Observations/Finding

As requested, the site was visited by our AS Engineering and Consulting (ASEC) representative for the purpose of providing quality control inspection and testing services.  Visual observation techniques were employed to verify compliance with project drawing/specifications, applicable codes, and materials submittals. The following observations were observed on site this day.

Our ASEC representative was on site as requested by the contractor (Wilbanks) for the observation/testing of the placement of fill/backfill.

The contractor placed a lift of soil, approx. 8in to 12in in thickness, across the approx. location of lots #64 -#69. The contractor compacted the lots via a sheep-foot roller and also rolled in the lift with a loaded truck. The technician density tested this area. This area appeared stable during proof-rolling. The contractor continued placing topsoil along the greenspace located on the edge of these lots.

The contractor began excavation of Lots #148 through #152. These lots were cut to an approximate elevation of 776.25. The technician observed the contractor proof-roll these lots. There were two areas (one on Lot #150 and one on Lot #152) that showed signs of pumping/deflection. The contractor cut out approximately a 15ft x 20ft x 3.5ft (depth) for each soft spot. The technician generally probed these areas during the excavation. The contractor then placed suitable material back in the excavations, in two lifts, that were compacted via a loaded tandem-axled dump truck. These areas appeared stable with generaly probing.
