PROJECT #564-14-124
Install Catwalks for Boiler Access and Maintenance
Fayetteville, AR
A/E:MillerRemick LLC
Building Two – 2nd Floor

1010 Kings Highway South Cherry Hill, NJ 08034

DATE: February 26, 2021

ITEM 1 – Bidding Requests For Information

#
Reference
Question
Answer
1.
GC101
On sheet GC101 it shows an 800A breaker added in MDP-9 to feed a temporary 300KVA transformer that then feeds to the new boiler trailers. I’m guessing the 300KVA transformer is supposed to step up voltage to 480V but no specs are given for this transformer. Please provide specs for 300KVA transformer.
The transformer feeds the temporary boiler lineup. This is a step-up transformer with the primary on the transformer at 208-volt, 3-phase and the secondary of the transformer at 480-volt, 3-phase.
2.
GC101
On sheet GC101 the electrical feed to the temporary boiler trailers is shown to be (1) 3” conduit with (4) #350 and (1) #4. This conduit runs overhead to the boiler trailers and then splits to go to both trailers. This leads me to a couple questions. How is this feed supposed to split and catch both trailers, no junction box or splice point is shown. The only overcurrent protection shown on this feed is the 800A breaker in MDP-9, are fused disconnects going to be provided with the boiler trailers?
Boiler trailers will be fed from a distribution panel. Refer to updated drawing E-601 for additional information on the temporary power distribution system.
3.
Page 17 S-502

If a WT6 beam falls in location of a current rivet, does the WT6 Beam section get notched out to clear a rivet?
The WT6 can be notched around a rivet. See #4 above for more information.
