RE: Pile Inspection and Log for: O'Neal Residence 38 Sovereign Drive
Install date: 6/29
For your information, during the pile installation at the above referenced property, each pile was documented
for proper type and size of steel placement, correct grout mix, the number of strokes indicating volume and any
abnormalities that may have occurred during installation. Each pile was checked by "counting the strokes
method" as documented in several literature including "Inspector Guide to the Auger Cast -in -Place Piles"
published by the Auger Cast -In -Place Pile Committee of the" The Deep Pile Institute".
The approved drawings specified a 14" diameter auger cast pile drilled 29' in length. Each pile was drilled 30'
to account for any fill or difference in lot elevation. All piles were reinforced with 1#7 bar with 25' of pile
penetration.
The concrete pump used, a Transcrete BV75 was calibrated on site and determined to produce .65 cuft /
stroke. A digital stroke counter was provided on the pump.
The drilling equipment was fitted with gauges that were used to monitor and record the installation procedure.
These were monitored and/or reviewed to insure a positive head and adequate volume was maintained
throughout the grouting of each pile.
Attached is a detailed record of the pile volumes pumped into each pile. The lowest yield for any pile other
than for the pool area, was 110% which is consistent with the recommendations and meets the job
requirements as set forth in the structural drawings and soil report.
Based on this information, it is my professional opinion, the piles constructed for the referenced project were
installed in accordance with industry standards and as specified according to the construction drawings to the
best of my knowledge. The pile documentation and location plan are attached.
As indicated on the pile sequence page, one pile was omitted due to overhead obstruction with 2 being added
to take its place. This new placement is acceptable and works within the current grade beam design.
Please feel free to contact me if you have any questions.
Thank you,
