1- General Excavating $ 4.50 per cubic yard
2. Compaction 4.50 per cubic yard
3. Import fill/No transportation .50 per cubic yard
Transportation $30 per hour
4. Concrete lining 30.00 per L. F.
5. Grading and shaping 4.50 per cubic yard
6. Imported bedding materials .75 per cubic yard
No transportation
Transportation $30 per hour

We estimate the cost for the concrete lining of the ditch, excluding turnouts
and check structures to be:

1. Construct the new trench for the ditch and fill in existing ditch
with these materials
Area = 16.5 ft2
Length = 58,000 ft.
Volume = 35,500 cu. yds.
Cost = 35,500 cu. yds. x 4.50 c~. yd. = $159,720
2. Fill in remainder of ditch with i~ported material
Volume = 35,000 cu. yds. approximately
Estimated Cost = $5.00 per cu. yd.! x 35,000 cu. yds. = $175,000
3. Compact fill is existing ditch
Volume = 70,000 cu. yds.
Cost = 4.50 x 70,000 cu. yds. =$315,000
4. Precompact new ditch trench as necessary
Volume = 7,000 cu. yds.
Cost = 4.50 per cu. yd. x 7,000 cu. yds. = $31,500
5. Construct ditch lining
Length = 58,000
Cost = 58,000 x $30 per L.F. = $1,740,000

For the check structures we have used the figures the Soil Conservation Service
used in their preliminary engineering report.
