1.0 STRUCTURAL STEEL

1.1 FABRICATOR TO BE CERTIFIED UNDER AISC QUALITY CERTIFICATION PROGRAM WITH

ONE OF THE FOLLOWING CERTIFICATIONS; MAJOR BRIDGE FABRICATOR (CBR),

CERTIFIED BRIDGE FABRICATOR - ADVANCED (ABR), CERTIFIED BRIDGE FABRICATOR -

INTERMEDIATE (IBR), OR CERTIFIED HYDRAULIC FABRICATOR - ADVANCED (HYDA) AT

THE TIME OF BID. IN ADDITION, THE FABRICATOR IS REQUIRED TO BE CERTIFIED WITH

FRACTURE CRITICAL ENDORSEMENT (FCE) AT TIME OF BID. THE FABRICATOR SHALL

BE CERTIFIED FOR THE LIFE OF THE CONTRACT.

1.2 ALL DIMENSIONS, DISTANCES AND ANGLES SHOWN ARE PER THE ORIGINAL

CONTRACT DRAWINGS. THE CONTRACTOR SHALL FIELD VERIFY ALL CONTROL

DIMENSIONS OF EXISTING BULKHEADS PRIOR TO BEGINNING FABRICATION AND SHALL

DOCUMENT ALL VARIANCES IN SHOP DRAWINGS SHOWING CLOUDED VARIANCES FOR

GOVERNMENT APPROVAL.

1.3 UNLESS OTHERWISE NOTED, ALL STRUCTURAL STEEL USED IN FABRICATION OF THE

BULKHEADS SHALL BE ASTM A709 T2 GRD 50, EXCEPT FRACTURE CRITICAL MEMBERS

WHICH SHALL BE ASTM A709 F2 GRD 50. FOR REQUIREMENTS, SEE SPECIFICATION

05 59 13.01 26.

1.4 CONFORM ALL STRUCTURAL WELDING TO ALL REQUIREMENTS AS STATED IN 05 59

13.01 26 FOR CONNECTIONS.

1.5 ALL WELDS NOT SHOWN ON THE CONTRACT DRAWINGS SHOULD BE ASSUMED TO BE

FRACTURE CRITICAL CJP WELDS, AND ARE TO BE IDENTIFIED ON THE SHOP

DRAWINGS AND CLOUDED FOR APPROVAL. PROVIDE ALL MISSING WELDS ADDED BY

THE CONTRACTOR TO THE SHOP DRAWINGS IN LIST FORM IDENTIFYING WHICH SHOP

DRAWING SHEET THE WELD IS LOCATED ON. ADD THIS LIST TO THE FIRST PAGE OF

THE SHOP DRAWINGS AND PROVIDE THE LIST FOR GOVERNMENT APPROVAL.

1.6 BREAK ALL SHARP EDGES TO A 1/16" RADII, UNLESS NOTED OTHERWISE. A SHARP

EDGE IS DEFINED AS ANY EDGE THAT IS THE RESULT OF SHEARING, FLAME CUTTING

OR MACHINING. BREAK ALL DRAIN HOLE EDGES TO A 1/8" RADII UNLESS NOTED

OTHERWISE

1.7 CONFORM PAINTING FOR DRAFT TUBE BULKHEADS TO ALL REQUIREMENTS STATED

IN SPECIFICATION 09 97 02.13 26. USE SYSTEM 5-E-Z FOR ALL BULKHEAD

COMPONENTS, EXCEPT AS NOTED IN THE SPECIFICATIONS. CERTIFY ALL PAINTING

CONTRACTORS ENGAGED IN SURFACE PREPARATION AND COATING APPLICATION

ACCORDING PER 09 97 02.13 26.

1.8 ALL WELD ACCESS HOLES ARE 2" RADIUS AND GROUND TO A MAXIMUM 1,000 ΜINCH

FINISH, UNLESS OTHERWISE NOTED. EXTEND SLOTTED ACCESS HOLES 2" PAST WELD

JOINT, UNLESS OTHERWISE NOTED.

1.9 WRAP ALL WELDS USING THE REQUIRED FILLET WELDS SIZE SHOWN ON THE

DRAWINGS, OR THE REQUIRED REINFORCING FILLET WELD SIZE PER AWS D1.5.

