  35. BOE Advice • If you don’t see a pay item that you need, please ask. • Existing/available Item groups • Request that an item be opened/activated, if needed • Request that we restore an old item/structure, if needed • Verify that old specs/standards are applicable • Request that we create a new item group • Consider requesting a Developmental Specification and Pay Item • Consider a Generic Pay Item
