10. Documentation: The Backbone of CQC

A meticulous record of inspections, tests, deviations, and corrective actions forms the backbone of quality control. Proper documentation ensures transparency and provides a historical record that can be invaluable for future reference or audits.

11. Concluding with Final Inspections

As the project nears completion, addressing every item on the punch list ensures nothing is overlooked. Systems tests, covering aspects like electrical setups or plumbing, certify that everything is operational and up to standard. Preparing comprehensive handover documents aids in a smooth transition to the client.

12. Review and Feedback

Post-construction, capturing feedback from the client and conducting a project review can offer invaluable insights. These reflections not only gauge the success of the current project but provide lessons for future endeavors.

In essence, the CQC checklist is more than a list of tasks—it’s a doctrine that ensures every construction project stands as a testament to quality, safety, and excellence.

Challenges in Construction Quality Control

Quality control in construction is crucial for delivering projects that are safe, durable, and meet the intended specifications. However, maintaining a high level of quality control in the construction sector can be quite challenging. Here are some of the most common challenges faced:
