For walling pieces round timber shall not be allowed. In a vertical plane, there shall<br />
be at least three struts or more as directed by the Engineer. They shall rest on<br />
walling pieces. The spacing of the struts shall be as per the requirement of the<br />
design. At the bottom, extra struts shall have to be provided if ordered by the<br />
Engineer. The rates for excavation do not include the cost of shoring, which shall<br />
be paid for separately as per relevant item of the bill of quantities. The contractors<br />
shall be held responsible for providing secure shoring, and for adopting every other<br />
precaution, which may be necessary for protecting nearby structures, which are<br />
likely to be damaged as a result of excavation. The contractors shall design the<br />
shoring required for actual site conditions and shall provide shoring accordingly.<br />
The design shall be submitted to the Engineer on demand. The shoring shall be so<br />
designed that lowering of pipe of normal length or any other pipe laying operation<br />
does not necessitate the removal of any strut or any other member of shoring. If the<br />
Engineer requires the adoption of any special measures or precautions, the<br />
contractor will comply with the same immediately. If any part of a nearby structure<br />
is cut out or removed for facility of work, the same shall be made good on<br />
completion of the work by the contractors at their cost.<br />
In the event of the contractors not complying with the provisions of this contract in<br />
respect of shoring the <strong>Engineering</strong> may, with or without notice to the contractors,<br />
put up shoring or improve shoring already put up or adopt such other measures as<br />
he may deem necessary, the cost of which shall be recovered from the contractors.<br />
Such action on the part of the Engineer, shall not, however absolve the contractors<br />
of their responsibilities under this contract.<br />
No part of the shoring shall, at any time, be removed by the contractors without<br />
obtaining permission from the Engineer. While taking out shoring planks, the<br />
hollows formed shall be simultaneously filled in with soft earth and shall be well<br />
compacted as directed.<br />
