a MOD has unrestricted rights under the contract to request variations to the contract. Minor changes such as office reconfigurations or churn, the relocation of staff within the building, will be dealt with within the agreed price, or are subject to pre-agreed tariffs, for example the cost of staff moves over and above an agreed number is set out in the contract. If organisational or other changes within MOD, however, require major changes to the scope of the project, the unitary payment will have to be adjusted. If MOD is unhappy with the contractor's pricing of the changes, it can require Modus to conduct a competition.
