C. All geosynthetic materials underlying the berms will be inspected and approved <br />by the QA/QC CONSULTANT prior to placement of the general earthfill. <br />D. During all compacting operations, maintain optimum practicable moisture content <br />required for compaction purposes in each lift of fill. Maintain uniform moisture <br />content throughout the lift. Insofar as practicable, add water to the material at the <br />site of excavation. Supplement, if required, by sprinkling the general earthfill. At <br />the time of compaction, the water content of the material shall be at the optimum <br />moisture content, ±4 percentage points per ASTM D1557. <br />E. Do not attempt to compact general earthfill material that contains excessive <br />moisture. Aerate material by blading, discing, harrowing, or other methods, to <br />hasten the drying process. <br />3.18 DITCHES AND TRENCHES <br />A. Place general earthfill, as necessary, and excavate ditches and trenches to achieve <br />grade and dimensions shown on the Construction Drawings. <br />B. Excavate, as necessary, to repair any existing drainage structure damaged during <br />construction. <br />C. Minimum width of trenches shall be 12 -inches greater than outside diameter or <br />width of pipe. Maximum trench width is unlimited, unless otherwise shown or <br />specified, or unless width will cause damage to existing facilities, adjacent <br />property, or completed work. <br />D. Pipe bedding grooves shall be semi circular, trapezoidal, or 90 degree V. The <br />grooves shall be excavated or plowed into the trench bottom. Forming groove by <br />compaction will not be acceptable. <br />3.19 SLURRY CEMENT MIXTURE <br />A. Place slurry cement mixture at the locations shown on the Construction Drawings. <br />B. The EARTHWORK CONTRACTOR shall repair or replace any materials <br />damaged during placement of the slurry cement mixture, at the EARTHWORK <br />CONTRACTOR's sole expense. <br />3.20 CONCRETE <br />A. Construct concrete at the locations shown on the Construction Drawings in <br />accordance with the provisions in CalTrans Standard Specification Section 90-10, <br />Minor Concrete. <br />3.21 PIPE SUPPORT AND PIPE CLAMP <br />A. Install at the locations shown on the Construction Drawings. <br />Forward Landfill WMU FU -06 <br />02300 27 EARTHWORK <br />
