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 water main onsite.
Water Main Backfill
While onsite, ESNW rep observed the contractor backfill the water mainline. ESNW rep observed the
excavation to approximately 3’ deep. The sewer pipe was backfilled with pea gravel and backfilled with 1
¼” minus crushed rock. 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.
