Hi all,
I need for the group to check my premise for this calcuation.
The problem: I need to adjust a DPW budget to Year 2005 dollars in No.CAL.
My approach: Study/extrapolate available historical cost data for my vicinity/locality in order to determine the differential changes in cost--I have found a private group (RS Means) that can furnish that for a small fee;
thence, knowing the difference,a reasonable interest rate may be calcualated; thence, apply a PW-to-FW formula taken from an interest table (i,n,PW/FW)
NOTE: due to the 'gas' shortage/911/materials cost increases, etc., I've noticed a spike in availabe cost data curve for the last 4 yrs, say. Any recommendations on making adjustments to the data/curve, intergrating that data as-is, or ignoring that, or parts, of that data?
Thanks in advance for helping to all.
