In order for the AnchorSpan to meet the requirements of its engineering calculations and be certifiable
for 70 mph winds under the ASCE Code modified for temporary use, it must be constructed properly
with the specified minimum number of beams for the given span. It must be properly cross-cabled,
and anchoring should be sufficient to withstand vertical and horizontal forces equal to, or greater than,
those shown above on each baseplate plus an appropriate safety factor. When properly constructed,
each beam can support 2 lbs per square foot (span times bay width) of additional dead weight.
