1. An apparatus comprising:
an integrated well construction system (IWCS) operable for constructing a well via integrated control of a plurality of integrated control devices that collectively control a plurality of integrated subsystems of the IWCS, wherein the IWCS comprises a processing system comprising a processor and a memory having a construction program thereon that, when executed by the processor:
controls each integrated control device, and thus each integrated subsystem, during each of a plurality of predetermined operational sequences;
prevents collisions between machines of the IWCS; and
prevents collisions between:
the IWCS machines;
tubulars being transported by any of the IWCS machines;
tubulars sticking up out of the well;
tubulars in a mousehole of the IWCS; and
tubulars in a hand-off position of the IWCS,
wherein the IWCS machines prevented from colliding by the construction program comprise:
a drawworks;
an iron roughneck;
a tong-handling trolley:
a tong-handling arm;
a catwalk;
a tubular delivery arm;
a lower stabilizing arm;
an upper tubular constraint;
an intermediate tubular constraint;
a lower tubular constraint;
a top drive;
a top drive elevator;
a fingerboard;
a transfer bridge racker; and
a setback guide arm.
