Who patches fireproofing: define the repair and responsibility process
A sprinkler crew and an electrical crew have both worked along a warehouse corridor. Fireproofing is missing near several attachments, and each foreman says it was already damaged. You need the repair arranged and the commercial decision supported, without pretending a photograph proves who caused it.
Agree the damage-reporting, repair, review and payment process before later trades enter the area. Responsibility comes from the actual contracts and evidence, while the repair method comes from the approved protection requirements. A manufacturer's public guide specification illustrates assigning later-trade damage costs, but its wording does not automatically become your subcontract agreement.
Define responsibilities before the first dispute
- Read the actual scope allocation. Compare the fireproofing and affected trade subcontracts with relevant project requirements. Distinguish initial application defects, inspection sample repairs and damage caused by later activity. Record any missing or contradictory allocation for the project manager rather than declaring that all return visits belong to one trade.
- Name the reporting route. Ask trades to report observed damage with a location, time, description and permitted photographs. Identify who receives the notice and who coordinates the response. Require the record to distinguish observed facts from assumptions about cause; a bare flange beside a pipe is not proof of who removed the material.
- Name the authorized repair arrangement. Identify the installer and technical review route for the actual system. The opened Canadian patching instructions show that a repair product can have specific permitted materials and area limits. Do not authorize general filler, leftover spray or a convenient trade's repair merely because it looks flush.
- Define review and access conditions. Confirm who checks the proposed method and completed work, including any required tests or inspection. Keep the affected area available under the project's arrangements until review is complete. Record the difference between a repair completed by the installer and a repair accepted by the responsible reviewer.
- Agree how costs are recorded. Use the contract's pricing, notice and dispute process with location-specific labour, material and visit records. Do not deduct a charge or admit liability from this lesson. Where cause remains disputed, preserve the evidence and commercial question while arranging the necessary technical response.
- Brief and maintain the agreement. Put the confirmed roles and unresolved items in the startup record and trade briefings. Update it when arrangements change. Review recurring damage locations with the trades so the agreement supports prevention as well as the next invoice.
Common mistakes
- Using 'patching by others' without identifying a process.
- Waiting for a fault argument to finish before arranging the technical response.
- Treating a repair photograph as acceptance or proof of liability.

Check your understanding
A photograph shows missing material beside a sprinkler hanger. Does it settle the charge to the sprinkler trade?
