Completion

The certificates that actually move money

Practical completion is not a tidy site. It is a certificate, and on the date it carries, five separate things change at once. A program that prints the certificate and leaves the figures alone has done the easy half.

Issuing the certificate changes the arithmetic

Enter the date on the certificate and the retention halves from that valuation, the rectification period starts, and liability for liquidated damages ends. You do not enter the date twice.

The same applies to making good. That certificate releases the balance of the retention, and QScope will not let it be issued while items remain outstanding on the schedule of defects, because that releases the last of the security for work nobody has done.

  • Practical completion, partial possession, non-completion, making good and the final certificate
  • Each certificate prints as a formal document with the clause reference and its consequences
  • The certificate governs over the settings field, with a warning if the two disagree
  • Making good blocked while defects remain outstanding

Sections and partial possession, handled separately

Where the contract divides the works into sections, each has its own completion date, its own damages rate and its own retention release. A section handed over in March should not be waiting on a contract that finishes in November, and in most systems it is.

Partial possession works the same way. Give the part a value and QScope releases retention against it as if it had reached practical completion, and reduces the damages rate in the same proportion, from the date of possession rather than retrospectively.

  • Sections with their own value, dates and damages rate
  • Retention released against the section, at that section’s practical completion
  • Partial possession reduces damages proportionately from the date of possession
  • A warning when section values do not reconcile to the contract sum

Half the retention attributable to each section is released at that section’s own practical completion, not at the end of the contract.

Damages that survive being challenged

The calculation takes a minute. The procedure is where the money goes: under a JCT form the employer cannot deduct until the contract administrator has certified non-completion and the employer has given notice.

QScope calculates damages from the completion date after any extension, applies any cap, and refuses to let the figure stand unqualified while no certificate of non-completion is on the register. A deduction made in the wrong order is not a smaller deduction. It is repayable in full.

  • Damages run from the revised completion date, not the original
  • Cap applied where the contract states one
  • Red warning where no certificate of non-completion has been issued
  • Rate reduced proportionately after partial possession

The certificate hands the retention to the retention module

The moment practical completion is certified the held retention halves, and QScope carries the new figure straight onto the retention notice the client receives. The number on the certificate and the number on the notice are the same number.

Half the retention is released now. The balance waits on the certificate of making good, and the project list warns you as the release date approaches so unclaimed retention does not quietly stay with the employer.

  • Release notice printed for the client on your letterhead
  • Balance held to the end of the rectification period

Making good releases the last of it

The certificate of making good releases the balance of the retention, and it depends on the schedule of defects being clear. QScope will not let it be issued while items remain outstanding, because that hands back the last of the security for work nobody has done.

The schedule and the certificate are two views of the same fact, so the release cannot run ahead of the repairs.

  • Rectification end date calculated from the completion certificate
  • Making good blocked while defects remain outstanding
  • Notified and made good held as separate dates on every item
  • Balance of the retention released only when the schedule is clear

Questions

What surveyors ask before they start

Do I still need to enter the practical completion date in settings?

No. If a certificate is on the register, that date governs, because the certificate is the document the contractor received. If both are filled in and they disagree, QScope tells you and applies the certificate.

What if the works are sectional but the contract sum is not split?

Give each section a value that reconciles to the contract sum. QScope warns you when the values do not add up, because retention is released against them and an unreconciled split releases the wrong amount.

Can I issue a certificate of practical completion subject to outstanding items?

The contract does not really allow it, because the consequences cannot be made conditional. Record outstanding work as a separate schedule and issue an unqualified certificate.

Does the certificate stop damages automatically?

Yes. Damages run to the date of practical completion and no further, and the calculation uses the certified date.
