The Contractor shall be responsible for and shall pay for any alterations of<br />

the work due to any discrepancies, errors or omissions on the drawings or<br />

other particulars supplied by him, whether such drawings or other particulars<br />

have been duly approved or not in accordance with the Contract.<br />

3.0.0 WORKMANSHIP<br />

3.1.0 Fabrication<br />

3.1.1 General<br />

All workmanship shall be equal to the best practice in modern structural<br />

shops, and shall conform to the provisions of the Indian Standard IS:800 -<br />

Code of Practice for use of Structural Steel in General Building<br />

Construction and other relevant Indian Standards.<br />

3.1.2 Straightening Material<br />

3.1.3 Cutting<br />

Rolled materials before being laid off or worked, must be clean, free<br />

from sharp kinks, bends or twists and straight within the tolerances<br />

allowed by the Indian Standard Specification IS:1852 - Specification for<br />

rolling and cutting tolerance for hot-rolled steel products. If straightening is<br />

necessary, it may be done by mechanical means or by the application of<br />

a limited amount of localized heat. The temperature of heated areas, as<br />

measured by approved methods, shall not exceed 600 Deg. C.<br />

Cutting shall be effected by shearing, cropping or sawing. Use of a<br />

mechanically controlled gas cutting torch may be permitted for mild<br />

steel only. Gas cutting of high tensile steel may also be permitted provided<br />

special care is taken to leave sufficient metal to be removed by machining,<br />

so that all metal that has been hardened by flame is removed. Gas cutting<br />

without a mechanically controlled torch may be permitted if special care is<br />

taken and done under expert hand, subject to the approval of the Engineer.<br />
