ITEM 2. CRANE REMOVAL AND DISPOSAL

The existing pedestal crane, crane foundation, and all crane supporting structure above the deck plates shall be removed from the Derrickboat McCauley, in accordance with and in preparation for the installation of the new crane foundation and below deck structure as described on the design drawings

(Attachment A). The crane and all supporting structure, including all of the mechanical and electrical components of the crane, shall become the property of the Contractor, and the Contractor will have exclusive rights and responsibilities for disposal of the crane via reuse, resale, recycling, sale for scrap, etc. All materials shall be disposed of in a safe and legal manner, in accordance with all applicable local, state and federal laws and regulations. A brief listing of some potentially salvageable crane components that the Contractor will take possession of is provided as Attachment D to this Scope of Work. The

Contractor will receive these items as‐is, as salvage, and no representation is made as to condition, merchantability, or fitness for any specific purpose. The Government is not aware of any work required for this Contract that will require the Derrickboat to be placed in dry‐dock. The Contractor may elect to dry‐dock the vessel if they believe it would be advantageous to do so, but at no additional cost to the government.

Selected pages from the document “Erection Data and Spare Parts List ‐ 30 Ton Model 28H‐120BA Barge Mounted Crane,” provided with the crane when it was originally installed on the barge circa 1948, are provided for reference as Attachment C. This document is known not to reflect the current configuration of the crane due to modifications that have been made over the years. For instance, the crane operator’s cab is not elevated, and the crane was repowered in

1990 from diesel / air to hydraulics. The Contractor shall field verify any information shown in this document that is relied upon for determination of the nature, scope, and costs of the crane removal work.

The Contractor shall take any and all measures required to dismantle and remove the crane and supporting structure from the derrickboat in a manner that protects the vessel from damage, protects the environment from pollution, and protects the public and Contractor and Government personnel from harm. This includes measures to control hazardous energy, such as the potential energy stored in the crane counterweight, crane boom, and other massive components of the crane, the electrical energy in the ships power system, and the potential energy in the crane hydraulic system; measures to prevent pollution of air, water, and soil from particles, debris, and fluids such as fuel, lubricants, hydraulic fluid, and coolants.

The government has not performed a lead based paint survey of the crane. Therefore, the Contractor shall either assume that all paint on the crane contains lead, or perform a lead based paint survey of the crane to determine which surfaces are painted with lead based paint and which are not. Crane removal work that disturbs lead based paint shall be performed in accordance with the Lead Compliance Plan.

The government has not performed an asbestos survey of the crane. The Contractor shall be responsible for identifying suspect asbestos containing materials (ACM), and shall either assume that any suspect asbestos containing materials found on the crane do contain asbestos, or shall perform testing of suspect asbestos containing materials prior to disturbance to determine whether they contain asbestos. Removal, handling, and disposal of asbestos containing materials shall be performed in accordance with all local, state, and federal regulations. If found, the additional cost and time associated with removal, handling, and disposal of ACM will be addressed in a Contract modification. A sample list of suspect asbestos containing materials can be found at http://www.marinechemist.com/sample‐list‐of‐suspect‐asbestos‐containing‐materials‐acm/

Prior to commencing the crane removal work, the Contractor shall prepare and submit to the

Government for acceptance a Crane Removal and Disposal Plan. This plan shall contain sufficient detail to allow the Government to determine that the work will be performed in a safe and legal manner as described above, and will identify the proposed disposition of all of the crane materials and components being removed as part of this work.

The crane was removed from service due to significant condition issues revealed in a periodic inspection performed on 02 OCT 2017. The findings of that inspection are provided as Attachment F. However, the crane power systems are still functional, so no‐load operation such as swinging, raising and lowering of the boom, or raising and lowering of the hoist lines may be possible. Operation of the crane under load will not be permitted. If the Contractor wishes to perform no‐load operation of the crane systems to facilitate positioning the crane for removal, they shall first perform their own inspection of the crane using an OSHA competent person, to determine whether such operation can be safely performed. The condition of the crane shall also be considered during preparation of the Crane Removal and Disposal

Plan.
