The following changes are made to the Specifications:

SECTION 05 59 20 FABRICATION OF HYDRAULIC STEEL STRUCTURES. Paragraph 1.3.7 which currently reads:

1.3.7 Fracture Critical Members (FCM)

FCM are shown on the Contract Drawings and include all attachments and connections to these members as defined in AWS D1.5M/D1.5. All FCMs to be welded must be constructed of ASTM A709/A709M, Grade 50 F3 base material, using killed fine-grain mill practice, unless otherwise shown or specified.

All other steel material used for the construction of the miter gates must meet ASTM A709, Grade 50, Zone 3 toughness requirements for non fracture critical members, unless noted otherwise on the contract drawings. Mill repairs of base metal are prohibited. Unless otherwise indicated or specified, meet toughness requirements for fracture critical members in tension in accordance with ASTM A709/A709M for Zone 3. All materials used for the construction of fracture critical components must meet the applicable requirements of ASTM A709/A709M for fracture critical components. Welding for fracture critical members must meet all requirements of AWS D1.5M/D1.5 AASHTO/AWS Fracture Control Plan (FCP) for Nonredundant Members Clause.

Is changed to read:

1.3.7 Fracture Critical Members (FCM)

FCM are shown on the Contract Drawings and include all attachments and connections to these members as defined in AWS D1.5M/D1.5. All FCMs to be welded must be constructed of ASTM A709/A709M, Grade 50 F3 base material, using killed fine-grain mill practice, unless noted otherwise on the drawings or specified. Mill repairs of base metal are prohibited. Unless noted otherwise on the drawings or specified, meet toughness requirements for fracture critical members in tension in accordance with ASTM A709/A709M for Zone 3.

Welding for fracture critical members must meet all requirements of AWS D1.5M/D1.5 AASHTO/AWS Fracture Control Plan (FCP) for Nonredundant Members Clause.

SECTION 05 59 20 FABRICATION OF HYDRAULIC STEEL STRUCTURES. Paragraph 1.3.7.2 which currently reads:

1.3.7.2 Non-Fracture Critical Members

All non-fracture critical members shall be constructed from ASTM A709 Grade 50 or ASTM A36/A36M as shown on the drawings.

1.3.7.2 Non-Fracture Critical Members

All non-fracture critical members must be constructed from steel that meets ASTM A709 Grade 50T, Zone 3, and meet toughness requirements for non-facture critical members unless noted otherwise on the drawings.

SECTION 09 97 02 PAINTING: HYDRAULIC STRUCTURES. Paragraph 3.5 Which currently reads:

3.5 Painting Schedule SYSTEM NO. 5-E-Z

Items or surfaces to be coated: All ferrous surfaces, except for friction type connections (excluding stainless steel surfaces, and rubber seals).

3.5 Painting Schedule SYSTEM NO. 5-E-Z

Items or surfaces to be coated: All ferrous surfaces (excluding two contacting ferrous surfaces, stainless steel surfaces, and rubber seals unless the nonmetal surface is in contact with a metal surface). Refer to paragraph Contacting Surfaces within this section for further clarification.

SECTION 09 97 02 PAINTING: HYDRAULIC STRUCTURES. Paragraph 3.2.9.3 Which currently reads:

3.2.9.3 Repair of Vinyl Coating Defects

Coating defects should be repaired when they are first observed but must be repaired prior to coating acceptance. Runs and sags may be brushed out before becoming dry. Pinholes must be physically closed by scrubbing with a brush wet with ketone solvent before the succeeding coat is applied.

Overspray that will not be melted smooth by the succeeding coat must be removed by scrubbing with a brush wet with ketone solvent. Minor overspray in the final coat that results only in a reduced gloss at the outer limits of the spray pattern is not considered a defect and requires no additional attention. Insufficient thickness or incomplete hiding must be corrected with additional paint before the succeeding coat is applied. If any defect extends to the substrate, it must be determined if the substrate is corroding. In the case of pinholes it may be necessary to use magnification to observe the substrate. If the substrate is showing any corrosion, the required surface preparation must be restored by spot blasting, and the entire coating system replaced at that location.

Following the spot blasting the edges of the remaining coating must be scrubbed with ketone solvent to assure all remaining coating is tightly adhering before the new coating is applied. If VZ-108 does not receive the required succeeding coat within the required 8 days, it must be removed by abrasive blasting and replaced.

Paragraph number changed (added 3.2.5 Contacting Services) and the bottom paragraph added;

now changed to read:

3.2.10.4 Repair of Vinyl Coating Defects

Coating defects should be repaired when they are first observed but must be repaired prior to coating acceptance. Runs and sags may be brushed out before becoming dry. Pinholes must be physically closed by scrubbing with a brush wet with ketone solvent before the succeeding coat is applied.

Overspray that will not be melted smooth by the succeeding coat must be removed by scrubbing with a brush wet with ketone solvent. Minor overspray in the final coat that results only in a reduced gloss at the outer limits of the spray pattern is not considered a defect and requires no additional attention. Insufficient thickness or incomplete hiding must be corrected with additional paint before the succeeding coat is applied.

If VZ-108 does not receive the required succeeding coat within the required 8 days, it must be removed by abrasive blasting and replaced.

For connection bolt tensioning sessions, the same paint application process specified herein applies. Once the initial coat of V-766e is applied there is no recoat window.

SECTION 09 97 02 PAINTING: HYDRAULIC STRUCTURES. Added Paragraph 3.2.5 Which reads:

a. 3.2.5 Contacting Surfaces When riveted or ordinary bolted contact is to exist between surfaces of ferrous or other metal parts of substantially similar chemical composition, such surfaces will not be required to be painted, but any resulting crevices must subsequently be filled or sealed with the three coat 5-E-Z paint system as specified. Where a nonmetal surface is to be in riveted or bolted contact with a metal surface, the contacting surfaces of the metal must be cleaned and given three coats of the 5-E-Z paint system. Unless otherwise specified, corrosion-resisting metal surfaces, including cladding therewith, must not be painted.

SECTION A - SOLICITATION/CONTRACT FORM

The required response date/time has changed from 23-Jul-2024 02:00 PM to 30-Jul-2024 02:00 PM.
