The spine the whole pack is built on
The work broken into a defensible step-by-step sequence with predecessors, durations, hold points and the critical path made explicit. The method statement is built around this. Hazards are mapped against it. Compliance is structured against it. Twenty-one tasks across six phases, four hold points and an eighteen-day critical path.

Six phases, at a glance
The programme runs three weeks, Monday 18 May to Friday 5 June 2026, from pre-erection verification through to handover of the frame to the following trade.
| Phase | Coverage | Duration |
|---|---|---|
| P1 Pre-erection | Setup, survey, bolt check, lift plan (T01 to T04) | 2 d |
| P2 Frame Level 1 | Baseplate to L1 secondary (T05 to T08) | 4 d |
| P3 Frame Level 2 | L2 columns to bracings (T09 to T12) | 3.5 d |
| P4 Frame Level 3 | L3 columns and beams (T13 to T15) | 3 d |
| P5 Roof level | Ridge, secondary and purlins (T16 to T17) | 1.5 d |
| P6 Finishing | Torque, fire protection, sign-off (T18 to T21) | 4.25 d |
The six displayed phase durations total 18.25 days. The example does not state an overlap, calendar or rounding basis reconciling this sum with the 18-day critical-path figure.
The detailed sequence
A sample of the task table showing predecessors, durations and type. Six tasks sit on the critical path; four are hold points that stop work until inspected.
| ID | Task | Pred | Dur | Type |
|---|---|---|---|---|
| T02 | Survey and set-out verification | T01 | 0.5 d | Hold point |
| T03 | Holding-down bolts level check | T02 | 0.5 d | Hold point |
| T06 | Column erection Level 1 | T05 | 1.5 d | Critical path |
| T07 | Primary beam connection L1 | T06 | 1.0 d | Critical path |
| T13 | Column erection Level 3 | T10 | 1.0 d | Critical path |
| T18 | Final torque-up and weld inspection | T17 | 1.5 d | Hold point |
| T20 | Final dimensional survey | T19 | 0.5 d | Hold point |
How the sequence governs the pack
This task sequence is the spine of the RAMS pack. The hazard-risk-control matrix maps hazards to each task ID. The PPE and plant schedule maps requirements per task. The permits and isolations checklist cross-references permit needs against the hold points. If the sequence changes, the downstream outputs change with it, so the workflow stays governed end to end.
The critical path runs through the level-by-level column and primary-beam erection. The four hold points, survey set-out, holding-down bolts, final torque with weld inspection, and the final dimensional survey, each stop work until the inspection is signed.
