Solicitation No. 70Z04020Q6109200 Amendment No. A00002

Overhead Gantry Crane and Column-Mounted Jib Cranes

Clarifications to Amendment A00001

1. QUESTION: Please confirm the requirements for the jib crane mounts and update the drawing(s) as needed. The PWS states that nine (9) column-mounted jib cranes are required. As referenced in Question 54 of Amendment A00001, the drawing A00001_Engine Overhaul Facility, shows three (3) of the jib cranes with floor mounts Clarification is required as there are cost implications for changing the requirement for nine (9) column-mounted jib cranes.

RESPONSE: All nine (9) jib cranes shall be mounted to the vertical girders of the bridge crane.

2. QUESTION: If the requirement for nine (9) column-mounted jib cranes has changed, request an extension through Monday, May 12, 2020.

RESPONSE: We are unable to extend the due date for proposal submissions. The proposals are due April 29, 2020 by 11:00am EST.

3. QUESTION: Should the Jib Crane span be 12 feet or 10 feet? Typically, if a hoist must travel 10 feet, then a jib crane span of 12 feet should be required. We believe the correct span should be 12 feet since Section 2.2 of the PWS states that the “jib crane hoist shall be able to travel the entire distance across the 10 ft. jib arm.”

RESPONSE: The jib crane is to be 10 ft long and must travel the entire distance across the bar.

4. QUESTION: Please provide the missing information in paragraph (g) on page 17 of 19 in the “Combined Synopsis_Solicitation_Overhead Gantry Crane and Column Mounted Jib Cranes”. There is no information following the colon at the end of paragraph (g).

RESPONSE: There was a formatting oversight on page 17 of the solicitation. I have corrected the formatting and attached an updated Combines Synopsis_Solicitation_Overhead Gantry Crane and Column Mounted Job Cranes.R1. Only the formatting has changed, none of the details of the solicitation have changed.

5. QUESTION: Please confirm which type of crane you are looking for, top running double girder crane or some type of gantry crane with a freestanding runway.

RESPONSE: To clarify, we are looking for a top running double girder crane and freestanding runway in accordance with the pictures that were posted.

6. QUESTION: Can we quote a single girder crane?

RESPONSE: No, we are looking for a top running double girder crane and freestanding runway in accordance with the pictures that were posted.

7. QUESTION: Question 11 states no height restrictions, but Question 39 states 21’-6” to the lowest obstruction? Please clarify.

RESPONSE: The lowest height obstruction in the building is approximately 22 ft.

8. QUESTION: Referencing PWS Section 2.2, is a push-type Jib Crane Trolley acceptable? Please confirm that the column mounted Jib Cranes must move by air or electricity; this includes slewing (left and right), trolley (in and out) and hoist (up and down). There would be very significant cost savings for USCG FLC if the air and electricity requirements were removed for the slewing and trolley movements; the hoist (up and down) movements would remain powered by air or electricity.

RESPONSE: The rotation of the jib should be manual. The jib crane is operated by air or electric. The PWS says contractor will decide if air or electric

9. QUESTION: Can we tie the crane back to the building for support?

RESPONSE: No the crane must be free standing.
