A Forensic Investigation, as it applies to structures, involves a systematic gathering and analysis of data to determine the cause of a structural failure or distress, and assess the risks the problem poses to the public. A Structural Forensic Investigation is similar in scope to a Building Condition Assessment. In the province of Ontario, the report generated has to conform to the documentation requirements of Rule 53.03 of the Rules of Civil Procedure.

As described in item 6 above, a Site Inspection, also known as a General Review of Construction, refers to a review of construction in progress by the design engineer or architect. It is intended to ensure that the as-built structure conforms to the permit drawings and specifications. At the end of each site visit, the engineer or architect produces a report that summarizes the findings. The Ontario Building Code (OBC) requires that a copy of the report is sent to the chief building official. The document forms part of the property record. A copy of the report is also sent to the property owner, the building contractor and other parties involved.
