Re: Harold Brown pole structure - 2211 Dornoch - City Job #910086
We visited the above referenced site to verify pier construction, as backfills had occurred
without City inspection. We found the following:
1. The structure consists of a conventional 6x6 pole-framed, metal sided struciure with
manufactured trusses and crushed fock floor.
2. The concrete piers extend approximately 6" beyond the edge of the poles, indicating an
18" diameter bore.
3. Working a 112" diameter steel probe diagonally into the soil surrounding several piers
revealed an incompressible material of the same diameter as the pier top, to a depth of
about 30", where our probe met refusal.
4. The owner states that he had the holes bored bet\yeen 3' and3-1!2', and. backfilled with
'co',',""':",':' "'rI~ ""~ut ;';-'~l..jr(.....,th. :1~"U"........t,.,o"'; th.... ....~~~~v<;)t;on ;n.~nPr. tiO!1 W"S no' r~qlll'red

Based on items 2, 3, and 4, we conclude that the concrete pole embedment is 18" in diameter,
and at least 36" deep.
