affixed to the base 260 for instance by bolting the ballast 255 to the bottom surface of the base 260 consequently the ballast 255 can be used to shift the center of gravity of the base 260 to accommodate non level sites such as canal embankments in the like in a preferred aspect of the invention one or more engageable stabilizing pins 275 can be affixed to the base 260 so that when activated the engageable stabilizing pins 275 can inhibit the lateral or translational movement of the base 260 relative to the ground 240 and the columns 210 for instance referring to fig4 each engageable stabilizing pin 420 can be coupled to the frame 410 of the base of the template moreover leveling feet 430 can be coupled to the frame 410 so as to provide for vertical leveling of the base of the template in this regard an adjustable crank and shaft 440 can be configured to vertically adjust the leveling feet 430 so as to provide a control point for leveling the frame 410 referring again to fig2 to support the engagement of the columns 210 each of the pivotal column engagement scaffolds 295 include scaffolding supports 265 and a docking.
