How can we help you?
How ForensicBIM values IFC model data, how the audit and the numbers are built, and how your files are kept secure. Practical guides for file limits and the 3D viewer are at the bottom.

3 key articlesWhy BIM data is worth less on the balance sheet than the industry thinks
Accounting rules start from cost, not expected savings, and model data has no second-hand market. What that means for the carrying amount, with worked examples under IAS 38, GASB 51 and RJ 210, and how the rules compare across Germany and other EU countries, the UK, the US, Japan, China and Australia.
Valuation methodology: how the numbers are built
What is being valued, the accounting and valuation standards behind it (IAS 36, IAS 38, IFRS 13, IVS), how estimates are calibrated against expert judgement, and how their accuracy is checked.
Encryption: how, where and what we encrypt
TLS 1.3 in transit, AES-256 at rest in the storage region you choose, SHA-256 integrity checks on every uploaded file, and customer-managed keys for Enterprise.

Valuation & accounting
5 articlesWhat the numbers mean, and how model data can be recognised and capitalised on the balance sheet.
The eleven numbers: the data value ladder
The eleven quantities that get called ‘the value of the data’, from reproduction cost to carrying amount. Cost side versus utility side, deprival value, and when data can be recognised on the balance sheet.
Which number answers which question?
A decision guide for asset owners, controllers, BIM managers and auditors: which figure to use for the balance sheet, an impairment test, a maintenance budget or a rebuild estimate.
Why ForensicBIM works with IFC
IFC (ISO 16739) stays readable for decades. Proprietary formats carry ongoing licence costs and can drop to zero value once the software stops supporting them.
Does AI change the value of IFC data?
Why faster recreation with AI doesn’t change the carrying amount, where the value in operations sits, and why AI depends on reliable data. Includes the Waternet Amsterdam case.
ForensicBIM and the EU BIM Task Group CBA method
How the EU cost-benefit handbook’s pre-tender estimates relate to ForensicBIM’s audit and valuation of the IFC files actually delivered.
Methodology & checks
6 articlesWhere the figures come from, how sure they are, and what the audit checks in every file.
The risks of complex IFC geometry types
Why geometry can follow the IFC standard yet still fail on import, why data gets lost, and why forensicBIM measures downstream risk rather than mere validity.
Methodology overview: data, experts and standards
The benchmark of real IFC models, the expert reviews, the savings research and the accounting standards behind every score, valuation range and savings estimate.
What we check, and why
Around 50 automated checks across validity, structure, geometry, information and consistency, plus official buildingSMART validation, georeferencing, the 3D viewer and the geometry heatmap.
How sure is the estimate? Statistical confidence explained
What the confidence figure on the valuation page measures, why it doesn’t move when you change the hourly rate, and how to raise it.
What’s in the hourly rate?
What a blended rate is made of (wages, employer contributions, software licences, overheads) and which of those costs each accounting standard lets you count.
Quality badges
The badges an IFC file can earn, the criteria behind each one, and how to share them.
Security & privacy
3 articlesWhere your files are stored and processed, which controls protect them, and what happens when you delete them.
SOC 2 and ISO/IEC 27001: where we stand
The controls we run, how they map to SOC 2 and ISO/IEC 27001, and what an independent audit has not yet confirmed. Policies and evidence are available on request.
Trust centre: data residency and GDPR
Files are stored and processed only in the region you choose: the Netherlands, Iowa, London, Singapore, Hong Kong, Sydney, Tokyo or São Paulo. Plus our NIST CSF 2.0 alignment and approach to GDPR.
Privacy: deletion, retention and model reuse
What deleting an analysis or your account removes, how long records are kept, and how to opt out of model reuse in Settings.
Platform & support
5 articlesUploading files, using the 3D viewer, plans and pricing.
Frequently asked questions
Short answers on files and analysis, scores and valuation, privacy, sharing, downloads and deletion.
