Integrated Primavera P6 schedules
Develop Level 1–4 schedules from project milestones through detailed work packages. Establish work breakdown structures, calendars, coding and logic that can be maintained by the delivery team.
02 / 4D construction planning and scheduling
Test the sequence before it reaches site
Schedules are developed against an agreed work breakdown structure and linked to the BIM model, so the proposed sequence can be simulated, coordinated across contractors and challenged while changing it is still practical. Access, work areas and overlapping activities are reviewed with the delivery teams rather than assumed.
Purpose & approach
A schedule should explain how the project will be built.
A credible schedule connects scope, access, resources and handovers. We work with project teams to build a schedule that reflects these relationships, then use structured updates to keep the plan relevant as conditions change.

Explore the sequence.
Compare the work fronts.
Explore the order of work in an illustrative model. A project review also needs the agreed logic, access constraints and handover conditions.

What we do.
The service is tailored to the assignment. We agree the scope, required inputs and acceptance criteria before delivery.
4D construction sequencing
Link agreed BIM objects and model areas to schedule activities. Review the sequence visually to identify access constraints, space conflicts and the order of work across disciplines.
Interfaces and readiness
Connect design releases, procurement, installation, testing and handover. Record prerequisites and make ownership of each interface clear before work enters the look-ahead.
Progress and look-ahead planning
Apply agreed progress rules, assess the critical and near-critical paths and prepare short-term plans. Separate reported progress from the evidence supporting it.
Resources and recovery options
Review resource demand, work fronts and opportunities for resequencing. Compare recovery options against the baseline and document the assumptions behind each option.
Planning workshops and reporting
Bring contractors and stakeholders into structured planning sessions. Issue clear milestone, variance and exception reports that explain what has changed and where action is needed.

PALLAS reactor
IFC models linked to the schedule to review construction sequences, work areas and interfaces.
Petten, Netherlands
Build the sequence from the model.
At PALLAS, construction models are linked to the schedule in a 4D environment. Activity coding, model objects and work areas are aligned so that proposed sequences and changes can be reviewed together.
Read the project accountYour questions
Define the right assignment.
Do we need a BIM model to begin?
No. Schedule development and readiness planning can begin with the available scope and schedule information. 4D work requires a suitable model and an agreed method of linking objects to activities.
Can you work with an existing P6 schedule?
Yes. We can review and develop an existing schedule, establish a consistent update process and document changes to structure, logic and progress measurement.
