I have tried numerous ways of working with the data trying to get a surface or contours from it, to supplement our ground run survey for roads, creek channel cross sections, etc. This is at the request of our client. The lidar information is in an *.adf format if I remember correctly.

Sounds like you are a victim of ESRI"s push to fence LiDAR data off into their proprietary format.
ADF is an abomination foisted on the unsuspecting who attend ESRI training without knowing anything about LiDAR, who drink the kool aid and then spread the disease.
The open source LAS format which ESRI is trying to bury doesn't have any of these issues.

Well actually you don't have to.

I am a power user of Carlson Point Cloud and have a direct line to the lead programmer. I use it for the big stuff. I have processed aerial with Carlson. I prefer Carlson for the extractions since my F2F codes integrate so well. One trick with the F2F codes, take all your normal Topo codes and create a second code for each that drops them onto a non-topo layer. In the field, you can locate a fence or building corner with a good Z. In the cloud, you are lucky when you can line it up.
I have Civil3d, but disregarded it when it could only take a 10m point cloud / 20m with ReCap conversion. Has AutoDesk increased their amount? I paused at 2014 as I have great hope that IntelliCAD will be there for me when I am ready to upgrade CAD.
I used to process GeoTiffs through QGIS to get contours.
Let me know if I can be of any help.
Thanks for the replies everyone. I'm on vacation this week, and have been under the weather the past few days, and away from the computer. I'll follow up with this more tomorrow.
In demoing the Carlson Civil Suite, I saw some pretty nice tools in there for surfacing that I did not see in my Carlson Survey 2016 OEM version.
I do know that I have to be able to do this more efficiently in the future. I'm sure I'll have more questions and comments tomorrow when I can actually get to my laptop.
Thanks again everyone,
Jimmy
I am currently frustrated with Civil 3D. Playing with Trimble Business Centre HCE, base version is free to use, and enquiring about licence options. It can handle shape files, las files easily with import or drag and drop. So easy, why have we run round and round inside the wheel with civil 3d?
The workflow is ok in Civil 3d 2016 and 2017, and the ability to use Lidar file in Civil 3D occasionaly was one of the few good features.
