Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping
This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.
Effektivisering av byggproduktion med VDC och förstärkt verklighet : Streamlining construction work with VDC and augmented reality
Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase.
Kartläggning av materialflödet i Peabs försörjningskedja till byggarbetsplats med SCOR
The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.

Byggnationsskillnader i Sverige, Finland och Tyskland
This paper is written as an examination paper at the University of Jönköping. The subject is chosen by Peab Sweden in Jönköping with whom further cooperation has been hold. The aim is to compare building methods and building materials in Sweden, Finland and Germany for further inspiration for Peab?s own market.BackgroundThe development of the construction industry develops new materials and methods to the market which has been forced by shorter construction times and the environment aspect. To pursue the development, further knowledge exchange should exist between the countries.
Tillämpning av GIS-analyser i MKB
The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.
Offentligt stöd till innovationer : Hur resonerar de offentliga stödgivarna?
The purpose with this essay is to study the public support givers view of the concept innovation and to study how the public support givers discuss and act around the division of public support to entrepreneurs innovations. The purpose is further to describe if the division of public support favour or not favour environmental innovations and to examine if the public support givers consider the industry for environmental innovations is profitable for the society?s economy.We have done several case studies where we have interviewed eight public support. Support givers in this essay are defined as public authorities and other organisations on local, national and/or international level that gives public support to innovations. The public support givers that take part of the essay is VINNOVA, ALMI Stockholm, Innovationsbron, Energimyndigheten, SU Holding AB, KTH Holding, Västra Götalandsregionen and MISTRA.Our theoretical starting point is Silverman and Baums theory ?Picking Winners or Building Them?.
Fick algblomningen i Östersjön 2005 några ekonomiska effekter? : Fallet turistnäringen på Gotland
Algal bloom is a naturally occurring phenomenon and occurs in all waters around the world but in recent years, algal bloom in the Baltic Sea has become more massive and more widely spread. When an algal bloom negative effects on the seawater quality, it may have an impact on tourism in the Baltic Sea. The aim of this thesis is to study, through a survey based on a production function approach, whether an environmental change as algal blooms, influenced the Gotland tourist accommodation industry and their "production of attractive overnight? in the summer of 2005. The results show that algal blooms did not have a great impact on companies ?production of attractive accommodations".
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
BIM-PROJEKTERING FÖRFÖRBÄTTRAD LOGISTIK
The construction industry depends on functioning logistics; if the logistics isn?tworking the construction site will risk to be interrupted due to material shortages orproblems with deliveries. Despite this, the construction industry is battling logisticproblems daily. This problem is very time consuming and costly for the companies.These theses are written for Peab Bostadsproduktion and investigate if it is possibleto focus on logistics earlier in the building planning process to reduce the problemsthat occur. Peab has partnerships with three companies that could be helpful for themin the work of reducing logistic problems.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Värdering av anbud vid kommunala upphandlingar av byggprojekt
The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice.
Kvalitetssäkring av hushållsnära avloppsfraktioner : vad kräver livsmedelsbranschen?
On-site sewage systems are common on the countryside of Sweden with approximately one million on-site systems installed. Due to insufficient function, these contribute significantly to the total discharge of phosphorus to rivers and lakes, causing eutrophication.
In order to reduce eutrophication and to fulfil one of the environmental quality objectives, the decision was taken by the Swedish Government in 2005 that 60 % of phosphorous in sewage sludge is to be recycled to arable land before 2015. To make recycling a reality, new solutions have to be found. Federation of Swedish Farmers (LRF) takes an active interest in this issue and has initiated this study.
One problem is that the food industry is sceptical towards recirculation due to the risks that products from sewage systems may contain pathogens, heavy metals and unwanted chemical compounds, e.g.
