I have used AGTEK from it's inception to around 1997, PAYDIRT and QUEST temporarily around 1998, and INSITE since 1997.
The only time I ever look back with INSITE is to watch the others trying to catch up.
My biggest complaint with AGTEK, back in 1997, was that you had to digitize elevations around a region to make a subgrade. Unless you were creating a region with a "daylight" around the perimeter, this was very tedious. Right off the bat INSITE solved this problem with their "Quick Stack" subgrade method.
I’m assuming that you want to import a curb line to encompass a paving subgrade.
Are there any other subgrades inside the paving area (add’l landscape islands, another building)??
When you import with INSITE, you can assign it a hierarchy number to either supercede or be subordinate to other subgrades. This is especially useful when you have a huge parking lot with a building in the middle that you have already digitized or imported.
As far as Dirtmaster’s experience with ease of importing existing vs. proposed contours, my experience is that both are either usable or totally unusable (with all forms of Earthwork Software). The problem is how the draftsman inputs the info in the original CAD File. If contours (existing or proposed) are represented by broken splines with no elevation values, then manual digitizing is probably your only option. Which if that’s the case, the CAD file was never meant to be calculable and an earthwork takeoff is all that more important (how can an engineer be cognizant of a site’s balance if the math was missing from the design in the first place).
However, if the contours are properly represented by polylines with elevations assigned, INSITE will import into either existing or proposed with equal ease. You can edit elevations to splines after import, but sometimes the number of them makes manually digitizing the better effort vs. return.
I can’t remark on AGTEK, as it’s been a while since I have used it.
I have had such bad experiences with PAYDIRT’s technical support (or more specifically lack thereof) that I consider them the industry standard of a good bad example. Of more concern is the fact that you can digitize or import a job twice and get two substantially different volume reports.
In summary, I just want to be specific that of the list of Software mentioned in this thread, all are not the same.
AGTEK rocks if your primary focus is creating a mass diagram for long sections of highway via X-Section input.
INSITE is my choice for getting a large site development project done as accurately and efficiently as possible.
PAYDIRT is my recommendation if you’re my competitor.
