Future standard plans

Check here for upcoming approved standard plans.

Future Standard Plans are those approved for publication, that are awaiting the next installment of a revision package (an annual cycle) before they can be referenced from a contract. We post them on the Standard Plans page as they become approved.

A Future Standard Plan may be included in a forthcoming contract as a detail sheet.
