8.7 - Application of Quality Level Analysis in the Acceptance
Determination
In addition to evaluation for conformance with the Engineering Limits identified above, the QC
and Acceptance test results for each Lot of Earthwork material will be continuously evaluated
using Quality Level Analysis (QLA) for the following Quality Characteristics:
▼ In-Place Density
▼ In-Place Moisture Content
The QLA for each Lot must indicate a Percent Within Limits (PWL) of 85% or higher, based
upon the Targets and Specification Limits indicated in the Table below, in order for the Work to
be accepted by Transportation Agency.

9.0 – Other Relevant contractor QC Plans
All Subcontractor and Producer QC activities for Earthwork are addressed within this QC Plan. There are no separate
Subcontractor or Producer QC Plans included as Appendices at this time.
In the event that separate Subcontractor or Producer QC Plans are submitted for Earthwork activity, this ABC
Contractors Quality Control Plan for Section 1 – Earthwork will be amended to include such Plans and resubmitted for
Transportation Agency approval.
