Upon arrival, we met with the earthwork contractor. The driller had completed the timber lagging installation for the soldier pile wall and demobilized equipment. The void space between the back of the lagging wall and the cut was filled with 5/8- inch clean crushed rock. The earthwork contractor was in the process of installing the level spreader dispersion trenches along the toe of the shoring wall. The trenches were approximately 2-foot in depth and width (perpendicular to the wall face). Filter fabric was placed along the prepared trench excavations and pressure treated notched drain boards along the downslope portion of the dispersion trenches were placed. The contractor planned to backfill the level spreader trenches with clean crushed rock and then begin final grading of the area between the wall and the southern grading limits. We recommended the finished grade surface below the wall is protected from erosion through placement of jute mat and hydroseed for areas of exposed soil, the contractor agreed. We have been providing geotechnical consultation and construction monitoring services on a part-time basis. Our findings and conclusions are based on specific observations made while on site. Based on our observations, the level spreaders excavations were prepared in accordance with the project plans and our recommendations. We will continue to monitor site excavation.
