1. A method for excavating a ditch and installing an underground pipeline therein comprising:
a) excavating a first ditch section of the ditch utilizing a predetermined global positioning system (GPS) model having grading and alignment requirements for the ditch and the underground pipeline,
b) inserting a first pipe and a laser beam apparatus associated therewith into the first ditch section,
c) projecting a laser beam from the laser beam apparatus utilizing the grading and alignment requirements of the predetermined GPS model for excavation and installation of one or more additional sections of pipes;
d) inserting a second pipe equipped with a remote-controlled vehicle into an excavated second ditch section and connecting the second pipe to the first pipe using the laser beam projected from the laser beam apparatus to guide grading of the excavated second ditch section and alignment of the second pipe with the first pipe;
e) inserting an additional pipe into an additional excavated ditch section and connecting the additional pipe to the second pipe by focusing the laser beam with the remote-controlled vehicle to maintain the grading and alignment requirements of the predetermined GPS model while excavating the additional ditch section and aligning the additional pipe to the second pipe;
f) navigating the remote-controlled vehicle from the second pipe to the additional pipe to guide grading of another ditch section and aligning another pipe; and
g) completing the underground pipeline by repeating steps e) and f) with one or more pipes.
