01 - The definition does not…

01 - The definition does not include all types of metal piles. How do we ensure that all metal piles are included. For example: Helical Piles, micro piles, etc... Perhaps a more generic definition that would account for any metal pile would be more appropriate.

Since rebar and structual steel is also included in this specification, should there be a definition OR since there could be several different types of steel product (expansion joints, girders, plates, poles, steel beam guiderail, etc...) should there be a generic definition of metal products?

03 - It would be helpful if the specification provided a more specific website addresses and some direction as to how to find the steel price index.

04 - Not sure how the steel identified in table 1 will be populated and what happens if the steel we are considering to purchase is not in the list.

06 - The payment adjustment for changes in the steel price index shall be applied only when the difference between the published steel price index in the month and year for when the steel adjustment is made, and the published steel price index in the month prior to tender closing is great (add er to the end of the word "great") than or equal to a 10% difference.

07 - The payment adjustment for reinforcing steel bars, and piles shall be calculated and applied based on the month of installation into the Work.
Why is this only for rebar and piles?
If the rebar is to be based on the month when the installation takes place could this cause cost differences if the material was purchased for a specific scheduled installation but the project was delayed and the rebar is installed significantly later.

10 - The definition for R includes values for steel that can vary. Should we identify an index or something like that to be reference as a value of material.

NOTES TO DESIGNER:
What about other steel like Girders, expansion joints, plates, poles, sign structures, steel beam guiderail, etc... some of these are not structure related but still involve significant quantities of steel.
