CORROSION PROTECTION
The Bidder/Contractor shall bear the responsibility for all losses and damages, which may, occur
through inadequate measures against such influences and shall replace the damaged parts at his
cost.
The Bidder/Contractor shall bear the full responsibility for galvanizing and paint applied by him
or by others.
The complete painting and corrosion protection system is guaranteed for a period of not less than
5 years after the Final Acceptance Certificate.
The Bidder/Contractor shall provide a Guarantee Performance Bond to assure the performance of
extended guarantee obligations for corrosion protection. The Bidder/Contractor (after FAC) shall
carry out during the extended guarantee period any repair or replacement on the corrosion
protection executed under this specification at no additional cost after being intimated by
ADWEA/ADDC/AADC.
If the repairs are not carried out to the satisfaction of ADWEA/ADDC/AADC, these repairs shall
be performed by others, who will be assigned by ADWEA/ADDC/AADC, and the costs thereof
shall be borne by activating the Performance Bond valid for the extended guarantee obligations.

SAFETY PRECAUTIONS
All painting and corrosion protection works shall be performed under strict safety conditions,
primarily adequate ventilation and protection from open flames, spark and excessive heat.
The Bidder/Contractor shall take all necessary precautions to protect personnel and property
from hazards due to falls, injuries, toxic fumes, fires, explosions or other dangers.
All paint and thinners shall be stored in areas, which are well ventilated and protected. The
Bidder/Contractor shall consider air-conditioned storage facilities due to the limited store-ability
of the paints required.
Temporary constructions, ladders scaffolding, runways, etc. required for safe execution of the
painting work shall be rigidly built so as to safely support four times the weight of all materials,
apparatus, equipment and workers thereon.
Test Instruments
The surface preparations for steel iron works shall be compared with the relevant pictures of SIS
05 5900. The surface profile shall be measured by using a Profilometer, i.e. Tester Tape.
If required by ADWEA/ADDC/AADC/ENGINEER copper sulfate test shall be carried out to
check for residual mill scales.
The dry film thickness or galvanization thickness on steel shall be measured by means of a
magnetic or electrical thickness gauge such as "Microtester" or "Elcometer", and recorded in a
tabulated form, indicating each layer of coat and the total dry film thickness.
In case of fluid retaining structures, pinhole detection shall be carried out by means of lowvoltage, non-destructive flow detector, whereas, in the case of rubber lining or wrapping,
damages shall be checked by means of a spark tester.
