QUESTIONS AND ANSWERS

1. On drawing 64W274-4, the jack arm, jack screw, and lock nut are all Type 304 & 316 Stainless Steel. Shouldn’t these be made of different materials so they will not gall together once installed?

Answer: The components referenced the drawing are to remain stainless steel 304 and 316. The operability of the structure is infrequent and the difference in material properties between 304 and 316 have been successful in the past. Installation measures will be followed as stated in Technical Specification Section 3.1.1 to include the application of "Marine grade" anti-galling compound with the addition of spare (40 oz.) compound for future use.

2. On drawing 64W274-4, the valve stem extension has a dimension of 72’-6”. There are no field segmented sections shown. Vendors will not be able to ship in one piece, nor is the Corps going to be able to install in one piece. Please provide segmented connection details.

Answer: Valve Stem Extension (64W274-4) can be split into 2 or 4 segments, 2 segments at 40' or 4 segments at 20'. Pipe will be field cut to match exact dimension needed. Connection method and details to be determined by contractor and submitted to government for approval. If welding is needed for the connection, it shall be noted and will be completed in the field by the government during the submittal period.

3. Technical Specification Section 05 59 13 Fabrication of Hydraulic Steel Structures states that all welding is to be per AWS D1.1, however Drawing 64W274-2 Note 7 states that welding is to be per AWS D1.5. Which is correct?

Answer: AWS D1.1 is to be used.

4. Technical Specification Section 05 59 13 Fabrication of Hydraulic Steel Structures Paragraph 1.3.2 states that structural steel shall be ASTM A709 Grade 50 and that the toughness requirements stated in section 10 are to be met. No where does the Government list the toughness requirements. Is it Non-Fracture Critical and to what Zone and temperature?

Answer: This is a non-fracture critical member. Technical Specification Section 05 59 13, Par. 1.3.2 - Structural Members shall be deleted and be replaced with the following paragraph:

"Structural steel shall be ASTM A709/A709M, grade as specified or shown on the drawings. Contractor shall submit the material test report for government approval."

5. May the seal clamp bars and spacer bars noted in drawing 64W274-2-5 through 9 be made out of A36 material?

Answer: Yes, ASTM A36 or ASTM A572 GR.50 is acceptable as an alternative.
