Handling Errors and Rework in Outsourced Drawings

Errors happen in every team. What matters is how quickly they're found, fixed and prevented next time.

Errors happen in every production process, whether in-house or outsourced. What matters is how they're found, fixed and prevented. A calm, structured approach keeps projects on track and improves the partnership.

Find errors early

The earlier errors are found, the easier they are to fix. Short review cycles and layered checks help catch errors before they spread across drawings.

Describe errors clearly

When reporting an error:

  • Identify the sheet, view or element
  • Describe what's wrong
  • Explain what's correct
  • Provide references, such as markups or standards

Clear descriptions help the team fix errors quickly and correctly.

Prioritise

Not all errors are equal. Prioritise those affecting:

  • Safety and compliance
  • Coordination with other disciplines
  • Imminent issues or submissions

Minor presentation issues can be grouped and fixed together.

Find the cause

  • Was the brief unclear?
  • Was information missing or outdated?
  • Was a standard not shared or not understood?
  • Was the deadline too tight for checking?
  • Was it a simple mistake?

Understanding the cause helps prevent repeats.

Corrections versus changes

Distinguish errors against the brief from changes in requirements. Agreements often treat them differently, so being clear avoids disputes.

Agree how rework is handled

Agreements should explain how corrections are handled, including timescales. Clear arrangements make discussions straightforward.

Prevent repeats

  • Update checklists with recurring errors
  • Clarify standards
  • Improve briefs
  • Provide examples
  • Offer short training sessions

Keep a log

A log of errors, causes and actions shows patterns over time. It's useful in performance reviews.

Stay constructive

Errors are learning opportunities. A blame-focused response discourages teams from raising concerns. A constructive response encourages openness and improvement.

Check fixes

When corrected drawings return, check that errors are fixed and no new issues have been introduced. Compare tools help.

Escalate when needed

If errors persist despite feedback, escalate through agreed channels. Persistent issues might need changes to the team, process or scope.

Plan for review in the programme

Rework is much easier to absorb when the programme includes review time. Tight programmes with no review time turn small errors into deadline problems.

Share good examples

Alongside errors, share examples of work done well. Showing what good looks like helps the team understand expectations.

Review the process periodically

Every few months, look at the error log with the partner and agree process improvements.

Handling errors well builds trust, improves quality and makes the partnership stronger over time.
