Voltage Drop

There is no NEC requirement for voltage drop compensation so there is no code issue. NYC might have a VD requirement if applicable.

No, but there is an Energy Code that most designs have to abide by as well. Also, isn't there a thing in the NEC about 5% maximum voltage drop? Just saying.

I agree with everyone's opinion. You can't estimate a job that has been "engineered" incorrectly. It is one thing if something arises during construction but estimating a plan set that is wrong is like a cascading set of issues.

Do the plans go through city plan check review prior to estimation? The plan checker might flag the issues for you.

But a good estimator would have caught the discrepancy while in the process of bidding and sent an RFI for clarification. In Florida the plan reviewers are not liable for things they miss. (imagine that)

In 210 its only a suggestion. In 215 it's only a suggestion. In other articles its a requirement.

In 210 and 215 they are informational notes which is not an enforceable thing - it is just a suggestion. There may be other articles for specific circumstances - those would be required.

Some other code possibly could have a max VD requirement or even manufacturer specs for specific equipment might have some limitations often that comes with no performance warranty should you disregard this and not so much anything going to come from code officials.
