The following criteria needs to be addressed when designing density driven records box storage systems:

• Storage volume and warehouse layout: ceiling height, dock doors, exit doors, office area, and column locations? Temporary or permanent location?
• What are your needs today and tomorrow? What type of storage expansion phasing will meet your needs?
• Type of storage: record archive boxes, open files, medical files, architectural plans, digital media
• Storage & retrieval: file management software, shipping & receiving operations, number of employees, order picking carts & ladders, scanners, RFID?
• Vertical Reciprocating Conveyors (VRC): material elevators, conveyors, stairs to access upper levels, and other equipment involved in storage systems.
• Sprinkler system: overhead and in-rack sprinklers?
• Energy efficient lighting: T5, T8, light timers, automatic sensory lighting?

Catwalk systems maximize warehouse storage space and create additional floor levels that can be accessed by employees without using powered equipment such as stand up orderpickers and forklifts. A catwalk system can be made from heavy duty industrial shelving such as boltless shelving.

Files that have time sensitive requirements, such as those in the medical industry, are typically stored in an open shelf file system where each file can be accessed individually. Files can be managed using a terminal digit system.
