12. The spec [Section 105626] in 2.5.B.3 calls out for 48" widths on the shelving. Since this is an industrial application, wouldn't the use of Industrial Wide Span, possibly using 2-72" wide versus 3-

48” wide to make up the 12 length per carriage, be more end-user friendly? This would eliminate the extra limitation (obstruction) of the added uprights.

Response 12: Provide 48-inches deep by 72-Inches wide shelf units with no closed backs or dividers. Each shelf is to have a capacity of 500 pounds. See changes to Specification Section

105626 listed further below.

13. The spec [Section 105626] in 2.5.B.5 calls out for a 24" depth shelf. Since the carriages are drawn as

48" depth, this would seem to mean that the 24" depth will be placed back to back on the 48" carriage. With the application being totally industrial, with bulk storage, is there a need for 24" depth shelving, versus using a full 48" depth thru shelf?

Response 13: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or

105626 listed further below.

14. The spec [Section 105626] in 2.5.B.6 calls out for adjustable dividers on 30% of the shelving, with five dividers per shelf. Since this is industrial storage, were adjustable dividers needed in this system?

Response 14: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or

105626 listed further below.

15. The spec [Section 105626] in 2.5.E called out for Closed Backs. With the need for thru shelving storage capability, where would these closed backs be needed?

Response 15: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or

105626 listed further below.

16. The spec [Section 105626] in 2.5 F calls out for Center Dividers. These are typically needed of the shelves are to be 24/24 back to back and controlled separation is needed between the shelves.

Should these be provided since end users seem to prefer all thru shelving capabilities?

Response 16: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or

105626 listed further below.

17. The spec [Section 105626] in 2.5.H.1 calls out for a minimum of 3/4 high shelf supports. Will this meet the end users need for minimum load tolerances? I recall there were applications in the dept.

where possible loads of 400 Lbs. per shelf were expected.

Response 17: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or

105626 listed further below.

18. The drawing shows one of the Stationary Platforms located nearest the exit door. It also shows three small cabinets with doors backed up against this Stationary Platform. Is this where the Closed

Backs were needed, on one the platform side butting up against the three cabinets?

Response 18: Both end units can remain stationary. Closed backs are not required.

19. Mobile Storage Shelving Questions (Section 105626, 2.5):

A. Shelf total discrepancy: In Paragraph 105626, 2.5, B, subsection 6a and 6b, it states there are a total of (224) shelves. If there are (5) 24"D x 48"W shelves per section, (8) 48"W sections per carriage, and (7) double-faced ranges, I come up with (280) shelves, not including canopy tops. Is this correct?

Response 19, A: Provide maximum number of shelves per unit to comply with the specifications. See changes to Specification Section 105626 listed further below.

B. Adjustable partitions: Also, it calls for adjustable dividers at 30 percent of the shelves. If there are (280) total shelves (not including canopy tops), than dividers are required at (84) shelves.

On each of the (80) shelves, it seems to be calling for (5) dividers per shelf, for a total of (400) dividers. Is this correct?

Response 19, B: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or

105626 listed further below.

C. Closed backs: Each carriage is 48" deep, comprised of back-to-back shelving ranges that are

24" deep. Paragraph E seems to call for closed backs, which could be interpreted to mean the

(2) 24" deep shelving ranges should be divided by full height closed backs. In essence, this would make each 24" deep x 48" wide shelving unit a closed cabinet. Is this correct?

Response 19, C: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or dividers. Each shelf is to have a capacity of 500 pounds. See changes to Specification

Section 105626 listed further below.

D. Stationary shelving range near wall: It appears that one of the stationary shelving units is adjacent to a wall on one side of its full length. If there are closed backs, or center dividers for adjustable partitions / dividers, on this stationary shelving range, it would restrict access to the side of the unit closest to the wall. Should this unit be mobile, instead of stationary?

Response 19, D: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or dividers. Each shelf is to have a capacity of 500 pounds. See changes to Specification

Section 105626 listed further below.

E. Center dividers: For the adjustable partitions to function, slotted center dividers are needed.

So, for the 30 percent of shelves that have adjustable dividers, the center dividers are necessary. Are the center dividers required for the other 70% of the shelves?

Response 19, E: Provide 48-inches deep by 72-inches wide shelf units with no closed backs or

105626 listed further below.

20. Please provide a mechanical schedule for Unit Heaters.

Were these rates for utilities ever released? Also please verify that the General Contractor is responsible to include in their bids any and all cost of utilities (water, electricity, etc…) required for the project. The wording in this section is a bit confusing when referring to reimbursement.

Response 29: See Amendment 1, posted Mar 22, 2011, “Amendment U0001 Specifications” section, item 3, for clarifications to the reimbursement procedure. The Government will bill the contractor $.12/KWH for electricity. Water rates will be set by the City of Portsmouth. Natural Gas rates will set by the gas utility company.
