three buildings - one building for reconditioning, one building to isolate the
welding repair operation, and one building for the boiler plant.

facility shall be insulated concrete masonry unit construction with standard
construction and finishes as specified in NAVFAC DM-l. Special acid resisting
finishes and equipment shall be provided as required by operational
requirements. Storage facilities shall be provided for paint, lubricating
oils, and caustic concentrates as described for flammable storage facilities
