Inneluftsventileradekryprumsgrunder : en utvärdering av två tillverkare
This Diploma work investigates internal air ventilated crawl-space in respect to construction and damp. The Diploma work assumes from a general description of crawl-space and general dump problems in ground construction. An internal air ventilated crawl-space is a construction where you take the ventilation air from the building and bring it down to the crawl-space and lets the air circulate before it passes through a retaining aggregate on the way out from the crawl-space. In this matter you get a worm space under the building and a lot less dump problems in form of · Ground damp · Build damp The ground dump reduces through draining around the building, different layer of gravel between the ground and the building and ventilation of the crawl- space. The build dump reduces through ventilation of the crawl-space as fast as possible.
Framtagande av riktlinjer för arbetsplatsbesök enligt nya Plan- och bygglagen
A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.
INDUSTRIELLT EKOLOGISK STADSODLING : EN KVALITATIV STUDIE SOM UNDERLAG FÖR EN STADSODLINGSREVOLUTION I STOCKHOLM
Rooted in Industrial Ecology (IE) theory, this report evaluates how urban agricultural concepts and techniques, can contribute to improved ecological sustainability within the inner city boundaries of Stockholm. An overarching literary study as well as an interview was carried out, resulting in a qualitative analysis followed by suggestions for practical implementations. A substantial convergence was found between the eco-restructuring objectives of IE and the principal motives for urban agriculture. Consequently, eco-restructuring objectives are found in varying degrees in the presented urban agricultural techniques. Industrial symbioses, permaculture and combinations of urban agricultural techniques are tools which are capable of corresponding adequately to the diversity of urban settings.

Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews. The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.
Föslag till Estetisk Mångfald
I chose to do this work because I believe that today?s industrial designprofessionals lack in their task of creating aesthetic experiences and aestheticdiversity.With my work, I want to question why the majority of today?s technical, massproducedeveryday products have such a similar design expression, andwhy alternatives are so few. Most of all, I take a critical attitude to today?sstereotypical industrial design aesthetics that I would describe as technical,masculine, and unnecessarily complex.I have designed a number of products that show alternative aesthetics in thissegment and as such I have chosen the vacuum cleaner. The idea is that mydesign will serve as an eye opener and demonstrate that there are alternativesto today?s homogeneous market.The result is three vacuum cleaners claiming three alternatives to currentofferings.
Effektivisering : En utredning om åtgärder på en industrifastighet
AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses. This property currently has a high energy con-sumption and therfore it is desirable to improve the efficiency. In ordet to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss.
Observatörer för skattning av verktygspositionen hos en industrirobot : Design, simulering och experimentell verifiering
This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.
Identifiering av stelkroppsmodell för industrirobot
In this masters thesis we consider a method for experimental identification of the inertial parameters of an industrial robot, using measured torques and joint angles. A dynamic model of the first three joints of the robot has been identified.To achieve good identification results, it is important to carefully choose the trajectory for the experimental identification. A method to generate trajectories using two suggested design criteria has been used and evaluated using an ABB industrial robot, and one of them yields good identification results..

This thesis work was made to optimize the writing of the construction specificationsat FKA. These construction specifications are created before each plant modificationsthat is started because requirements from the Swedish radiation safety authority(SSM) and internally on Forsmarks nuclear group as constructions / implementationdocumentationThe study was done through seven interviews of two people at three different groupsinvolved in the construction specification and an interview from the group accreditedverification. The four selected groups were selected through an extensive analyticalwork resulted in an elimination matrix where these four groups was considered to bemost involved with the construction specification.The questions asked to these individuals were based on the instructions and sampletext that are described in the construction specification. To ensure the quality of thethesis were to limit itself to the chapters that were considered most relevant toimprove. The analysis revealed a number of points that should be improved, partlyinto the routines when writing the construction specification and when ether sampletext or suggestions should be changed and complemented.
Design av jolleindragare
This project has been about making a design suggestion for a boat accessory that adjuststhe distance between a sail-or motorboat and the dinghy, which is connected by a rope inthe stern. Today this is all done by hand and can lead to problems when it comes tostressful situations such as harbors and narrow passages.A company called Sailsafe came up with the idea and the construction, which they alsohave tested. I found them through an acquaintance at Dacat AB where I did an internshipin the fall of 2010.Using sketching as the primary tool I?ve worked in an almost-real design project with theaim to develop my skills and give the company a relevant design suggestion. Dacat thenhelped me with a 3d model in Alias, which was printed in 3d and painted in thepaintworkshop at school..
Nyanlända elever i fritidshem : En kvalitativ intervju om fritidspedagogers arbete med inkludering
The purpose of this study was to examine how pre-school teachers in Montessori inspired and traditional preschools can work with build and construction with the older children, and what views the pre-school teachers might have on the subject. The study was implemented through qualitative semi-structured interviews with pre-school teachers. The investigational method was chosen due to the fact that I wanted to gain knowledge about the pre-school teachers? views and perspectives on build and construction activities, and how they might work with it. Another reason was to examine how the view on, and the work with build and construction can resemble and differ between Montessori inspired pre-schools and traditional pre-schools.The result shows that there is both similarities and diverseness between the Montessori influenced pre-schools and the traditional pre-schools, when it comes to how the pre-school teachers reason and work with build and construction.
Verktyg för utveckling av terrängparker inom skidanläggningar. : Shaper
Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .
Byggprojektstyrning med Earned Value Management
AbstractToday, too many construction projects are delayed and deviates from the budget. Agood project management is the basis for successful construction project. The mostcommon planning methods in the construction industry is currently Gantt chart andCPM. The problem with these is that focus is only at the time of the project anddoesn?t handle the budget.
Ta bort tidstjuvarna! : Om tidsbesparande effektiviseringsåtgärder inom det kommunala bostadsföretaget Gavlegårdarnas byggprojekt
AbstractThe development of the construction industry is slower compared to other industries. This implies that there must be improvements in this field. One step to increased effectiveness in construction projects is making the construction process more efficient, therefore resulting in a positive result for both the actual construction project and for the overall branch. The purpose of this study is to identify areas for improvement within the municipal housing company Gavlegårdarna completed construction project, who will then contribute to increased efficiency in their upcoming projects. The work has been performed with the help of two case studies examine construction projects "Fullriggaren" and "The three nursing homes." Opinions about what could have improved the efficiency of these construction projects further have been collected with the help of an interview study among some of the project participants involved in both projects.There have been many studies addressing the topic of how the construction process can be streamlined and similar studies that have been previously conducted.
