Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and Renovation ofold buildings.

It is sixty years since Sweden's first star-shaped housing estate was built in Gröndal, a suburb of Stockholm. Olle Engkvist, the building contractor, was the driving force behind the residential area and it was designed by architects Sven Backström and Leif Reinius. The estate comprises detached star-shaped houses suited to a more hilly terrain and terraced star-shaped houses on the flat land. The eight gardens of the terraced houses form the shape of a hexagon. It is these gardens, designed by Sven Hermelin and Per Friberg, which are the main focus of this thesis. The buildings on the estate have recently been renovated and it is now time for the gardens to be restored.

This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary Renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.

The project description is to draw an extension or annex to the existing Nationalmuseum building from 1866.The annex is designed to complement Nationalmusems activities and contain internal and public functions. Artentering the building must not be crossed by public visitors. Art and staff must be able to seamlessly move betweenthe extension and the main building. The new building includes a public study room for scholars working withthe collection of art on paper, workshops, conservation studios, art spaces and warehouses. Additionally, theannex is designed to host a large number of office spaces.With the Renovation of Nationalmuseum they intend to open up the today built in south atrium.

HSB Göteborg owns and manages the property Masthugget 11:13 also called the Corvette in Gothenburg. The Corvette contains mostly office space but also shops, homes and garages. HSB Göteborg utilizes approximately 5000 square meters to its headquarters but in December 2014 they will move operations to Johanneberg Science Park. The risk of an increased proportion of vacancies in combination with relatively low rents and other tenant terminations allows HSB to ask for a future plan for how the real estate should be developed in order to remain profitable.Through studies of the area, urban office prospects, property current status and legal and economic conditions have different potential types of businesses been evaluated. City Planning Office program proposal forms the basis for the analysis of future plans for the area.

En av de större utmaningarna med ombyggnadsprojekt är de fall när det i byggnaden finns kvarboende eller andra brukare under tiden. En ombyggnad innehåller i regel både bygg- och rivningsarbeten som ofta medför störningar för människor som vistas i eller intill fastigheten. Samtliga störningar är påverkningsbara och kan vid god projektering och produktion minskas.Målet med examensarbetet har varit att ge konkreta förslag på hur ett fastighetsbolag kan arbeta för att öka hyresgästens kvalitetsupplevelse under en ombyggnad som sker i eller intill hyresgästens lokal. Detta har gjorts genom att identifiera vanliga störningar, genom att påvisa hur hyresgästen har påverkats av dessa störningar och genom att undersöka hur tidigare uppkomna störningar har hanterats.I samråd med fastighetsbolaget Vasakronan har tre ombyggnadsprojekt valts. På respektive ombyggnadsprojekt har kontorshyresgäster, intern projektledare och extern projektledare intervjuats.  Även observationer i form av platsbesök och litteraturstudier har genomförts.Studien har resulterat i förbättringsförslag till fastighetsbolaget.

 AbstractThe background for this study is that there were a great amount of buildings constructed in Sweden in the years 1965-1975 in a program designed to create one million apartments in a time-period of ten years. These buildings are now, somewhat forty years later in most cases in very poor condition and the need for Renovation is great and urgent. This has become a growing problem and more and more voices are being heard pointing towards the vast and extremely expensive task of renovating these buildings. Lately, it has also been more and more important for buildings to be energy-efficient and sustainable environment friendly.In recent years there has been an atempt to solve these problems by renovating such buildings but at the same time making them very energy-efficient. This is in some cases being done by isolating the shell of the building and changing the ventilation-system and so forth.

In the current situation a big part ofthe settlements that exist in Sweden isin need of Renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.

The knowledge of value-enhancing factors in condominiums is very important for real estate agents when valuing condominiums, but it is also of interest to the owner for an upcoming Renovation and sale. Previous research has sorted out the most fundamental factors affecting value of condominiums such as location size, age and condition.The purpose of this paper is by consumer?s actual preferences regarding various attributes identify the most value-adding factors in condominiums. Thereby we want to add and nuance previous research.This has been done through a quantitative method in which possible buyers have ranked how various attributes affect their willingness to pay. The results were analyzed and the median of the various attributes have been recognized.The result shows in accordance with previous research that the location is the primary value-adding factor.

Detta examensarbete har utförts i samarbete Statens Fastighetsverk. I dagsläget pågår renoveringen av Nationalmuseum där byggnaden skall återställas till sitt ursprung och ett nytt ventilationssystem skall tillgodose ett stabilt inneklimat för bevarandet av museiföremålen. Examensarbetet undersöker hur de krav som ställs på ventilationssystemet kan kombineras med de begränsningar som byggnadens kulturminnesmärkning medför genom att besvara frågan ?Hur kombinerar man dagens behov av installationer med en kulturhistorisk byggnad utan att påverka det kulturhistoriska värdet?? För att exemplifiera denna problematik presenterar vi ett principiellt lösningsförslag för installationssamordningen till en utvald del av byggnaden.Ventilationsförsörjningen till utställningssalarna på Plan 4 utgör ett av de svåraste samordningsområdena i byggnaden. Det valda utrymmet för lösningsförslaget är bjälklaget på Plan 6 som skall försörja en av dessa salar.

Those companies whichcan utilize previous experiences are positioned with a significant competitive advantage. ToABB Robotics it has become evident that the knowledge transfer process within the productdevelopment department is inadequate. This study was a result and an attempt to address thisunsatisfactory insight.

När det handlar om ROT-projekt (renovering, om- och tillbyggnad) är det viktigt för entreprenören att uppnå långsiktig lönsamhet. För att säkerhetsställa detta är det av stor vikt att upprätta noggranna kalkyler som håller under hela byggprojektet. I dagsläget finns små marginaler för eventuella kostnadsökningar därmed ytterst lite utrymme för misstag. Eftersom förutsättningarna vid ROT-projekt ständigt varierar beroende på typ av badrum och skadeorsak är det därför väldigt svårt att uppskatta och beräkna kostnader utifrån rådande förutsättningar. Utifrån detta finns det ett behov hos entreprenören att förstå varför kalkylerna avviker och hur man kan undvika detta i framtida projekt.Examensarbetet innehåller både en analys av kalkylerade kostnader och dess verkliga utfall samt en analys av kalkylverktyget Meps.Då ROT-sektorn är stor och omfattande har vi valt att avgränsa oss till badrumsrenoveringar som en följd utav vattenskador.Utifrån analys av kalkyler och kalkylverktyget samt intervjuer med parter både från entreprenör och från beställarsidan har vi kommit fram till en rad slutsatser om hur företaget kan ta fram noggrannare kalkyler i framtiden.Framförallt anser vi att företaget ska föra en tätare dialog med försäkringsbolagen för att vara en del i utvecklingen av kalkylverktyget. Vi anser även att man bör avsätta resurser för att utveckla erfarenhetsåterföringen inom företaget..

The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of Renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.
