EARTHWORK <br />Section 02200 <br />15-1207 <br />E. Aggregate Base: Provide Class 2 3/4" Aggregate Base conforming to standard gradation as <br />specified in Caltrans Standard Specifications, Section 26,-1.02A. <br />F. Decomposed Granite: Decomposed Granite shall be well graded mixture of fine to 1/8" <br />particles in size with no clods. The material shall be free of vegetation, other soils, debris <br />and rock. The material shall be redish-tan to tan in color. <br />G. Decomposed Granite Solidifier: PolyPavement or equal. <br />PART 3 — EXECUTION <br />3.01 INSPECTION LAYOUT AND PREPARATION <br />A. Prior to installation of the work of this Section, carefully inspect and verify by field <br />measurements that installed work of all other trades is complete to the point were this <br />installation may properly commence <br />B. Layout all work, establish grades, locate existing underground utilities, set markers and <br />stakes, setup and maintain barricades and protection facilities; all prior to beginning actual <br />earthwork operations. Layout and staking shall be done by a licensed Land Surveyor or <br />Professional Civil Engineer. <br />C. Verify that specified items may be installed in accordance with the approved design. <br />D. In event of discrepancy, immediately notify Owner and the Architect. Do not proceed in <br />discrepant areas until discrepancies have been fully resolved. <br />3.02 PERFORMANCE <br />A. GENERAL: <br />1. General: Do all grading, excavating and cutting necessary to conform finish grade <br />and contours as shown. All cuts shall be made to true surface of subgrade. <br />2. Archaeological Artifacts: Should any artifacts of possible historic interest be <br />encountered during earthwork operations, halt all work in area of discovery and <br />immediately contact the Architect for notification of appropriate authorities. <br />3. Degree of Compaction: Percentage of maximum density, hereinafter specified as <br />degree of compaction required, means density equivalent to that percentage of <br />maximum dry density determined by ASTM D1557 Compaction Test method, and <br />such expressed percentage thereof will be minimum acceptable compaction for <br />specified work. <br />4. Optimum Moisture Content: Optimum moisture content will be determined by Soils <br />Engineer and this information supplied to Contractor. Optimum moisture content <br />shall be maintained until subgrade is covered by surfacing materials. <br />3.03 DEMOLITION, DISPOSAL AND DISPOSITION OF UNDESIRABLE MAN-MADE FEATURES <br />A.
