Appreciate it if anyone can direct me to a
website where I can find samples of
prequalification specifications for selecting
qualified arboriculture contractors.

It be great if I can find references to:
1. Requirements for certification.
2. Minimum number of tree working crews.
3. Standards in mechanization.
4. Standards in tree works safety.

Any input would be appreciated.

For cert stds and safety see www.isa-arbor.com

re mechanization and number of crews, that depends on the contract. I've performed several even though I have no crew and little mech.
