Mae darparu’r cynllun drwy’r Model Buddsoddi Cydfuddiannol (MIM) yn cynnig y cyfle gorau i gwblhau’r cynllun mor gyflym â phosibl.   O dan y MIM, ni fydd Llywodraeth Cymru yn dechrau gwneud Taliadau Gwasanaeth Blynyddol tan i’r gwasanaethau ddechrau.  Mae hyn yn cymell y contractwr i ddarparu’r rhaglen ar amser gan gadw at y gyllideb.  Bydd strwythur yr MIM hefyd yn sicrhau bod yr ystod llawn o fanteision cymunedol ac economaidd yn cael eu cyflawni gan y cynllun cyn i Lywodraeth Cymru ddechrau gwneud Taliadau Gwasanaeth Blynyddol, gan ganiatáu i gyllidebau gael eu blaenoriaethu mewn mannau eraill.
Delivering the scheme using the Mutual Investment Model (MIM) provides the best opportunity to complete the scheme as quickly as possible. Under the MIM, Welsh Government will not start making Annual Service Payments until the services are operational. This incentivises the contractor to deliver to programme on time and to budget. The structure of the MIM will also ensure that the full range of community and economic benefits are delivered by the scheme before Welsh Government begins making Annual Service Payments, allowing budgets to be prioritised elsewhere.
