foundations and other parts of the work in a state of dryness so as not to impede work activities, become <br />detrimental to related structures, or cause delays. <br />The Owner shall provide the dewatering system, if required. The dewatering system shall assure that the <br />adjacent facilities and any other work will not be damaged by dewatering operations. <br />Dispose of the water in a suitable manner without damage to adjacent property or without being a menace <br />to public health or without causing a public inconvenience or nuisance. <br />The water shall not be drained into work completed or under construction. <br />The dewatering operation shall continue until such time that it is safe to allow the water table to rise in the <br />excavation. <br />3.03 PLACING EMBANKMENT MATERIALS <br />No embankment material shall be placed in the fill area when either the material or the foundation or <br />embankment on which it would be placed is frozen. <br />No brush, roots, sod, or other perishable or unsuitable materials shall be placed in the embankment. <br />If the surface of the prepared foundation or the compacted surface of any layer of earthfill is too dry or <br />smooth to bond properly with the layer of material to be placed thereon, it shall be moistened and/or <br />worked with harrow, scarifier, or other suitable equipment, in an approved manner to a sufficient depth to <br />provide a satisfactory bonding surface before the next succeeding layer of earthfill material is placed. If the <br />compacted surface of any layer of the earthfill in-place is too wet for proper compaction of the layer of <br />earthfill material to be placed thereon, it shall be removed; allowed to dry; or be worked with harrow, <br />scarifier, or other suitable equipment to reduce the water content to the required amount; and then it shall <br />be recompacted before the next succeeding layer of earthfill material is placed. <br />The earthfill on each side of any structures shall be kept at approximately the same level as the placing of <br />the earthfill progresses, and the structures shall be protected against displacement or other damage. <br />3.04 WATER CONTENT AND DENSITY CONTROL <br />A. Temporary Construction Platform Fill Material <br />The Temporary Construction Platform Fill Material shall be compacted enough to support <br />standard slurry wall construction equipment. <br />B. Permanent Fill Material <br />The Standard Optimum Water Content is defined as "that water content which will result in a <br />maximum dry unit weight of the soil when subjected to the Standard Proctor Compaction Test as <br />described by ASTM D-698." Material shall have in situ water content no greater than 2% below <br />nor 3% above the standard optimum condition. Additional water as required may be applied by <br />sprinkling. <br />Each layer of earthfill material on the embankment shall be compacted as indicated in the section <br />in which applies to the material being placed. During compaction, the placement water content <br />and dry density of the earthfill shall be maintained within the control limits specified in each <br />section. <br />The water content of the earthfill material prior to and during compaction shall be distributed <br />uniformly throughout each layer of the material. As far as practicable, the materials shall be <br />brought to the proper water content by adding supplementary water, if required, to the material by <br />sprinkling on the earthfill and each layer of earthfill shall be conditioned so that the water is <br />0 1/06 Section 02290 - Page 3 of 4
