This is a degree project performed at Halmstad University in Sweden on the subject carpet of reinforcement. This project is developed in association with Celsa Steel Service in Halmstad. The purpose of this report is to investigate how much time that can be saved if carpet of reinforcement is used instead of the traditional way to work with reinforcement and see what kind of parameters that is important between the choices. We are also going to see how this product affects the situation for reinforcement workers from an ergonomic point of view. Carpet of reinforcement is made by straight reinforcement’s bars that are welded together with steel bands. These rolls are made at a factory with a machine that welds together the bars in determined centre distance, with desired dimensions after the construction engineers’ blueprints. The big advantage is that the work at the construction site becomes much easier. Also the number of reinforcement workers and the total time of the project can be reduced. All this together saves money. The soft parameters like work environment are also affected in a good way. The rolls are heavy and have to be lifted with a construction crane which saves the reinforcement iron workers body. The traditional work with reinforcement involves a lot of heavy lifting and trying work positions for the workers. Therefore is it fairly usual with wear injuries in the trade. We think that carpets of reinforcement may reduce the amount of wear injuries. Most of the workers that we interviewed seem to like the product. There are two different products that Celsa Steel Service provides the trade with. Bamtec is the oldest of these products and also the most common and appreciated. In connection with building of bridges it is forbidden to weld together the reinforcement because of the risk of fatique fractares in welded zones. Because of this, Bamtec can not be used in bridges. For use in bridges a new product called SpinMaster, without welding, has been developed. Carpet of reinforcement works best at large simple foundation slabs but can also be used in walls.
