  1. 1. Construction site productivity measurements : selection, application and evaluation of methods and measures

    Författare :Jan Jonsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : A construction company consists of a number of different sites where the physical production is taking place. This production is not always performed in the best possible way. There are numerous things such as organisation, logistics, co-ordination, technique, quality and others that can be improved. LÄS MER

  3. 2. Improved road design for future maintenance : analysis of road barrier repair costs

    Författare :Hawzheen Karim; Ulf Isacsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway maintenance; highway management; highway design; road planning; road design; highway engineering; road barrier; cable barrier; w-beam barrier; road barrier damages; barrier repair cost.; Building engineering; Byggnadsteknik; Vägprojektering för minskade drift- och underhållskostnader;

    Sammanfattning : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. LÄS MER

  4. 3. Managing Uncertainty in Environmental and Cost Life Cycle Studies of Building Design

    Författare :Peter Ylmen; Jesper Arfvidsson; Kristina Mjörnell; Johanna Berlin; Tomas Ekvall; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building design; life cycle; LCA; LCC; uncertainties; method; Building design; life cycle; LCA; LCC; uncertainties; method;

    Sammanfattning : In order to mitigate global warming and address other pertinent environmental issues, it is important to reduce the environmental impact from the building stock. Emissions can be large for both operational energy consumption and production of materials. LÄS MER

  5. 4. Working with the Fogbow : Design and Reconfiguration of services and Participation in E-Government

    Författare :Annelie Ekelin; Högskolan i Kalmar; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information Technology; e-government; e-democracy; Technoscience Studies; Informatics; 24-timmarsmyndigheten; serviceutveckling inom offentlig sektor; medborgarperspektiv; Informatik;

    Sammanfattning : This thesis is about the metaphors of the rainbow and the fogbow, investigations and evaluations, public Internet monitors, writing women, reflections and discussions about politics, design and democracy. It is also about the ongoing re-structuring of participation in service design within the development of E-Government. LÄS MER

  7. 5. Time dependent material properties of shotcrete for hard rock tunnelling

    Författare :Lars Elof Bryne; Anders Ansell; Wolfgang Kusterle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shotcrete; rock; granite; bond strength; compressive strength; pullout testing; failure modes; interfacial transition zone; micro structure; ettringite; set accelerator; shrinkage; drains; glass fibres; laboratory testing; tunnels tunnelling;

    Sammanfattning : In this thesis different mechanical properties for shotcrete (sprayed concrete) such as compression strength, bond strength, bending tensile strength, elastic modulus, free and restrained shrinkage as a function of its age was investigated. One of the main issues was to investigate the difference between ordinary cast concrete and shotcrete. LÄS MER
