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.

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..

Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall

Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.

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.

Investeringsmodell för lastpallstillverkning vid Södra timber i Långasjö : Investment model for pallet manufacturing at Södra timber in Långasjö

Huvudmålet med detta examensarbete var att undersöka om det för Södra timber är ekonomiskt hållbart att tillverka engångspallar till pelletsproduktionens tilltänkta säckningsanläggning i Långasjö, gentemot att köpa in engångspallar från en extern leverantör. Detta gäller då för 30 000 engångspallar om året.Intervjuer togs på Södra timber i Långasjö om vilket virke som var lämpligt från företagets sida att bli av med. Detta visade sig vara brädor av 19x75 mm och 75x75 mm. Dessutom beslutades i ett tidigt skede att en engångspall med måtten 1200x800 mm är en bra lösning då detta är europastandardens mått. Olika alternativ togs fram för hur man skulle kunna ta fram materialet och sänka produktionskostnaderna och avsåg då brädor 19x75 och klossvirke 75x75.

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.

Resultat från tre klonförsök med fågelbär, Prunus avium L, i södra Sverige :

This study was based on measurements of growth and shape of 50 clones of wild cherry, Prunus avium L, in south Sweden and aimed at finding out wether or not any of these clones are useful for commercial propagation. Initially, a short assembly of documented knowledge concerning wild cherry as a timber producing tree species was put together. The study of the 50 clones includes information gathered during the fall of 2006 from four trials located in the counties of Blekinge, Småland and Västergöland. The oldest trial, founded in Tranemåla, Blekinge, in 1992, was focused on offspring and aimed at discerning differences between provenances and at developing an adapted plant material. The other experiments were both clone trials and founded in 2002. These are based on 50 individuals selected from the offspring trial in Tranemåla.

Massivträ : Jämförelse mellan olika principer för sammanfogning av trä till plattelement med avseende på pris, hållfasthet och ekologi

Ökad användning av byggtekniken massivträ kan ge ett positivt bidrag till hållbart byggande. Utvecklingen inom datornavigerad bearbetning ger massivträ möjligheten att rationalisera byggproduktionen inom trä. Tekniken ligger rätt i tiden och kommer att värderas allt högre då den tillvaratar materialets karaktäristiska egenskaper.Utvecklingen av massivträ har resulterat i teknikvarianter av hur virke kan sammanfogas till solida element. Ett behov har funnits av en marknadsjämförelse mellan befintliga principer där studien förtydligar grundläggande skillnader för intresserade byggaktörer. Problemfrågan för denna studie har varit: vilka principer för sammanfogning av trä till plattelement inom massivträ är mest fördelaktiga? Detta sett utifrån faktorerna produktionskostnad, hållfasthet och ekologiska övervägningar.För att förtydliga den undersökta byggmetodens nytta i ett vidare perspektiv har det presenterats en allmän beskrivning av massivträ.

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..

Hallsta Pappersbruks virkesförsörjning

Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.

Älgexplosionen på 70- och 80-talet, ett hot mot sågverket?

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.
