9.2 All excavations shall be performed to neat lines and grades as indicated on <br />the Drawing, as specified herein or as designated by the Engineer. Any <br />over excavation or excess excavation not requested or authorized by the <br />Engineer shall be at the expense of the Contractor. <br />9.3 It is the responsibility of the Contractor to maintain the required layback <br />slope of structural or trench excavations to meet applicable MSHA and/or <br />OSHA safety requirements. <br />10 HANDLING AND PLACEMENT OF EARTH MATERIAL <br />10.1 GENERAL <br />10.1.1 Earth materials shall be handled, transported and stockpiled in <br />such a manner as to prevent any undesirable segregation of or <br />intermixing of various types of earth materials. <br />10.1.2 Earth materials shall be placed in near horizontal layers to the <br />specified lift thickness. Distribution and gradation of materials <br />throughout the layers shall be such that the placed materials <br />shall be free from segregated lenses, pockets, streaks or layers <br />of materials differing in texture or gradation from surrounding <br />material. <br />10.1.3 Successive loads of earth materials shall be dumped so as to <br />provide the best practical distribution of material. <br />10.1.4 If the surface of any layer of rolled fill is too dry or too smooth <br />to bond properly with the layer of material to be placed thereon <br />or has formed a hard compacted crust from traffic, it shall be <br />moistened to optimum moisture and scarified as required <br />before the succeeding layer of material is placed. <br />10.1.5 The removal of wet or soft materials shall be carried to such <br />depth as determined by the Engineer to expose firm materials. <br />The exposed surtace shall be scarified or lightly disked in order <br />to provide an adequate bond for the subsequent layer of fill. <br />10.1.6 At abutments and/or against previously placed fill, each lift <br />shall be benched into the existing slope to provide a suitable <br />bond between existing and new materials. <br />SPEC.
