The purpose of this Master Thesis is to study how the value stream mapping concept can be applied along the construction supply chain for prefabricated massive timber floor elements. Identification and qualification of waste are starting points to propose suggestions on how to reduce and/or eliminate them. In order to use the value stream mapping along the construction supply chain, pertinent data has been collected and analyzed. To conduct the value stream mapping, the first three steps of the lean thinking principles in construction have been followed. The first step aims at defining the customer and his value as well as the value for the delivery team and how it is specified in the product. The second step is based on identifying the value stream and this is done through defining the resources and activities needed to manufacture, deliver and install the floor elements. This is conducted by using the VSMM methodology. In addition the current practice should be standardized and key component suppliers should be defined and located. The third and last step identifies non-value adding activities, in other words waste and suggestions on how to remove and/or reduce waste have been reached. Wastes from product defects, transportation waste and waste of waiting were to be found in the construction supply chain. Propositions to reduce and/or eliminate wastes were to implement a more careful planning of the manufacturing process and production schedule, to apply lean production principles in the manufacturing facility and decrease and or eliminate storage time. The study made has shown that in the supply chain of massive timber floor elements at Limnologen there is a big potential to lower costs and increase customer value as value added-time accounted for only 2% of the total time.

Ett sekellångt förbud mot att bygga hus med trästomme högre än två våningar har gjort att värdefulla kunskaper om träbyggandet gått förlorat samtidigt som andra material istället etablerat sig på marknaden.För utvecklingen av flervåningshus i trä har Växjö blivit en förebild för andra städer i Sverige och resten av världen. Med denna studie vill författarna skapa en uppfattning om var i utvecklingen vi står idag samt tillvarata erfarenheter från fyra representativa projekt.Målet har varit att ta fram faktorer i produktionsprocessen som påverkar tid, kvalitet och ekonomi för flervåningshus i trä. Dessutom har det undersökts i vilken grad och på vilket sätt erfarenheter från tidigare projekt omsatts i senare projekt.Arbetet resulterar i ett antal punkter som är viktiga att ta ställning till vid en byggnation av flervåningshus med en träbaserad stomme. Dessa punkter berör bl a vad som behöver beaktas vid hög prefabriceringsgrad, varför och hur väderskydd bör användas samt hur sättningar påverkar en träbyggnad. Utvecklingen är starkt beroende av kontinuitet och av att fler hus av denna sort byggs. Detta skapar förutsättningar för att det skall gå snabbare och bli mindre kostsamt att bygga med trä.

The thesis deals with a proposed layout of a multi-storey apartment building on the territory of the town of České Budějovice. The thesis contains a literary overview to inform the reader about the issues of design documents, analysis of the land use plan for the corporate town of České Budějovice in connection with the building location and, last but not least, related design documents in agreement with the applicable decree. The objective of this thesis was to develop the design documents meeting the low energy consumption standard, i.e. meeting all current requirements for modern and energy-saving construction projects, in terms of the appearance, employed technologies and materials. An integral part of the results is a placement of the project in a suitable location, as outlined by the land use plan. The thesis is concluded with an evaluation of the architectural and structural solution and of the selected materials in respect to the low energy consumption standard of the building.

Purpose: The aim of this study is to provide improvement suggestions on how the amount of carbon dioxide emissions can be reduced in the construction of mainly multi-storey timber buildings. Proposals are made after identifying where in the life cycle the largest emissions occur. Method: To achieve the goal of this study a case study was performed on an existing multi-storey timber building. A life cycle analysis (LCA) was performed to identify where in the life cycle the biggest emissions occur. To gather all important information about the project, document analysis was conducted. In addition, a literature study was made on the subject which supports and enhances conducted study. Findings: From literature study, case study and document analysis results have been listed which forms the foundation for the following suggestions of improvement. The life cycle analysis has identified that the largest amount of carbon dioxide is 28 % and is obtained in sawmills. The production of glue produces 25 % and transports during the lifecycle produces nearly 20 %. Implications: The conclusion contributes to reducing the amount of carbon dioxide emissions in future production of mainly wooden buildings. The greatest amount of carbon dioxide have been identified and the following proposals have been made to reduce emissions. Make sawmills more effective to reduce emissions. Produce and use environmentally friendly adhesive with similar characteristics. Use waste from forest felling, sawmills and glulam factories for production of biofuel used for transports. Limitations: This study has only covered multi-storey buildings in different wooden systems, the problem is probably also relevant for other buildings. Keywords: Carbon dioxide emissions, LCA, multi-storey building, timber and wooden frame. / Syfte: Syftet med denna studie är att ge förbättringsförslag om hur mängden koldioxidutsläpp kan minskas vid byggande av främst flervåningshus i trä. Förslag tas fram efter att ha identifierat var i livscykeln de största utsläppen sker. Metod: Syftet med arbetet uppnås framförallt med en fallstudie utförd på ett existerande flervåningshus med stomme i limträ. En livscykelanalys (LCA) utfördes för att ta fram var i livscykeln de största utsläppen sker. För att samla in all viktig information om projektet utfördes även dokumentanalys. Fortsättningsvis utfördes en noggrann litteraturstudie inom ämnet som stödjer och förstärker utförd studie. Resultat: Från litteraturstudie, fallstudie och dokumentanalys har resultat tagits fram som ligger till grund för framförda förbättringsförslag. Livscykelanalysen har identifierat att den största mängden koldioxidutsläpp är 28 % och avges från sågverken. Framställandet av lim avger 25 % och transporterna under livscykeln avger ungefär 20 %. Konsekvenser: Slutsatsen bidrar till att mängden koldioxidutsläpp kan minskas i framtida produktion av framförallt byggnader i trä. Där koldioxidutsläppen är som störst i livscykeln har följande förbättringsförslag tagits fram för att minska utsläppen. Effektivisera sågverk för att minska utsläppen. Framställa och använda ett miljövänligare lim med liknande egenskaper. Utnyttja spill från skogsavverkning, sågverk och limträfabrik till att producera biobränsle som kan användas till transporter. Begränsningar: Arbetet har endast behandlat flervåningshus i olika stomsystem av trä, troligtvis är problemet aktuellt även för andra byggnader. Nyckelord: Flervåningshus, koldioxidutsläpp, LCA, limträ och trästomme.
