Aerial thermal mapping of your campus every few years will reveal leaks in all types of systems, like steam and condensate return lines, hot water lines, chilled water lines, supply water mains, distribution pipes, storm water drains, building heat loss and moisture leaks into your roofs.Aerial photographs should be taken every few years as well. They are inexpensive and can be a great asset when discussing future building additions with management, planning utility repairs and improvements, drawing CADs of the facilities and for uses as simple and handy as 'showing' outside contractors where not to park.
