OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Sub grade improvements continued within proposed roadway areas located at the southeast side of
proposed building 2. The area was carried down to approximately 5' below finished grade (approximately
2' below the deepest utility invert) utilizing the Deere 450 excavator equipped with a flat cutting
edge (flared teeth) to minimize sub grade disturbance. Careful attention focused on utility grades and
layout to make specific accommodations for manholes and deep utility runs. The sub grade soil in this
area is fill, specifically tannin bark. Existing timber piles were encountered during excavation and
were cut off as necessary to avoid utility installation interference. Groundwater was present. De
watering was performed as necessary to maintain semi dry sub grade conditions. Excavation was performed
in small controlled sections to minimize water accumulation and sub grade softening. A layer of geogrid
was placed atop the sub grade to improve stability. Compaction of the sub grade will not be feasible
due to the wet organic sub grade soils. An approximately 12 - 18" thick layer of 2" crushed stone was
placed and graded. The surface of the stone was tamped into place utilizing the excavator bucket. The
area was filled placing approximately 18" thick lifts of 2" minus processed gravel. Each lift was
compacted employing a minimum of 6 passes of coverage utilizing the IR 10 ton drum roller exhibiting
stable/firm conditions. The work completed on this date was performed in accordance with the
recommendations provided in email correspondence by Kevin Martin of KMM; the geotechnical engineer of
record. The tannin bark and highly organic soils were segregated from the granular fill over burden
and stockpiled onsite.
