<p>This project has been about investigation of the possibilities and design a proposition for a trainstation at Brände udde, Växjö. The station needs to be connected to Linné University and make thetransportation easier for students and personnel at Linné University and other universities andcolleges in Sweden. The plan should be a factor in the development of the university "campusvision" and result in an attractive building for the entire Växjö region at the same time as it has abeautiful and representing design and an exciting architecture.</p>

Purpose: It has been pointed out in studies how quality in the construction industry should be improved and how the building process has potential to be more efficient. The industry's project-based approach complicates the experience feedback and one is faced with new conditions before each project. When there is so much knowledge and experience in the industry, it should also be possible to make use of it and pass it on in the company. Can a perceived experience be fed back entirely or does knowledge get lost on the way? Today there is research on how knowledge management can improve the business but there is a lack of research on how to take advantage of knowledge gained during the warranty period. The aim of the report is to identify areas for improvement in the work with experience feedback. To find the most important improvement proposals for a construction company in the work experience feedback during the warranty period. Method: The report is a qualitative study and selected research methods are literature studies, case study, interviews, and document analysis. Findings: The study concludes that there are no procedures for documentation of the guarantee measures. For the most part construction services are used to fix errors. The result of that is that the person who carried out the error is not the one who solves it which risks that knowledge is lost during returning. Digital tools are used to advantage to document and collect experiences. There is an awareness in the investigated company that a database with more experience from projects is needed and interviews show that a need for it exists. The experience can be collected in the database so all of the employees use it. Meetings prove to be a good method for disseminating experiences. Implications: The report shows the conclusion that in the present situation there is no routine or system for experience feedback during the warranty period. The results show that all warranty measures should be documented. The experience that is assessed as significant can advantageously be taken up in meetings with the person who possesses the experience to be sure that no knowledge will be lost on the way. Small actions that are documented need not be brought up to the same extent, but the information can be used to detect recurrent errors. The report highlights the importance of experience being not only documented, it then becomes no experience feedback. The feedback itself is central to the benefit and improve the quality of the building. Digital tools can serve as important tools to document and gather experience and should be used on a larger scale. Limitations: The report is limited by the focus on the housing side in one construction company. The work doesn’t immerse in the economic factors or specific construction errors. The interviews are held only with officials and the majority of the interviewees work in the same district. Document analysis is used to observe the company's management, but an in-depth analysis of the system are not executed.

Title: Testing of mechanical expansion anchors and concrete screw anchors inhollow-core slabs For stabilization of prefabricated concrete elements during mounting obliquebraces are used. These oblique braces are occasionally attached into hollow-coreslabs. Abetong and Strängbetong are two companies using this method forstabilization and are in need of load values on what different fastenings canmanage attached into hollow-core slabs.Therefore this report is based on the testing of mechanical expansion anchors andconcrete screw anchors mounted in hollow-core slabs. The result of each fasteningis presented in tables with characteristic load values.After founding the concrete screw anchors most useful, an Excel-program wasdesigned where oblique loading can be presented.Keywords: Testing, mechanical expansion anchors, concrete screw anchors,hollow-core slabs, oblique loading, mechanical interlock, concrete fail, anchoragefail, concrete cone.

A lot of houses built during the Million Homes Programme are in need of major renovation. Today’s technology and materials are better than in the 60’s and 70’s. Both Swedish government and the European Union have set climate goals regarding energy consumption by 2020 and 2050. Achieving these goals would require better standards in buildings than the Building regulations demands, such as Umeå municipality’s construction requirements for new buildings. The report aims to investigate if a renovation of apartment buildings from the Million Homes Programme can reach Umeå municipality’s construction requirements. The goal is to create detail solutions which meet the energy demands. Three important components to reach the demands are U-values, thermal bridges and air tightness. Different constructions have been tested in these three areas by calculations with Isolerguiden Bygg 06, Isover Energi 3 and literature studies. The results of the calculations show that a lot of energy would be saved with a renovation of the building envelope, from 139 kWh/m2 to 42 kWh/m2. It’s possible to achieve sufficient U-values and reduce thermal bridges in all areas except the foundation. It should be possible to refurbish the foundation but it’s difficult to measure with the methods and tools available. With a major renovation it should be possible to make an old building as energy efficient and air tight as new constructions according to studies and experiments.

