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 on site to observe and test side sewer backfill and document Redi-Rock wall installation. Side Sewer Observations:
While onsite, ESNW rep observed the contractor excavating a sewer trench-line and installing side sewer for lot 1. The contractor excavated to an approximate 8-feet in depth while establishing trench boxes. The contractor installed an 8-inch diameter PVC pipe bedded in pea gravel. The contractor backfilled the
trench with native material in 12 to18-inch loose lifts and compacted each lift with a hoe pack. Density tests indicate adequate compaction of at least 95% at tested locations. Redi-Rock Wall Observations: ESNW rep observed the contractor install a Redi-Rock wall along the east side of lots 33 to 40. ESNW rep observed the excavation for the wall to be in dense material with a 1H:1V slope and was stable at the time of visit. The contractor placed a lift of blocks as per design schedule and used 5/8-inch clean crushed aggregate as drain rock/backfill. ESNW rep observed the wall to be installed as per approved plans and our geotechnical recommendations.
