Planning, sequencing and supervising work

Core idea

A useful job plan defines the result, constraints and verification before work starts. It identifies hazards, competence, access, isolations, materials, tools, interfaces with other trades and the order that avoids rework. Supervision then checks that the plan still matches changing site conditions.

What to recognise

• Confirm drawings, specifications and customer or site requirements before ordering and cutting.
• Assign tasks by actual competence and give clear limits for trainees or assistants.
• Plan safe access, isolations, permits and temporary services before the productive task.
• Arrange inspections and tests before work becomes concealed.
• Update the plan when conditions change instead of working around an unassessed surprise.

Apply it

For a bathroom alteration, sequence survey, isolation, protection, strip-out, first-fix routes, pressure or leak checks, building-fabric restoration, second fix, commissioning and handover. Coordinate electrical, ventilation and waterproofing interfaces. Record who accepts each concealed stage.

Keep the boundary clear

A programme date does not override safe isolation, competence or inspection. Supervising does not mean personally doing every task, but it does require clear instructions, monitoring and correction. Stop when asbestos, structural uncertainty, live services or another uncontrolled hazard changes the risk assessment.
