The posts were end-drilled to accept the 12" of rebar that was left sticking out of the 6 concrete piers that had been worked into the plan. The posts also had to have notches cut and holes drilled to accommodate the galvanized bolts which hold the whole structure together. The posts were then set on the piers with a large stainless steel washer to isolate the end of the post from any water on the concrete..
The arches were laminated from 5 pieces each 3/4" thick. Each morning we would clamp-up a new one, then the next morning mark out the bird's mouths and lateral strip locations, remove the arch from the form and start over again.
Arbors are decorative lattice type structures that creepers and vines can climb through and make it look more decorative. They make pleasing stand alone structures, also. Arbors create additional spaces for gardening, as they allow vines and climbers, to grow vertically through the latticework.
