Prefabricerade väggelement av hampabetong
Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.
Kommunikationseffektivitet och kommunikationsstrategier för L1- och L2-talare i referentiella problemlösningsuppgifter
This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.
Utvärdering av Revit Architecture : Med hänsyn till Autocad Architecture
This Degree project summarizes how it is to work in the CAD program Revit Architecture. This was done because AQ Arkitekter in Eskilstuna is interested in how Revit works. Especially compared to AutoCad which is the software they are using today. Will their work become more efficient with the new software?The starting point was to find out how it is to work with Revit when you only used AutoCAD Architecture before.
Intäktsredovisning i svenska byggföretag -En studie kring IFRIC 15 och IASB:s föreslagna standard och dess påverkan på intäktsredovisningen i tre svenska byggföretag
One of the most crucial entries in the financial statements is revenue. Despite the importanceof revenue a lot of mistakes are made concerning this entry because of the extensive room forjudgements. Especially in the construction companies where a lot of differences exist due tothe fact that different standards are used for similar business transactions.The research concerning IFRIC 15 and the new upcoming standard for revenue recognition isnot very extensive. Studies including both IFRIC 15 and the new standard are even morelimited. Therefore this study aims to compare the effects of IFRIC 15 and the new upcomingstandard for revenue recognition, Revenue from Contracts with Customers, in three Swedishconstruction companies.
Stenebergs sockerbruk: en fallstudie av en timmerstomme fr?n 1739
Stenebergs sockerbruk is a large log-timber construction, purpose built as a sugar refinery in
1739 and is one of Sweden's oldest industrial buildings constructed entirely out of wood.
Despite receiving the status of a listed building (in Swedish: Byggnadsminne) in 1977, there
exists today a surprisingly low amount of documentation of the building itself. In order to
enhance the existing and lacking building documentation, this case study aims to shed light
on the building's log-timber built frame, focusing on how it was constructed, how the long
lengths of its walls were handled and what type of joinery and tools were used.
A thorough investigation of the building is conducted on site, followed by gathering of
information which is then presented through text and illustrations. The findings indicate the
orientation of timbers, location of joints and scarfs as well as tool marks which together
contribute to the forming of a basis of understanding of the building's construction..

Tillämpning av Lean Construction - Sunnanå hamn
This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.
Vattendragsrestaurering i teorin och fiskinventering i praktiken : en litteratur respektive metodstudie
Running water-pathways have played an important roll in Sweden and frequently been
manipulated. One profound change was made during the period of logging when
streams were cleared from obstacles as big boulders, sharp bends and side-streams.
Dams and different constructions gave control of the stream water and the streams
became channel-like with a homogen structure. This interference gave problems for
many fish populations and resulted in a shortage of feeding habitat, over-wintering
habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural
temperature fluctuations. Many of these historical changes of the watersheds are now
subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.
Östra Kvillebäcken En gröna stadsdelen? En fallstudie över Östra Kvillebäcken i Göteborg
The study is a case study about the green urban district, East Kvillebäcken, located in Gothenburg, Hisingen. East Kvillebäcken is the first urban district in Sweden with ambition to build sustainable according to the certification system Miljöbyggnad, which make it a pioneer project. The purpose is to investigate the upcoming and the meaning of the green urban district in East Kvillebäcken and show how public employees think the urban district can affect social, ecologic and economic aspects in the area. Dialogue interviews were done with four public employees, one estate agent and two residents. Local plans and other authority documents were used to get a deeper understanding for the case study.
Livscykelanalys för koldioxidutsläpp från flerbostadshus
Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
Sverige till Indien - En interkulturell förhandlingsresa
The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

BIM förändrar produktionen
Because society?s demand for quality, efficiency at low cost is constantly increasing, companies are increasingly choosing to invest new methods to achieve these points. Those who manage to find ways to improve their processes are often the companies that have the greatest chance of becoming a winning player in the market. BIM is a new method that can reduce the internal costs while increasing communications between different parties. However there is disagreement about what BIM is and its purpose.
Gräfsnäs dolda skatter
This paper examines how to use different kinds of source material for building surveys. The studyexamines how to use legends, construction archaeological surveys and Ground Penetrating Radar(GPR) as source material, and use them against each other to ensure the reliability they have.As a starting point I used Gräfsnäs castle ruin in Alingsås, Sweden, as an example. Gräfsnäs castlewas probably built in the Middle Ages and was rebuilt through the ages until it became a ruin in thelate 1800s. The castle ruin is today Alingsås most visited attraction.The investigation has focused on three areas which are located in the very ruin; rescue tunnels, thecellar vault and the treasure.There are legends that describe how the castle lord of Gräfsnäs fled an attack of the Danes in 1612 ina rescue tunnel which ended at the beach. At the construction archaeological surveys carried out in1935-36 they found a sewer in the courtyard that was once served as rescue tunnel and ended in themoat.
Modus vivendi. : Om könsidentitetens motstånd och beständighet i kvinnodominerade yrken.
The aim for this study was to find out what strategies women use to not react against inequality and sexist prejudice. In the study I used a critical realistic approach through, primary, the social ontology presented by Margaret S. Archer. The study focus on both the women?s construction of femininity and their construction of masculinity and what directions it constitutes for the women?s social orientation.
