Reviewed By LAC Initials/Date SSR Initials/Date Field Supervisor Project Manager 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 on-site to observe and make recommendations regarding fence post excavations along the northern margin of the site. While on-site, the following was observed: Northern Fence Post Hole Excavation Observations & Recommendations: Upon arrival on-site, ESNW rep observed the grading contractor, Johansen Construction, continue excavating fence post holes directly behind the previously constructed fill rockery along the northern margin of the site. Per ESNW project manager, Scott Riegel’s, recommendations, the grading contractor carefully excavate a total of 37 pilot holes for the proposed fence posts along the northern edge. Each approximately 2-foot-wide by four-foot-deep excavation was observed to consist of previously installed rockery elements, including 2-man stones, 2-inch-to-4-inch clean crushed rock, Miragrid 5-XT geogrid, and structural backfill soil. ESNW rep observed the grading contractor carefully cut and remove localized sections of rockery elements (geogrid), taking care to not disturb other elements through-out the surrounding rockery section. Some sections will need to be re-excavated with larger machinery. These spots were marked by the contractor. Drain pipes with filter fabric were observed at the first 2 excavation sites and the sites along the western edge of the parking lot. Western Fence Post Hole Excavation Observations & Recommendations: Upon excavating the first section along the western edge of the parking lot, the drain pipe for the rockery was discovered to be 2 feet 8 inches from the surface and impeded the excavation process. This pipe was broken open during excavation on September 2, 2022 but contractor relayed to ESNW rep that they would be repairing it. ESNW project manager, Scott Riegel, recommended that the contactors cut through the pipe as they continue excavating and cap the ends of the pipe. The recommendation was relayed to the site superintendent who had an alternative suggestion, to shorten the shoring depth from 4 feet to approximately 2 feet and leave the drain pipe, or other utilities, intact. A total of 10 pilot holes were excavated for the proposed fence posts along the western edge of the parking lot. Excavation will continue on September 15, 2022.
