Supplementary Report:
At the client’s request, ESNW rep was onsite to observe and test fire line backfill and slope stability.
Roof Drain Trench:
ESNW rep observed contractor using a medium sized excavator to excavate a 150’ long 3’ deep trench for a roof
drain with 8’’ pipe along the west margin of the main building. Rep used a ½” steel t-probe and observed the
subgrade to be very dense, firm, unyielding, and suitable for support of the proposed roof drain. Rep observed
contractor backfill with 18’’ of pea gravel and then 1’ lifts of native material compacted with a jumping jack to grade.
Moisture levels (approx. 20-28%) were too high above the optimum moisture for adequate compaction to be
attained. ESNW rep. communicated this with the foreman and recommends leaving the material undisturbed and
re-evaluating at a later date
Water Main Trench:
ESNW rep observed contractor using a medium sized excavator to excavate a 30’ long 7’ deep trench for a 12’’
ductile steel water main connecting to manhole 21 North margin of the stormwater vault. Rep used a ½” steel t-
probe and observed the subgrade to be very dense, firm, unyielding, and suitable for support of the proposed
water main outlet. Moisture levels (approx. 20-28%) were too high above the optimum moisture for adequate
compaction to be attained. ESNW rep. communicated this with the foreman and recommends leaving the material
undisturbed and re-evaluating at a later date
Cut Slopes
While onsite, rep observed slopes of the cut slopes to be near vertical. Rep observed that the north slopes of the
excavation were near a 0.75:1 (H:V) slope. Although over-steepened, slopes are stable in current configuration
and stable to work within. The contractor is responsible for providing all safety measures in accordance with state
and federal regulation
ESNW rep will return to observe earthwork activities when requested by client
