hole 1102 concrete 1410 has cured or u201c set u201d sufficiently that the concrete form cans 600 may be filled with concrete 1412 otherwise a little more time may be required prior to filling the concrete form cans 600 by filling the concrete form cans 600 immediately after pouring the hole 1102 concrete 1410 a continuous pour is achieved so that the concrete 1410 and concrete 1412 appear contiguous without a joint therebetween additionally by pouring in this manner there is only a single trip required for a concrete supplier thereby reducing costs and time at this point the concrete 1410 and 1412 is allowed to set for a period of time prior to removal of the concrete form cans 600 refer now to fig1 h where the concrete form cans 600 of fig1 g have been disconnected from the alignment jig 1000 the chords 800 detached and the alignment jig 1000 retracted alternatively but not shown here the chords 800 may be shortened in the retracted position while remaining attached to the alignment jig 1000 in this configuration the alignment jig 1000 may be readily hoisted from its present location to a new location refer now to fig1 i where the alignment jig 1000 of fig1 h has been removed leaving concrete 1412 surrounding load bearing members 1408 continuing into concrete 1410 in holes 1102 to form a tower footing 1414 finally refer to fig1 j where the footing 1414 of fig1 i has had a tower 1416 attached and power lines 1418 attached to the tower 1416 although the figures here have indicated a relatively flat site for locating a tower footing by means of elevated forms surrounding holes 1102 and corresponding scaffolding even highly sloping.
