Best Practices

Contractors can improve their Cote Qualité GCR through the application of Best Practices. These practices help diligent contractors construct buildings of even higher quality than required by standards in force.

There are 18 Best Practices that can be applied to any project registered and initiated starting February 1, 2018.

The application of Best Practices can help contractors boost their technical rating, improving their Cote Qualité GCR. Two additional points will be added to a project’s technical rating for every Best Practice observed or demonstrated, up to a maximum of 10 points.

For example, if a contractor builds a single-family residence that integrates four Best Practices, the technical rating will receive eight additional points. Instead of 88%, the project’s final technical rating will be 96%, which will significantly impact the Cote Qualité GCR.

The Best Practices below can boost a project’s technical rating, provided that the project has undergone at least one random inspection and that proof of the Best Practice has been confirmed by a GCR inspector, either during the site inspection or through subsequent proof provided to GCR.

^{(1) For Best Practices points to be granted, the practice must be completed by the inspection date and the builder must provide photographic evidence.}

^{(2) For Best Practices points to be granted after the fact, the builder must provide photographic evidence that the practice has been applied. In each picture, we must be able to see the building’s address, the lot number or the project’s GCR file number. The builder must provide enough wider shots and close-ups for an overall assessment of the work.}

^{(3) With the exception of Best Practice 13, all evidence provided to GCR after an inspection must be obtained before the completion of work.}

Useful info

To ensure appropriate follow-up in a timely manner, GCR asks contractors to provide documentation or proof demonstrating the application of Best Practices when the site is inspected. This can also be provided later, if work on the Best Practice has not been initiated or finished at the time of the inspection. In this case, the contractor is responsible for sending proof of the practice’s application to GCR.

Photographic proof of work must contain the building’s address, the lot number or the project’s GCR file number. The contractor must also provide enough wider shots and close-ups for an overall assessment of the work.
