I’m also confused about this particular bid.
When I mention cranes as a possibility I usually present it as just that, a possibility- the price is set regardless, as not using a crane will require equal parts additional labor. Sometimes the crane operator we contract out might not be able to reach the tree, sometimes you got a hot shot climber who can wham bam it, things happen.
For the same logic I don’t get into the weeds about how a removal is going to be done- rigged or not, speed lined, felled a certain way- I say we will avoid damage to XYZ, and sometimes put in work plans for the crew but always as ‘the arborist may elect to fell the tree into the woods” etc.
