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.
As requested by the client, ESNW rep was onsite to observe and test backfill of sewer main onsite.
Sewer Backfill
While onsite, ESNW rep observed the contractor backfill the sewer pipe. ESNW rep observed the
excavation to approximately 12’ deep. The sewer pipe was backfilled with pea gravel and backfilled with
gray-brown silt and sand with gravel. Each lift was approximately 12” thick and compacted with a hoe
pack. ESNW rep took compaction tests and found adequate compaction of at least 95% of the proctor at
the tested locations.
ESNW rep will return as requested to observe future earthwork activities.