A fire that reaches the attic spaces in a multifamily building often comes with devastating consequences. Only 1 % of all attic fires have their starting point in the attic. The remaining 99 % begin in another fire cell, such as an apartment. A fire cell is a delimited part, such as ceilings, floors and walls, and each apartment in a multifamily building should form a separate fire cell. According to BBR (Boverket´s Building Regulations), attic spaces and ceiling voids, the attic should also form a separate fire cell with an area of maximum 400 m2 . The fire cell works as a shell to limit a fire and prevent proliferation. Besides fire cells, the choice of material has a significant impact on a fire and its spreading capacity to the attic spaces. A fire that starts for example in an apartment will emit hot gases and a common route for these gases is through the ventilation ducts. If there are any leaks in the ventilation ducts and visible materials, these hot gases might ignite surrounding insulation material. Insulation materials are divided into combustible and non-combustible materials. If a fire gets into contact with a combustible insulation material, this will be a contributing factor to its spreading to the attic spaces. Another way the fire can spread to the attic spaces is that the fire gets into contact with the eaves and then to the trusses. The purpose of this project is to examine the spreading of a fire to attic spaces in multifamily buildings. The goal of the project is to assist with proposing solutions that prevent the spreading of a fire to the attic spaces in a multifamily building. The project has been based on a literature study and interviews with people that work in the fields of fire- and construction technology and possesses high competence and together form a reliable source. The project´s conclusion shows that today’s standards and requirements in BBR are not always the cause for the fire to spread from a fire cell to the attic spaces in a multifamily building. Contributing causes for a fire that starts in another fire cell to spread to the attic spaces are leaks in the ventilation ducts, not appropriate choices of materials where ESP-insulations is a fire hazard and should be eliminated entirely as an insulation material, defective fire cellsboundaries, not prioritizing fire safety, lack of knowledge in case of an addition to the existing building, lack of knowledge in the construction-stage when it comes to the placement of iv openings from the ventilation ducts and absence of fire protection in the form of fire detectors, smoke detectors and other fire preventions solutions.

Skiftesverk 2.0 undersöker i vilken utsträckning en kontexts befintliga och historiska material, tekniker, former och strukturer kan användas i gestaltandet av ny bebyggelse. Detta för att hitta ett sätt att skapa ett mervärde i kontemporär arkitektur genom starkare kopplingar till en historisk kontext.Projektet beskriver ett sätt att utgå ifrån skiftesverk på Öland och sedan modernisera och omforma såväl själva byggtekniken som befintliga typologier. I presentationsmaterialet redovisas först teknikens bakgrund, historia och egenskaper tillsammans med material från fältstudier. Utifrån detta presenteras förslag på hur själva tekniken kan effektiviseras och industrialiseras. Sedan följer gestaltningar av en moderniserad version av skiftesverk i såväl teknik som traditionell form och byggstruktur.Projektet är tänkt att belysa ett sätt att förhålla sig till hållbar arkitektur i termer såsom inte bara ekonomiska utan även ekologiska och kanske även sociala aspekter. / SKIFTESVERK 2.0 (POST-PLANK 2.0) examines the extent to which the context of existing and historical materials, techniques, forms and structures can be used in the shaping of new settlements. This is to find a way to add value in contemporary architecture through stronger links to a historical context.This project describes a way to first look at post-plank on Öland and then modernize and reshape both the actual construction technique that existing typologies. The presentation material starts with describing the background of the technology with its history and characteristics along with material from field studies. Based on this, a proposal is presented showing how the technology itself can be streamlined and industrialized. Then follows a design of a modernized version of post-plank in both technology and traditional shape and construction structure.The project is meant to illustrate a way of relating to sustainable architecture in such terms as not only economic but also ecological and perhaps even social aspects.

Byggbranschen är en olycksdrabbad bransch där många allvarliga olyckor inträffar. Skanska Sverige AB arbetar hårt med att minska antalet olyckor och säkerhetsarbete är något de prioriterar högt. Denna rapport har genomförts på uppdrag av Skanska Värmland. Syftet var att ge förslag på hur arbetsmiljön och säkerheten kan förbättras inom Skanska genom att belysa var problemen finns och vad man kan göra utöver det man redan gör idag för att komma vidare med utvecklingen. Underlag till rapporten är en teoristudie om hur Skanska arbetar med säkerhet idag och vilka lagar och regler som finns. Det är även en intervjustudie, där säkerhet och säkerhetsarbete diskuterats med anställda på olika positioner inom Skanska och Arbetsmiljöverket. Rapporten belyser de problem som finns gällande beteende och attityder inom byggbranschen, och konsekvenserna av dessa. Mycket har gjorts gällande lagar, regler och rutiner som rör säkerhetsarbete och det är nu en beteendeförändring som måste till för att kunna fortsätta att minska antalet olyckor. Idag läggs visst fokus på att försöka förändra dessa beteenden på individnivå för att åstadkomma ett bättre säkerhetsklimat. Forskning tyder dock på att det kan vara effektivare att försöka förändra säkerhetsklimatet från andra hållet, genom att arbeta med ledningens signaler och gruppens värderingar. I en väl fungerande organisation där ledaren sänder tydliga signaler om prioritering på säkerhet uppfattar gruppen vikten av säkerhetsarbete som tydligt och ett bättre säkerhetsklimat uppstår. Detta påverkar i sin tur individens beteende och leder till en högre säkerhet. Viktiga faktorer för ett bra säkerhetsklimat inom en grupp eller organisation är;  Ett starkt ledarskap som tydligt prioriterar säkerhet.  En fungerande organisation där rutiner och planering fungerar.  Att en riskuppfattning finns och att risker inte accepteras.  Att en prioritering på säkerhet kontra produktionsresultat är tydlig.  En kompetens hos alla inblandade.  En positiv attityd till säkerhetsarbete.

