What is Price Variation?
As per the terms of the contract, amounts
payable / recoverable from the contractor /
vendor consequent to fluctuation in the WPI
(Wholesale Price Index) (inflation / deflation) of
the raw materials used in manufacture of
materials supplied against work award /
purchase order.

Calculation of Ex-Works price when quoted price is inclusive of
Taxes and Duties (10.36 ED;5.5% VAT) (Tax Table)
Ex-Works = Quoted Price to be arrived (Excluding Taxes and Duties)
Excise Duty = 10.36% on Ex-Works
VAT = (Ex-Works + Excise Duty) 5.5%
= (Ex-works+0.1036Ex)0.055
Amount = Ex+0.1036Ex+(Ex+0.1036Ex)0.055

“LA – Lighter Angles” has been substituted with “SBI – Steel Billets”
Consequent to this the IEEMA formula has also been changed.
Care has to be exercised while calculating PV when the project has
commenced before 01-03-2011 and supply has been done after this date
as per PERT.
In such an event calculate “P” using the IEEMA formula shown on the
previous slide up to March 2011. Then substitute the value of “P” so
arrived as “P0” in the formula effective from 01-03-2011.

Conductor and Ground Wire PV formula for ACSR Conductor:
At present the formula will be as per the DWA of the concerned work to be followed:
For example formulae from one of the DWA is as follows:-
P = P0 + K1 (Ar – AO) + K2 (Sr – SO)
For All Aluminum Conductors
P= P0 + ALF (AL-AL0)
For All Aluminum Alloy Conductors
P= P0 + ALF (ALY-ALY0)
For ACSR Conductors
P= P0 +ALF(AL-AL0) + FeF (Fe –Fe0)
PV formula for Ground Wire:
P = (P0 * 0.20) + 0.70(A1/A0) + 0.10(L1/L0)
