I have a freelance design "firm." It is myself and an FPE. He is currently using hydracad because that is what he was on prior to me hiring him, and I needed him productive at day one. I also have hydracad as well as AutoSprink myself.
Since you will be a design only "firm," your profits will hinge on design production. As an installation contractor, you can over run on design hours and still come out OK on the job since design is a very small portion of the cost of most projects. However, if design is your product, you need to be the fastest and the most accurate you can be.
HydraCAD is very nice for an autocad based system. It is a good package and very powerful for fire sprinkler work. It has a great calc program (I think you just need an hour or 2 of fine tuning on the training and you will see it works great). The listing program has something to be desired, but is still very good. The text cleanup on hydracad is the best in the industry. The new SMART tools routines in hydracad are also very impressive.
However, with all of the benefits of HydraCAD, AutoSprink still far surpasses it for production and accuracy in my opinion. I can also take a hydracad, omnicadd or sprinkcad file and convert it to Autosprink fairly quickly. When my employee needs me to pick up on a project or help on some calculation issues, I often find it easier and quicker to convert to AutoSprink instead of using HydraCALC. It is really that fast.
Now, as a startup company, you need to look at software costs. A new license of AutoCAD will run about $3600. I just bought one from HydraCAD. A new version of HydraCAD will run about $3000. You then have the option of upgrades only, or unlimited support. The upgrades only is $80/month and upgrades + unlimited support is $160 / month. I choose the $80 route because I rarely need tech support and it is cheaper for me to pay the $100/hr that is charged for HydraCAD tech support. I think that I may have paid $200 in the last 5 years for HCAD tech support.
AutoSprink is going to run about $4500 +/- for the initial purchase. You then have a yearly fee of $3300 or so to renew the license. They provide unlimited tech support and updates. There is not an option for updates only. I have the full blown Platinum Version with all of the bells and whistles, so that is my pricing. You still need to buy AutoCAD, so those costs are the same. I say you need AutoCAD because there are just some things you need it for (binding xrefs, basic cleanup, etc). So, AutoSprink is about $1500 more initially and anywhere from $1500 - $2500 extra per year. But, I can guarantee that you will make up the difference in the first month or so by an increase in production. However, you MUST go to the initial autosprink training for 1 week. You would be a fool to try and self teach AutoSprink. There are some many things it can do and all of its little nuances, you really need the training. They do not have a decent manual because they want people to do the training. It would be a very difficult program to learn on your own. I honestly don't recall the training prices, but it is probably on their website, or you can call to find out.
I have no financial interest in you purchasing AutoSprink or Hydracad. The things above are just my opinions from using the programs for a couple of years.
Good luck in whatever you decide to do. You can go to
and read the AutoSprink forums to see what people are saying on there about the program.
I don't know if this site is the best for providing you tech support for HydraCAD or Autosprink. However, if you go to the AutoSprink forums, you will see postings by me all over it. You can get my email from there and I will be able to provide you with further answers on both programs if you need.
