Sample drawings

[hollandhvac]

My HVAC contractor is asking for sample drawings
They like to see a sample of a balancing drawing with the indication of duct size, air flow, Air speed, pressure drop.
Also a D& ID drawing they would like an example of.
Can anybody upload a PDF sample of this type of drawing?

Thanks

Does the contractor have a set of contract documents with this information on them already? How did he prepare his bid?
