C. Quality Control: <br /> I. General: As the Coarse Gravel material is being placed, the QA/QC <br /> Q <br /> CONSULTANT will be monitoring the construction activities and soil <br /> properties. If acceptance tests conducted by the QA/QC CONSULTANT <br /> indicate that the Coarse Gravel does not meet specified requirements, the <br /> EARTHWORK CONTRACTOR shall terminate material placement until <br /> corrective measures are taken. <br /> 2. Coarse Gravel Acceptance: Final acceptance of the Coarse Gravel will be <br /> based on all tests made on completed Work or on samples of material taken <br /> from the completed layer. Testing for final acceptance shall be performed <br /> by the QA/QC CONSULTANT in accordance with these Specifications and <br /> the CQA Manual. <br /> D. Protection: <br /> 1.

Constructed Coarse Gravel layer shall be maintained to meet the <br /> requirements of this Specification until final completion and acceptance of <br /> the Work. This shall include all measures to prevent erosion. During <br /> seasonal or other extended shutdowns, all exposed surfaces shall be <br /> protected as detailed in Article 3.1, PROTECTION OF EXPOSED <br /> SURFACES, of this Section. In addition, the Coarse Gravel shall be <br /> protected from any contamination that reduces the hydraulic conductivity. <br /> Any contaminated material shall be removed and replaced at no cost to the <br /> OWNER. <br /> 3.11 CONSTRUCTION OF GRANULAR DRAINAGE MATERIAL <br /> A. General Requirements: <br /> 1.

The CONTRACTOR shall notify the OWNER at least 3 working days in <br /> advance of when the granular drainage material is completed and ready for <br /> as-built surveys. The OWNER will survey the top of the GDM within two <br /> days of the layer being completed to determine that the required minimum <br /> thickness has been achieved. The survey shall be performed in accordance <br /> with Section 01410, SURVEYS, and shall provide coordinates and <br /> elevations of the surface at the established 75-foot grid and delineating <br /> prominent features such as the edge of GDM.
