4.2.7 Galvanizing
4.3.0 Tolerance
4.4.0 Acceptance
All galvanizing shall be uniform and of standard quality when tested in
accordance with IS:2633 - Method for testing uniformity of coating on
Zinc Coated Articles and IS:4759 - specification for Hot-Dip Zinc Coatings
on Structural Steel & other allied products.
The tolerances on the dimensions of individual rolled steel components
shall be as specified in IS:1852 - specification for rolling and Cutting
Tolerances for Hot-rolled Steel Products. The tolerances on straightness,
length etc. of various fabricated components (such as beams and girders,
columns, crane gantry girder etc.) of the steel structures other than steel
railway & road bridges, structures subjected to dynamic loading (like wind,
seismic etc.) and thin walled construction (like box girders) shall be as
specified in IS:7215 - Tolerances for Fabrication of Steel Structures.
Should any structure or part of a structure be found not to comply with any
of the provisions of this Specification, the same shall be liable to rejection.
No structure or part of the structure, once rejected, shall be offered again
for test, except in cases where the Engineer considers the defects
rectifiable. The Engineer may, at his discretion, check the test results
obtained at the Contractor's works by independent tests at an approved
laboratory and should the items, so tested, be found to be unsatisfactory.
When all tests to be performed in the Contractor's shop under the terms of
this contract have been successfully carried out, the steelwork will be
accepted forthwith and the Engineer will issue an acceptance certificate,
upon receipt of which, the items will be shop painted, packed and
despatched. No item to be delivered unless an acceptance certificate for the
same has been issued. The satisfactory completion of these tests or the
issue of the certificates shall not bind the Owner to accept the work,
should it, on further tests before or after erection, be found not in
compliance with the Contract.
4.5.0 Delivery of materials
4.5.1 General
The Contractor will deliver the fabricated structural steel materials to site
with all necessary field connection materials in such sequence as will
permit the most efficient and economical performance of the erection work.
