         3 . The self-climbing screen system of  claim 1 , wherein the screed system is configured to be used with a self-climbing boom system that is a tower crane boom system or a placing boom system. 
     
     
         4 . The self-climbing screed system of  claim 1 , further comprising outriggers that are attached to the turntable and configured to rest on a floor of a building. 
     
     
         5 . The self-climbing screed system of  claim 4 , wherein the outriggers are retractable and extendable. 
     
     
         6 . The self-climbing screed system of  claim 1 , wherein the screed system is configured to be used with a self-climbing boom system having the boom connected to a top of the mast. 
     
     
         7 . The self-climbing screed system of  claim 1 , wherein the turntable is dismountable from the mast to detach the screed from the self-climbing boom system. 
     
     
         8 . The self-climbing screed system of  claim 1 , wherein the turntable includes tension links and pins that engage and disengage from the holes of the rail to mount the turntable to and dismount the turntable from the mast. 
     
     
         9 . The self-climbing screed system of  claim 1 , wherein the screed boom comprises:
 a first articulated boom section;   a telescopic boom section connected to the first articulated boom section; and   a second articulated boom section.   
     
     
         10 . The self-climbing screed system of  claim 1 , the screed further comprising:
 a counterweight connected to the turntable opposite the screed boom; and   wherein the turntable further comprises:
 a frame, the screed boom and the counterweight being connected to the frame; 
 tension links connected to the frame; 
 a roller bearing connected to the frame such that the screed boom can rotate 360 degrees; and 
 a pin configured to fit within holes of the tension links and engage with holes of the rails. 
   
     
     
         11 . The self-climbing screed system of  claim 1 , wherein the turntable is shaped to be radially spaced from an outer surface of the mast, forming a gap between an inner surface of the turntable and an outer surface of the mast. 
     
     
         12 . A self-climbing screed system for use with a self-climbing boom system that includes a mast that has a tower and a rail that is connected to an outer surface of the tower, extends along a length of the tower, and has spaced holes, comprises a screed, the screed comprising:
 a turntable configured to be positioned around the mast, the turntable including tension links and pins that are configured to engage and disengage from the tension links and the holes of the rail;   a screed boom having a proximal end and a distal end, the proximal end being connected to the turntable; and   a screed head connected to the distal end of the screed boom.   
     
     
         13 . A self-climbing screed system for use with a self-climbing boom system that includes a mast that has a tower and a rail that is connected to an outer surface of the tower, extends along a length of the tower, and has spaced holes, comprises a screed, the screed comprising:
 a turntable configured to be positioned around the mast;   a screed boom having a proximal end and a distal end, the proximal end being connected to the turntable, and the screed boom comprising:
 a first articulated boom section; 
 a telescopic boom section connected to the first articulated boom section; and 
 a second articulated boom section connected to the telescopic boom section such that the telescopic boom section is between the first articulated boom section and the second articulated boom section; and 
   a screed head connected to the distal end of the screed boom.   
     
     
         14 . A self-climbing screed system for use with a self-climbing boom system that includes a mast that has a tower and a rail that is connected to an outer surface of the tower, extends along a length of the tower, and has spaced holes, comprises a screed, the screed comprising:
 a turntable configured to be positioned around the mast, the turntable comprising:
 a frame having tension links; 
 a roller bearing connected to the frame; and 
 a pin configured to fit within holes of the tension links and engage with a hole of the rail; 
   a screed boom having a proximal end and a distal end, the proximal end being connected to the frame of the turntable;   a screed head connected to the distal end of the screed boom; and   a counterweight connected to the turntable opposite the screed boom;   wherein the screed boom can rotate 360 degrees around the mast.   
     
     
         15 . A self-climbing screed system for use with a self-climbing boom system that includes a mast that has a tower and a rail that is connected to an outer surface of the tower, extends along a length of the tower, and has spaced holes, comprises a screed, the screed comprising:
