Exhibit G-E1.0 Preliminary Earthwork AnalysisNote 1: For construction, equipment combinatations other than those shown could be configured. Information shown below is for cost estimate purposes only.
Note 3: Instead of D9 dozers, D6 dozers may be preferable because of maneuverability. Assuming D9 dozers is conservative.
Note 4: For Types 3 and 4, larger excavators or shovels could be feasible.
Note 5: Crews and productivities based on conversations with contractors, index values in the 2008 equipment library, RS Means cost data, equipment manufacturer's data, and unit price data

Job Condition Description
A Easy Digging (unpacked earth, sand, gravel, ditch cleaning etc.) Digging to less than 40% of machine's maximum depth capability.
Swing angle less than 30°. Dump onto spoil pile or truck in excavation. No obstructions. Good operator.
B Medium digging (packed earth, tough dry clay, soil with less than 25% rock content). Depth to 50% of machine's maximum capability.
Swing angle to 60°. Large dump target. Few obstructions
C Medium to hard digging (hard packed soil with up to 50% rock content). Depth to 70% of machine's maximum capability.
Swing angle to 90°. Loading trucks with truck spotted close to excavator.
D Hard digging (shot rock or tough soil with up to 75% rock content). Depth to 90% of machine's maximum capability.
Swing angle to 120°. Shored trench. Small dump target. Working over pipe crew
E Toughest digging (sandstone, caliche, shale, certain limestones, hard frost). Over 90% of machine's maximum depth capability.
Swing over 120°. Loading bucket in man box. Dump into small target requiring maximum excavator reach. People and obstructions in the work area.

Cycle time cycles/hour
Operator Skill/Efficiency 0.95 (95%) (1) downtime of 30min every 10hrs
Machine Availability 0.95 (95%) (1) downtime of 30min every 10hrs
Gen Operational Efficiency 0.80 (48 min/hr) (1) equivalent downtime of 120min every 10hrs
Effective Cycles per Hour 142 (cycles/hr) (1) total equivalent downtime of 3hr every 10hrs;
p. 4-192 (2) effective cycle above max. for Job Condition B
Step 4 Calculate Required Bucket Capacity
Nominal Bucket Size 5 cy
Fill Factor 80 %
Bucket Payload Volume= Nominal Bucket Size x Fill Factor
Bucket Payload Volume= 4 cy
Material Density / Loose= 2700 lb/cy
Required Payload = Bucket Payload Volume x Material Density/Loose
Required Payload = 10,800 lb
Effective Cycles per Hour= 142 cycles/hr
Step 5 Calculate Production
Hourly Production Required= Required Payload x Effective Cycles per hour
Hourly Production Required= 1,538,157 lbs/hr 769 tons/hr
570 LCY/hr
495 BCY/hr
Crew: 1 Hydraulic Excavator (crawler)
1 Dozer (crawler) to maintain load/unload area
Assume excavator, trucks can operate on Type 3 material to excavate the Type 4
