Question
Question
sir, my question relates to the following.

Formula for Escalation- Labour component
V1 = 0.85 P K1/100 *(L1-L0)/L0

Where, V1 = Amount of price variation,
P    = Cost of work done during the period,
K1  = Percentage of labour component in the project cost,
L0   = Basic consumer price index,
L1   = Average consumer price index
Formula for material component shall be similar as above with appropriate changes to the material specific.
Q1. Why 0.85 of P is taken.
Q2. In case, while estimating any work contractors profit restricted to 7.5 % instead of 15 %. Is the formula changes to 0.925 0f P.
