Yes. Offerors may submit an independent response for the specific portion of the requirement they can perform. Component DMWRs and technical information: Please provide the applicable DMWRs for the components, including current revisions and associated drawings/specifications. We also request the latest available scope, component or part list, materials, dimensions and weights, estimated quantities and lot sizes, and existing coatings or contaminants to be removed. Please advise on the process for obtaining any technical documents that require controlled access. Applicable drawings, specifications, DMWRs, and other detailed technical information will be provided during Phase 2, as applicable. Process and acceptance requirements: What cleaning methods, final surface condition/profile, inspection and acceptance standards, and contractor qualifications apply specifically to the abrasive-cleaning work?

Inspection and Acceptance Standards: Upon completion of the Abrasive Cleaning process, parts/material shall be free of scale, paint, and corrosion products. The contractor shall ensure that parts are free of warpage, distortion, and excessive material removal and that they are free of dust, silt, powder, and any other contamination. Upon receipt from the contractor, the Government will conduct a 100 percent inspection to verify that the parts and materials meet the applicable requirements.
