The building sites were staked
out with the 5 key stakes (rear, tips, front-center, and front-dish). If is important to locate these points
accurately. |
|
|
The rear and tip stakes were
then surrounded by 4 witness pins at 6 foot from the key stake. This is important in being able to find the
original stake-point once the hole is dug. |
|
|
A template was used to allow a
center starter hole to be dug prior to using the Dingo machine. This helped assure the Dingo bit began its
work at the right point. We removed the
template before using the Dingo as the Dingo would likely catch on it and
bust it apart. |
|
|
A Toro Dingo machine with a
18-inch wide bit and a 48” deep reach was used to drill the holes. This took 2 working hours with 3 people. Dingo cost was $114 for 3 hours. The Dingo bit would drift a bit and it
took some care to get the hole vertical and wide enough. |
|
|
The Dingo saved a lot of
back-breaking work in removing dirt from these holes.. |

A hole with witness lines strung
to check that the center is still good. |

Tube tested for center. |
|
|
Tube backfilled and
leveled. The lathe on the right was
used to set proper elevation using a level.
Our 2 sites were not at the same grade but we wanted each to be level.
Raised tubes will require more local fill before the slab is poured. |
|
|
Another tube backfilled and
leveled. Note this tube was at grade.
|
|
|
Final step! Rebar cage added, centered, and connecting
rebar shown to tie the footing to the slab. |