Det här arbetet handlar om att hitta nya möjligheter för en framtida byggnation i Arvika hamn. Att ta vara på det som finns idag och komplettera miljön med fungerande infrastruktur och strategiskt planerade byggnader för en hållbar stadsutveckling. Hamnen i Arvika, som för en tid sedan var ett verksamhetsområde, står med stora öppna ytor och Arvika behöver en ny stadsdel som kan locka människor genom nya aktiviteter, verksamheter och bostäder. Bakgrunden till arbetet och varför området idag står tomt är på grund av gifter i marken av tidigare verksamheter och översvämningsproblematiken som inte fått en lösning fram till nu. En förstudie med ingående analyser och ställningstaganden har varit grunden för hamnens utformning. I arbetet så har hänsyn tagits till vad Arvikas invånare tycker om hamnen och vad de vill se när ett nytt hamnområde byggs. De största utmaningarna har varit att skapa nya anknytningar mellan hamnen och centrum för att hamnen ska bli en del av stadskärnan. Att få plats med visst många bostäder på en begränsad yta och samtidigt skapa smarta lösningar för det offentliga rummet för att nå en social hållbarhet. Arbetet har lett till 250 nya tillgänglighetsanpassade bostäder som är byggda på miljöklassade material enligt Sundahus.se och klarar av arbetets krav att nå miljöbyggnad guld enligt SGBC! De nya vägarna och gångstråken har löst problemen med järnvägen och gör så att gående och bilister slipper ta sig över järnvägen. Det öppna rummet och de nya verksamheterna i området kommer att få fler personer att vilja vistas i det nya området och har en attraktiv miljö som även kommer locka turister till Sveriges innersta hamn! / This job is about finding new opportunities for a future construction work in Arvika harbor. To make the most of whats available today and complement the environment with functioning infrastructure and strategically planned buildings for sustainable urban development. The harbor in Arvika, what used to be an industrial area, stands with large open spaces and Arvika need a new district that can attract people with new activities, businesses and homes. The background to this work and why the area today stands empty is because of toxins in the soil by past activities and flooding problems which have not been resolved until now. A feasibility study with detailed analyzes and statements has been the basis for the harbor's design. The work has been taken into account what Arvika citizens think about the harbor and what they want to see when a new harbor area is being built. The biggest challenges has been to create new connections between the harbor and the center of the city so the harbor can become a part of the city center. To make room for a specific amount of homes in a limited amount of area and to create smart solutions for the public space to reach a social sustainability. The work has led to 250 new accessibility custom homes that are built on environmentally certified materials and are capable of the works requirements to reach miljöbyggnad guld according to SGBC! The new roads and walkways have solved the problems with the railway so that pedestrians and motorists will not have to cross the railway. The open spaces and the new activities in the area will get more people to want to visit the new area and has an attractive environment that will also attract tourists to Sweden's innermost harbor!

The work aims to investigate how site managers are planning projects, and how this is experienced by the craftsmen regarding work environment with a psychosocial and physical aspect and construction management. Recommendations are made to improve construction management based on the results from the interviews. The work is being carried out as there is a greater focus on work environment in the workplaces today. A way to facilitate the additional administrative work that arises with this focus is to improve production planning. Placing a greater focus and more time before production has started can be beneficial to the construction project. In the report ten interviews are made from five different projects where we interview a site manager and a craftsman on each project. Among the site managers, many felt that there was a high workload due to lack of resources or additional work. All interviewees agree unanimously that one should have a craftsman or safety representative at an earlier stage during the production planning. Several site managers are requesting a clearer structure in the organization at an earlier stage in production planning. Craftsmen request official meetings with a clearer structure on the information provided.
