    Arbetsmiljöorganisation i byggbranschen2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Ser man på ett tio års perspektiv, så har det i genomsnitt en person i månaden dött på den svenska byggbranschen. Många av dödsfallen beror på organisatoriska brister, det kan exempelvis vara att man gjort otillräcklig undersökning av arbetstagarens erfarenhet eller bristfälliga skyddsronder. I en studie uppskattades det att ungefär 60 % av Europas olyckor inom byggbranschen var direkt eller indirekt på grund av organisatoriska orsaker.

    I mitt projekt vill jag analysera hur ett byggföretag hanterar sin arbetsmiljöorganisation. Projektet är en fallstudie av hur företaget hanterade arbetsmiljöorganisationen i ett av byggprojekten. Vilket har genomförts av byggföretaget MTA Bygg och Anläggning. I projektet har jag begränsat arbetsmiljöorganisationen till roller inom arbetsmiljöorganisationen, förberedelser för arbetsmiljövänligt arbete samt systematiskt arbetsmiljöarbete.

    Genom litteraturstudier, internetstudier och kvalitativa intervjuer har jag undersökt vilka faktorer som ger en bra arbetsmiljöorganisation. Jag genomförde intervjuer med inom arbetsmiljöorganisation samt studerade dokument för arbetsmiljön hos företaget för att kunna analysera byggprojektet. Jag ville ta reda på hur företaget kunde förbättra sig och vad man skulle kunna lära av byggföretaget.

    Modeller för hållbar utveckling: - en analys av tillämplighet av befintliga modeller vid upprustning av Miljonprogram2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Areas within the so-called ”Miljonprogrammet” (Million programme) are in a desperate need of renovation. The areas comprises of 25 percent of the total housing stock in Sweden. The increased environmental awareness from both the general public and the decision makers has resulted in a variety of technological solutions but the problems are often wider then that and includes both social- economical- and ecological factors. To solve the problems and to renovate the areas in a sustainable way there are a need for holistic models for strategic planning. The engineering consulting firm SWECO has developed such model for sustainable development in developing countries. Can this model be a possible approach to the current situation?

    The concept “Sustainable City” was developed by SWECO on behalf of the Swedish government and the organisation SIDA to be presented at UN’s top meeting for sustainable development in Johannesburg 2002. The concept is based on three parts: Working method, Subsystems and Institutional factors. The model is based on a multidisciplinary approach to try to find synergies between the different solutions in the process. This report focuses on the first part, the working method, since the other parts of the concept doesn’t really apply to Swedish conditions.

    A thorough literature study within the range of sustainable development was conducted to build a theoretical understanding of the term Sustainable Development. The concept “Sustainable City” was analysed, a minor case study was also conducted to get a more detailed view of the real world of renovation.

    The Analyse and Result points to that the model may not be the perfect solution as the approach to working method for strategic planning within the “Miljonprogram”. The model is a well-structured method that is much based on Swedish research. There would be a need for significant changes to the concept to be adapted to work in the specific areas. A solution could be to take a step back and rebuild a new model customised for the actual areas within the “Miljonprogram”.

    Innovation in construction engineering education: some experiences and a planned follow-up1999Ingår i: Byggandets ekonomi och organisation : nordiskt seminarium, Göteborg 12-13 april 1999 = Construction economics and organization : proceedings of the Nordic Seminar on Construction Economics and Organization 12-13 April 1999, Göteborg, Sweden / [ed] Jan Bröchner & Per-Erik Josephson, Göteborg: Department of Management of Construction and Facilities (Institutionen för byggnadsekonomi), Chalmers tekniska högskola , 1999, s. 227-232Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper describes an attempt to include a course, “Innovation”, in an educational programme for construction engineers. This course has been divided into two parts; part 1 which is entirely theoretical, and part 2 which mainly consists of a project. The course has been given during six academic years and the response from the construction engineering student has been mainly positive. Some of the projects have resulted in feasible new products. The intention is to execute some research within the field “Innovation in Construction” with this course as a starting point.

