Notes: The following notes (a to j) explain in detail the intention of various terms in qualifying
requirements:
a) Earth dams, ash dykes, and reservoir embankments, which are designed as water retaining structures, shall
be qualified for this work. However, canal embankments, guide bunds along water courses shall be

railway embankments, site levelling works etc. shall not be qualified.
b) Sand / substitute filter media as filter either in chimney or in blanket or both; used in embankment shall be
considered in earthwork quantity calculations. Rock toe shall not be considered.
c) For embankments/reservoir/dyke, the height and quantities shall be considered above formation level upto
dyke top for qualifying requirements purpose. However, in case of ash dyke raising works, for both
inward/upstream & outward/centre line methods, the height of dyke shall be considered from the stripped
level of ash inside the lagoon for qualifying requirement purpose.
Formation level means bottom of stripped level for the dyke formation. The earth work in cut off trench
(COT) shall be included for quantity estimation for qualifying requirement under clause 1.2. However, the
depth of COT shall not be considered for the height calculation for qualifying requirement under clause 1.1.
d) Wherever the ash dykes and other embankments are constructed in different contracts, the height
applicable to individual contract only and not the cumulative effect shall be considered for the purpose of
determining compliance of clause 1.1. For example where the contract is for raising an embankment, only
the raising portion shall be considered and not the earlier starter dyke.
e) The word “executed” means the Bidder should have achieved the criteria specified in the qualifying
requirements within the preceding seven (7) year period even if the contract has been started earlier and /or is
not completed / closed.
f) In clause 1.1 above, Bidder should have constructed entire qualifying height of embankment work

quantities can be claimed by the bidder in the ratio of bidder’s share in the integrated Joint Venture
Agreement, provided the bidder establishes that it regularly undertakes works as at Clause 1.2 above. The
