To whom it may concern,

This letter is to notify you that we have been encountering significant delays in the procurement of the materials needed to fabricate traffic sign structures.

We have encountered much longer than normal lead times to receive chord pipe, steel plate, and other material items. For example, any chord pipe over 42' requires a dedicated mill run since chord splices are no longer an option. However, if our order to the mill does not satisfy a full run, the mill waits for additional orders from other customers before they perform the run. In some instances, we have been given expected delivery dates from the mills but receive the chord pipe 1-2 months past the due dates. This lack of material and clear visibility as to when our material orders will arrive at the plant makes it impossible to provide a schedule to our customer that does not change.

We will continue to provide estimated delivery dates based on our normal lead times for production, but please note that these dates are contingent upon us receiving the material. Our normal lead times are currently 18 weeks. If multiple structures are released on the same day or in close proximity, one additional week will be added per structure. Subsequent updates will be provided if we anticipate that the original estimated delivery date will not be met.

Currently the ETA on Arcosa's' Job# 5793 (AIS PO# 2109-21031001-AF) is anticipated to be completed on time for structures A-OH02 (11/24/2021) & A-OH03 (12/6/2021), the remaining materials for this order are due to arrive at our plant at the end of September.

Please let me know if you need any additional information.

Sincerely,

DocuSigned by: Alan Ferguson 39662C3F92194B0...