    Arbetsmiljö och säkerhet: På mindre företag inom byggindustrin2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The accident frequency in the construction industry has shown a downward trend every year but this trend was broken 2010th. It is often lack of precautionary measures within work environment and safety that is the cause of accidents. The big construction companies understand the importance of precautionary measures within work environment and safety, as they spend a lot of money and time on that matter. By examining the work environment and the safety of the small construction companies you can see how they work. The report will presents how these small companies work with work environment and safety, and also how they follow the safety instructions that are available and how they make use of safety equipment. By making use of interviews with staff in small construction companies, information has been collected about how they work with work environment and safety, and how they experience them. An interview with inspector at Swedish Work Environment Authority has been done to get their point of view of the small construction companies. The results show that small construction companies can get better at planning the work environment before construction begins. The constructions sites were kept clean to avoid falls. It appeared that they sometimes didn’t use harness at small jobs on the roof, but on larger work on the roof they used scaffolds. The reason to the sloppiness of not following the safety rules were time pressure and fast pace.

    PlusTak2010Studentarbete övrigt, 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Dagens takläggning vad gäller bostadshus är en tidskrävande process, där många olika steg ute på arbetsplatsen fordras vilket kostar mycket tid och pengar. Dessutom blir resultatet inte alltid vad man kunnat önska och röta och mögel är ett vanligt inslag på dagens vindar.

     

    Modulkonceptet har redan fått ett rejält genombrott inom nybyggnation av bostadshus, och prefabricerade husgrunder och väggar i modulform produceras och används idag i stor utsträckning. Detta modultänk effektiviserar byggnationerna avsevärt där man får det att fungera. Vad ingen tidigare lyckats med är att utveckla ett motsvarande taksystem som uppfyller alla de krav som ställs när det gäller bostadshus. Målet med Plustak har alltså varit att ta fram ett fullgott modulsystem för bostadshustak som uppfyller de nordiska kraven.

     

    Under projektet har projektgruppen lagt mycket tyngd på kundkontakter och användarvänlighet av produkten, både under tillverkning och på byggarbetsplatsen. Denna utveckling har gått hand i hand med en rad praktiska tester och försök. Projektgruppen har även varit med och lagt PlusTak vid flera tillfällen under våren för att vidareutveckla produkten ytterligare. Resultatet är ett komplett taksystem som är nästintill helt prefabricerat, och endast ett fåtal timmar krävs för att lägga ett helt tak på plats och erhålla en fullt väderskyddad byggnad. Plustak är mycket flexibelt och lämpar sig både för olika hus- och taktyper, och dessutom för nästintill alla taklutningar. Även som ytskikt finns olika utföranden i form av antingen klassisk bandtäckt plåt eller traditionella takpannor. Den goda isoleringsförmågan hos PlusTak gör att systemet väl uppfyller de krav som ställs på dagens lågenergihus. Att det isolerande skiktet dessutom är beläget ytterst i taket eliminerar kondensproblem som annars uppstår och som blivit ett växande problem för husägare. PlusTak erbjuder ett kostnadseffektivt taksystem som dessutom ger ett problemfritt takägande.

     

    Parallellt med utvecklingsprocessen av produkten har en offensiv marknadsföring bedrivits genom flertalet kanaler. I mars 2010 patentsöktes PlusTak, varefter det presenterades med stor framgång på Nordbyggmässan i Stockholm, nordens största byggmässa. I skrivande stund har PlusTak sålt för över en miljon kronor och offererats mot förfrågningar för över 40 miljoner kronor. Trots lågkonjunkturen motsvarar den årliga marknaden i Sverige minst två miljarder kronor och inom en femårsperiod räknar projektgruppen med att ha tagit över 2-10% av denna.

    Tillgänglighetsproblematik inom Byggsektorn2016Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this report was to investigate the problems experienced by a variety of professions in the construction sector regarding the requirements that exist today and is set to accessibility during construction.

    The study was conducted in the form of semi structured interviews, to find out the problems experienced by different professions. Interview respondents consist of those working as local manager, project developers, landscape architect, land planner, constructor, fire engineer and architect.

