Project templates for fleet construction let a team configure one nuclear project, then reuse that setup on every later unit and site. Nuclear construction fits this approach well, since the same plant scope often repeats across units and sites. When EPCs build the first unit's project with reuse in mind, the next team starts from a project configured like the last one instead of a blank page.
Repeating scope gives a construction team something a one-off project doesn't: a second pass at the same work. Crews who install a plant system on the first unit learn where the sequence stalls, which constraints cause holds and how long each package takes. On the next unit, planners who keep what those crews learned can set tighter durations and clear constraints earlier.
What crews learn needs a way to reach the next unit. Construction at another site may start years later, with new planners, a new laydown plan and sometimes a different EPC. On capital projects, lessons learned often end up in a closeout report that later teams rarely open, so crews rediscover the same problems in the field. Keeping each lesson in the project template puts it where the next team will look.
Advanced Work Packaging (AWP) gives planners a structure for keeping those lessons: a project they can template and reuse from one unit to the next. On the first unit, they set up the Path of Construction (PoC), the Construction Work Package (CWP) breakdown and the Installation Work Package (IWP) scopes once. They then template the project itself, so the next unit starts already configured like the first.
Four parts of the first unit's project setup carry over with little change:
Each new site brings conditions the first unit's plan can't settle in advance. Planners record each site's differences in the project, so the next team can see which parts of the setup are proven and which are new. The differences include:
Crew availability is one difference planners can model ahead of time. Skilled labor is scarce on nuclear projects, and every crew mobilized adds cost, so planners need to see how staffing levels, productivity and working hours will affect budget and schedule before a new unit starts.
A repeated plant scope keeps changing after the first unit. Engineering teams issue revisions for design updates, field changes and lessons from earlier units. Planners on every unit have to apply each revision. A team that misses a design update builds from an outdated package, and its crews redo work that other units got right.
To keep every unit in sync, planners need two things: up-to-date data behind each package and AWP software connected to the engineering, schedule and materials systems each site already uses. With both in place, a design update reaches every unit at the same time.
A project template is a project's finished setup, including its PoC, work breakdown, constraint checklists and rules of credit, saved so the next unit or site starts configured the same way. Planners adjust it for each site, so later units don't start from scratch.
Planners spend more time on the first unit configuring the project and recording constraints and actuals. Every later unit then starts from that setup instead of rebuilding the plan. The efficiencies gained from Advanced Work Packaging in O3 make this arbitrary.
Yes. Each EPC starts its own project from the template and records its site's changes there, so an EPC joining the program starts with the configuration from earlier units.
On energy projects, including nuclear, Owners and EPCs want every new unit to build on the units before it. Owners planning multi-unit programs often choose the AWP software on the first site and carry it to every site after, so the EPC's first-unit plan becomes the starting point for the rest. Here's how each team benefits from O3:
In O3, planners build one nuclear site, then template that project, including its PoC, work breakdown, constraint checklists and rules of credit, so each new unit starts configured like the last one. Worley shows where reusing one AWP setup leads. After making AWP its global standard, Worley’s teams set up O3 on new projects with no implementation support.
For staffing at each new site, planners can run What If scenarios in O3, testing extra crews, crew size, productivity and working hours against the AI-enabled IWP sequence. Each scenario shows what is at stake in budget, hours and schedule, so the team commits crews with a staffing plan it can defend.
O3 provides enterprise-grade data management that runs itself. Project data arrives from the places it already lives, validated and current; gaps become assigned tasks before they reach the field, and teams build from the latest revision every day. O3 integrates with any system seamlessly through out-of-the-box (OOTB) integrations or enterprise REST APIs, so planners on every unit work from the same 3D model, schedule and materials data.
Nuclear programs run for a decade or more, so Owners and EPCs need a software partner for the long term. O3 has supported 600+ projects and 30,000+ users. Our guide to AWP for nuclear construction covers how AWP applies to both refurbishment and new build work.
