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.

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.

Analys ac konstruktionsprocessen inom FTC
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.
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.
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.
Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff
In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.
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.
Konstruktion av steghållare till brandbilar
High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

BIM Building Information Model : Hinder & Drivkraft
The construction industry is a costly business such in respect of capital for most construction defects which then require rework, tear down and rebuild again. This study is meaningful awareness of tools that can reduce this best through communication and information sharing between the parties. The construction industry is known as temporary projects organizations, where the construction project consists of several actors who have to communicate and share information between them to avoid mistakes later in the build time. These actors are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to create a routine for the association and the shattering of these actors. To implement such behavior using a tool such as BIM in the industry whose size perhaps is indescribable may be a very hard task. BIM (Building Information Model) could be seen as the solution to this problem because it acts as a portal where the actors involved must sign in and communicate, share information, and eventually create a behavior, a routine for this association and division of the actors following the end of the project. The technology could help the involved from the beginning of the project, already in the model stage, break down and prevent any construction barriers when the building has been placed in the works.
