AMENDMENT 002

QUESTION: (Refer to Draw. A-07- Door Schedule) Exterior Mechanical Room Door #16 & Entrance Door to Corridor #15 call for fiberglass reinforced doors. The provided specifications (Sect. 08 16 13) are typical for only one (1) manufacturer in the USA (CHEM-PRUF Door Co.). These doors are extremely expensive (pure cost without installation or hardware), and have an 8-10 weeks fabrication time plus 2 weeks of in-land freight for a 10- 12 week delivery schedule (refer to attached quote for specifics). Will the government provide any option or will sustain its spec?

ANSWER: The government wants the doors to meet the saline features of the fiberglass reinforced doors (FRP) doors as indicated in the specifications.

QUESTION: (Refer to Draw. A-07- Door Schedule) schedule calls for metal frame for door #15. Fiberglass Reinforced Doors are not compatible with metal frames. Can we presume it should be a Fiberglass compatible frame?

ANSWER: Yes, the FRP doors shall have a solid FRP door frame.

QUESTION: (Refer to Draw. A-07), the head jamb & sills detail should be revised. Most do not match the doors presented on the Door Schedule.

ANSWER: Drawings (M1821-D) A-07, sheet 10 has been revised and attached.

QUESTION: (Section 26 20 00), this specification establishes that all conductors #10 AWG and smaller shall be solid. It is our understanding that this building will not have radio communication equipment or cause any interference. Could stranded #12 & #10 THHN wire be utilized for receptacles and lighting? Solid wiring is very difficult to obtain and costly. Installation of solid wiring is also costly. Could this be considered for government revision?

ANSWER: No, Please bid in accordance with the specifications.

QUESTION: (Section 08 16 13, “Fiberglass Reinforced Door & Door Frame Systems”). Under this title there are two specs: Sub-paragraph 2.1.1 mention Non-rated Fiberglass Reinforced Plastic and the sub-paragraph 2.2.2 Fire- Rated Fiberglass Reinforced Plastic. Which of the two will govern for the Fiberglass Door system?

ANSWER: The FRP Doors are Non-rated

QUESTION: (Section 08 71 00 “Door Hardware”) Sub-paragraph 3.5 there is not a hardware description for the door Mkd 11, type “E” for room 114.

QUESTION: (Sheet E-01 Note 10) Is the existing 37.5 KVA transformer to be removed and disposed a dry type transformer?

ANSWER: Yes, the existing 37.5 KVA transformer is a Dry Type Transformer.

QUESTION: (Sheet E-02) Shows (21) light fixtures for circuit A-31 and (24) light fixtures for A-29. This is (45) fixtures on two (2) circuits. We understand that they should be distributed in 4-5 circuits instead of 2. Please confirm.

ANSWER: Yes, Circuit A-31 has 21 light fixtures connected to it, (65W x 21 = 1365W on a 20 Amp Circuit.

OK). Circuit A-29 has 24 light fixture connected to it, (65W x 24 = 1536W on a 20 Amp Circuit. OK). T-8 bulbs are 32W ea. This is not a residential application where you have 1 point for every light fixture for a total of 12 points per circuit.

QUESTION: Please confirm the use of 35w LPS wall packs Type A as described on E-06 (Sheet 27 of 27) Light Fixture schedule in the three closets indicated on the Lighting Plan E-02 (Sheet 23 of 26). This type of lighting luminary is usually specified for exterior use for general illumination.

ANSWER: The light specified for the closet is a Type "C" (not a Type "A" as asked), the answer is yes, and is a 35W LPS Fixture with the saline features specified on Drawing E-06.

QUESTION: Description of surgical lamp on sheet E-02 with reference on note 4 to sheet A-06 not specified on Lamps schedule please clarify?

ANSWER: Keynotes 6, 7 and 8 on Sheet E-3 shall read as follows:

6. New 37.5 KVA, 3 phase, 480V primary, 208/120V Secondary, Delta-Y, Dry type transformer in Nema 4X and S.S. enclosure.

7. New 2P, 60A Nema 4X Disconnect Switch in S.S. enclosure, with 60A fuse (see riser diagram).

8. New 2P, 200A Nema 4X Disconnect Switch in S.S. enclosure, with 200A fuse (see riser diagram).

QUESTION: In difference of other plans these doesn't specify if the circuits and receptacles show on drawing E-03, if all the receptacles on this page are going to be new and if the conduits are going to be installed on the surface or inside the concrete. Please clarify.

ANSWER: All electrical equipments (receptacle, light switches etc) will be new. Conduits and junction boxes for receptacles are going to be installed between the drywall and the concrete walls.
