Column three of the WH 347 is the work classification column. The work classifications column list categories that describe the actual work performed by each laborer or mechanic. Consult the contract specifications for the classification and minimum wage schedule. If additional classifications are required, consult with the Contracting Officer or an Agency representative.

It is essential that it is correct because it determines the total package amount that can be paid to a worker for a specific type of work performed on the job site. The prevailing wage rates vary by region, so make sure you're using the correct rates for that specific construction project. To determine the current rates, you must first determine the type and location of the project.

Once you have the rates, you must choose a trade classification. This is evident when you examine what each individual did on the job site each day. Once you understand what they've done and can locate the appropriate trade classification, you must request it, which is a separate procedure. Once the trade class has been determined for that individual, you must ensure that they have been paid the minimum total package amount for the work that they were performing on the job site. Restitution is required otherwise.