    The result obtained shows that there are a variety of problem areas. Some unique to a profession, while others are commonly experienced and supported out of several different groups. Generally, it has been shown that there is no great understanding of each other and the problems experienced. The result mainly points out the problem that arises or will occur is affecting moisture. Regarding ground but also building technical details such as connections between the building and the balcony. Another large part of the result is of lack of space and the influence of the terrain and existing buildings. The economy has as always a strong impact.

    Shown by the result, moisture tend to be sidelined and often suffer from other requirements, this could lead to big problems in the future when many moisture related problems is hard to see right away but might be causing problems later on, such as mold growth. The requirements are spread across many different regulations and often make the project stage difficult. We believe that accessibility requirements are very important and are something we in Sweden can be proud of, but the pressure that has come in recent years has made it difficult for the construction industry to keep up with and acclimatize. To create a sustainable development all requirements should be considered.

    Abstract [sv]

    This is a diploma thesis executed as a part of the examination of the educationalprogram Building engineer – Construction management at Halmstad University. The aim of the thesis is to compare and evaluate conventional open-cut pipe-laying withhorizontal directional drilling. The thesis includes a comparison of the economic,environmental and time-based aspects of both methods and discusses which factorsthat determine the optimal choice of method.The study is mainly based on previous studies regarding the subject and oninterviews with professionals from the industry.A fictional project with five realistic cases of pipe-laying scenarios was compiled,sent to different companies for calculation, evaluated and compared. Our conclusionregarding when it’s suitable to use which method is entirely dependent on thespecific project. The different methods each have specific pros and cons and shouldbe evaluated regarding the projects economic, temporal and environmental demands.In bigger projects we see that a combination of the two methods can be suitable.

    Keywords: Horizontal directional drilling, trenches, open-cut trench methods,excavation, conventional trenches, pipe-laying, economic analysis, environmentalanalysis, time-based analysis

    Produktionschefens arbetssituation: Hur deras arbete kan förändras och utvecklas2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This report is written in cooperation with Skanska Sverige Hus Väst and it is discussing the role of site managers within the company. The report will bring up the demands that is put upon site managers and will also discuss stress related problems and how to change and develop the role as a site manager.

    We came up with three conclusions in this report. We believe that Skanska could develop VSAA to make it easier to use for site managers. We also believe that a further development of the project engineer is of great value, to give him or her greater responsibilities. The last conclusion is to change the responsibilities between the site manager and the production manager, to give the production manager a greater responsibility in the production.

    Användning av digitala verktyg i byggentreprenadbranschen: -En studie om hur ett totalentreprenadföretag kan digitalisera sig2018Självständigt arbete på grundnivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Abstract

    Purpose: The purpose of the thesis work is to investigate how to use digital tools more in building design and why it is not more used today. The purpose is also to investigate the knowledge and experience of using digital tools from an overall perspective from a full-time contractor.

    Method: This report has been done both on the basis of a quantitative and qualitative study. The quantitative study provides answers to research questions and provides a hypothesis of an expected result. The qualitative study poses questions about experiences and experiences that create a personal result.

    Result: The thesis clearly shows that it could have been a great advantage of increasing the use of digitization and digital tools in the design process of a construction company. The motivation exists with most officials, which is a major contributing factor in achieving their goals.

    Restrictions: The thesis is limited to viewing digitalization and digital tools from an overall perspective during the design process, and then only the design process and not the production. the company BetonmastHaehre Göteborg AB will also be in focus when the work has been done in cooperation with them.

    Consequences: The assessment is that there is a good chance of increasing the use of digital tools in the construction industry if companies are actively working on the issues that the employees have. At the time, the construction company can become more attractive to the market, both for new employees, new clients and those already established in the company.

    Energieffektiviseringens position i kommunala energiplaner: En kritisk granskning - på jakt efter det konkreta2010Självständigt arbete på avancerad nivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    År 1977 trädde lagen 1977:439 om kommunal energiplanering i kraft i samband med allt mer uppmärksammade miljöproblem. Detta innebar att alla kommuner i Sverige nu var tvungna att arbeta fram en plan för tillförsel, distribution och användning av energi. Planen skulle följas upp löpande och visa såväl genomförda som nya mål. Drygt trettio år har gått sedan dess och miljöproblemen har genom forskning visat sig allt mer hotande för varje år.

