There are quite a few civil engineers on this forum AFAIK.
For objects, check Objects Online (
http://www.objectsonline.com/),
as one of the more comprehensive sites for GDL.
There objects/API's for generating survey bounderies there as well, some may be metric (NZ)
Check the archives for more references to "Survey"
Hope this helps some.
