BOP Program Statement 1060.13 § 4
PHYSICAL CAPACITY COMPUTATION
Square Footage Measurement. The square footage measurement for cells and rooms is
determined by measuring the space from interior wall to interior wall and including the space
occupied by beds, desks, and plumbing fixtures (toilets and sinks, excluding showers). Space
occupied by constructed or permanently affixed items that obstruct the floor space (e.g.,
closets, concrete slabs, etc.) are excluded from the square footage measurement.
The square footage measurement for cubicles is determined by measuring the space from
interior wall to interior wall including the space occupied by beds and desks but excluding
hallways and walkways.
The square footage measurement for multiple occupancy housing areas is determined by
measuring the entire open dorm or living area and includes hallways and walkways.

The calculated square footage measurement for the space is rounded to the nearest whole
number (rounded down if the remainder is .1 to .4; rounded up if it is .5 to .9). For example,
65.2 square feet would round down to 65; 65.7 square feet would round up to 66.
Note: Standard furniture in a cell, room or cubicle includes a shared desk, a double bunk and
two lockers for typical double occupancy. If denoted as single occupancy, the room will
include a desk, a single bunk, and one locker.
Total DFCL Capacity. Total DFCL Capacity is the Physical Capacity of Special Housing
(Section 1 on the BP-A1140) plus Permanent Housing (Section 2 on the BP-A1140). The
Sentry Reporting Unit on the BP-A1140 will denote the unique mission being documented.
Examples include General Population, Residential Drug Abuse Program (RDAP), Satellite
Camp, Jail, Mental Health, etc.
In some specialized self-contained DFCLs, AD/DS housing is located within the same
housing unit. In these cases, institutions will ensure the administrative cells are counted
separately from general housing.
DFCL Physical Capacity. The computation of Physical Capacity for each DFCL is the
Total Capacity less hospital/infirmary and detention/segregation space.
The Physical Capacity for cells, rooms, and cubicles is ordinarily based on double
occupancy, unless there is a programmatic and/or security reason for single occupancy. All
single occupancy housing types must be specifically documented within the housing type
column on the BP-A1140. In the absence of a single occupancy note, all will be assumed
double occupancy.
For multiple occupancy housing, the Physical Capacity is ordinarily based on the total square
footage of the room divided by 60 square feet and then rounded to the nearest whole number.
If the total number of beds is an odd number, then consistent with double occupancy the
number is increased to the next even number. If there is a programmatic and/or security
reason for the odd number, it must be clarified on the BP-A1140 form.
These latter spaces are reported in Section 2, Permanent Housing, of the BP-A1140, Physical
Capacity Computation form. Cells, rooms, and cubicles should be reported separately from
multi-occupancy spaces and then all beds are added together. The total number constitutes
the total Physical Capacity for the DFCL.
Rationales for deviating from double occupancy and/or the square footage capacity
calculation must be documented on the BP-A1140, Physical Capacity Computation form.

Medical Referral Centers (MRCs). The MRC mission requires more specificity to
compute the Physical Capacity of medical and mental health care units than using square
footage alone.
For example, more space may be needed for necessary staff activities, hospital equipment,
special treatment needs, etc. Since these reasons may vary considerably, each medical unit
must be evaluated separately. Additionally, the amount of space per inmate need not be
consistent throughout a unit. For example, the same size room might be rated for one inmate
if used for intensive care, two inmates if used for inpatient care, and three inmates if used for
chronic (nursing home) care.
MRCs will use the Physical Capacity standard referenced in this program statement as a
baseline to calculate individual DFCLs. Then, in consultation with the Warden, Regional
Director, and Health Services Division Assistant Director, the final Physical Capacity for
each MRC DFCL will be established.
MRC’s health care Physical Capacity will be reported for only two categories:
Medical
Mental Health
However, multiple Medical or Mental Health DFCLs may be appropriate, based on the
specific missions of an MRC. For example, the following DFCLs may exist: Dementia Care,
Hospice, Forensic Study, Competency, Restoration, etc. Additionally, there may be more than
one Medical or Mental Health Unit in an MRC but, as noted above, if the separation is based
on a specialized unit, it should be identified accordingly.
MRC beds necessary to support the mission but not available for direct admissions (e.g.,
suicide watch, seclusion, recovery, etc.) will be included in Part 1 Special Housing of the BP-A1140 Physical Capacity Computation form.
The Designation and Sentence Computation Center (DSCC) will utilize Physical Capacity
for designation purposes. The projected population, available capacity, crowding levels, and
population balance, along with other factors related to the individual, such as security and
care levels, central inmate monitoring (CIM) and Security Threat Group (STG) concerns,
distance from residence, time remaining to serve, judicial recommendations, and
programming needs will also impact the designation decision.
