99 3/1/22 3/14/22 Specification 23 09 23 o Low temperature protection devices (freeze stats) are not shown on the AHU Schematic.

Are freeze stats required?

o The VAV schematic shows a SA-T before the VAV box.

Supply temperature is measured at each AHU. Can this point be used globally as the supply air temperature to each VAV box, or are individual supply air temperature sensors required at every VAV?

o Are all associated BAS graphics/user views to be updated for any existing equipment serving new terminal units (ex// update all associated VAV and AHU graphics for existing AHU serving new boxes)?

o Specification 22 14 29 2.1.H calls for the sump pump to have a provision of alarm monitoring and BACnet capabilities for the BAS. There is nothing in the plans or specs calling for the controls contractor to communicate with or pick up an alarm from the sump pump(s). Are the sump pumps to be monitored by the BAS? Which points are to be monitored?

o Specification 09 23 3.1.B.1 – 4 Calls for controls wiring to be in conduit. Can controls wiring be ran free air (with appropriate J-Hooks, etc.) above removeable ceilings?

This would provide an installation cost savings.

o Is the DDC contractor to provide a laptop as specified in section 23 09 23 1.1.D.3?

o Can a DDC points list/schedule be provided?

3/4/22 3/14/22 Door #CB27 I cannot find its location on the plan sheets For the other aluminum doors I found these on the plan sheet and there it gave me the frame type to show the elevation for same. Thus I need an elevation view to see if it has sidelites or transom glazing.

I believe you meant to type CB25 as there is no CB27 on the door schedule and drawings. Door CB25 is not required on this project.
