B. The Availability’s modernization scope will include a significant amount of work across multiple trades and spaces. The work will largely consist of CANES HW 1.2, AN/32(V)6, AN/SRQ-4, SSEE Mods, DDG HM&E MOD, ADNS and Removal of Unused MCS Cables. The successful contractor must be able to provide an integrated production schedule that incorporates AIT, 3rd Party contractors, and Government workload. Key trades & efforts include: structural welding, cabling pulling, piping, electrical including fiber optic cabling/connectorization, and ventilation work. Both the prime contractor and AIT contractors will execute the structural/industrial work. Further direction will be provided in the work specification package to define the work split.

C. The Availability’s maintenance requirements are expected to include the following types of work:

Hull Structure

Assessments.

Condition-based repair and replacement of structural decks.

Condition-based repair and replacement of superstructure and deckhouse level decks. This will include thicker deck plating.

Ship Assembly and Support Services

Services are directly related to availability, location, duration, and man-day determination.

Man days can differ by region and whether the availability is performed in a public or private ship repair facility. Services are predominately driven by availability duration with the exception of cleaning and pumping (tanks and bilges), crane, rigging, and temporary refrigeration services which are more ship-specific.
