Any new I-beam grating support shall be coated with an epoxy primer and topcoat to match the color of the existing grating support beams. Any pit area with cover plates/grating that is expected to have forklifts or other heavy moving equipment make contact with the cover plate/grating during the loading or unloading of material, the cover plates/grating shall be designed so it can support a 6K-forklift (Make/Year: Toyota /2017Model: 8FGU32) with a total loaded weight of 16,360lbs for loading and unloading areas of the machine. Heavy load supporting grating area shall be painted and distinguished with special markings to be clearly identified. Installation of walkways shall comply with OSHA minimum walking/working surface width requirements (see OSHA standard referenced in Section 2.1.1). Justification For Amendment: This paragraph needs to be added being that the vendor is providing closure grating around the pit for safety in accordance with OSHA 29 CFR 1910. 2. Extend the solicitation close date. The solicitation close date is extended to COB December 23, 2025. 3. All offers will be considered valid for 120 days from the closing date in this amendment. 4.
