Sequence fireproofing with deck, attachments and services using the actual system
The electrical foreman wants to install cable racks on the next office floor before fireproofing begins. Clips are partly complete and the roof contractor still needs access above. You need a sequence that records the actual dependencies instead of giving every trade the same start date.
Build the sequence from the selected fireproofing instructions and the actual area's readiness, then mark the trade handovers in the look-ahead. A Canadian spray-product example requires relevant attachments before application and suspended services afterwards, with deck-related completion conditions. Confirm your system's requirements rather than making that example a universal sequence.
Create a sequence with evidence at each handover
- Divide the work into identifiable areas. Use levels, grids and member references that the trades and agency can recognize. Mark each area's product and protection arrangement. Keep roof-deck areas separate where their prerequisites differ from a completed floor, instead of colouring the entire storey ready because some steel is accessible.
- Confirm deck and overhead prerequisites. Obtain the actual product and project requirements for deck work, roofing, attachments and access. Ask the responsible trades to state what remains and how completion will be recorded. Route an unclear requirement through the consultant or manufacturer before building a programme around your interpretation.
- Coordinate the attachments individually. Have electrical, mechanical and sprinkler leads identify clips, supports and other interfaces on the same area plan. Record the approved detail and intended order for each. An attachment marked complete needs a location and scope; an unresolved connection cannot be covered by the general note 'MEP ready'.
- Reserve the spray work area. Agree access, adjacent protection and the conditions for other activity with the applicator and superintendent. Identify service installations that would obstruct the required application. Give affected trades the area boundary and handover arrangement, then verify the actual condition before the crew mobilizes.
- Plan inspection and trade return separately. Book the agency against the selected checks and material readiness requirements. Record who confirms application completion, unresolved defects and the conditions for later trade access. A provisional visit does not release an area, and trade return does not mean the protection may be altered without a repair decision.
- Update the look-ahead after changes. Record missing attachments, access conflicts and technical queries against the affected areas. Re-sequence a resolved area where practical. Brief later trades on damage reporting and keep any new attachment proposal linked to the protection details.
Common mistakes
- Recording a whole floor ready while roof prerequisites remain open.
- Using 'MEP complete' without identifying attachment scope.
- Treating a booked inspection as authorization to install obstructing services.
Action list
Put these entries in the area sequence
- Area and protection arrangement.
- Deck and roof prerequisites.
- Attachment scope and completion record.
- Spray access and protection boundary.
- Agency readiness and trade-return decision.
- Changed interface and damage-report route.
Check your understanding
The clips are installed, but roof traffic continues over the area. Is the area ready for spray?
