Under 084413, 3.5(A), the specification reads, "Testing Agency: Engage a qualified testing agency to perform tests and inspections". Since the same tests are required under each of these specification sections, it would seem that the same testing agency would handle all of this testing.

159. Question: This question is in regards to the metal shelving that is found inside of the wire mesh cages. Drawing A‐554, details D2 and D3 of this shelving is what I see in every one of the

Readiness and Reserve Center projects that bid. With the number of shelves, spacing requirements, side and back sway braces for an open shelving unit as shown in the details.

However, when you go to the specifications for this shelving; Section 105613, Specifically, page

4, paragraphs 2.2, Lines 4, 5 and 6. Line 4 is for the sway/cross bracing that the drawing elevations show. But lines 5 and 6, call out for the backs and end panels to have closed panels on them. Which is the opposite of using the sway braces. Which item is required? Sway/cross braces for open units or closed backs and sides panels?

Answer: End panel and back panel per article 2.2.A.5 and 2.2.A.6 are not required. See

Amendment 0004, Section 105613.

160. Question: Same spec Section 105613, specifically, page 4, paragraphs 2.2, Lines 14, items A and

B. A is the same closed end panel I asked about above, but Line B asks for shelf label holders.

Are the shelf label holders needed? They are not shown on the shelving elevations of A‐554 details D2 and D3, and I’ve never seen them on any one of the previous Readiness or Reserve

Center project before.

Answer: Article 2.2.A.14.a is not required. Article 2.2.A.14.b is required. See Amendment 0004, Section 105613

161. Question: I noticed on sheet G‐101 note 2 & 5 show that the structural steel on this drawing will have a 0 hr. rating, but there are specs for the fireproofing with SFRM and Intumescent paint. Let me know what hourly rating you would like these both to have (ie. 1 or 2hr). See the attached table 601.

Answer: The intumescent paint is for the purpose of a thermal barrier over exposed foam insulation.

Drawing G‐101, general note 1 states that the Life Safety Plan is supplemented by a fire protection and life safety report. The building is of construction type IIB and IBC Chapter 6 does not require a fire rating on various elements of the building. However, per both Drawing G‐101 and the report, the project is under the North Carolina Building Code, which is stricter than the

2009 IBC in terms of occupancy separation as explained.

Drawings G‐104 and G‐105 clearly poche’ areas of the second floor where a fire separation is required between the S‐1 occupancy on the first floor and the B occupancy on the second floor.

The boxed and shadowed notes explain the extent of the fire protection on the elements supporting the second floor in the areas of poche’.
