human activity and spatial variety with graceful proportion, as well as
the selection of materials with compatible textures and colors. See
Section 23, Acoustics, for specific guidance on acoustics for
architectural spaces and building mechanical systems.
4.3.1
Layouts and Function. Building and departmental floor plan
layouts should be simple and functional. Avoid layouts that decrease
medical functional efficiencies. Locate permanent plan elements such as
mechanical shafts, stairways, and utility rooms to minimize their impact
on functional use areas or future expansion of critical areas.
4.3.2
Program for Design. Use the TMA/DMFO-approved Program for
Design (PFD) to allocate space assigned to a proposed facility.
Modifications must be approved by TMA/DMFO.
4.3.3
Functional Planning and Future Expansion. Relocation of
departments having least first-cost is a valuable mechanism for
accommodating change. Expansion of expensive existing departments can
often be coupled with relocation of lower cost functions. Placing
departments on outside walls with adjacent site space available for
expansion also adds future flexibility. Open plans, where feasible, allow
easy departmental change. Avoid floor plans that encircle a department
with permanent corridors, stairs, mechanical rooms, or other building
elements difficult to relocate. Reference Section 3, Site Development,
paragraph 3.10.
4.3.3.1
Pursue the grouping of functional elements in accordance with
the following objectives. Where difficulties arise in the mutual
accommodation of all of the following objectives, the objective stated in
subparagraph 4.3.3.1.1 below shall be given priority.
4.3.3.1.1
Where appropriate, combine elements on the basis of functional
adjacency requirements to facilitate better functional flow and reduced
operating and staff costs.
4.3.3.1.2
Combine departments and functions with similar fire code
requirements where feasible. For example, the assembly of all outpatient
clinical elements which do not serve nonambulatory patients can be
constructed to a lower cost as a "business occupancy" rather than the
higher cost of a "health care occupancy".
4.3.3.1.3
Combine elements with similar electrical, mechanical and
structural requirements to facilitate savings in construction costs.
4.3.3.2
Place soft-functional areas (areas having minimal amounts of
plumbing, special finishes, special mechanical features and special power
demands) between hard-functional areas (areas having appreciable amounts
of plumbing, special finishes, special mechanical features and special
power demands) to permit future growth of the hard-functional areas by
relocation of the less costly soft-functional areas.
4.3.3.3
Assure column-free functional areas where possible. Provide
vertical column compatibility in multi-story facilities. Review Section
6, Seismic Design, for seismic considerations.
