[edit] Certificate of non completion
[edit] Introduction
The date for completion of construction works (or dates for completion of sections of the works) is generally set out in the contract particulars.
However, it is not uncommon for delays to cause the completion date to be missed, that is, the works are not complete, and so a certificate of practical completion cannot be issued by the date for completion.
Where the client is responsible for the delay, an extension of time may be granted, the completion date adjusted, and the contractor may be entitled to claim loss and expense.
Where the contractor is responsible for the delay, the client may be entitled to claim liquidated and ascertained damages (at a rate set out in the contract particulars).
Some contracts (such as the JCT Standard Form of Building Contract) require that the contract administrator issues the contractor with a certificate of non-completion (sometimes referred to as a ‘non-completion certificate’ or ‘non-completion notice') as a pre-requisite to claiming liquidated and ascertained damages.
The certificate of non-completion gives formal written notice to the contractor that they have failed to complete the works described in the contract by the completion date that was last agreed (the original completion date may have been adjusted during the course of the works).
The contract administrator must give due consideration to any applications for extension of time before issuing a certificate of non-completion, and if there are subsequent extensions of time that result in the completion date being adjusted, and the contractor then fails to meet this adjusted date, a new certificate of non-completion must be issued.
Where the contract provides for sectional completion of the works, separate certificates of non-completion must be issued for each section that is not completed by the required date.
