Payment
Payment Item number Item Description Unit Measure 430-5AA-BCD Endwalls EA 570-1-A Performance Turf SY See the BOE and Specification 430 for additional information on payment, pay item use and compensation. Example Position is set by the intersection of the front slope and Point A where this intersection falls outside the clear zone. Where the front slope and Point A intersects inside the clear zone, the endwall is positioned so the Station/Offset Location is at the clear zone limit.
The front slope is transitioned to the endwall as shown in Index 430-001 .
