Dim ond yn ystod y cyfnod a bennir uchod y disgwylir i’r Gorchymyn fod yn weithredol. Er hynny, bydd yn parhau’n ddilys am gyfnod o 18 mis ar y mwyaf rhag ofn y bydd angen ailamserlennu’r gwaith neu wneud gwaith canlyniadol neu waith arall. Bydd hysbysiad am unrhyw newidiadau i’r amseroedd a’r dyddiadau yn cael ei roi cyn gwneud
unrhyw waith a ailamserlennir.
