Eglin AFB, FL Questions/Answers Set 2 20 April 2021

Questions/Responses (In Red):

In reviewing the above RFP we have the following questions:

Appendix A ;3.2.1.7.1 and 3.2.1.7.2.

Please confirm that the following specifications comply with the above sections and are acceptable.

CONFIRMED. SPECIFICATIONS ARE ACCEPTABLE. PER PARA 3.2.1.7.4, IF CROSSS BRACING IS USED IT

SHALL NOT BE LOCATED ALONG FRONT WIDTH OF MEZZANINE.

2.2 JOIST-TO-BEAM CONNECTIONS Joists are framing channels, up to 24-feet in length, used to support the mezzanine deck. Joists transfer shear loads to the main mezzanine beams through a bolted, L-shaped, shear connector. 2.3 BEAM-TO-COLUMN CONNECTIONS Beams are structural elements that transfer loads from joists to columns. Beams shall transfer shear loads to the column through a shear connector that is factory-welded to the column on its center axis. Bolt holes on the beams are pre-punched and positioned to maximize the strength and stability of the connection. 2.4 COLUMNS Columns support gravity loads transferred by the beams. In addition, columns support the lateral load resisting system that provides stability to the structure. Columns are square hollow structural sections with shop welded base plates. 2.5 BRACES A lateral force resisting system is required for lateral stability. The most effective and economical system is comprised of cross braces. The use of knee braces is acceptable, but less favorable anchoring conditions typically result from the use of knee braces (often requiring one or several of the following: larger base plates, thicker base plates, larger or longer anchor bolts, chemical anchors, footings). 2.6 BASE PLATE AND CONNECTIONS Base plates transfer column loads to the anchoring slab. Base plates shall be a minimum thickness of ½-inch. The column shall be centered on the base plate and welded around its entire perimeter. Centered base plates permit an even transfer of loads to the slab and help reduce the effects of sway on the mezzanine. In limited cases, off-centered base plates are acceptable, but unfavorable anchoring conditions typically result from the use of off-centered plates (often requiring one or several of the following attributes: larger base plates, thicker base plates, larger or longer anchor bolts, chemical anchors, footings).

Please provide system plans and specifications for existing system including connection points for system to be added.

EXACT SPECIFICATIONS ARE UNKNOWN. AS PER APP A, PARA 3.2.1.13. “The Contractor shall perform a test on the existing system to determine flow and pressure characteristics and design a system compatible with the existing system.” ASSUME CONNECTION POINT ABOVE/GENERAL AREA OF

MEZZANINE.
