QUESTIONS/RESPONSES

1. Subcontractor Question

Per drawing E-002 #12.2.1 All visual devices shall remain synchronized throughout the project. Can all smoke detectors related to the 3rd floor ceiling be removed for construction or will they need maintained protection during the construction process?

FRA Response

Smoke detection can be removed during construction as the 3rd floor is also sprinklered. Notification devices most likely will need to stay in place. The Fire Techs will need to be called to make this disablement.

Please give them ample notice so they have time to remove devices if need be.

Will FNAL fire techs assist with the fire alarm panel if the devices are to be temporarily taken out of service?

See response to question #1.

Will the cubicles be removed/relocated for the construction project? If so, who is responsible for moving and disconnecting the cubicles?

Yes, to both.
