ABSTRACT
A S far as it concerns us, a retrofit job consists simply ofdesigning a fire sprinkler system for an already existing building. There are plenty of fire sprinkler designers who really prefer to engineer retrofit projects instead of new construction jobs. The task of collecting facts becomes basically field work, which they find easier. Everything you need to know is physically present, right there in front of your nose. Field survey time, however, will be substantial, and there are usually no architectural or other existing dimensioned plans to rely on when you’re at work later, at the drafting board. You will be depending entirely on your own field measurements. Maybe for this reason, I don’t know exactly, there are many more designers who prefer to work on brand new construction projects. Whatever the personal preference, a fire protection designer today will without question be working on retrofit projects from time to time.
