Amendment No. 2 to Solicitation RFP 388000kmb for Bar Grating and Saddle Clips
This amendment extends the proposal due date from 5:00 PM CT on Friday, November 6, 2026, to 5:00 PM CT on Friday, November 13, 2026. Fermi Forward Discovery Group, LLC issued the original RFP on October 21, 2026, for the procurement of bar grating and saddle clips. Bidders must acknowledge this amendment prior to the new due date by completing SARC and PROC-FRM-466 forms or by email. Changes to previously submitted bids may be submitted via email if they reference both the solicitation number and this amendment and are received before the deadline.
The amendment provides nine technical clarifications to the original specification. Key responses include: (1) saddle clips must be compatible with 1.5-inch bearing bar height and specified flange thickness; (2) manufacturer load tables are acceptable for demonstrating compliance with 100 PSF live load, 1,000 lb concentrated load, and 0.25-inch maximum deflection over 48-inch span; (3) 1/4-inch bar grating rods may be either twisted or flat if deflection limitations are met; (4) standard 19-W-4 grating width tolerances are acceptable, with smaller sizes preferred for Items 6 and 7; (5) galvanized G-style clamping assemblies are acceptable as substitutes for Type W44/W10 saddle clips if compatible with specified beam flanges (1,768 assemblies for W44×290 beams and 352 for W10×49 beams) and flush to the walking surface; (6) the 1,000-pound line load specification means lbs/ft of width at mid-span; (7) 11 PSF represents maximum self-weight (dead load allowance); (8) the 24-inch maximum panel width is nominal with two exception infill panels at 25.875 inches; and (9) mill certification and Certificate of Conformance copies are required at delivery. All other terms and conditions remain unchanged. Contact: Karen Berger, Procurement Specialist III, kberger@fnal.gov, 630-840-4344.

TITLE OF PROJECT:
BAR GRATING AND SADDLE CLIPS
Bidders must acknowledge this Amendment prior to the hour and date set forth in the solicitation by one of the following methods:
1. By completing the SARC and PROC-FRM-466, or
2. By email.
If by virtue of this Amendment you desire to change a bid already submitted, such change may be made by email, provided such email reference the Solicitation and this Amendment, and is received prior to the due date hour.
The above reference Solicitation is amended as follows:
This amendment extends the due date one week, from 5:00 PM CT, Friday, November 6, 2026, to 5:00 PM CT, Friday, November 13, 2026.
This amendment provides clarification to the technical specification:
1. Regarding the saddle clips, please confirm what W44 and W10 refer to - are they specific manufacturer part numbers, or a designation tied to the beam flanges (W44x290 and W10x49)?
Response: The required clip is compatible with the 1.5" bearing bar height and the flange thickness per the drawing.
2. Is it acceptable to provide the manufacturer's published load table to demonstrate compliance with the
100 PSF live load, 1,000 lb concentrated load, and 0.25 inch maximum deflection over a 48 inch span?
Response: Mfg load tables are sufficient for compliance.
3. Does bar grating 1/4in rod have to be twisted or can it be flat?
Response: Either way works, as long as the deflection limitations can be achieved with the relevant bearing bar configuration.
4. Are the following standard 19-W-4 grating widths acceptable? For Items 6 and 7, please identify the acceptable option Items 1, 3, and 4: 23.9375″ instead of 24″.
Items 2, 5, and 8: 12.0625″ instead of 12″.
Item 6: 25.125″ or 26.3125″ instead of 25.875″.
Item 7: 13.25″ or 14.4375″ instead of 13.875″.
Response: Panel sizes would be adequate, and for 6& 7 the smaller size would be acceptable.
5. Are complete galvanized G-style clamping assemblies acceptable in place of the listed Type W44/W10 saddle clips—1,768 assemblies for W44×290 beams and 352 for W10×49 beams—provided they properly clamp the specified beam flanges and secure the grating?
Response: G-clips are acceptable, if compatible with the 2 flange sizes specified. Goal is to have top of clip flush to the walking surface
6. Section 3 specifies a minimum 1,000-pound line load at mid-span and a nominal maximum deflection of 0.25″. Does this mean 1,000 pounds total across each panel’s width or 1,000 pounds per linear foot of panel width?
Response: Unit is lbs/ft of width at mid span
7. Is 11 PSF a design dead-load allowance or a required finished-product weight?
Response: 11PSF is maximum self-weight (dead load allowance)
8. Section 3 the SOW’s states 24″ maximum panel width, but Item 6’s specified 25.875″ width.
Response: 24” is nominal requirement for the SOW. There are 2 infill panels that are close to this (exception). The drawing is accurate.
9. A copy of both the mill certification and CoC are required with delivery.
All other terms and conditions remain unchanged.
