Skyddsombudets Roll : En undersökning av skyddsombudets säkerhetsarbete på byggarbetsplatsen
Safety in the construction industry has become a question of top priority in recent years. Despite a massive investment of time, money and knowledge, the occur-rence of fatal accidents in Sweden alone is around one a month.The purpose of this study is therefore to improve the safety on the construction site. By an examination of the role of the safety agents and their cooperation with the construction workers and supervisors as well as examine how safety agents can improve safety on the construction site, which is the goal of the study.Four questions were formulated based on the purpose and the goal of the study.The methods used to answer the questions were a questionnaire survey, multiple interviews, a literature review and a document analysis.The report describes the safety agent?s role as a complex one with many different tasks. The role of the safety agents is regulated in the health and safety law, but it can sometimes be difficult to interpret and the agents can therefore interpret their role differently.
Frågeställningar vid ombyggnation av kontorslokaler till bostäder : Håltagning i plastgjuten betong
Det råder bostadsbrist i Stockholm, en lösning är att bygga nya bostäder. En annan lösning är att nyttja befintliga byggnader som inte används som bostäder, genom att bygga om kontor- och industrilokaler till bostäder. Det som händer är att industriområden flyttas längre ut från de attraktiva bostadsområdena. Ombyggnationer av byggnader med olika lokalkategorier kräver omfattande bearbetning och samarbete mellan flera aktörer såsom stadsplanerare, byggherrar, arkitekter, konstruktörer med flera. Det finns många aspekter att ta hänsyn till vid ombyggnationsprojekt och vårt mål är att belysa några av dessa.Den här rapporten studerar först och främst konstruktörens roll, vad en konstruktör ska tänka på vid en ombyggnation.
Säkrare arbetsmiljö på byggarbetsplatser : Hur brister på arbetsplatser borde åtgärdas för att kunna arbeta på en mer hälsosam arbetsmiljö
Work Environment problems on construction work sites are very extensive and discussed. The construction industry is one of the most dangerous industries in Sweden. The construction industry occupies about 290 000 employment (2009), and the investment was 250 billion SEK. This report will investigate the issues of the work environment and offer advice on how these can be measured and imporved. The study includes review and analyses of occupational injury statistics, interviews, inspections and audit and review of the literature.
Kunskapssyn och behov av IKT-verktyg
In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.
Hur skapar man en funktionell och beständig dörrmiljö? : En närmare studie av ståldörrar
Today?s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex.In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed.Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made.
Dimensionering av betongkonstruktioner : En jämförande studie av BBK 04 och Eurokod 2 vid dimensionering av balkar och pelare
Today, we use BKR and BBK 04 when designing concrete structures inSweden, which will, in the near future, be replaced by Eurocode 2. When you are designing buildings, you will use Eurocode 2 Part 1-1 and with this new standard, some new rules and general rules will be necessary to adopt. To examine how BKR and BBK 04 tells apart from Eurocode 2 when designing concrete structures, one beam and one column with often common dimensions, is studied. The beam is designed with consideration of (considerate to) durability at bending moments, shear forces and control of cracking. The column is designed with consideration of durability at eccentric axial load and bending moments in cross section on account of (due to) geometric imperfections. BBK 04 has gone one step closer to Eurocode 2 than earlier editions and the things that are different, when calculating reinforcement, is how they use the partial factors.
Tonala skillnader mellan en traditionell och en modern gitarrkonstruktion : En jämförelse mellan två klassiska gitarrer
During my studies to become a guitar builder at Carl Malmsten CTD, I have found an interest in the construction of the classical guitar. I am fascinated by the simplicity of its construction. A simplicity that becomes more complex when you start to study it in detail.In my final thesis I will not try to explain this complexity. The subject is to investigate two different principles regarding its construction. I would like to find out if the sayings concerning one of the principles will yield a guitar with greater ability to produce volume and projection.At a close distance the difference between the guitar?s volumes is not to speak of, but a significant difference can be seen regarding one of the guitars ability to project its sound.
