         4 . The arrangement according to  claim 2 , the reinforcement bar provider further comprising a supply having at least one roll of reinforcement bar, the reinforcement bar provider being arranged to:
 select a roll of reinforcement bar having a dimension in accordance with said reinforcement cage information, and   retrieve a part of the roll of reinforcement bar, and arranged to bend, straighten, and/or cut the part in accordance with said reinforcement cage information.   
     
     
         5 . The arrangement according to  claim 4 , further comprising the at least one carrier robot being arranged to hold the part during bending and/or cutting of the part. 
     
     
         6 . The arrangement according to  claim 2 , the reinforcement bar provider further comprising a supply having pre-cut and/or pre-bent reinforcement bars, and
 the reinforcement bar provider being arranged to select pre-cut and/or pre-bent reinforcement bars from the supply in accordance with said reinforcement cage information.   
     
     
         7 . The arrangement according to  claim 1 , further comprising the reinforcement bar provider being arranged at a first side of the surface, a second reinforcement bar provider being arranged at a second side of the surface, and the second side being orthogonal to the first side of the surface. 
     
     
         8 . The arrangement according to  claim 1 , further comprising at least one holder arranged on the surface and arranged for receiving at least one reinforcement bar. 
     
     
         9 . The arrangement according to  claim 1 , further comprising a crane arranged to transport the reinforcement cage from the surface to a form. 
     
     
         10 . The arrangement according to  claim 1 , further comprising a protective tent arranged over at least one of the control unit, the reinforcement bar provider, the at least one carrier robot, the attachment robot, and the surface. 
     
     
         11 . The arrangement according to  claim 1 , further comprising the at least one carrier robot being arranged to acquire at least one image of reinforcement bars provided by the reinforcement bar provider, to compare the at least one image with at least one stored image, and to pick reinforcement bars in accordance with a result of the comparison. 
     
     
         12 . A method for producing a reinforcement cage comprising:
 a control unit providing reinforcement cage information relating to at least one from the group of position, order, and dimension of reinforcement bars in the reinforcement cage, and   an assembler assembling reinforcement bars in accordance with said reinforcement cage information, thus producing said reinforcement cage.   
     
     
         13 . The method according to  claim 12 , the assembler comprising a reinforcement bar provider, at least one carrier robot, and an attachment robot, the method further comprising:
 the at least one carrier robot picking reinforcement bars from the reinforcement bar provider and arranging the reinforcement bars on a surface in accordance with said reinforcement cage information, and   the attachment robot attaching the reinforcement bars arranged on the surface to each other in accordance with said reinforcement cage information.   
     
     
         14 . The method according to  claim 13 , further comprising the reinforcement bar provider providing reinforcement bars in accordance with said reinforcement cage information. 
     
     
         15 . The method according to  claim 13 , further comprising:
 the reinforcement bar selecting, from a supply having at least one roll of reinforcement bar, a roll of reinforcement bar having a dimension in accordance with said reinforcement cage information, and   retrieving a part of the roll of reinforcement bar, and bending, straightening, and/or cutting the part in accordance with said reinforcement cage information.   
     
     
         16 . The method according to  claim 15 , further comprising the at least one carrier robot holding the part during bending and/or cutting of the part. 
     
     
         17 .