MATCH ADJACENT WELD SIZES AT LOCATIONS THAT ARE TO BE WRAPPED.

1.10 THE ESTIMATED DRY WEIGHT OF EACH BULKHEAD SECTION, NOT INCLUDING PAINT

AND WELDS: LEAF - 33500.0 LBS

1.11 ALL BOLT HOLES ARE TO BE STANDARD SIZE, UNLESS NOTED OTHERWISE.

1.12 PREHEAT WELDED JOINTS FOR THE THICKER PART JOINED. SEE SECTION

05 59 13.01 26.

1.13 MATCH DRILL HOLES AT ASSEMBLY FOR RUBBER SEALS.

1.14 SPLICES IN STEEL MEMBERS ARE NOT ALLOWED, UNLESS NOTED OTHERWISE,

WITHOUT GOVERNMENT APPROVAL. ALL WELDS IN SPLICES APPROVED BY THE

GOVERNMENT ARE TO BE CONSIDERED CRITICAL.

1.15 ASSUME ALL WELDS ON FRACTURE CRITICAL MEMBERS ARE IN TENSION FOR

PURPOSES OF NONDESTRUCTUIVE TESTING.

1.16 SOME COMPONENTS AND FEATURES MAY BE OMITTED FOR CLARITY AND/OR MAY

NOT BE TO SCALE IN CERTAIN VIEWS WITHIN THIS PACKAGE.

1.17 ALL CJP BUTT JOINTS ARE TO BE GROUND FLUSH, UNLESS NOTED OTHERWISE.

1.18 THERE ARE INTERSECTING WELDS LOCATED AT THE CORNERS OF THE TOP AND

BOTTOM WEBS, 16 WELD JOINTS IN TOTAL. THESE WELDS ARE SUBJECT TO TENSILE

STRESS. THE GREATEST DIMENSION ON ANY POROSITY OF FUSION-TYPE

DISCONTINUITY THAT IS 1/16 IN OR LARGER IN GREATEST DIMENSION SHALL NOT

EXCEED THE SIZE FOR THE EFFECTIVE THROAT OR WELD SIZE INVOLVED. THE

DISTANCE FROM ANY POROSITY OR FUSION-TYPE DISCONTINUITY DESCRIBED ABOVE

TO ANOTHER SUCH DISCONTINUITY, TO AN EDGE, OR TO THE TOE OR ROOT OF ANY

INTERSECTING FLANGE-TO-WEB WELD SHALL BE NOT LESS THAN THE MINIMUM

CLEARANCE ALLOWED OR THE SIZE OF DISCONTINUITY UNDER EXAMINATION.

2.0 DESIGN STANDARDS

2.1 AISC 325 - STEEL CONSTRUCTION MANUAL 15TH EDITION

2.2 AWS D1.5 - 2020

2.3 EM 1110 - 2 - 2107

3.0 QUANTITY

3.1 ALL QUANTITIES INDICATED ON STRUCTURAL SHEETS ARE FOR 1 BULKHEAD. SEE

SPECIFICATIONS FOR REQUIRED NUMBER OF BULKHEADS.

4.0 FRACTURE CRITICAL MEMBERS (FCM)

4.1 ALL FAILURE CRITICAL MEMBERS WILL BE TREATED AS A FRACTURE CRITICAL

MEMBER (FCM) FOR FABRICATION AND TESTING PURPOSES.

5.0 TOLERANCES UNLESS OTHERWISE NOTED.

5.1 TOLERANCES FOR FRACTIONAL DIMENSIONS:

5.1.1 BOTH ENDS MILLED: +/- 1/32"

5.1.2 NON-MILLED ENDS AND MEMBER LEGNTH OF 30' OR LESS: +/- 1/16"

5.1.3 NON-MILLED ENDS AND MEMBER LENGTH OVER 30': +/- 1/8"

5.2 TOLERANCES FOR ANGLES ARE +/- 0.5°.

5.3 TOLERANCES FOR DECIMAL DIMENSIONS ARE AS FOLLOWS:

DIMENSION TOLERANCE

X.X +/- 0.1

X.XX +/- 0.02

X.XXX +/- 0.01
