. SECTION II DEFINITIONS AND ABBREVIATIONS GENERAL This section presents the definitions and abbreviations used throughout the three volumes of the F&SR Plan. DEFINITIONS BOD - FOD - These expressions are utilized to indicate the actual calendar date or a relative GO date when a facility will be required for occupancy. ''BOD" (Beneficial Occupancy Date) is defined as the date when construction of a facility will reach a stage that will permit concurrent construction or installation of equipment by both the construc tion contractor and the using agency or its agent. "FOD" (Full Occupancy Date) is defined as the date when the construction of the facility will reach a stage that it may be used for its intended purposes with relatively little interference, restriction or inconvenience from the completion activities of the construction contractor. If a facility is scheduled for participation in more than one event, the FOD is based upon the earliest scheduled requirement. An exception is in the scheduling of planned facilities for Nuclear Operational System Test (NOST) participation. Established design, procurement and construction schedules will not be adjusted to accommodate NOST participation, except for the facilities at Midway. Certain facilities at MidWay are required specifically for NOST participation and have an FOD based on this requirement. If a facility is incomplete on the date of a NOST, an alternate facility may be used. F&S No. - Facilities and Support number (F&S No.) is a five-digit identification number assigned to a project or facility. The first twodigits reflect the location and intended use of the facility. The exception being the off-island facilities, whereby the first two-digits reflect the location only. Table 2-1 lists a summary of these digits. The last three digits are assigned in line item sequence for each location and intended use. Once a F&S No. has been assigned to a facility, it will not be reassigned to another facility or project. However, an assigned F&S No. may become inactive and subsequently be deleted (the facility requirement was rescinded prior to any effort expended), cancelled (the facility requirement was rescindedafter some effort was expended) or transferred(the facility requirement was includedas partofanother project or facility whichhadanassigned F&SNo.).
