Written work authorization requests numbered sequentially will be used by both the Government and contractor for repair work or emergency work to be performed. Work requests from the Government will include, but is not limited to, requests to correct or perform a particular task, request a quote, and perform rework of defective service. The contractor shall provide exact location, costs for parts, materials and equipment, number of labor hours required and cost, and description of any additional materials, equipment or tasks that are necessary to accomplish the overall work. Description of work specifics shall be included. If the contractor elects to perform work or portions thereof outside normal business hours, payment shall be made at the price provided for work permitted during normal business hours. Work authorization requests approved by the COR will be returned to the contractor authorizing performance of work. The contractor shall return completed work authorizations to the COR upon completion of the work and prior to submitting an invoice. A work authorization form will be provided to the contractor upon contract award and shall be used along with the contractor’s service call log to ensure work completion. Subject to the dollar limitations in the below paragraph, if the COR determines that the repair is an emergency, the COR may verbally authorize the contractor to perform repairs.

The contractor shall submit a work authorization request the next business day.

Single repairs less than $7500.00 or cumulative repairs less than $7500.00 in a given year may be requested and authorized under this purchase order by the Contracting Officer’s Representative.
