Hi Kim,

FYI, DPW ts in the process of preparing the attached Change Order for transmittal to you for the Mayor's signature. The Change Order is in the amount of
$10,710 and does not require BPW or Finance Committee approval.

This change order is the result of unknown conditions. It was unknown there would be conduit below the floor slab until the contractor removed the concrete.
The conduit needs to be relocated in order for work to continue. The project is on hold until the Change Order is approved.

Wanted you to have the background on the Change Order and be able to review with Mayor for his signature/approval ASAP.

(Mary Woods will be hand delivering the document with Transmittal sheet this afternoon.)

Please let me know if any additional information is required to complete approval.

Thank you,

Carolyn
