Re: estimating program
I use Accubid, its a good program. I got a demo of vision's bid manager and liked it too. I like the reports in vision and the fact that it uses "modules" instead of basic assemblies like accubid. The modules ask for the correct components that you are likely to use while doing a takeoff in that particular module. In accubid you have to pick all over the data base to find the components if you want to modify an assembly. Accubids tech support is great. Whatever program you get, I would make sure that you can sort the extension by more than one level such as system, area,phase, etc. You can do this on these. From what I have seen of Jaffe, it only has one level of sorting.
