Inspection Documentation, Reporting, and Recordkeeping
The report is the deliverable, and it must stand alone years later when the inspector is unavailable. Documentation begins in the field: field notes, sample logs, photographs with locations, sketches or floor plans marked with homogeneous areas and sample locations, and a record of inaccessible areas and why they were inaccessible.
A complete report typically includes: project and client identification; inspection objective and scope; dates and personnel (with accreditation information); a description of the building and systems; a table of homogeneous areas with material description, location, quantity estimate, friability, damage assessment, and asbestos content; laboratory reports and chain-of-custody records; a statement of limitations and inaccessible areas; and recommendations or next steps consistent with the objective (O&M, repair, removal, or further assessment). Keep the language factual and calibrated: 'sampled and found to contain' is defensible; 'probably safe' is not.
Recordkeeping has legal and practical dimensions. AHERA requires management plans and retention of records for schools. NESHAP requires notification records. OSHA requires exposure and medical records with retention periods. Good practice keeps the full project file, including raw notes and photographs, for the period your contract and jurisdiction require, and longer when litigation or real-estate transactions are foreseeable.
Traps: reports that list results without locations; missing limitations sections that later look like concealment; quantity estimates with false precision; and recommendations that exceed the inspector's role (an inspector identifies and characterizes; abatement design and oversight are separate functions).
Rule of thumb: write for a reader who was never on site and will read it in ten years. If a statement cannot be traced to a field note, a photo, or a lab report, it does not belong in the report.
