Prototype R7 Boom Crane Assembly

SECTION 1.0 – ADMINISTRATIVE INFORMATION

1.1 Introduction

The United States Marine Corps (USMC) is currently looking to improve the coating system used on the R7 crane installation. The R7 crane installation is on the external of the Assault Amphibious Vehicle (AAV) Recovery Variant (R7) and is staged in a highly corrosive environment. The physical geometry of the primary boom assembly and telescoping boom assembly, makes it extremely difficult to refurbish (i.e. abrasively blast and re-coat). Typically, when the AAV R7 comes in with a corroded crane installation, the standard practice is to remove it, disassemble, identify items that can be salvaged and to produce a new primary boom assembly and telescoping boom assembly. This process adds significant cost to the process and can be substantially reduced if a process can be identified to re-coat the crane assembly.

This statement of work will describe the necessary tasks required to provide one fully refurbished boom assembly, in accordance with drawing 7010547, with the exception of changes made as described in Section 1.3.

1.2 Government Furnished Equipment (GFE)

As a part of the refurbishment effort, the selected vendor will be provided the following government furnished equipment (GFE), with the federal condition code of the item listed . The description of federal condition codes is found in the referenced document under section 6.0. The selected vendor shall provide all other items, required to perform the necessary work and deliver the refurbished boom assembly (DWG 7010547), which are not listed here or are found to be missing from either the boom assembly (DWG 7010547) or any of the lower level assemblies.

Qty. 2 – Boom Assembly (DWG 7010547) – Condition Code F (Unserviceable/Reparable). The assembly does not include the following items, to be provided by the Naval Surface Warfare Center Carderock Division (NSWCCD), in the form of a prototype with the equivalent form, fit and function of the original item:

Item 8, Qty 1 – Telescope Pin, Front – DWG 5424071

Item 11, Qty 1 – Telescope Pin, Rear - DWG 5424072

Item 20, Qty 1 - Single Telescoping Cylinder Assembly - DWG 5424081

Item 23, Qty 1 - Lift Support Pin - DWG 5424080

1.3 Work Statement

The selected vendor shall perform the work described in this section. Outsourcing any part of the described work is acceptable. The following process shall be followed:
