MIL-HDBK-1191
TRANSPORTATION AND MATERIALS HANDLING SYSTEMS
SECTION 17:
GENERAL. This section provides guidance for the study, selection
17.1
and design of transportation and material handling systems and establishes
requirements for elevators, dumbwaiters, pneumatic tube systems, material
delivery equipment, pedestrian traffic, service cart systems, and gravity
chute return systems for linen and trash in military healthcare facilities.
The section is not intended to cover all aspects of transportation analysis or
design, but rather to act as a standard for use by qualified medical transport
consultants (MTC).
17.1.1
Scope. This section applies to horizontal and vertical
circulation within healthcare facilities, and the transportation devices,
equipment and methodologies required for efficient, cost effective and timely
movement of people, equipment, materials, and related materials management
functions. Program factors for patient beds, healthcare procedures and
departmental workloads should be provided by the user service and should be
utilized in computing traffic demand loads. Select vertical transportation on
the basis of acceptable response and waiting time intervals. Calculate the
intervals from an analysis of elevator car speed, traffic transfer time, door
operation cycle and other applicable system capacity factors.
17.1.2
Waste Management. Section 18, Waste Management, of this Military
Handbook is the primary reference for medical facility waste definition,
handling, and disposal; closely coordinate transportation systems studies and
design with the contents of that Section.
17.1.3
Construction Phasing. Where phased construction is necessary,
provide studies and designs for each phase. Provide design for transport
system elements not required until later stages to allow for phased
installation. Phased installation shall be accomplished with a minimum of
rework and without major disruptions to the facility's operations. Give
specific consideration to placement of transport devices for present functions
and for possible future facility modification.
17.1.4
Addition and Alteration Projects. These criteria are intended
primarily for new construction, however addition and alteration projects will
meet these criteria to the extent practicable. When additional elevator banks
are to be provided for facility additions, they must be located along the same
major circulation paths that serve the existing elevators, where feasible. See
also Paragraph 17.5.3.6.
17.1.5
Area Allocations. Base the floor area requirements for
transportation equipment on the specific equipment included in the
transportation analysis. The area allocated for such conveyances is part of
the central circulation factor. Additional area for penthouses or other
transportation equipment rooms will be considered part of the mechanical space
allotment. Consider shaft space as part of the circulation allotment. If the
transportation analysis justifies a system requiring more than the assigned
area, additional space for elevator lobbies, cart queuing space, shafts and
penthouses must be identified early in the Concept Design phase. The designer
will submit justification for deviations from criteria, and illustrate how
additional area allowances would increase operational efficiency, improve
service to patients, or reduce costs. Systems not providing high utilization
