SUMMARY OF CHANGES

(End of Summary of Changes)

Attachment #1

Please see answers below. Sheet S-501 and C-502 are below the Questions portion of this attachment.

1) Security fence. If the concrete façade option is awarded, it sounds like the Government will have to remove the existing fence and a new fence (that will be constructed differently) will need to be installed.

Answer: See amended sheet C-502, callout in quadrant K17.

2) Instruments and electrical. Will you be reinstalling/replacing instrumentation along the tunnel wall?

Answer: See Amended sheet C-502, callout on quadrant J14 and note 2.

3) Door. If just the base work is awarded, it doesn’t sound like we need to replace the door? But if the concrete façade option is awarded, we will need to include a new, smaller door?

Answer: See amended sheet C-502, note 4.

4) As discussed at the pre-bid meeting, will alternate designs be entertained for the tunnel adit repairs as currently depicted on the contract drawings.

Response: See specifications section 31 68 13 paragraph 1.1.2.a.
