Project: WFP East Clearwell Roof Replacement <br /> Change Order No.02 <br /> Change Order Effective Date: 6/15/18 <br /> A. During the design submittal review process, WFP personnel noted they need to <br /> place an aluminum boat into the East Clearwell for maintenance and inspections. <br /> The existing boat would not fit through the hatch size called out in the Contract's <br /> Supplementary Conditions. Enlarging the hatch allows the existing boat to fit <br /> through the hatch. Because of the larger hatch, additional engineering was <br /> necessary to design the framing around the hatch. <br /> B. Due to the possibility of tariffs on foreign aluminum and steel, foreign suppliers <br /> placed a hold on quoting pricing to US customers. As a result, fabricators sourced <br /> from US suppliers. Lead times for standard extrusions went from 3-4 weeks out <br /> to 8-9 weeks. <br /> C. Aluminum and steel markets have been volatile. Pricing for aluminum ingots <br /> increased approximately 30% over a two-week period. Because of this, extruders <br /> slowed production to avoid purchasing ingots at the elevated price levels. This <br /> caused the lead times to increase from 8-9 weeks to 11-12 weeks. <br /> END DOCUMENT 006363 <br /> WFP East Clearwell Roof Replacement June 5,2018 <br /> WO#UP3662 006363 -4 <br />
