Condom army to be dropped

Though I believe that the condom army is better than the slabs with the ice I am going to have to go with the latter. This is because I cannot expect the cleaners at the hospital to pick up each individual one to clean underneath and place them back to the exact position there are intended. I thought if I prehaps place them on plinths that were on wheels but the work would still have be lifted and cleaned.
The slabs would be displayed as a relief and easily dusted down.
