COST ESTIMATES:
1) FUEL - $320/DAYx164 DAYS =
2) LABOR $300 /DAY x 164 DAYS =
3) PIPE $20 x 1200'
4) MAINT. $.10/YD x 136,633
5) LOF $200 x 8
6) DREDGE RENTAL
TOTAL
COST PER YARD
TMoP DREDGE ANALYSIS
PHASE #7 RECLAMATION REQUIRES BACKFILLING WITH SCALPED SAND TO AN ELEVATION
2' ABOVE THE GROUND WATER TABLE. THERE IS A 136,000 SHORTFALL OF BACKFILL MATERIAL
TO MEET THAT REQUIREMENT SO WE WILL BE PUMPING SILT FROM TWO WASHED FINES PONDS
INTO PHASE #7 TO COMPLETE THE BACKFILLING OPERATION. THE COMPANY OWNES A 2000 GPM
SLURRY DREDGE THAT WILL PUMP 20% SOLIDS. THE PRODUCTION CALCULATIONS AND COST
ANALYSIS IS SHOWN BELOW:
OPERATING COSTS PRODUCTION CALCULATIONS
WORK DAY =10 HRS.
% UP TIME = 8 HRS. PER DAY
FUEL REQ. = 80 GAL. PER DAY @ $4.00 /GAL.
= $320 PER DAY
OPER. = $30 PER HR. x 10 HR (INCL FRINGES )
= $300 PER DAY
PIPING = 1200' x $20 PER FT.
= $24,000
LOF = 8 x $200
= $1600
MAINT. = $.15 PER YARD x 136,000 YARDS
= $20,400

PUMP CAPACITY = 2000 GPM @ 20% SOLIDS
PUMP EFFICIENCY = 1750 GPM x 20%
= 350 GAL. SOLIDS/7.5 GAL. /CU.FT.
= 47 CU. FT. / MINUTE
DAILY 8 HR. PROD. = 47 x 60 x 8 / 27
= 830 CU. YDS / DAY
JOB REQ. = 136,326 CU. YDS. / 830
= 164 DAYS / 4 DAYS PER WEEK
= 41 WEEKS
$65 /HR x 8 HRS. /DAY x 164 DAYS = $85,280
THEREFORE, THE RECLAMATION DEFAULT
COST WOULD BE $1.66 / CUBIC YARD
