Tasks and Critical Subtasks

Quality Standards Acceptable Quality Level Method of Inspection Penalties Incentives

Pre-Grading Roadbed Moisture Content (MC) Determination Blade roadbed when adequate MC is present.

Contractor shall apply water at their expense when moisture content is not adequate.

Adequate roadbed moisture content is between 5% and 15%.

Conditions are normally determined by visual observation.

Blading and shaping may be suspended when soil moisture conditions are not suitable for obtaining satisfactory results.

Accepted industry quality workmanship.

Adequate range of MC may be determined visually by Contractor prior to performance.

Visual verification. Contractor may be required to re-work, at their expense, the unacceptable section when the MC returns to within acceptable range.

Government may withhold compensation for that section.

Contractor may receive poor performance rating.

Contractor would receive a superior performance rating.