    Idag belyses energieffektivisering som en av de både mest effektiva och långsiktigt hållbara lösningarna på energianvändningens negativa miljöpåverkan. Dessutom är det till och med ofta lönsamt att investera i energieffektiviseringar. Rimligtvis bör dessa vara en viktig del i den kommunala energiplanen, men är de det? Arbetet redovisar i vilken omfattning som energieffektivisering prioriteras bland de kommunala målsättningarna och åtgärdsförslagen. Resultatet är att de allra flesta av energiplanerna borde vara mer i framkant än idag. Generellt saknas det förslag på åtgärder och många av planerna förlitar sig istället på övergripande mål om en minskad total energianvändning.

    En viktig slutsats av granskningen är att energiplanerna skiljer sig stort åt i såväl upplägg som målsättningar, vilket tyder på ett bristande samarbete kommuner emellan samt en oprecist formulerad lagtext. I en bedömning av de tolv energiplaner som granskningen innefattar kan vissa förefalla mer föredömliga än andra men utifrån lagen är det svårt att peka ut någon som oduglig eftersom lagens krav är mycket tolkningsbara. Urvalet av Västra Götalands 49 kommuner gjordes i samråd med Margareta Hallander med ambitionen att få en spridning av små och stora kommuner samt landsbygd och tätort.

    Examensarbetet visar även upp ett föredömligt tillvägagångssätt för att få en konstruktiv och motiverande energiplan som skapar förändring. Som grund till detta goda exempel ligger litteratur och egna åsikter.

    Impact assessment and project appraisal in cases of coastal erosion2010Ingår i: International Journal of Disaster Resilience in the Built Environment, ISSN 1759-5908, Vol. 1, nr 3, s. 297-309Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: There are several urban areas close to the sea and other water bodies that may be adversely affected by erosion and flooding. Global climate change, including sea-level rise and more intense and damaging storms, will increase the threats of natural hazards in several areas. Mitigating and adapting to these risks in urban areas are huge challenges for society. There is a need for a proper decision basis to build a society that is economically, socially, and environmentally sustainable. By incorporating coastal hazard and risk mapping into spatial planning, new developments can be diverted away from threatened areas. Further, by taking adaptation measures, risks in existing urban areas can be reduced. The purpose of this paper is to address these issues.

    Design/methodology/approach: This paper presents the results of two case studies and discusses the prerequisites for impact assessment and project appraisal and how this is used and accepted by the users and decision-makers.

    Findings: A guideline has been developed as a tool for the integration of costs and benefits in decision making on investments in coastal zones. The guideline gives an overview of why, when, and how impact assessments and project appraisals can be made using socio-economic valuations of coastal areas affected by erosion. Two case studies have been performed to demonstrate the practical application of the guideline and economic analysis and valuation in coastal management.

    Originality/value: The guideline can be used to prioritise areas that need attention due to threatened shorelines, and to decide which preventive measures are the most efficient from a socio-economic point of view.

    Cycling and cycling cessation in later life: Findings from the city of Malmö2016Ingår i: Journal of Transport and Health, ISSN 2214-1405, E-ISSN 2214-1405, Vol. 3, nr 1, s. 38-47Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study aims to gain a greater insight into cycling as an element of mobility among those in later life. The characteristics and views of those who cycle, those who have never cycled, as well as those who have discontinued cycling in later life are the main focus. Malmö, a city in the south of Sweden with a strong emphasis on bicycle planning, is the study area. This study employed a mixed methods approach. The quantitative element comprised a survey which aimed to capture the trends at play when it comes to cycling within this age group. The qualitative element encompassed two focus groups which were carried out in order to gain a deeper insight into older persons’ perspectives and perceptions with respect to cycling. The study׳s findings illustrate the very positive and important role cycling can play in the mobility of older persons in the city of Malmö. It is not only possible but also mostly enjoyable for many older people to cycle. Cycling is a facilitator of activities and is largely associated with convenience and ease. There are clear differences between cyclists and non-cyclists, with the former generally having a wider range of mobility opportunities available to them. Cycling cessation is anticipated as a very distressing, yet inevitable, life event by those who still cycle. The results of this study suggest that campaigns aimed at increasing the awareness and consideration of other road users towards older cyclists, as well as the introduction of clearer and more visible signage could support older cyclists in prolonging their cycling, as well as improving the experience they have as they do cycle. Increasing awareness of the health benefits of cycling could be another means of encouraging people to continue cycling as they age. © 2016 Elsevier B.V.

