The level of complexity of a Change Procedure may also vary depending on whether the contract in question has different processes based around different values of any proposed change.
In the NPD /Hub Contracts, the Change Protocol is split into three distinct sections: Low Value Changes, Medium Value Changes and High Value Changes. This section provides an overview of each category to assist an Authority's understanding of each one should it decide to use the Change Procedure within its NPD/hub Contract to assist in the journey to NZ.
| Low Value Change (LVC) | Medium Value Change (MVC) | High Value Change (HVC) |
| Typically with an individual cost not exceeding £5k - index linked (though the amount can vary) | A Change requested by an Authority which is neither an LVC or an HVC | Typically a Change requested by an Authority which is likely to cost more than [£100k - index linked] |
| Includes those works and services listed in the Catalogue of Small Works and Services | This would typically be a Change that had a cost of between [£5k] and £100k (index linked) | Where a Change is likely to result in the Annual Service Payment rising by more than a stated percentage e.g. 2% |
| Derogated LVCs enable an Authority to undertake changes itself (or through its supply chain) rather than through Project Co |
| Where the Parties agree that a Change is to be treated as a High Value Change |
Some general principles to be followed in preparing and submitting estimated costs relating to a proposed Change include that costs must be kept to a minimum, capital expenditure is being measured in a cost-effective manner and in a manner that takes into account any foreseeable Changes in Law.
