The project site has 3 cooling towers of 215 ton capacity each. These cooling towers serve the HVAC system of the building and are operational for 8-10 hrs on all working days. These cooling towers support automatic bleed-off and meet the credit requirements.

There are 3 small cooling towers of 40 ton capacity each. These are temorary use CT's which are only operational when DG sets are run for power back-up (3-4 hrs/day in peak requirement). Also these cooling towers only serve the DG sets and no other part of the building.

Are the mechanical services cooling towers also to be included in the credit documentation? There is no clarification on this situation in the reference manual. A way forward will be highly appreciated.

Thanks
