1 <br /> 1 <br /> C. Protection of Persons and Property: Barricade open excavations occurring as <br /> part of this work and post with warning lights. Operate warning lights as <br /> recommended by authorities having jurisdiction. <br /> 1. Protect structures, utilities, sidewalks, pavements, and other facilities <br /> from damage caused by settlement, lateral movement, undermining, <br /> washout and other hazards created by earthwork operations. <br /> 1.05 TRENCH PROTECTION <br /> A. The Contractor shall construct and maintain sheeting and bracing as required to <br /> support the sides of excavations, to prevent any movement which could in any <br /> way diminish the width of the excavation below that necessary for proper <br /> construction, and to protect adjacent structures, existing piping and foundation <br /> material from disturbance, undermining, or other damage. Care shall be taken <br /> to prevent voids outside of the sheeting, but if voids are formed they shall be <br /> immediately filled and compacted. <br /> B. For pipe trench sheeting, no sheeting is to be withdrawn if driven below <br /> mid-diameter of any pipe, and no wood sheeting shall be cut off at a level lower <br /> than 1 foot above the top of any pipe unless otherwise directed by the Engineer. <br /> If during the progress of the work the Engineer decides that additional wood <br /> sheeting should be left in place, he may direct the Contractor in writing. If steel <br /> sheeting is used for trench sheeting, removal shall be as specified above, unless <br /> written approval is given by the Engineer for an alternate method of removal. <br /> C. All sheeting and bracing, not left in place, shall be carefully removed in such a <br /> manner as not to endanger the construction or other structures, utilities, existing <br /> piping, or property. All voids left or caused by withdrawal of sheeting shall <br /> immediately be refilled with sand or ramming with tools especially adapted to that <br /> purpose, by watering or otherwise as may be directed. <br /> D. The right of the Engineer to order sheeting and bracing left in place shall not be <br /> construed as creating any obligation on his part to issue such orders, and his <br /> failure to exercise his right to do so shall not relieve the Contractor from liability <br /> 1 for damages to persons or property occurring from or upon the work occasioned <br /> by negligence or otherwise, growing out of a failure on the part of the Contractor <br /> to leave in place sufficient sheeting and bracing to prevent any caving or moving <br /> tof the ground. <br /> 1.06 DEWATERING, DRAINAGE AND FLOATATION <br /> 1 A. The Contractor shall construct and place all drainage piping, structural fill and <br /> bedding rock, in-the-dry. In addition, the Contractor shall make the final 24 <br /> inches of excavation for this work in-the-dry and not until the water level is a <br /> 1 minimum of twelve inches below proposed bottom of excavation. <br /> 1 <br /> 05/08 02221-2 05-4893 <br />
