Surveying existing firestops in a renovation: finding what is there and what is missing
The office renovation includes new services above occupied corridors. Some existing openings have old labels; others cannot yet be reached. The project manager needs an honest baseline and a route for unresolved protection and scope questions.
Define the survey area, responsible qualified people and assessed access before recording existing firestops. Capture located observations, available records and what could not be checked. Refer technical uncertainties and scope allocation through their appropriate reviews. A visible seal or an old label does not prove the complete concealed configuration, and a recorded pre-existing condition does not by itself decide who must pay to address it.
Record both findings and survey limits
- Agree the actual survey brief. Confirm the renovation boundaries, relevant protection information, required competence and purpose of the assessment. Arrange access and hazard controls through the site and owner processes, including occupied-area constraints. Ask the responsible professional to resolve unclear rated-assembly information. Do not open ceilings or disturb existing materials merely to populate a coordinator’s spreadsheet.
- Identify each observed location. Use consistent IDs and plan references for accessible openings and joint areas. Record the actual date, observation, photographs and available identification or historic documents. Distinguish a visible condition from a verified system match. If the record or concealed configuration cannot be established, mark that uncertainty instead of inventing a system from colour or appearance.
- Refer the required technical response. Report apparent damage, missing records and other relevant findings to the responsible team with their locations and evidence. Follow its assessed arrangements for affected protection and further investigation. The survey record supplies a question; qualified assessment determines the needed response. Keep inaccessible areas and follow-up access as separate open items.
- Review scope and changes separately. Compare the actual contract scope and instructions with the located findings through the authorized project team. Preserve the baseline and later work records. Identify disputed or additional scope for a decision rather than writing that every old defect automatically belongs to the owner. Technical risk response and commercial allocation may need different people and different timing.
Common mistakes
- Inferring an accepted system from colour or an old label.
- Marking inaccessible locations as satisfactory.
- Using pre-existing status as automatic liability allocation.
Checklist
State the baseline’s boundary
- Agreed area, purpose and qualified roles.
- Assessed access and actual limitations.
- Located observations and available evidence.
- Technical questions and required follow-up.
- Separate scope review and subsequent change records.
Check your understanding
An old labelled seal is visible above the ceiling. Can the baseline record call it verified compliant?
