In addition, the NEC4 form expressly provides that if the completion date changes to a later date after the liquidated damages for delay have been paid, the employer is to repay the overpayment of damages with interest.(#footnote-95) [...] #### Other standard contract forms\n\nThe NEC4 form adopts a different approach. Instead of including a separate force majeure regime, it provides for a compensation event that has a similar effect. Clause 60.1(19) allows the contractor relief in the case of a compensation event if it can demonstrate that it is something neither party could prevent, an experienced contractor would have judged the event to have had such a small chance of occurring that it would have been unreasonable to have allowed for it, and it is not covered under any of the other compensation events under the contract. [...] #### Other standard contract forms\n\nAll other standard forms, other than the LOGIC contract form, generally allow the contractor to claim both time and cost. The LOGIC contract form only allows for an adjustment to the contract price, but not to the time for completion.(#footnote-91)\n\nNEC4 provides for a change in law provision, but it has only been included as a secondary option clause.(#footnote-92) If the relevant option provision is incorporated, it provides that any change in law may be a compensation event, shifting much of the risk to the employer. It also provides that, where the effect of a change in law is for the overall costs to decrease, the contract price typically may be reduced to reflect that decrease.(#footnote-93)\n\n### Delay\n\n#### 1999 FIDIC contracts",
