1. A joist assembly system, comprising:
a support structure having a first level and a second level located at least partially above the first level;
a rigging table system located on the first level;
a plurality of material handling systems located on the second level above the rigging table system;
a plurality of welding systems located on the first level adjacent the rigging table;
a material supply station located on the second level;
a controller system comprising:
one or more memory components storing computer-readable code; and
one or more processing components operatively coupled to the one or more memory components, wherein when executed the computer-readable code is configured to cause the one or more processing components to:
communicate with one or more material handling systems of the plurality of material handling systems to pick a first upper chord portion and a first lower chord portion from the material supply station and position the first upper chord portion and the first lower chord portion on the rigging table system;
communicate with the one or more material handling systems of the plurality of material handling systems to pick two or more webs from webs in the material supply station and position the two or more webs onto the first upper chord portion and the first lower chord portion;
communicate with the plurality of welding systems to weld the two or more webs to the first upper chord portion and the first lower chord portion at the same time; communicate with the one or more material handling systems of the plurality of material handling systems to pick a second upper chord portion and a second lower chord portion from the material supply station and position the second upper chord portion and the second lower chord portion onto the two or more webs; and
communicate with the plurality of welding systems to weld the second upper chord portion and the second lower chord portion to the two or more webs at the same time.
