The change order proposal includes a credit for the original coating, the increased material cost for the new coating, and additional labor, equipment, supervision, and subsistence for the added amount of time HCl will be painting. The added amount of time HCl will be painting is because the new coating is a thicker high solids product that does not spray as well as the original coating, therefore the change order includes the added cost for an additional stripe coat (coating by hand of angles, edges, crevices, welds where the coating will be harder to apply than the original coating). Sherwin Williams has confirmed that the coating would require an additional stripe coat, particularly with the complex structure of the elevated tank. The subsistence item is the indirect cost associated with the additional labor required. Typically we see that built into the labor cost (Additional Stripe Coat @ 80 hours) but HCl has broken it out and when combined, those costs are equal to an hourly rate we would expect for this work. The added benefit to the City Is the extended color and gloss retention of the coating and the additional corrosion protection of the added stripe coat. Sherwin Williams will provide a 5 year warranty for color and gloss retention instead of the 2 year warranty required by the contract. We at this point see no further issues with the change order and recommend the change order for City review and approval. Please let we know if you need further information for your process.

The change order proposal includes a credit for the original coating, the increased material cost for the new coating, and additional labor, equipment, supervision, and subsistence for the added amount of time HCI will be painting.The added amount of time HCI will be painting is because the new coating is a thicker high solids product that does not spray as well as the original coating, therefore the change order includes the added cost for an additional stripe coat (coating by hand of angles, edges, crevices, welds where the coating will be harder to apply than the original coating). Sherwin Williams has confirmed that the coating would require an additional stripe coat, particularly with the complex structure of the elevated tank. The subsistence item is the indirect cost associated with the additional labor required. Typically we see that built into the labor cost (Additional Stripe Coat @ 80 hours) but HCI has broken it out and when combined, those costs are equal to an hourly rate we would expect for this work. The added benefit to the City is the extended color and gloss retention of the coating and the additional corrosion protection of the added stripe coat. Sherwin Williams will provide a 5 year warranty for color and gloss retention instead of the 2 year warranty required by the contract. t We at this point see no further issues with the change order and recommend the change order for City review and approval. Please let me know if you need further information for your process. i Thanks, Ryan Ryan Hale, EIT, NACE Coating Inspector—Level 1 f 206.284.0860 p J 206.283.3206 f Gray& Osborne, Inc. 1 1130 Rainier Avenue South, #300, Seattle, WA 98144 .,.,. tl ,a;sP nun k2 orVio mvownvmrntl PxI ow pirinfin g this,»eaaN.
