PriMus IFC — 5D BIM Cost Estimation Software
Your BIM Model Already Has the Quantities. Let the Software Find Them.
PriMus IFC is the 5D BIM software that extracts quantities automatically from any IFC BIM model — using AI to identify entity types, generate measurement rules, and produce a complete BIM quantity takeoff that updates every time the model changes. From model to BoQ in minutes, not days.
Certification Callout buildingSMART International® Certified — IFC quantity takeoff verified to the global openBIM standard.
Trust Statement Before technology, there has to be a relationship. Isotech works alongside quantity surveyors, estimators, and commercial teams across the GCC — coaching and supporting your adoption of 5D BIM workflows at every step.
Value Pillars
AI-Powered BIM Quantity Takeoff
The first automatic BIM quantity takeoff software with Artificial Intelligence — identifying IFC entity types in your model, generating measurement rules automatically, and delivering a complete quantity schedule without manual remeasurement.
IFC-Based Estimating. Every Authoring Tool Supported.
Open IFC files from Revit, ArchiCAD, Allplan, Edificius, and any IFC-certified tool. PriMus IFC is certified 5D BIM software that works with any model — not just models from a single platform.
BIM to BoQ. Always Current.
When the model changes, the quantities update. The BoQ always reflects the current design — not the version from last week's coordination meeting.
Reusable Templates. Repeatable Workflows.
Create quantity takeoff templates once and apply them across multiple projects. Turn 5D BIM cost estimation from a one-time task into a consistent, repeatable commercial process.
What Is 5D BIM?
What Is 5D BIM — and Why Does It Change Cost Estimating?
BIM delivers three spatial dimensions by default. Adding the fourth dimension — time — gives you a construction programme. Adding the fifth dimension — cost — gives you 5D BIM: a live connection between the geometric model and the project's quantities and costs.
In traditional estimating, the design changes and the estimate lags behind. In 5D BIM cost estimation, cost is embedded in the model itself. Every change to a wall length, slab area, or structural element immediately updates the associated quantities and the connected cost estimate — automatically.
The practical result is faster estimates, more accurate BoQs, and cost plans that stay aligned with the design at every stage of the project. For GCC project teams working under programme pressure and government procurement scrutiny, this is not a workflow improvement. It is a competitive and compliance advantage.
PriMus IFC is the 5D BIM software that makes this workflow practical — connecting the IFC model to a complete quantity takeoff and feeding it directly into the PriMus cost estimating environment.
How PriMus IFC Works
AI-Powered IFC-Based Estimating. Automatic. Visual. Always Updated.
Open any IFC file in PriMus IFC. The AI engine analyses the model, identifies every entity type — walls, floors, columns, beams, doors, windows, MEP components — and guides you through creating the measurement rules needed for a complete BIM quantity takeoff. Once the rules are set, the takeoff runs automatically across the full model.
Every entity is accounted for. Every quantity is traceable. Every measurement is visually verifiable — click on any item in the quantity schedule and the corresponding elements are highlighted directly in the 3D model view, so you can confirm exactly what has been measured and what it represents.
When the design team updates the model and a new IFC file is issued, PriMus IFC processes the updated file against the same measurement rules and delivers an updated quantity takeoff — reflecting the changes without manual remeasurement.
The resulting quantities feed directly into PriMus for cost estimate and BoQ production, completing the full BIM to BoQ workflow in one connected process.
Benefits of 5D BIM Modeling
The Benefits of 5D BIM Cost Estimation Are Measurable from the First Project.
With BIM cost estimating, quantities are extracted from the model in minutes rather than measured manually over days. The time saved on every project is significant — and the accuracy is higher because the source is the model, not a human measurement.
The most common source of estimating error is working from an outdated drawing set. In an IFC-based estimating workflow, the cost estimate is always connected to the current model. Design changes flow into the BoQ automatically — without a separate remeasurement cycle.
Quantity takeoff templates created in PriMus IFC can be applied to every subsequent project of the same type. The measurement rules you develop for a residential tower, an infrastructure project, or a commercial development become a reusable asset — making every future estimate faster and more consistent.
Every quantity in the BIM quantity takeoff is traceable to a specific model element. For government procurement in the GCC — where BoQ documentation requires clear audit trails — this traceability is both a compliance requirement and a professional standard. PriMus IFC meets both.
Who It Is For
5D BIM Software for Quantity Surveyors, Estimators, and Commercial Teams.
PriMus IFC is the 5D BIM cost estimation software for every professional responsible for construction cost at any stage of the project — from the quantity surveyor producing the pre-tender BoQ to the commercial manager tracking costs through construction.
For quantity surveyors, PriMus IFC replaces manual takeoff with automatic BIM quantity takeoff — freeing time from measurement and redirecting it toward analysis, value engineering, and commercial advice.
For estimators and project designers, IFC-based estimating means cost plans that update with the design — eliminating the re-estimating cycle that consumes commercial resources on every design iteration.
For construction companies tendering government contracts in the GCC, 5D BIM software produces the auditable, model-connected BoQ documentation that public procurement increasingly requires.

Questions Worth Answering Up Front.
What is 5D BIM and how does PriMus IFC deliver it?
5D BIM adds cost as the fifth dimension of a BIM model — connecting the geometric model to quantities and cost estimates so that every design change automatically updates the associated BoQ. PriMus IFC is the 5D BIM software that delivers this by opening an IFC file, using AI to identify entity types and generate measurement rules, and producing a complete BIM quantity takeoff directly from the model. Quantities feed into PriMus for full cost estimate and BoQ production — completing the BIM to BoQ workflow without manual remeasurement.
What BIM authoring software does PriMus IFC support?
PriMus IFC is IFC-based estimating software that works with any IFC-certified BIM authoring tool — including Revit, ArchiCAD, Allplan, Tekla, Edificius, and all others that export to IFC. Because it is certified by buildingSMART International, its IFC quantity takeoff capability is verified against the international standard — giving confidence in the accuracy and reliability of the takeoff regardless of which tool produced the model.
How does the BIM quantity takeoff update when the model changes?
When a new IFC file is issued following a design change, PriMus IFC applies the existing measurement rules to the updated model automatically. The quantity takeoff updates to reflect the changes — without manual remeasurement or rule reconfiguration. This dynamic update is the core operational advantage of IFC-based estimating over traditional takeoff methods: the cost estimate stays aligned with the current design at all times.
Can quantity takeoff templates be reused across projects?
Yes. Templates in PriMus IFC capture the full measurement rule logic for a given project type and can be saved and applied to subsequent IFC models. For commercial teams managing a consistent project portfolio — residential, commercial, or infrastructure — reusable templates make every future BIM quantity takeoff faster, more consistent, and aligned to established measurement standards.
