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 to observe the contractor and for the observation/testing of the placement of fill/backfill. The contractors removed approximately 20 feet to 30 feet (in length) of the unsuitable fill materials in the roadway on Garibaldi Street. The contractors went against ASEC recommendations and decided to bring soil from another site to use as fill in this area. ASEC did not have a proctor for this soil, so a field proctor was performed, and a sample was taken to our laboratory to perform a moisture-density relationship (proctor). The soil appears to be a silty material with a mixture of No. 57 stone. The contractor placed this material in approximately 8-to-12-inch lifts and compacted using a trench roller. Density testing was performed, and test results were provided to the contractor. The soil appears to be slightly higher than optimum moisture content, but the density tests were passing at this time. County officials were present onsite and stopped work due to lack of road plates and soil being placed on roadway.

A concrete pour of approximately 27 cubic yards was placed for the footing for the retaining wall located at the entrance of the site. Concrete testing was performed and test results were provided to the contractor. Six (6) cylinders were cast and stored on site, and will be transported to our lab on the following day.  The initial slump test of the first truck was approximately 7 inches which does not fall within job specifications. The concrete foreman was notified and requested 2 additional slump tests. Results of both slump retests were 7 inches.
