F. Questions/Comments:

1. Several questions were asked:

a. Question: Will the contractor have access to the entire building at once?

Response: No. The area encompassed by a single phase will be emptied of stored product while work is occurring for that phase. After a phase is completed, product will be moved back into the area of the previous phase, and the area encompassed by the next phase will be emptied of product.

b. Question: Will the contractor be responsible for rough cleaning and final cleaning of the entire building?

Response: The contractor shall be responsible for all cleanup related to the contractor’s work. This includes cleanup of any water that discharges from existing or new piping, regardless of what area(s) of the building it runs to.

c. Question: When will bidders know if any alternates have been taken?

Response: This will be decided after bid opening when the bids have been reviewed, and will be made known at the Time of Award.

(7)

d. Question: A request was made for more specifics on what is expected regarding the corrosion-inhibiting paint or the coating for the piping that is noted in the Division 21 specifications.

Response: Cheatham and NCSPA will discuss this and issue a clarification by addendum. e. Question: Will the contractor be required to clean or paint the structure?

Response: No.

f. Question: The specifications call for all piping to be Schedule 40, and for cut grooves on piping 2-1/2” and larger. This will be expensive and will cause longer fabrication time. Is Schedule 10 piping with rolled grooves allowed?

Response: Cheatham and NCSPA will discuss this and issue a clarification by addendum. g. Question: Are all phases accessible from the building exterior?

Response: Yes. There are roll-up doors on the north and south sides within the areas of all phases.

h. Question: Each phase encompasses three “bays” created by column lines. Will all three bays within the area of a single phase be cleared of product at the same time?

Response: The original intent of NCSPA was to have work occur by bay. However, since all three bays in a single phase are part of the same sprinkler system, this will not work. NCSPA to coordinate with their operations to ensure that the area encompassed by an entire phase (three bays) will be cleared of product while work is happening for that phase. i. Question: Are existing hangers allowed to be reused?

Response: No. Hangers are to be new, per the specifications.

j. It was noted that, per the plans, existing structural penetrations are to be reused. k. Question: Are the existing hanger inserts in the roof deck allowed to be reused?

Response: No. All hanger materials are to be new. The specifications do not allow for hangers to be fastened to the roof deck. Hangers may attach to the side of the existing structure.

l. Question: Is any of the existing piping allowed to be reused?

Response: No. All piping materials shall be new per the bid documents. m. Question: Area the existing riser rooms to remain elevated?

Response: Yes, per the bid documents.

n. Question: Is there any intent to salvage any of the existing materials that are to be demolished?

Response: No.

o. Question: Should random vehicle checks be expected?

Response: Random vehicle checks may occur. Contractor(s) shall have their NCSPA badge and TWIC card on their person(s) and visible at all times.

p. Question: Are the existing riser rooms heated?

Response: Yes. Any work needed to maintain heat in the riser rooms will be by NCSPA and is outside of the scope of work for this project.

q. Question: The mains running along the north side of the building is currently supported by angle brackets. Can the existing holes be used for the angle brackets as long as new angle brackets are provided?

(8)

r. Question: May the contractor use NCSPA power if there is a circuit close by? Response: Yes.

s. Question: Is the electrical wiring to the nitrogen generators included in the scope of work? Response: Yes, per the bid documents.

t. Question: Can nitrogen generators that are rated less than the 7.5 HP indicated on the plans be used?

Response: The 7.5 HP rating is a result of calculations performed by Cheatham and Associates, and we feel it is the minimum horsepower required per nitrogen generator due to the high volume of the systems. Per the specifications, the contractor shall provide calculations for Cheatham to review during construction. If it can be proven via the contractor’s calculations that lower horsepower nitrogen generators will suffice, then they may be installed. However, this review will not occur until after bid opening, and it is expected that the bidders will include the cost of the 7.5 HP nitrogen generators in their bid. If lower HP nitrogen generators are found to be sufficient upon review of the contractor’s calculations, then a credit is expected to be given to NCSPA.

u. Question: Existing air compressor wiring appears to be fairly new. Can this be reused to feed the nitrogen generators?

Response: Cheatham will investigate this and issue a clarification by addendum. v. Question: Who is the existing fire alarm manufacturer?

Response: Cheatham will investigate this and issue a clarification by addendum. w. Question: Are all bidders required to be general contractors?

Response: Cheatham will investigate this and issue a clarification by addendum. x. Question: Are license numbers required to be on the bid form?

Response: No. G. Site Visit:

1. A site walkthrough took place.

H. Meeting was adjourned.
