Advanced work packaging applies to brownfield and turnaround work with the same package logic as new construction. The project agrees the sequence, delivers engineering and materials in complete packages, and releases only constraint-free work. Because the work happens inside an operating plant, existing assets, existing documents, and safety-critical changes need their own rules.
The Existing Plant in the Model
The model separates the existing plant from new scope at the top of its hierarchy, and every object carries a scope type of dismantle, existing, new, turnaround, or relocate. Planners can then see which work touches existing equipment and cut packages around it. Model conditioning for AWP covers the attributes.
Existing Documents Stay Under Site Control
Drawings controlled by operations follow the site's drawing numbering standard. Existing drawings are checked out through the site drawing management team and are never renumbered by the contractor. When an existing document is revised, the originator code of the original stays unchanged, so its history remains traceable.
Safety-Critical Changes Go Through MOC First
Changes that touch P&IDs, plot plans, process safety data, interlocks, or hazardous area classification follow the full management of change workflow, with process safety approvals, before they are incorporated into an engineering work package.
Constraints in an Operating Unit
A constraint is any condition that prevents a task from being executed, and installation work packages are released only when they are constraint-free. Inside an operating unit, permits, isolations, and access windows join materials and documents on that list. A construction work package still starts only with 100% of its material on site, unless the construction manager accepts a backlog of constraint-free packages. Material readiness covers the material rules.
Turnarounds
A turnaround compresses execution into a fixed shutdown window, so the make-ready work has to be finished before the unit comes down. Each work order is linked to its equipment, the sequence is checked before the event, and progress is tracked per equipment through milestones suited to the work. Workface planning covers the crew-level planning.
How openAWP Supports It
openAWP holds turnaround work orders as records linked to equipment in the plant model, created in openAWP, imported from Excel, or sent in from the maintenance system through its API. Isolations and permits are tables that reference the work orders, and constraints hold packages out of release. The shutdown window is planned on the lookahead and played through in 4D, and progress rolls up with milestones such as isolated, opened and inspected, work executed, closed and reinstated, tested, and returned to service.
