The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Stockholm is constantly growing and changing. Despite this, for various reasons, it is difficult to execute large building projects. With starting-point in decision making theories we have tried to investigate these difficulties. More specifically we have chosen to study why it has not been possible to rebuilt Slussen in Stockholm. To help us structure our study we have based our research on another large comparable building project, the Globen City project.

This paper is written as an examination paper at the University of Jönköping. The subject is chosen by Peab Sweden in Jönköping with whom further cooperation has been hold. The aim is to compare building methods and building materials in Sweden, Finland and Germany for further inspiration for Peab?s own market.BackgroundThe development of the construction industry develops new materials and methods to the market which has been forced by shorter construction times and the environment aspect. To pursue the development, further knowledge exchange should exist between the countries.

The construction industry accounted for 19 % of all work-related fatalities in Sweden between 2010 and 2013. The exam report has been done to find out what underlying causes there are to the high number of fatalities and to the occupational statistics of the construction industry. Moreover it has been reviewed what improvements can be done to reduce accidents and fatalities in the construction industry. The report consists of a survey of statistics, laws and regulations affecting the work environment and of literature concerning the subject. It has been conducted an interview and a questionnaire survey at the construction company Asplunds Bygg and an interview with an inspector from the Work Environment Authority.

This has been a thesis work for an bachelor degree at Umeå university. The work has been done at LKAB?s facilities in Kiruna and its main purpose has been to investigate and construct some conceptual designs for replacing a screen with magnetic separation in KA3 concentrator plant. First all information available about magnetic separation was gathered and studies of magnetic separation at the sorting plant and studies of the plant KA3 was conducted. Companies that manufacture magnetic separators were contacted.

Syftet med rapporten är att skapa en förståelse om vad BIM är och undersöka vad BIM för med sig i projekteringen. Det som kommer behandlas är BIM-samordnarens uppgifter, de olika negativa aspekter som påträffats vid användandet av BIM samt en presentation av olika program så kallade verktyg som används vid BIM-projektering. .

In our thesis we will compare interior walls, both bearing and non-bearing. All of thewalls analyzed are currently used in production by Skanska Construction, who is alsoour employer/supervisor for the project. The different wall types will be comparedfocusing mainly on time, cost and workability. All of these walls aside from the nonbearingwall are constructed using concrete, either prefabricated or cast on site..

Efforts to achieve a moisture proof construction process have proved to be considerably complicated, despite the knowledge and awareness that now exists within the moisture field. Materials, documents, templates and checklists are designed to be accessed but are not used anyway. This may be because such effort has not been prioritized and properly requirements have not existed from the commissioner of a building.This report illustrates how the commissioner of a building project can achieve a moisture proof building process by increasing knowledge, moisture proof planning, and implementation of security moisture routines. Proposals are given on how the commissioner of a building project can work to consistently bring a moisture proof building process in all stages. The difficulty with regular moisture proof efforts, the authors believe is mainly due to the following points:      Many different design solutions.      Lack of experience feedback.      Lack of communication.      Financial incentives.      Attitudes.The interviews in the report have conducted with the help of a qualitative analysis, while the survey has been done using a quantitative analytical method.

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.

Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.

?Optimizing the workflow of hydraulic reservoir tanks? is a degree project made by Jonas Olsson, student within the faculty of technology and science, during spring semester 2012. The project comprise 22,5 ECTS.Volvo Construction Equipment, located in Arvika, was the client in this project. The mentor at Volvo CE was A?sa Barck, and the mentor at Karlstad University was Monica Jakobsson.

The construction industry is currently receiving much criticism for inefficiency and slow development while demands for reduced built in moisture and efficiency increases. This report examines whether the use of field factories can meet these requirements and what factors that will be critical for future use of field factories. Industrialized construction with field factory is compared with traditional loose timber construction and industrial construction in the fields of execution, logistics and working environment. The aim of this report is to provide a basis for field factories current and future use and development. To achieve the aim of the report, people with experience in the use of the various methods was interviewed and literature studies in the various fields done.

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.

In the spring of 2009 Silva Sweden AB was contacted for a collaboration within the scope of a MasterThesis project. The company had discussed the possibility to develop a device that monitors usermovement during different types of exercise. The objective of this Master Thesis has therefore been todevelop and design a multi training device that records the user?s physical performance during severalactivities. The purpose of the thesis project has been to use scientific methods for product development inorder to design a multi device that supplements Silva?s range of products.The project followed a product development process divided into four phases; Market Analysis, ConceptCreation, Concept Development and Construction.

The mistakes and failures on the roof are noticed during inspection of the construction, many of the commentaries are recurring. A contractor should only need to get a commentary once and then learn from the mistake. It has in this study been brought to light that the solution is not to tell the contractors to "stop slattern", it is more complicated than that. Today, the biggest problems are found in leadership, communication, feedback of experience and that the entrepreneurs take too little responsibility.To minimize the amount of commentaries all contractors need to work with a clearer leadership where the leader is both respected and appreciated. The leader must in an effective way be able to convey all the information to all employees.
