QUALITY CONTROL PLAN
SOIL STABILIZATION TREATMENT

The process of soil stabilization requires the teaming of a soil treatment specialty contractor working with the grading contractor to accomplish the project goal.

Due to the type of equipment required in the treatment process, the stabilization contractor is not always able to access the entire site on the initial mix. These areas include manholes, vertical edges, dead corners, and adjacent to underground utilities. These areas require that the grading contractor remove soil and reagent from these areas to an area nearby that allows initial mixing. The material then must be pushed back into place. Once this material is properly processed, the grading contractor can replace mixed soil back at its original location.

Job Setup – When setting up a treatment project the following information should be reviewed before scheduling:
- Job name and number

- Job location and project access

- Contact person ( Emergency contact #)

- Start time and curfews

- Type of treatment i.e.; parking lot, streets, pads

- Depth and percentage of treatment

- Available water meter

- Any special conditions

- Verify that "treatment" is included in USA or notify Griffin that another USA # is required and provide the coordinates.

Day prior to Treatment (before noon)

- Verify the depth, percentage, and square footage of treatment. (Tonnage ordered and delivered will be based on these verifications).

- Contractor should verify that there is no oversize material or obstruction in the treatment zone. Treated soils should not include any rocks or debris greater than 6 inches, with 90% passing the 1-inch sieve. (Caltrans jobs specs require 2.5 inch minus).
