[CANUFNET] tree protection

[Burleton, Mark via CANUFNET]

As a comment to Michael's last paragraph and to this conversation stream.  

Has anybody, tried or adopted, the process laid out in Tree AZ  by Jeremy Barrell ? 

Tree AZ is a common sense approach to the communication process, which can be adapted to suit particular circumstances. (free to use as a template I believe) 
The process is inclusive with the architects, engineers, and the constructors. There will be the unforeseen , which I am sure we all have faced on construction sites.
An example,  a telephone line being re-routed through  CRZ , without the project manager, arborist, or engineers or anyone else being aware of the work ; the day after the fencing was taken down. 
I'm sure we can all relate to this 

Tree AZ helps myself and the team to triage and importantly work together..... Learning to listen, being polite, being professional and being pragmatic helps.  

Sometimes ( not always) spending a little time with constructors to show them why you're asking for the TPZ or CRZ, does help. 

My 10 cents Mark

Some interesting thoughts here.

Those little dots; most arborists I know do not have the equipment or expertise to to locate trees with any precision, nor the GIS software to plot them.  If an arborist is using a plan created by a surveyor than surely the arborist must locate and plot not the tree, but the entire trunk diameter or root collar/trunk flare with the same accuracy and precision.

Certified tree expert; what exactly is this?  ISA Certified Arborist? 
Self-taught?  College-educated with an emphasis on climbing?  Two days of TRAQ?

Does a certified tree expert mean somebody with the knowledge, training and experience to perform the work at an expert level?  In the case of tree preservation reports this would surely mean that the tree expert would require not only education about trees but also construction techniques etc.  Further how can the arborist be expected to create a TPP without speaking with the architect, landscape architect, constructor and excavator?
