1. INTRODUCTION. The 509th MXS/MXMT requires the construction, fabrication, delivery, assembly, and utility hook up of 1 set of comprehensive modular B-2 maintenance work stands, that will consist of 2 stand modules, 1 for each wing.

for use in phase inspection of the wing areas. The design will incorporate features described in Appendix 1, and provide access to the wing areas of the aircraft comparable to the stand currently in use. Contractor shall provide the complete turn-key, fabrication, inspection, testing, documentation, training, delivery, tools, equipment installation, work stand assembly, labor, and other incidentals necessary to provide such work stands in accordance with this statement of work (SOW).

1.1 Stand Design. The stand design shall be based on and compliant with work requirements in the maintenance docks at Whiteman AFB, Missouri.

1.2 Scope. The contractor shall provide for the, fabrication, delivery, and assembly, of wing stand set. The work stand set are to each facilitate one aircraft dock and be capable of being moved and used in any of the other aircraft docks at Whiteman AFB where phase inspection maintenance is required. Contractor shall provide complete fabrication, inspection, testing, documentation, training, delivery, tools, installation/assembly, labor and other incidentals necessary to make the work stand set operational and usable. The proposed work stand set will meet as a minimum the requirements of similar equipment as established for the B-2 PDM contract as well as the design used on the SOW, with any mods, for the use of future procurements if required.

1.3 Impact Statement. If existing maintenance support stands used for phase maintenance are not supplemented with stands with an improved design Whiteman AFB B-2 phase inspection process will continue to be less efficient and less productive the than it could be. In addition, these maintenance stands will be safer, and increase production, eliminate other aerospace generation equipment due to the panel storage configured within the new design and extend out further to access other inspected areas where we currently need other stands to access. Exposure to worn out or inappropriately configured stands, and poor design can cause low productivity.

2. Requirements. Contractor shall provide all necessary qualified personnel, management, non-personal administrative and technical services, materials and contractor facilities in support of the requirements of this SOW.

2.1 Task Description. The contractor shall provide turnkey fabrication, construction, and delivery of one set of B-2 Phase wing maintenance stands and delivered to Whiteman AFB, as well as any design modifications on the contract, and any modifications in design required by this SOW or work stand specification. The U.S. Government shall own any changes to the stand design.

2.1.1 Program Management. The contractor shall provide a program plan describing work task, schedule, cost and deliverables. A program kickoff meeting shall be conducted after task is awarded and prior to delivery of the program plan to ensure all parties fully understand requirements and are ready to proceed. Additionally, a Technical Interchange Meeting (TIM) shall be convened at a suitable time to be determined by the contracting officer’s Technical Representative (COTR), the contractor shall prepare the agenda and minutes of the TIM as required. The contractor shall also prepare and deliver monthly status reports.

Informal communication via face-to-face, phone, and e-mail throughout the project is encouraged.

2.1.2 Baseline Requirements. The contractor shall provide complete fabrication, inspection, testing, documentation, training, delivery, tools, installation, labor, and other incidentals necessary in accordance with this SOW. The contractor shall take given dimensions and other information necessary to incorporate into a drawing and data package that will allow the contractor to manufacture and assemble one set of maintenance work stands and ensure the completed stands fit the aircraft in a manner that allows personnel to perform all desired maintenance operations safely and efficiently, and effectively incorporates functions specified herein.

2.1.3 The entire B-2 work stand set will be fully functional upon completion of installation. All work stand components shall be capable of a total one hour set-up time by 4 aircraft workers

2.1.4 Fabrication. The contractor shall procure the equipment and hardware necessary to support the fabrication of the B-2 work stand set. All equipment and hardware shall be off the shelf items to the fullest extent possible.

Contractor shall perform all fabrication activities at the contractor location for assembly at Whiteman AFB.

2.1.5 Shipment. The contractor is responsible for work stand preservation, packaging, loading, and shipping to Whiteman AFB. Contractor shall coordinate delivery arrival dates with Whiteman AFB for approval. The entire work stand should be shipped and arrive within a three day time period.

Whiteman AFB will not provide storage for intermittently shipped equipment outside of the three day window.

2.2 Assembly

2.2.1 General Assembly. Safety equipment shall be used during work stand assembly and must be in working condition. Where items of assembly cannot be assembled properly as a result of errors in fabrication or deformation due to handling or transportation, remediation shall be the responsibility of the contractor. Contractor shall immediately report the discovery to the ACO.

Repair method must have prior approval by the COTR before any work is performed. The straightening of steel base frames, tubing, angles, connecting devices, casters, or other components shall be done by methods approved by the industry.
