Evidence you can inspect

Understand what stands
behind an answer.

See which figures come from you, which are starting assumptions, and what to check before using a result in your project.

How these planning tools work

The 5 published tools use guided questions, proposed capacity scenarios, trial allowances, fee and sheet estimates, and prerequisite actions. 3 methodologies govern them: BIM Team Starter on market pre-assessment v2 at 2.3.0; 4D Pilot & Rollout Planner and CDE Setup Starter Check on market pre-assessment v2 at 2.1.0; BIM Documentation Starter on documentation sheet effort v1 at 0.4.0; and BIM Budget Starter on BIM modelling fee estimation v1 at 0.13.0. Each tool shows its own source date. Discipline modelers, area and sheet fees, and percentage-priced trades use visible assumptions. Team and budget outputs explain each BIM role's basic responsibilities. Unknown prices remain open while useful scope and next steps remain available.

Results distinguish your figures, supplier references, configurable starting allowances and self-reported conditions. No readiness score, automatic savings forecast or professional endorsement is implied. Source dates and limitations accompany each tool and its exports.

Five distinct kinds of evidence

These labels keep a sourced fact separate from an editable assumption. Every material rule or input must have a declared basis.

Fact
A directly verifiable statement, used within the scope of its source.
Evidence-based benchmark
An observed or published range with its context and transfer limitations.
Professional judgement
An explicitly labelled expert heuristic with a rationale and reviewer.
Configurable assumption
A visible choice or value that the user can review before calculating.
Unknown / needs validation
A gap in the evidence that cannot silently become a default or a confident answer.

Understand the basis

What has been reviewed?

3 preliminary methodologies · not externally reviewed

Each tool shows its method, sources, scope and software tests. Software checks do not establish professional suitability: independent review of these methods is still pending.

  1. Define the decision, users, inputs, units, and excluded uses.
  2. Record sources, rights, assumptions, and uncertainty.
  3. Validate typical cases, boundaries, invalid inputs, and unsupported scope.
  4. Obtain professional sign-off and record a review date before making any approval or endorsement claim.
  5. Publish the method version alongside the tool and its results.

Limitations

  • A methodology applies only within its declared scope.
  • An estimate does not establish a tender price, contractual obligation, or compliance determination.
  • Unknowns must be made visible and handled explicitly before a result can be trusted.