    Cycling in later life: To cycle or not to cycle2015Ingår i: TRANSED 2015: Proceedings from the 14th International Conference on Mobility and Transport for Elderly and Disabled Persons / [ed] Rosário Macário, 2015, s. B335-B336Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The importance of introducing measures to increase the modal share of cycling has come to the fore in both policy and research in recent years. The benefits of increased cycling are wide-ranging; with cycling often considered to contribute to more attractive public spaces, increased safety, and more sustainable urban life.

    Different parts of the world are seeing an increase in the modal share of cycling. However, these increases are largely attributed to commuter traffic, with older persons somewhat underrepresented. There is, however, some evidence to suggest that developing strategies for cycling promotion across the lifespan, and particularly into later life, would allow people to continue travelling by bicycle as they age. While much is known about the car and the importance of the car in facilitating mobility in later life, much less is known about cycling and its role in the mobility of older persons.

    Employing a mixed method approach, this study aims to gain a greater insight into cycling as a mode of transport among those in later life. The study explores (1) the key differences between older cyclists and older noncyclists; (2) the perceptions of older cyclists in relation to cycling as a mode of transport; and (3) the factors which are associated with cycling cessation in later life.

    Malmö, a city in the south of Sweden with a strong emphasis on bicycle planning, is the study area. The city of Malmö is an interesting case as Malmö Municipality has put a strong emphasis on its aim for cycling to be apart of its inhabitants’ everyday lives.

    A survey aimed to capture the trends at play when it comes to cycling among those aged 65-85 living in Malmö city (N = 456). Two focus groups were carried out in order to gain a deeper insight into older persons’ perspectives and perceptions with respect to cycling. The focus group discussion guide comprised two main themes: ‘Reasons for cycling/not cycling’; and ‘The cycling experience in Malmö’.

    The key differences between older cyclists and older non-cyclists were focused around the factors of gender; health and activity; mobility opportunities; and life course and intentions.

    Cycling cessation was associated with those who do not participate in all desired activities, those who do not have access to a car in the household and those who do not associate cycling with health. The only variable associated with a higher odds of having ceased cycling was age, meaning that, by and large, the older the respondent the more likely he/she is to have ceased cycling.

    The study’s findings illustrated the very positive and important role cycling can play in the mobility of older persons in the city of Malmö. It is not only possible but also mostly enjoyable for many older people to cycle. Cycling is a facilitator of activities and is largely associated with convenience and ease.

    There are clear differences between cyclists and non-cyclists, with the former generally having a wider range of mobility opportunities available to them. Cycling cessation is anticipated as a very distressing, yet inevitable, life event by those who still cycle.

    The results of this study suggest that campaigns aimed at increasing the awareness and consideration of other road users towards older cyclists, as well as the introduction of clearer and more visible signage could support older cyclists in prolonging their cycling, as well as improving the experience they have as they do cycle. Increasing awareness of the health benefits of cycling could be another means of encouraging people to continue cycling as they age.