Koldioxidutsläpp vid vägbyggnad - en fallstudie med jämförelse av alternativa byggnadssätt
Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.
Värdering av föroreningsrisk - Ett förslag till angreppssätt för värdering av föroreningsrisk till följd av emission från en vägkonstruktion
When constructing a road the risk of emission of substances from the used materials to the surrounding environment has to be evaluated. The aim of this study is to present a proposal for how to evaluate the risk of contamination as a result of emission from the materials in a road construction. The study is based on literature studies, an inventory and a questionnaire that examines how experts in governmental agencies, industries and universities evaluate the risk of contamination. The inventory indicates that guidelines for evaluating the risk of emission from secondary materials in a road construction do not exist. The conclusions from the questionnaire are: that there is no common way to evaluate the risk of contamination as a result of emission from materials in the road construction, there is no uniform interpretation of the terms "minor" and "significant" risk of contamination and that the evaluation is subjective.
?Varför är jag här? Varför sitter jag med de här gubbarna?? : En kvalitativ studie om att vara kvinna i den mansdominerade byggbranschen
This study aims to look at female executives? view of their leadership in the male-dominated construction industry. The study is qualitative and focuses on the respondents' subjective perceptions. We have conducted six interviews with women in different companies whose positions within each company varied. Using theories of subjectivity, emotions, impression management and organizational structures, to support the analysis conducted, this study shows that there are obstacles for women in the industry, but it also shows that it seems to be facing a brighter future.
An assessment of public procurement of timber buildings : a multi-level perspective of change dynamics within the Swedish construction sector
The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.
Ni börjar väl dagen med morgonuppvärmning?! En Fenomenologisk studie om de anställdas upplevelse av friskvården på NCC Construction Sverige AB.
The aim of this study was to get a deeper understanding of how employees at NCC Construction Sverige AB experience health promotion activities. The purpose was to identify and uncover the process of meaning constitution concerning health promotion within each subjective individual. To achieve this deeper understanding the participants were asked to answer a carefully formulated phenomenological question in a self-report. The received reports where analysed according to the method of Meaning Constitution Analysis. The result showed that both office workers and construction workers exclusively refer health promotion to bodily functions even though there where some differences in type of activity they focused.
Utökad samverkan med leverantörer : - Partnering, en lönsam möjlighet i byggindustrin?
The construction industry has been heavily criticized in the past few years for its development of productivity compared to the manufacturing industry. In 2009 the Social Care Center developed a report that treated och criticized different errors within the construction industry. For instance competence, construction errors and performance had showned bad results which had to be improved. A common sentence within the building industry is that ?every project is unique?. Today it?s common for a construction company to have costs for material and services which exceeds two-thirds of the total cost.
Varbergs besökscentrum - Nybyggnation
This report deals with activities that from a CSR perspective are considered to create a shared value for a medium-sized construction company in Sweden. The CSR definition used in the report is the European Commission?s since it reflects the valuecreating aspects of CSR, in contrast to the traditional philanthropic aspect of CSR.Companies in the building construction industry have difficulties identifying activities that create value in society and in the company. The aim with the project is to, from a CSR perspective, identify and evaluate value creating activities in a building construction company. The activities will be evaluated with respect to competitiveness and how they can be implemented into an organization.
Skanskas säkerhet på arbetsplatsen : Personlig skyddsutrustning
This degree projekt deals with Skanska´s safety at the construction site with focus on personal safety equipment. The purpose of this dissertation is to examine how the rules of personal safety equipment are applied and experienced at Skanska´s construction sites.In October 2004 Skanska started a projekt to make the construction sites more safe. With use of a questionnaire we have made a survey at different construction sites. 80 questionaires have been handed out to Skanska´s employees in the southeast region. While they were handed out we conrolled if the employees at Skanska´s construction sites used head protection, easy visible clothing, safety shoes and identification cards.The result of the survey shows how the rules are applied.
