are typical and taken from construction cost indices. They
may very depending on local or special factors.
In most cases, a visual inspection by a knowledge-
g.
able surveyor, can result in a numerical value being
assigned to the percentage acceptable for each element.
Those elements that are entirely acceptable are assigned a
value, or "feasibility factor" of 100. Those that require
modifications are given lower numbers as are judged
appropriate. These are entered in column 3.
h.
Column 4 provides an "Actual Value Factor". It is
determined by multiplying columns 2 and 3, and dividing
by 100. The total of all actual value factors produces an
overall value factor which offers a useful yardstick in
approximating the relative worth of an existing facility
compared to a new structure. One rule of thumb is that if
the overall value factor is over 50% it would be reasonable
to pursue in greater detail the economic feasibility of con-
verting its space. Simplified, that means the existing facil-
ity in its present state is worth half that of a new physical
facility. A sample evaluation is shown on the chart.
If the proposed facility has passed this test of accept-
i.
ability, the next step is to establish preliminary cost esti-
mates for bringing the building to a state of usefulness for
its new function. This usually requires the preparation of
conceptual design drawings and an analysis of the useful-
ness of the converted space.
Found space is frequently a solution to housing

expanded Arts and Crafts Programs in satellite centers.
For efficient space and maintenance management, a rea-
sonably large cluster of activities should be incorporated
together into one location. From the list of activities given
in Chapter 3 a separation of activities into three subsec-
tions would be the maximum recommended: Woodwork-
ing Activities, Photography, and General Arts and Crafts.
k. The criteria given in Chapter 3 of this guide is
based upon a 20,650 square foot Arts and Crafts Center
which was selected only for illustrative purposes. Experi-
ence has shown that if a building is converted to another
use, it will usually have to be larger than a building
designed specifically for that use, because of inherent
problems of flexibility and structural limitations. These
factors must be considered when evaluating a structure
for a particular use.

Following the preparation of a program, a concep-
tual design response to it, and a preliminary cost estimate,
some valid judgments can be made on the advisability of
converting space. Obviously, if the cost of the conversions
