I need to hire someone to perform sprinkler hydraulic calculations.
The individual should be familiar with NFPA 13 (2007 and up), with demonstrable experience with performing hydraulic calculations.
If interested, send resume, 3 samples of previous calculations performed, and name and edition/year of current software you use. Samples should be from that software. You must also have access to AutoCAD. Let me know what year of AutoCAD you use.
And, answer these three questions.
1. what is the minimum pressure required at each sprinkler head (in PSI), per NFPA 13.
2. Suggest three changes you can make to the system, if a sprinkler head doesn't meet the minimum pressure required.
3. What are the components of a preaction system, and provide a brief description on how it works.
I need at least five calcs done, at $40 per calc. Also, need quick turn around.
