SUMMARY OF CHANGES

The following have been added by full text:

QUESTION AND ANSWER

Question No 1.

The answer to Question No.3 of Amendment 0006, speaks to the “worst case” line pull, but not the speed of the line pull. The required line pull is maintained with both a 300HP motor and the theoretical 320 HP motor.

However the line speed on one layer does not meet the 400 fpm requirement. The minor loss in speed (371 fpm vs 400 fpm) would equate to a difference of only 2 fpm in actual travel speed after working through the 12 part block. This difference is not only imperceptible to the operator, but the speed is also not relevant in conditions where the max pull is required. Further, the existing dredge is currently set up for a 300HP motor. This means that the wire, breaker, drive location (due to drive frame size), and the machinery arrangement is currently set up to accommodate a 300 HP motor. Changing to a larger motor size at this time would cause an increase the cost of supply of the main components, but also require further investigation and a redesign of all of these other downstream items for little to no benefit to the government. Further, moving to a 350 HP motor (which is the next size motor) will cause additional changes to the winch itself including reducer, break size etc.

Please clarify if it is acceptable to the government to fall slightly below the 400 fpm requirement on one layer while maintaining the required full line pull.

Answer No 1.

The requirement for the new ladder hoist winch being rated for 22,374-lb. line pull at a line speed of 400 fpm across all layers shall not be revised. The Solicitation does not require a specific power rating for the new hoist winch motor or that the ratings or sizes for any other components remain the same as the existing system. The Contractor is responsible for the sizing of all equipment and components specified in the Solicitation and meeting the requirements for the new ladder hoist winch.
