Limitations: The presence of our field representative at the site is to provide our client with a source of professional advice, opinions, and recommendations based upon the field representative’s observations and testing of the contractor’s work. Our services do not include supervision or direction of the contractor, their employees, or agents. Geotechnical recommendations for
obtaining project objectives may be made by our representatives; however, direction of the actual work should come from the owner or contractor, as appropriate. The contractor is responsible
for complying with the contract documents at all times, regardless of the presence of our field representative. Jobsite safety, including compliance with all applicable state or federal regulations,
is the sole responsibility of the contractor. The observations, recommendations, and conclusions provided in this field report are preliminary until reviewed by the ESNW project manager.
ESNW rep was onsite to observe the Redi Rock wall keyway and drainage, as well as observe and test
storm tie in backfill.
Redi Rock Wall Observations
ESNW rep was onsite to observe wall keyway. ESNW rep observed the contractor had excavated a
keyway approximately 5 feet in width into native grey silt with gravel. ESNW rep used a ½” steel T-probe
to probe the keyway and observed it to be very dense, firm, unyielding, and suitable for proposed Redi
Rock wall. ESNW rep also observed drainpipe along the back of the wall along the base. An 18” column
of drain rock was placed directly behind the wall blocks to the top of wall. ESNW rep will return to
observe continued wall keyway excavation.
Storm Backfill
ESNW rep observed the contractor had excavated approximately 3’ into native soils to place the storm
tie in to the vault. ESNW rep observed the contractor had sprayed the 1 ¼” minus crushed rock with
water and used a hoe pack to compact it with good effort. ESNW rep took compaction tests and
observed adequate compaction of at least 95% of the modified proctor at the tested locations. Please
