Substation L1/ MCC L1 Update #2

July ??,2012

Status of Procurement Substation

All approval drawings submitted Testing is expected to take place August 8-10 Delivery will occur soon after testing is completed

MCC All approval drawings submitted Expected arrival date of Mid to Late August (55-75 working days

after approval drawings reach factory floor) Drawings approved on 5/30/2012

Cable All cable delivered Stored in LINAC 350 MCM will be stored at warehouse until installation is closer

Panelboard Delivered Needs to be assembled

Status of Procurement (Cont.) Safety Switches

Delivered Stored in LINAC

Cable Supports Delivered Stored in LINAC

Support Structures Will be built out of unistrut Assembly has not yet begun Support frames will be built in house

Junction Box Drawing is complete Fabrication companies have yet to respond

Since only one needs to be ordered it is unlikely that a company will construct this enclosure

Will be submitting the drawing to the machine shop soon

Project Schedule Currently at a stand still

Complexity Safety issues

Install should still be okay for originally planned September install

General Cleanup 2-3 weeks prior to shutdown of substation Temporary electrical power will be setup the weekend prior It could take riggers several days to remove and install

substations Small clearances Large weights May be several more days if given okay to shore the floor

Issues Substantial Weight Increase

10,500 lbs. vs. 17,700 lbs. Gallery floor has a very low load limit (350 lbs./sq. ft.)

This could effect everyday operations Fork lifts, Tour groups, Removing equipment from downstairs

Could be wrong Stevenson has no suitable indoor crane

Ceiling height is too low for carrydeck crane 55,000 lbs.

Shoring the floor may not be a possibility Much of the transformer will need to be dismantled

Secondary bus bars, frame, sheet metal Increases electrician time

Suggestions FESS has been notified that it needs to begin looking into

ways to fix this issue Cut a hole in the ceiling

Has been done at other sites around the lab Install outside

Requires Federal to make outdoor gear Engineering Expense Siemens subcontract issue

Expensive cable runs Rigging job would be simplified Aesthetics committee

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 be locked out and tagged out Group lockbox 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)

Unknown Cost Will remain unknown until a plan is put in place by FESS

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 riggingPrevious Estimate: $23,000 -> excluding rigging

Increase can be attributed to increased electrician time and panelboard cost

Commissioning Visual Inspection Hi-Pot Disconnect panel boards from temporary power Reconnect panel boards DHP-L1-1 will be turned on first

Fire alarms Lighting Etc.

DHP-L1-2 DHP-L1-3

What Will Become of the Removed Equipment? Transformer will be kept as a spare

Currently have 1 spare for 8 transformers (5 – high rise, 3 – LINAC)

Transformer will be examined to make sure it is in good working order

Will be stored in Booster parking lot Will be placed on a truck the same day it is removed to avoid

excess rigger fees Breakers

Will be rebuilt and tested Used as spares

Primary Switch Will be rebuilt and tested Used as a spare
