What are mix pay factors assigned to?

Mix pay factors are specifically assigned to each Pay Factor Level (PWL value) as it determines the payment adjustments for the asphalt or concrete mix based on the quality of the material incorporated into the project. The PWL values reflect how closely the actual mix properties achieved meet the specified requirements set forth in the project specifications. A higher PWL indicates that the material quality meets or exceeds the specifications, which can lead to higher compensation. This system is essential for ensuring that contractors are incentivized to provide higher quality materials since the payment they receive is directly linked to the performance and quality of the mix used in construction. Consequently, the correct assignment of mix pay factors to PWL values ensures that the financial implications align with the quality outcomes of the construction materials used in a project.
