B08 - Solicitation AMD 0005: The reason for this amendment is to address the question received pertaining to manufacturing lead time of 2-years for the requirement in the specifications for 1500 HP motor components: USACE reached out to representatives regarding solutions to long lead times and discussed remanufactured engines. These engines will satisfy the requirements of the specifications and will have a lead time of approximately 6 months which would work in the project contract duration. Although the current specs do not prohibit remanufactured engines, this amendment is to make it clear that remanufactured engines are allowed and the requirements for them.
