Dear Bruce :
On Monday , December 28 , 1992 , Schofield Brothers was called to the
above referenced site to inspect the sewage system installation .
The contractor informed us that he had encountered suitable
material at a higher elevation than shown in the soil tests and
that they had placed the pits and stone in this suitable material .
Dave Mason and I observed sand in the sidewalls of the 2 pit
excavations at the top of the stone and in the bottom of the
precast pit liners .
In reference to Note #10 on the Site Plan , I climbed into the
western pit and dug a four foot hole verifying clean sand beneath
the pit and no ground water. I also had the contractor dig an
additional hole in the driveway near the eastern pit . We
encountered :
• 0 ' - 4 ' Hardening , subsoil and till
4 ' - 10 ' Medium coarse sand .
Based on this information and other information supplied by the
- contractor , it is our opinion that the pits are placed at a depth
not requiring a 10 foot perimeter excavation .
- In reference to Note #20 , the contractor also water tested the
D-Box in my presence and it was satisfactorily level .
Sincerely ,
SCHOFIE D BROTHE: S
