If you're doing concrete layout, get a Spectra Focus and Layout Pro. Nothing Topcon or any of the other brands offers is even close to the ease of use that setup offers. Where are you located? I might be able to help get you setup with a demo unit if you're in the states.
My experience is most are using Trimble stuff. I have been setting up CAD files for one contractor then they do statekout with a Robot. I agree with Lee, learning the software and setting up the CAD file are the hard part.
Thanks everyone for your input. Thought it would be good to update this thread. I ended up renting a robotic total station for a while. I just couldn't decide which was going to be the right solution for us.
We've gotten a Sokkia IX-505 for a couple months to see how it works out. I just started using it today and it's pretty user friendly. This was my first time using a robot, so its going to take a bit of time to decide what features i like or dislike.
I've prepared all the data for the foundation footings and will start layout of it tomorrow. I'll post a few updates later on how it works out.
I would look into retro reflective targets also they are handy if your setting up a lot of times in one area. Also we have 3 IX’s watch your tilt and collimanation and backsight when there are temperature changes
Me personally if all your GPS and data collectors are Top Con then I'd stick with Top Con. I am a Trimble user and would not care to have trimble Gps, Leica total station and a Top Con controller.
I think getting into the layout aspect I think there's more behind setting some building corners and calling it a day. If I supply you some control point coordinates and you lay out your building and then find out its 0.5' over the building minimum set back after you have a footing or more built, you will be taking on a lot of liability. You would be surprised that kind of thing happens or a drawing has property lines drawn n-s, e-w and the property is a parallelogram.
So I guess what I'm getting at is weigh your options. laying out a building isn't just stake some coordinates and be able to say that's where the auto cad had it, and is it worth paying a surveyor to set up the building then handing it over to you and putting that liability on the surveyor that he did his checks and balances.
