(RNF) is calculated by adding all entries in block 21c.
Adjusted Removal/Demolition Cost (RDC)
Total RNF is 54.3% (block 22) of the cost to build the
facility new. The total new work cost (NWC) is calculated
= RDCx(1+SAF%)
as follows:
= 8.85 x 1.15 = .18/SF
NWC = $E x Sa x La x CGa x TUa x DCa x RNF
Adjusted New Work Cost (NWC)
NCW = x 1.00 x 0.98 x 1899/1869 x 1.00 x 1.05
= NWCx(1+SAF%)
x 0.54 = .86
= .86 x 1.15 = .90/SF
Step 6. Special adjustment factor (SAF) due to con-
struction limitations must be considered and added.
Total Alteration Cost
Demolition/removal and replacement construction
limitations allowed are as follows:
= Adjusted Removal/Demolition Cost (RDCa)
Dust protection for adjacent work areas
2-7%
+ Adjusted New Work Cost (NWCa)
Limited use of equipment (noise/power)
= .18/SF + .90/SF
limitations
1-6%
= .08/SF
Limited storage of construction materials 1-6%
Protection of completed work
2-6%
Step 7. Determine the facility estimated alteration cost
by multiplying the area of the facility being programmed
Shift work
2-10%
for alteration by the total alteration cost as follows:
Any other adjustment factors must be defined and
justified. Special adjustment factor (SAF) due to
= .08/SF x 40,000/SF
construction limitations can either be applied to the total
unit cost or to the total cost of the project. Using the
= ,563,200
special adjustment factor from (block 25 of the completed
DA Form 7 307-R) the demolition and replacement costs
Step 8. Determine the project cost estimate costs in
are then adjusted as follows:
accordance with step 9 of paragraph 10.
