The following have been added by full text:

QUESTIONS AND ANSWERS VOL. 2

Q1. In reference with miter gate anchorage assemblies as per drawings S-5029 thru S-5032 and fracture critical notes #2 & 3 on drawing S-5030 & S-5031. Does the fracture critical requirement apply to all forgings for miter gate anchorage or just the items associated with see note statement under details for anchor bar 1, anchor bar 2 & gudgeon link only?

A1. Note #2 and #3 on drawings S-5030 and S-5031 apply to anchor bar 1, anchor bar 2, and gudgeon link only.

In regards to Note #2, all other forgings are to be tested using industry/ASTM standards for ensuring quality materials, unless otherwise specified in the specifications.

In regards to Note #3, the location of the HSS identification numbers is shown on the drawings for each of the applicable components.

Q2. In reference with miter gate 3-D model drawings as per drawings S-9051 thru S-9052, can you provide the 3-D model drawings for checking weights?

In reference with S-9052 miter & quoin assemblies, the diaphragm plates are part of the quoin assembly detail and the diaphragm plates are not shown on the miter assembly. Was the diaphragm plates not shown on miter assembly for reference clarification or is the miter assembly section fabricated without diaphragms?

A2. The Government will not provide the 3-D model.

The diaphragm plates are not shown for clarity. The intent of the 3-D model views shown on drawings S-9049 thru S-9052 is to aid in visualizing the 2-D drawings. These drawings are not intended to dictate fabrication means, methods, assemblies, or sequencing.

Q3. In reference with miter gate anchorage assemblies as per drawings S-5029 thru S-5032 and fracture critical notes# 2 on drawing S-5030 & S-5031. Does the fracture critical requirement apply to all forgings for miter gate anchorage or just the items associated with FCM & see note statement under details for anchor bar 1, anchor bar 2 & gudgeon link only? Note #2 fracture critical requirement note states radiographic testing of material.

What are the CVN requirements needed on the A668 Class K material to meet FCM?

W911WN19B0002

A3. Note that the material class of the anchor bars and gudgeon links has been revised to Class D as part of Amendment 2. The minimum CVN requirements for the FCM needs to match that of ASTM A709 Grade 50F Zone 2.
