1. Changes are a natural part of any construction project
2. Changes require the subcontractor to do something “in addition to or in place of the originally agreed, that the nature, quality, nature or performance of the benefits shall be changed, or that the agreed benefits shall be discontinued”
3. The subcontractor is not obliged to carry out modification works beyond 15% net of the contract amount, which means that reduced work should also be taken into account in the calculation
4. Change orders are issued by the total/general contractor's representative or one with a special (written) power of attorney
5. In some cases, a change may also be made by order of the total/general contractor
6. If the subcontractor finds that he has received an order or instruction concerning something he considers to represent a change, but without an order for change having been issued, the subcontractor must notify “without undue delay”.
7. If the subcontractor does not notify within the deadline, the right to invoke the relationship as an amendment lapses
8. Total/general contractor must take a position on the notice and respond to subcontractor “without undue delay”
9. Otherwise, the notified relationship shall be considered to be a change
10. Anyone who claims that the other has notified or responded too late must himself notify the other that he thinks so — “without undue delay”
