While there is no specific provision discussing
requirements for record maintenance, there is a paragraph in
the penalties section which mentions punishment for inaccurate
or incomplete information in the monthly record:
Except as otherwise provided in subsection 8, a contractor engaged
on a public work shall forfeit, as a penalty to the public body
on behalf of which the contract has been made and awarded to
the contractor, not less than $20 nor more than $50 for each
calendar day or portion thereof for each workman employed on
the public work for which the contractor or subcontractor willfully
included inaccurate or incomplete information in the monthly
record required to be submitted to the public body pursuant
to subsection 5 of NRS 338.070
