Who is responsible for writing an evaluation report?

The manufacturer is responsible for writing the evaluation report. This report plays a crucial role in documenting how a product or material meets specific standards or codes. Manufacturers have the required expertise and knowledge about their products, enabling them to provide detailed information regarding performance, safety, and compliance with relevant regulations.

An evaluation report typically includes test results, design information, and any limitations of the product, which are essential for ensuring that the material can be used safely in construction. The responsibility of the manufacturer is key, as they possess the authority and data necessary to validate the claims made about their products.

The other options do not align with the standard practices surrounding evaluation reports. For example, while the building official may review these reports, they do not write them. Similarly, the owner and special inspector might have input or require reports for compliance and inspection purposes, but they are not responsible for creating the evaluation report itself. This clarifies why the manufacturer is indeed the correct answer.
