Planning, sequencing and 4D
Does the programme match the model?
Linking the programme to the model shows the sequence before it happens: logic errors, workspace conflicts, crane coverage and phasing. It only works if the model is split the way the work is.
Understand
What it is, in plain language
- Pedia · Workflows4D planning (linking the programme to the model)Connecting each activity in the construction programme to the model elements it builds, so the sequence can be watched, checked and explained before it happens on site.
- Pedia · WorkflowsSite logistics modelsModelling the temporary site, from cranes, hoists and scaffold to deliveries, storage and welfare, and how it changes over time, so the site works as well as the building.
- Pedia · GlossaryLocation breakdownHow a project is divided into buildings, levels and zones, used consistently by models, programmes and cost plans.
- Pedia · Workflows4D and 5D BIM (time and cost)Linking model elements to the construction programme (4D) and to quantities and cost (5D), and what each is useful for.
Learn
Short lessons with a quick check
- Lesson · 6 min · quizLinking the programme to the model (4D)4D only works when the programme and the model share a breakdown. Agree it, code both, link by rules, and the sequence keeps working when the model changes.
- Lesson · 3 min · quizPlanning the site around the modelMost site problems involve temporary things: cranes, hoists, scaffold, deliveries and storage. A logistics model, phase by phase, checks them before the site does.
Do
Tools that export Excel, PDF and Word
- Tool · Excel · PDF · Word4D SimulatorUse it to check a programme against the model before it goes to site, to show the sequence to the team, or to see where the job stands against the plan.
- Tool · Excel · PDF · Word3D IFC ViewerUse it to look at a model without installing software, or to show where requirements fail.
- Tool · Excel · PDF · WordIFC to Excel SchedulesUse it when you need quantities, a door or equipment schedule, or a property review from an IFC model in Excel.
How it works
The process, at a glance
- 1Agree the breakdownLevels, zones, pours and work packages
- 2Code the programmeEach activity gets a code: L03-Z1-FRAME
- 3Code the modelElements carry level, zone and package properties
- 4Link by rulesActivity ↔ elements with matching codes
- 5Play and checkLogic, workspaces, logistics, every update
Common mistakes
What goes wrong most often on real projects.
- Linking elements by hand so the 4D model breaks at the next revision.
- A model that can't be split like the work (one slab per level when it's poured in zones).
- Showing only permanent works and ignoring temporary works and logistics.
- Building a 4D animation for the tender and never updating it.
