· Drawing E-101 keynote 2 and 3 calls for light fixture type P and PE to be mount at different elevation. Luminaire schedule on drawing E-611 call for the P and PE to me mounted at 13-foot 4-inch AFF. Which is the correct mounting height for the P and PE light fixtures?

Schedule calls “PENDANT, MT 13'-4'' AFF, UIO”. If the room has no keynote the mounting height is what is listed in the schedule. If it has a keynote with a different height, mount to that.

· Drawing E-101 the type V wall mounted light fixture in restroom There no luminaire requirements requirement shown in drawing. Please provide the luminaire for type V light fixture.

Vanity Fixture Basis of Design:

1. HOUSING, FINISH & REFLECTORS - - BRUSHED NICKEL HOUSING WITH SQUARE ACRYLIC DIFFUSER.

3. DRIVER - LED DRIVER TO BE 277 VOLT. FIXTURE TO HAVE A DIGITALLY ADDRESSABLE DRIVER AND/OR LOW VOLTAGE DIGITAL ADDRESSABLE CONTROL DEVICE.

4. CERTIFICATION - UL LISTED FOR DAMP LOCATION SPACE.

5. WARRANTY - PROVIDE A MINIMUM 10-YEAR WARRANTY BY MANUFACTURER.

6. FIXTURE TYPE -TYPE ' V ‘- 1300 LUMENS, 2’ VANITY

· Drawing ES 101 detail B4 is showing a wire gutter to be install on top of the MDP for the service entrance conductors. There six additional feeders for panelboard and transform that must enter the top of the MDP. What size wire gutter is required to accommodate the service entrance conductors and feeders?

Service entrance laterals must be in their own raceway.

· Drawing E-402 key note 8 is calling for providing external power interrupter for under-voltage. The no information provided on the drawings or specification provided for external power interrupter for under-voltage. Please all information required to include manufactures, voltage and amperage for the external power interrupter for under-voltage?

Provide an external power interrupter that meets the requirements of equipment.

· Drawing E-601 electric one line for transformer T-NP3 is showing a 350-line load breaker ahead of the transformer and 150amp on the secondary side of the transformer feeding panelboard NP3B. Is this correct? Or should the 150amp breaker be ahead of the 112.5kva transformer and the 350amp breaker be on the secondary side of the transformer feeding both panelboard NP3A and NP3B?

Refer to NP4C for primary side breaker size. Secondary side is double tapped to feed NP3A and NP3B ECB.

· The light control matrix and the interior lighting specification are not clear on the intent for the lighting control for this project. Are the ceiling mounted vacancy and occupancy sensor line voltage or 24dc?

Refer to control diagram detail A3/E-502. Intent is to have low voltage control wiring from power pack to sensor.

· Can low voltage switches (cat5e) be used instead of the line voltage single pole, 3way and 4-way switches shown on the drawings?

No, Specification 26 51 00 2.5.1 requires line-voltage for toggle switches

· Can low voltage four button on/off raise /low with 0-10v power pack, instead of slide or rotator dimmers?

Provide what is shown on construction drawings.

· Can a detail drawing be provide showing equipment and wiring be provided light controls for each area as per the luminaire control schedule?

Provide design that is compliant with luminaire control schedule.

· Drawing E-401 keynote 6 is call for a light contractor with astronomical time switch. There is not detail showing the number of poles required, amperage of light contractor or if the light contactor is electric held or mechanical held. Or what light fixture are control be the light contractor. Please provided all information for lighting contractor.

Refer to C5/E-611 for lighting contactor schedule. Refer to specification 26 51 00 2.5.4 for lighting contactor requirements.

· There were additional documents added to the solicitation on 08/12, 08/23, and 08/30 but no official amendment. Do these three additions need to be acknowledged on the SF1442 as an amendment?
