The detailing workflow in three phases

Every project moves through three phases: pre-detailing, detailing for approval, and detailing for fabrication and construction. Five roles take part:

• Project Manager
• Lead Detailer / Project Coordinator
• Modeller
• Checker
• Editor

This lesson gives the big picture. The following modules go through each part in detail.

Phase 1: Pre-detailing

Project Manager

1. Project admin: prepare and hand over the project input.

Lead Detailer / Project Coordinator

1. Project review (create TQs for any conflict, for clarification).
2. Fill up the Detailing Readiness Checklist.
3. Initiate the kick-off meeting.
4. Create the Detailing Checklist.
5. Assign the modelling task.

Modeller

1. Model set up.
2. Model grids.

Checker

1. Check model set up and grids.

Editor

1. Edit grid line drawings and print for reference.

Handoffs: the Project Manager hands the project input to the Lead Detailer, who reviews it, runs the kick-off and assigns modelling. The Modeller sets up the model and grids and passes them to the Checker, and the Editor then edits and prints the grid line drawings for reference.

Phase 2: Detailing for approval

Lead Detailer / Project Coordinator

1. Project administration and control throughout the phase.
2. Final review at the end.

Modeller

1. Stick model.
2. Connecting: anchor/HD bolts.
3. Connecting: reference objects.
4. Connecting: main steel.
5. Connecting: secondary steel.
6. Modelling/connecting: miscellaneous steel.
7. Clash checking.
8. Phase check/update.
9. Model properties check/update.
10. Numbering.
11. Model fixing as needed.

Checker

1. Checking: stick model.
2. Model checking: anchor/HD bolts.
3. Drawing checking: anchor/HD bolts plan and details.
4. Connection checking: main steel.
5. Connection checking: secondary steel.
6. Connection checking: miscellaneous steel.
7. Constructability checking.
8. Visual checking for duplicate steel.
9. Checking: GA drawings.
10. Checking: assembly drawings.
11. Checking: part drawings.

Editor

1. Create/edit: anchor/HD bolts.
2. Create/edit: GA drawings set up.
3. Update: GA drawings.
4. Create/edit: assembly drawings.
5. Create/edit: part drawings.
6. Backdrafting: GA and shop drawings.

Project Manager

1. Issue advance bill of materials.
2. Issue for approval: anchor/HD bolts plan and details.
3. Issue for approval: steel package (after the Lead Detailer's final review).

Handoffs: the Modeller's work at each stage goes to the Checker; checked work goes to the Editor for drawings, which come back to the Checker; any model fixing returns to the Modeller. The Lead Detailer's final review comes before the Project Manager issues the steel package for approval.

Phase 3: Detailing for fabrication and construction

Project Manager

1. Project admin: prepare and hand over the approval return drawings.
2. Issue for fabrication and construction (at the end).

Lead Detailer / Project Coordinator

1. Review approval return drawings.
2. Create TQs for clarification.
3. Prepare documents for model fixing.
4. Prepare documents for backdrafting.
5. Final review (at the end).

Modeller

1. Model fixing/numbering.

Checker

1. Check model fixing applied.
2. Constructability checking.
3. Checking: GA drawing.
4. Checking: shop drawings.

Editor

1. Drawing update: GA drawing.
2. Drawing update: shop drawings.
3. Backdrafting: GA and shop drawings.

Handoffs: the Project Manager hands the approval return drawings to the Lead Detailer, who prepares the documents for model fixing (to the Modeller) and backdrafting (to the Editor). The Checker checks the fixed model and updated drawings, and after the Lead Detailer's final review the Project Manager issues for fabrication and construction.
