Question 1: I have a question about the above referenced solicitation.

The Product Description states:

3.1 The Contractor shall design, engineer, and build custom‐built hot‐dip galvanized duty mobile catwalks for use with CCA’s.

3.4 Each catwalk shall be made of stainless‐steel hardware

Our fabricator has a concern about comingling the hot dipped galvanized catwalk with the stainless steel hardware. He states: It would be beneficial not to use stainless steel hardware. There is less chance for corrosion using Hot Dipped Galvanized hardware on Hot Dipped Galvanized steel than mixing the two different types of steel. Either that or go stainless with the whole thing (more than 5x cost).

The question being, is it acceptable to use hot dipped galvanized steel for the hardware?

ANSWER 1: See revised Product Description.

Question 2: What are the design criteria for the chain posts, simply OSHA compliance?

ANSWER 2: The chain posts shall be OSHA compliant to meet safety standards.

Question 3: Should the chain posts be designed in certain locations to accommodate work areas while in use?

ANSWER 3: See revised Product Description.

Question 4: Should the catwalk have stairs on both ends or is one end sufficient?

ANSWER 4: See revised Product Description.

Question 5: Should there be self‐closing gate at the top of the stair?

Question 8: Please clarify if requirement 3.6 ‐ Each catwalk shall have a 1,000‐pound load capacity – is total load on the assembled structure, or 1000lb per section, or 1000lb per sqft?

ANSWER 8: See revised Product Description.

Question 9: Please clarify if the 7ft height referenced in requirement 3.2 (Each catwalk shall be between 10‐foot & 11‐foot in total height (7‐foot deck height)…) is the elevation to the deck or the ‘clear height below the deck and structure’ of the catwalk

(1) The Contractor shall provide a unique item identifier for the following:
