HVAC product selection is not as easy as it sometimes seems. For sure, the key part of engineering is the KIS principle (Keep It Simple). However, the KID principle (Keep It Defendable) is even more important in today’s litigious construction industry where there are increasingly more demanding codes and standards that apply to integrated building design, construction, operation, and maintenance. One example is the basic selection and installation of life safety dampers that must be cycled periodically to prove they will indeed operate and provide the life safety features the codes require. Engineers and architects who fail to provide integrated design to allow for the maintenance access to life safety dampers may indeed find themselves liable for a loss of property or life occurrences.