    Managing Resources in a Sustainable Building Process2013Ingår i: Proceedings of SB13 – Oulu, Finland: Sustainable procurement in urban regeneration and renovation Northern Europe and North-West Russia, 21–25 May 2013, Helsinki: RIL - Finnish Association of Civil Engineers, 2013Konferensbidrag (Refereegranskat)
    Abstract [en]

    Introduction

    Managing resources efficiently in a building process is of great importance in a sustainable development. The framework in a building process contains legislations and rules from a societal perspective combined with demands of a more efficient way of working within the companies involved. The knowledge of all actors involved must be used in order to solve this complex task. The quality of new buildings does not always match the expectations from the clients today so efforts must be done to improve the process. Another urgent issue is to deal with existing buildings. Participatory governance can describe the citizens’ democratic right to participate in decision-making concerning building or renovation processes. The public sector in Sweden discusses the possibilities of working more systematically with the ambition to use all the resources in a better way and with an end-user perspective. Today different processes seem to be parallel and do not always support one another. How can we achieve the best quality in the integrated process and in the end-product? Can a genuine dialogue and integrated processes be one way to achieve a better result? The case study evidence suggests that the primary focus of the logistics concept in construction is to improve coordination and communication between project participants during the design and construction phases, particularly in the materials flow control process.

    Problem

    The Building Industry faces challenges both in new building projects as well as when dealing with existing housing areas. The economical resources are limited and the regulations and restrictions are many. Examples from the Swedish building industry show severe problems with quality and how to manage the financing of the damages. The knowledge and awareness ought to be within all actors involved in the process but the question is if there are obstacles for using it? Where and when shall the resources be adopted to the process and which are the effect of a more integrated way of working? A gap can often be indentified between different processes and actors involved in this complex industry dealing with governing the built environment:

    Theoretical framework

    In the planning- and building process several kinds of flows are managed simultaneously. The flows are governed within and between the companies involved, the residents and the governmental framework of regulations and laws. If using a combination of theories from transport logistics, design methods and quality management maybe some of the existing gaps in the process could be avoided. The challenge is to see the possibilities in new demands in services and products. New skills, competences and attitudes are required when working with processes. It is also of great importance to create an understanding and acceptance for the changes. Starting with defining and focusing on the end-user in the process can be an important unifying force. Customer driven processes and a modern perspective on quality puts the end-users needs, expectations and requirements in focus. Using theories from the design area one could start with looking into Architectural design where decisions influence the artificial environment in our every day life. The act of designing is a complex activity undertaken a close cooperation with many other actors. There is a growing recognition of the importance to think more creative and dynamic by adding values and culture into the process If implementing the lean thinking philosophy and tools into construction industry one must include lean ideals and tools into the participating organisations. Eliminating waste and maximising value must be applied into the processes within the organisations as well as on site-based construction. Logistics activities commonly involve movement and storage for the purpose of having the desired object of at the right place at the right time. Transport, storage and distribution are cornerstones of logistics and its most visible manifestations. For the construction industry, logistics comprise planning, organization, coordination, and control ofthe materials flow from the extraction of raw materials to the incorporation into the finished building Several Swedish laws emphasize the importance of the involvement of residents and end-users in the planning- and building process. Communication and knowledge transfer can be used as a tool for combining parallel processes. Digital communication networks offer the possibility of better links between clients, designers, construction organizations and suppliers

    Case study results

    Three case studies are used to exemplify different levels of collaboration and integration between parallel processes. Case I and II was part of a doctoral thesis and the third case is an ongoing research project not yet documented.

    Case study analysis

    Case studies on large scale projects in Sweden shows that working with the end-users needs and requirements in focus can support the complex building process. Working in a more integrated way can support the complex mix of technology, people and decisions involved. Recourse logistics models and customer driven process methods can support the integration of parallel levels and phases in the process. The dialogue between the actors involved where experiences are shared can also give new and useful knowledge if it can be developed in a generous atmosphere.

    Conclusions

    Some experiences from three different case studies in Sweden shows that it could be possible to use more of logistic models and “Considerate Lean” models in the building and planning process. There is an opportunity to get long term sustainable housing by involving the residents and end-users and by using their knowledge in the process. Logistics require that all involved processes are communicating with each other. If not, the lean model will be hard to apply. Lean is about taking away all waste that is not used in the value added process. It concerns time, products, costs, etc. If this is done in a proper way it is possible to make a shift to a more value added process i.e. storing activities can be used for more productive and value adding work.
