to find out what the current students feel about taking the step into the working life and replace the veterans.A research is made about student?s opinion about their education and future work life.
Konceptbyggande med standardelement
Syftet med examensarbetet är att hjälpa ett företag med att införa standardlittera för deras prefabricerade betongelement som ingår i deras Konceptet. Införandet av standardlittera ska resultera till att återfinna och gruppera deras betongelement i CAD-systemen. We did our thesis project at one of the most prestigious Swedish construction companies. We have examined the possibilities of doing sandwich elements to standard elements which would increase the degree of industrialization. The company has developed a concept that is based on a more refined process of industrialization.

En villaleverantörs möjlighet till etablering i Finland : analys av för- och nackdelar
The construction market has, as a result of the crisis in Europe been uncertain in recent years. During the year 2013, the construction will be stabilized, in particular Finland. The geographical proximity between Sweden and Finland and similarities in cultures and climates makes Finland a coveted market for many Swedish companies.Differences in national regulations and guidelines, which are produced by the authorities in different countries, are examples of barriers that may hamper the process, including for Swedish villa suppliers, to establish themselves on the Finnish market. It may be useful when facing a new export drive, to look up what similarities and differences there are between the countries building codes, to prevent mistakes and unnecessary costs to the project work..
