ll <br />t <br />1 <br />t <br />s <br />n <br />�J <br />C. Protection of Persons and Property: Barricade open excavations <br />occurring as part of this work and post with warning lights. Operate <br />warning lights as recommended by authorities having jurisdiction. Protect <br />structures, utilities, sidewalks, pavements, and other facilities from <br />damage caused by settlement, lateral movement, undermining, washout <br />and other hazards created by earthwork operations. <br />1.05 PROTECTION <br />1 07116 <br />A. Sheeting and Bracing in Excavations: <br />1. In connection with the construction of below grade structures, the <br />Contractor shall construct, brace, and maintain cofferdams <br />consisting of sheeting and bracing as required to support the sides <br />of excavations, to prevent any movement which could in any way <br />diminish the width of the excavation below that necessary for <br />proper construction, and to protect adjacent structures, existing <br />piping and foundation material from disturbance, undermining, or <br />other damage. Care shall be taken to prevent voids outside of the <br />sheeting, but if voids are formed, they shall be immediately filled <br />and rammed. <br />2. All sheeting and bracing not left in place shall be carefully removed <br />in such a manner as not to endanger the construction or other <br />structures, utilities, existing piping, or property. Unless otherwise <br />approved or indicated on the Drawings or in the Specifications, all <br />sheeting and bracing shall be removed after completion of the <br />substructure, care being taken not to disturb or otherwise injure the <br />finished structures. All voids left or caused by withdrawal of <br />sheeting shall be immediately refilled with sand by ramming with <br />tools especially adapted to that purpose, by watering or otherwise <br />as may be directed. <br />3. The right of the Engineer to order sheeting and bracing left in place <br />shall not be construed as creating any obligation on his part to <br />issue such orders, and his failure to exercise his right to do so shall <br />not relieve the Contractor from liability for damages to persons or <br />property occurring from or upon the work occasioned by negligence <br />or otherwise, growing out of failure on the part of the Contractor to <br />leave in place sufficient sheeting and bracing to prevent any caving <br />or moving of the ground. <br />4. The Contractor shall construct the cofferdams and sheeting outside <br />the neat lines of the foundation unless indicated otherwise to the <br />extent he deems it desirable for his method of operation. Sheeting <br />shall be plumb and securely braced and tied in position. Sheeting, <br />bracing and cofferdams shall be adequate to withstand all <br />pressures to which the structure will be subjected. Pumping, <br />02220 -2 05 -5564 <br />
