1. 7/19/22 7/20/22 I did not see a lay-out for the fire detection and alarm or a physical access and security. Did I miss something or is there a lay-out coming for my vendors to bid off of?

Fire alarm: Refer to electrical drawings and division 28 specification section for specific information. In general, electrical enlarged plans show new fire alarm devices to include detection in each telecommunication room (TR).

Access control/ security: Refer to telecom drawings and division 27 and 28 specification sections for specific information. In general, dual authentication card readers are shown outside of each TR on the individual floor plans, access control panels and power supplies, as well as video surveillance cameras are shown in the TR room enlargements.

2. 7/19/22 7/20/22 There is no controls specification section (23 09 23) there is, however, a section about DDC trending in 01 91 00(3.5) so it seems that at least the following points need to be in the DDC system:

1. Space temperature

2. Supply air temperature

3. Space Humidity

4. Water Sensor

5. DX cooling enable

6. Split system on/off

Yes, all these points need to be included. In addition, see Split System Sequence of Operation on M201.

3. 7/19/22 7/20/22 It also needs to be indicated who and how these points are to be obtained. It needs to be very clear if the units need to come with all of these points or if they will need to be provided by the DDC contractor. Currently the 23 81 43 only calls for the unit to come with a BacNet controller that shows points and refers to the non-existent 23 09 23 section so they wouldn’t know what points need to be provided.

It is up to the bidding contractor to decide who will provide these points, typically this is done by the controls contractor.

12. 7/19/22 7/20/22 Sheet B409-EP300 & B410-300 say to take the feeds for the ATS to B424. I know B411 has a generator next to it.

Are the feeds supposed to go to b411 instead of B424?

Building 411 generator is not large enough to support the loads for 409 and 410. We need to feed as shown
