Vandal-resistant, pre-engineered “green” buildings rival custom construction. From structural concrete floor to finished structure, the entire building is shipped by trailer, lifted onto the prepared site and connected to utilities for on-time completion regardless of the weather. Anti-vandal features include stainless-steel plumbing fixtures, concealed hand dryers, blind-fastened signs and fixtures, 50-year-cycle toilet seats, extra-heavy-duty steel doors, welded-steel vent screens and more. Boast proprietary concrete floors that resist odors forever. Energy-saving features include sinks that use ground water instead of heated water for hand washing (where code allows); hand dryers that use high-volume air instead of heating elements; and automatic lights that use 60%-lower-wattage bulbs and turn off when facility is not in use.
