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 installation of the dispersion trench onsite and to observe and
test the sewer line backfill.
Dispersion trench observations:
Upon arrival, ESNW rep. observed the grading contractors had
excavated the dispersion trench to a depth of -3.5' below
subgrade, with scarified sandy/gravelly material at the bottom of
the trench. The contractor is preparing to place geotextile filter
fabric. ESNW rep. observed that the contractor had installed the
perforated drain pipe and embedded it in the sandy/gravel
material and is preparing to backfill the area.
Sewer observations:
While onsite, ESNW rep. observed the contractor has installed side sewer pipes and a small manhole in
a shallow trench in the road onsite. ESNW rep. observed the contractor installed the sewer pipes and
embedded them in pea gravel. ESNW rep. observed the contractor preparing to place native soil as
backfill in the trench line and use a large hoe -pack to thoroughly compact the material. ESNW rep. took
compaction tests in the backfill around the manhole while onsite.
While onsite, ESNW rep. also collected a sample of the backfill
material for laboratory proctor analysis.
Compaction results:
ESNW rep. took compaction tests in the sewer line backfill after it
was placed and compacted. Density test results indicate adequate
compaction of at least 95% at the tested locations. The locations
of these tests are approximately shown on the attached plans.
ESNW rep. will return when requested.
