Supplementary Report:
At the client’s request, ESNW rep was onsite to observe and test fire line backfill and slope stability.
Domestic Water Vault:
Contractor placed 18’’ of pea gravel and then backfilled with brown silty sand with gravel native material around
domestic water connection vault. Rep used a ½” steel t-probe to probe the trench and observed the domestic
water line vault subgrade to be very dense, firm, unyielding, and suitable for support of the proposed domestic
water line vault. ESNW rep observed that the contractor had achieved minimum compaction standards of
95% or greater in locations tested.
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. ESNW rep observed that the contractor had achieved minimum compaction standards
of 95% or greater in locations tested.
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
