Temporary Power Plan “Siphon” power from panel DHP-L2-2 Circuit #1 Cable will be run on temporary supports

4 conductor 350 mcm cable is heavy (~7 lbs./ft.) and will need an open area to lay

Some cable will be put on the floor but will be covered by a cable bridge

Setup 2 temporary panel board(s) Run cable to individual loads

DHP panels, MCC loads DHP panels will have potential

hazards removed (mains, MCC, etc.)

13.8 kV lines will be disconnected MCC loads will have configuration

control locks We will check current prior to using

any MCC loads to ensure they will not trip off during operation

Power will be provided 24 hours a day

Installation Costs 1 Crew of Riggers (4-6 men)

Could be as much as $30k Will remain unknown until a finalized roof plan is put in place

2 Week of Electricians $100/manhour x 2 electricians x 80 hours = $16,000

Cable 2/0 - $3,500 2 – $3,700

House Power $4,200 for panelboard

$2,000 for assembly Miscellaneous Stock purchases

$2,100

Total Cost : $31,500 -> excluding rigging and roofPrevious Estimate: $23,000 -> excluding rigging and roof

Increase can be attributed to increased electrician time and panelboard cost
