Align with the centers of terminal posts. Now, dig the post holes (normally 6 wide and 18 to 24 deep) and set the line posts. Before concrete begins to set, adjust post height by carefully moving post up or down in footing. Top of line posts should be even with string; outside face approximately 1/4 inside.
The hole for the footings should be below the frost line, as large as required by code (typically 16 inches in diameter and 8 inches deep for 8-inch-wide piers), and flared. Shovel or pour concrete into the hole until it reaches the top of the flared section. Take care not to disturb dirt on the sides of the hole.f you have already poured footings and the concrete is still wet, push the tubes an inch or two into the footings. Use a level to ensure that the tubes are plumb in the holes and level at the top. Begin backfilling by shoveling dirt into the hole around the outside of the tube.
