<< The scenario: Building is all concrete, steel and rebar, and handheld
 operation is desired from anywhere to anywhere in the building. VHF on a
 simplex channel is about the only way we can go.
 My solution: A combination of passive radiators, and Radi-ax. The passive
 radiators on each of the housing units, and Radi-ax running through the
 floors and ceilings in Administration areas.  >>

       Is Radi-Ax a feedline? I'm not familiar with it. The way most indoor 
systems are done is to use 'leaky' coax; that is, coax with the shield cut 
away a lot. The inner conductor can then radiate. This is popular in tunnels 
as well as buildings.
