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 South side of
proposed building 2. The area was carried down to approximately 5' below finished grade 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. 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. A sample of the fill overburden was collected and
transported to the UTS lab for sieve, proctor and organic content testing.
