SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been added by full text:

REQUEST FOR INFORMATION

1. What are the specifications for the limit switches that will be required.

Answer: The limit switches shall be those of a make and model that are compatible with the Programmable Logic Controller (PLC).

2. Will aluminum conduit be an approved equal to stainless steel conduit?

Answer: Conduit shall be stainless steel. Aluminum will not be approved.

3. Will the existing operators be able to be temporarily energized electronically so the existing conduit can be removed leaving space for the new conduit?

Answer: Disconnecting the electrical connection should be done in a manner to minimize down time for the operators. Portable actuators (drills) are available to serve as backup to move operators while the power is disconnected.

4. Do you have examples of vandal proof lighting you would like to see used?

Answer: Vandal proof lighting shall have the following characteristics:

1. All metal wire guard

2. Minimum of 7 GA steel round wire

3. Screw eyes for mounting

4. Material shall be stainless steel

5. The specifications talk about operating at six inches per minute, is this assumed to be done via variable frequency drives, or gearing? And will speeds vary?

Answer: The current operators utilize gearing. The minimum speed that will deemed to be acceptable is six inches per minute. Speeds may be increased to more than six inches per minute with the new operators, but may not be lower than six inches per minute.

6. The lead time from a local manufacturer is 10 weeks for the operators. Can the Period of Performace be extended to account for the manufacturer lead time?

Answer: The Period of Performance has been revised in the Statement of Work from 90 days after Notice to

Proceed to 120 days from Notice to Proceed.
