B. The Availability’s modernization scope will include a significant amount of work across multiple trades and spaces. 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, and ventilation work if needed. Both the prime contractor and AIT contractors will execute the structural/industrial work. With the taking down of FODMS, the installation of a temporary fire alarm system and temporary flooding system will be necessary based on requirements of S0570-AC-CCM-010/8010; Industrial Ship Safety Manual for Fire Prevention and Response. Further direction will be provided in the work specification package to define the work split.

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.
