Who says clients don't pay for modeling?

Yes, Kinko's can do 24 x 36

Jason, if the lot is an issue there are ways to get the terrain
off the surveys or GPS or the sat photos. See my earlier posting about terragen and all the ref's about terrain data.

I purchased a 13' construction rod so that I can place it in the street and then using the disto on the ground at the front corner of the house shoot the laser to the rod and that gives me the elevation difference. do the same at the rest of the corners of the house and then at the back of the lot or other places as the terrain changes and you have a basic contour map to plot in.

If it's more that 13' it'll probably be on the survey.

You can also have an engineering firm do a site survey which is more detailed than a "settlement" survey. I had mine done for $450 here in DC area. Probably cheaper elsewhere.

Just bill the customer for this service or else model the as-built on a flat terrain pad with enough elevation changes to justify the stairs to the house (front,back,side). If they want better they can pay for it.
