WFL Projects with Escalation Factors

This section offers data for projects with an escalation clause. The calculations used in establishing the project baseline index and the monthly index for each project are displayed on the individual page for that project.

How does Fuel/Asphalt Escalation Work? - Stepping through the SCRs

In January, 2011, WFL began reporting monthly average prices for fuel and asphalt by markets. Although historical (pre-2011) data remains under specific projects, new monthly prices are no longer listed there. Instead, users need to reference their contract (see section 109.06) and determine which market is being tracked for their specific contract. Users can continue to view the Base Price Index Calculation by selecting their project from the project list below.
