A. ABS CLASSIFICATION

The contractor shall be responsible obtaining necessary regulatory body reviews and approvals, obtaining necessary inspections and surveys during construction and for the certification and classing of the barge as follows:

ABS classification for Maltese Cross A1, Floating Crane, Rivers and Intra-Coastal Waterways for use as a Government Floating Crane, with Reinforcement B

Other ABS Notations: CRC (Crane Register Certificate)

ABS Vessel ID No.: TBD

The recommended ABS point of contact is Mr. Robert (Bob) Smith (Manager – US

Government Programs, ABS Americas), who can be reached by phone, email or mail, at: (703) 519-9970, RSmith@eagle.org.

If the contractor intends to launch, test, operate or tow the barge “out of class”, the contractor must specifically advise ABS of such intent and incorporate any and all modifications required by that agency for such operation at no additional cost to the Government and at no additional contract time. Any such modifications which, in the opinion of the COR, affects the arrangements, operability, or suitability of the vessel shall be removed from the vessel by The contractor at no additional cost or time and the vessel returned to new condition prior to Final Acceptance.

B. VESSEL DESIGN AND CLASSIFICATION REVIEW STATUS

The Government has developed the barge’s design and drawings in accordance with ABS rules and these specifications. These drawings have not been submitted to ABS for their review or approval.

The contractor shall initiated and is responsible for the ABS Class process, including the engineering review. For the purpose of bidding, all of the contract drawings in this solicitation shall be assumed to be approved by ABS as issued. If ABS issues technical comments that require revisions to the design, the Government will coordinate with the contractor to resolve the comments and issue a contract modification(s) if required. The Government does not consider technical comments associated with final equipment selection, material selection, and/or standard shipyard construction/installation practices in the category of those that require revisions to the drawings/design. As such, those types of comments are the responsibility of the contractor.

The contractor shall be responsible for all costs associated with applications, additional plan submittals, and inspections required to obtain such certification/documentation. Please note that the Government has not designed the crane pedestal/foundation or the associated hull support structure. The contractor shall be responsible for this part of the design. In addition, the contractor shall be responsible for all ABS Surveyor comments and technical comments related to final equipment, material selection, and standard shipyard construction/installation practices.

C. VESSEL OWNER AND ADDRESS

For the ABS certificate of classification, the owner shall be listed as “U.S. Army Corps of Engineers, Norfolk District”. The owner’s address of record shall be listed as:

US ARMY CORPS OF ENGINEERS –NORFOLK DISTRICT

For specific design and engineering drawings and calculations required by the contractor, see C006.D below.

C. DRAWING CHANGES

The contract drawings represent a contract level design and are not intended to be revised by the contractor, except in way of the crane pedestal/foundation. The contractor is expected to build the barge as shown in the Contract Drawings. The Government recognizes that minor design developments may be necessary to suit the contractor’s construction and business practices. All design developments shall be provided to the COR for approval and to confirm a contract modification is not required. If approved, any design developments shall be incorporated into the As-Built drawing package as necessary.

Should the contractor find any issues with the engineering and design of the barge as it relates to this solicitation and Contract Drawing package, The contractor shall bring it to the attention of the COR for resolution. If determined necessary by the Contract Officer, an appropriate contract modification will be developed to address the issue.

D. DRAWINGS PROVIDED & REQUIRED
