Is the project ready to connect the model, programme and cost plan?

Work through the controls that make 4D sequencing and 5D cost planning useful. You will get a practical list of gaps and the smallest sensible pilot to run.

What are you preparing?

Choose a route, rate each control and use the result to plan the smallest sensible pilot.

Project or package

Intended use

Start with the project decision, not the software.

0/3

DecisionCriticalIs the intended use stated—for example sequence review, logistics, progress monitoring, quantity review, cost planning or change evaluation?Audience + outputAre the users, required views or reports and issue dates agreed?Scope boundaryAre included disciplines, zones, stages and exclusions clear?

Programme coding

A model cannot link reliably to activities that have no stable identity.

0/3

Programme control basisCriticalIs there a controlled baseline, current status date, calendars, milestones and logic?Stable activity codingCriticalDo activities have stable IDs and useful WBS, location, trade or work-package codes?Useful activity breakdownDoes the programme describe work at a level that can be represented in the model?

Model breakdown

The model needs to be grouped in the same language as delivery.

0/3

Controlled model setAre the relevant discipline models coordinated, versioned and located consistently?Construction breakdownCan elements be filtered by level, zone, system, trade, package or construction phase?Stable mappingCriticalIs there an agreed rule connecting model objects to activities, quantities or cost items?

Quantity basis

A quantity becomes useful when everyone agrees how it is measured.

0/3

Measurement rulesCriticalAre units, inclusions, exclusions, deductions, waste and gross or net rules stated?Measurable informationDo relevant elements contain suitable geometry, classification and parameters?Reconciliation routeAre model-derived, BOQ-derived and manually assessed items distinguished?

Cost structure

Model quantities and commercial cost lines need a deliberate mapping.

0/3

Cost codingCriticalDoes the cost plan have stable IDs and a structure that can map to quantities and work packages?Cost basisAre rate sources, currency, base date, taxes, escalation, allowances and contingency stated?Cost statusAre budget, committed, actual, forecast and approved-change values kept distinct?

Change control

Controlled reference versions let the team explain what changed.

0/3

BaselinesCriticalCan the exact model, programme, quantity and cost versions used for each issue be identified?Change recordDoes every accepted change have an ID, owner, date, status and affected scope?Reforecast routeIs it clear when approved changes update the baseline, forecast and published output?

Responsibility

Named people need to prepare, check and approve every source.

0/3

Source ownersCriticalAre the programme, model, quantities and costs owned by named roles?Review + approvalIs it clear who prepares, checks, accepts and authorises changes?Boundaries + accessAre responsibility, commercial authority, file access and sharing rules understood?

Validation

A representative test finds mismatched codes before they affect the whole project.

0/3

End-to-end pilotHas one representative zone, package or period been linked and reviewed?Exception checksAre unlinked objects, unmatched activities, duplicates and unmapped items reported?AcceptanceAre tolerances, reconciliation checks, visual reviews and sign-off requirements defined?

Update cadence

The model, programme and cost information need a repeatable update rhythm.

0/3

Status rhythmAre the status date, update frequency and information cut-off aligned?Exchange processAre naming, formats, workspace, meeting cycle and comment deadlines agreed?History + recoveryAre issued snapshots, mapping tables, changes and approvals archived?

What this means
Agree what the workflow should support, appoint source owners and gather one representative set of project information.

Critical blockers
- Decision: Write one sentence stating the decision the output must support.
- Programme control basis: Confirm the programme version, status date and approval status.
- Stable activity coding: Agree the coding fields that will survive programme updates.
- Stable mapping: Define linking fields, many-to-many rules and treatment of unmodelled work.
- Measurement rules: Agree the measurement basis before extracting or comparing quantities.
- Cost coding: Create the model or quantity-to-cost-code mapping table.
- Baselines: Freeze and name the starting references.
- Source owners: Assign one accountable owner to each source.

The result checks the planned setup, not the project files. Programme logic, model quality, measured quantities, rates and professional cost advice require review by the responsible project team.

Start with control, not software

A moving model is not yet a dependable plan.

For 4D, activity codes and model zones need to meet. For 5D, measured quantities and cost codes need the same discipline. The checklist keeps those controls visible.

Have the current programme, a representative model, the cost breakdown and the responsibility route nearby. Missing information becomes part of the action list.
