50 Ready FP In the specification section 283111 DIGITAL, ADDRESSABLE FIRE ALARM SYSTEM, there are two sections I needed some clarification on. “1.7 Quality Assurance, B.

Fire Alarm demolition and installation shall be performed by a fire alarm technician” and “1.9 Sequencing and Scheduling C. …Fire alarm system demolition shall be performed by a fire alarm technician.” I am assuming this means device termination/removal and that any conduit or disconnect fire alarm cabling could be removed by the Electrical Contractor. This is important for us because we do not install/demo conduit especially on projects of this size, usually the Electrical

Contractor will remove/install any conduit and many times they install/remove the cabling as well and we come back to make the final terminations of devices & equipment.

Removal/installation of fire alarm conduit system and boxes shall be performed by electrical contractor. Removal/installation of fire alarm cabling, devices, and termination and testing shall be performed by fire alarm technician.

TAL

54 Open G Although the specification say “all demo to be done during the hours of 6:00PM-

6:00AM” will we be allowed to work on demolition during normal business hours if we are not making excessive noise?

Only demolition work that creates excessive noise is to be conducted outside of normal business hours. If any work results in occupant complaints it is to be stopped immediately and resumed after business hours.

84 Open E Note #7, on electrical drawing ED100, states to remove and replace the MCC. But there isn’t an MCC listed on the one-line on sheet EP602. Are we to completely replace, or Retrofill? Is this MCC fed from the SMF Data Center Gear? And if we are to replace this MCC is there any information for this MCC? Such as switch count, AIC rating, and amp rating of each switch, etc?

Remove the MCC. FSB

85 Ready E Is it the intent on this project for the electrical contractor to perform any work on the fire alarm system?

The electrical contractor is only to provide the rough-in for the fire alarm system.

FAA

86 Ready FAA Will the FAA IT group provide their own faceplates and data jacks for their cables? Yes FAA

87 Ready E In the general note “A” on the Data/Telecom prints, sheet AMP-400-E-TT101, it states that all offices will get three cables for each work outlet. Does this include the floor boxes, in the modular flooring?

Yes. FAA

88 Open E Will the electrical contractor be required to install wall sleeves for conduit when penetrating gypsum fire rated/non-fire rated walls? Or will the use of fire proof caulking around conduits be sufficient?

Any UL listed assembly is acceptable.

89 Open E Will there be any additional grounding required for the low profile flooring, other than manufacturers recommendations?

Grounding shall be in accordance with manufacturer's recommendations and any applicable codes and standards.

91 Open E Will we need to maintain the redundant feed to the MSB switchgear, for the temporary service, during construction of phase 1?

Maintain redundant feed to MSB switchgear

92 Open E Are the electrical rooms considered mechanical areas? For the purposes of conduit selection, yes. See response to question 51.

93 Open E On the lighting detail sheet AMP-400-E-EL501, shows the detail for the typical power pack occupancy sensor set up. But, in the general notes, “B” states that emergency lights that function as night lights are to be on 24/7. Lights that are not identified “NL” shall be switched with the room lights. Since the emergency lights and the normal power lighting cannot be in the same raceway, they would need their own switch and power pack. They do make power packs that have two sets of contacts in them, but they are more expensive, and would still need the additional separate switch to operate according to the diagram. What is the intent on switching two different circuits that cannot share raceways, from the same switch?

Design intent is for one low voltage switch to control multiple contactors for an area. The emergency lighting circuit shall be switched via power pack with a fail safe (ON/closed) configuration.

94 Open E Who will be inspecting the elecrical work? Verify with the FAA.

95 Ready E Spec section 260523, part 3.1, paragraph A, #1, states that outlet boxes shall be no smaller than 4” wide, 4” high, and 2-½” deep. 2-½” isn’t a standard box size for boxes. Should it say 2-1/8”?

2 1/8 is correct FAA

96 Open E Is it the intention to utilize the warning planks called for in specification 260543 paragraph K?

Omit 3.4 (K) from 260543.

97 Open E Is it the intention to label all conduits, exposed or concealed, as indicated in

260553-2, part 22, paragraph B? And if so, what is the distance between markings?

And which means will be enforced?

Markings shall occur at the beginning and end of each conduit run, as well as on entry/exit of penetrations and junction boxes.

98 Open E Can the Retrofill of the existing GE gear, be done by other manufacturers, if the

Retrofilled gear performs within intended use, and the proper arc flash study, coordination study, and short circuit

Alternatives to GE shall be permitted, provided they do not require more outage time, have the same warranty, are UL listed, and are otherwise equivalent.
