SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE (SF 30)

The following have been added by full text:

AMENDMENT 0004 Q&A

Question 1: The specification includes a shielded cable spec but the drawings do not call out any shielded cables.

Will any of the cables be required to be shielded?

No, there are no shielded cables.

Question 2: The specification calls out NEMA 4 cast iron bossed and tapped enclosures for the switchyard equipment junction boxes but the drawing shows NMEA 3x. Will the government actually require cast iron boxes in the switch yard or will stamped steel with watertight conduit hubs be sufficient?

Both type of pull boxes will be accepted by Government.

Question 3: The specification calls for the vault enclosures to the NEMA 3R but the drawings show them to be 4X.

Which is the preferred rating for the vault enclosures 3R or 4X?

The vault enclosures shall be NEMA 4X

Question 4: The specification calls for the cable tray material to be 316 stainless steel but the coating to be hot dill galvanized after fabrication. After checking with several manufactures this is not an option they offer so is this specification correct or should the tray just be standard hot dill galvanized after fabrication?

Cable trays shall be hot dip galvanized.

Question 5: The demo drawings show the existing switchyard lighting conduits coming out. Does the government expect to us to refeed the existing lights or install new lights? If the government wants new lights please provide a specification.

Existing lights shall be reused.
