Abstract: This report is dealing with issues which have a high grade of attention in the construction business lately -non-value adding activities.A non-value adding activity can be defined as: a procedure which is done without achieving an increased value in the end product.Non-value adding activities can be divided into two categories.These are: non-value adding but necessary activities and non-value adding and eliminable activities.The necessary activities are procedures that have to be done even if they do not increase the value of the end product.The eliminable on the other hand are pure waste of time such as correcting mistakes, searching for lost objects and waiting for other procedures.According to earlier studies one third of the total project cost may be eliminable activities.In this report we have handled the non-value adding activities that can be connected to arrangement and structure on the work site.These activities might for example be: searching for tools, machines, material and information.To decrease the non-value adding activities we have had a goal to develop a template that can be followed to achieve a work site with a better structure and order.During studies of literature about the subject we came in contact with Lean Production.This is a production system which has the aim to eliminate different types of waste in the production.5S is the Lean Production method which we have mainly dealt with in this report.The name of the method is based on the five steps that are taken while working with the method; sorting, straightening, systematic cleaning, standardizing and sustaining.When introducing 5S the goal is to reach a work site that is functionally formed to minimize waste of time.It has also been shown that a well formed work site has a lower risk profile.At the beginning of the work with this report we made a study of literature concerning Lean Production and 5S.This was followed by a study visit and five interviews at a construction site in Halmstad.From the knowledge that has been received by theoretical and empirical data a template has been made.This template is a suggestion on how an introduction of 5S in the construction industry can be made.The template also includes several examples of changes which can be made at a construction site to improve the functionality.The report shows that the subject is considered relevant and in the right time.This is strengthened since the company we have been cooperating with has introduced pilot projects in other regions in Sweden.At these pilot projects the 5S-method has been used to improve the functionality and increase the safety at the construction site.This is done to reach a more efficient production with a lower risk profile.II III Förord Detta examensarbete har genomförts under våren 2012 och omfattat 15 högskolepoäng.Arbetet utgör avslutningen för våra studier på byggingenjörsprogrammet på Högskolan i Halmstad och har genomförts i samarbete med NCC Halmstad.Till att börja med vill vi tacka NCC Halmstad och alla på arbetsplatsen vi besökt för att vi fått möjlighet att genomföra detta arbete på ett smidigt och bekymmersfritt sätt.Stort tack till Morgan Ingvarsson, Torbjörn Wallenteim, Thomas Wallqvist och Jan Nilsson då de tagit sig tid till att genomföra intervjuer och delge deras kunskaper.Ett extra stort tack till Jörgen Olin som givit oss möjlighet till att utföra detta arbete och som genom arbetets gång varit tillmötesgående och ställt upp med både intervju och samråd.Ett varmt tack till vår handledare Bengt Larsson för en positiv attityd, bra handledning och goda tips under arbetets gång.Avslutningsvis vill vi tacka Fredrik Christiansson, Daniel Isaksson, Daniel Karlsson och Fredrik Lundvall för feedback och korrekturläsning.Vi hoppas ni finner detta examensarbete intressant och önskar er en trevlig läsning.
