E. Removal of Muck, Rock and Other Unsuitable Material <br /> All muck, rock , clay, marl, gravel, boulders, heterogeneous fill material and any other <br /> organic or unsuitable "materials of excavation" encountered under pavement areas, <br /> structures and utilities shall be excavated and removed. Also any "unforeseen obstacles " <br /> such as buried trees or timbers, abandoned utilities, metal objects, concrete masses, or any <br /> other type of debris encountered shall be removed. <br /> All areas under proposed pavements or structures, which are indicated by testing to have <br /> more than trace amounts of silt and/or clay within the top several feet of existing grade <br /> shall be "proof rolled" using a vibratory compactor. Should the existing material <br /> continuously yield or "pump" during the proof rolling, the Engineer shall be notified and a <br /> determination made as to the amount of stripping needed to accomplish a stabilized <br /> foundation. <br /> Stripping shall be accomplished to clean in-place sand or other suitable material as <br /> approved by the Engineer. Removal of unsuitable material within areas which are to <br /> receive footings, slabs or other foundations shall be completed for the full area under such <br /> structures and to ten feet minimum outside the maximum perimeter. Where pavement is to <br /> be placed, said removal shall include all area under the surface and extend to the outside of <br /> any shoulders, under any sidewalks and bike paths, or as directed by the Engineer. <br /> All roots, stumps, logs, limbs, timbers, boulders, or any material which is not suitable for <br /> backfill material shall be removed from the site promptly and excavated and disposed of by <br /> the Contractor at his expense. <br /> Removal of all "materials of excavation" and "unforeseen obstacles" will be paid for under <br /> the heading of "Excavation and Hauling". <br /> 3 . 02 PROTECTION <br /> A . Sheeting and Bracing <br /> Where excavations may endanger workmen, existing structures, utilities or other facilities, <br /> it shall be the Contractor's responsibility to immediately install and maintain adequate <br /> sheeting and bracing per OSHA specifications in order to protect said facility. No work <br /> shall proceed in such excavations until the sheeting and bracing has been properly and <br /> completely installed. The sheeting thus installed shall be removed as the work progresses <br /> or, at the discretion of the Engineer, be cut off below finished grade and left in place. <br /> Sheeting and bracing may be either steel or wood at the option of the Contractor. <br /> Sheeting and bracing shall be installed in a manner that will allow for removal without <br /> injuring or endangering workmen, the work, adjacent structures, and the like. Voids caused <br /> by withdrawal of sheeting shall be promptly and completely filled with sand and <br /> compacted to a degree equal to the surrounding soil . <br /> B . Drainage and Dewatering <br /> Provide for the collection and disposal of surface and subsurface water encountered during <br /> construction. <br /> 02302 — Excavation and Fill <br /> 02302 - 4 <br />
