Software for construction planning and BIM. Analyse and correct Primavera P6 programmes, coordinate Revit and Navisworks models, and share both with the whole project team.
Most projects keep the programme and the model in separate tools, owned by separate teams. We connect them, so a date in the programme and an element in the model mean the same thing.
Each model element carries the Activity ID that builds it, so progress, clashes and quantities line up with the programme.
Both engines run on your own machine and work offline. Nothing is uploaded unless you publish it, and your source files are never changed.
Every number on screen is computed from your file, and our progress figures match P6 to within about 0.05% on real projects.
Each engine is a complete desktop tool for the people who build the programme or the model. Each viewer opens that work up to everyone else on the project, read-only.

The programme says week 14. The site should agree.
PBM Dynamics keeps the programme, the model and the site on the same data date, so every team works from the same facts.
Dense MEP coordination on fast-track programmes.
Repeating floor cycles, tracked level by level.
Long programmes with many interfaces and contractors.
Heavy structure, plant and tight shutdown windows.
The engines run on your own machine and work with the network cable out. Nothing is uploaded until you publish a project to PBM Cloud, and your .xer and .rvt files are never changed.
Three desktop engines that do the work on your PC, and three online viewers that share it with your employer, client and project team through PBM Cloud.
Engines are where the work is done, offline, on your PC. When you choose to share, the engine publishes to PBM Cloud and the matching viewer opens it in any browser.
The engines keep working with no connection. When the work is ready for others, publish it to a PBM Cloud project and send a link. Your employer, the client and other stakeholders open it in a browser, with no install and no licence.
You decide what is published and who can see it. Nothing is uploaded automatically, and your .xer, .rvt and .nwd files are never changed.
Licensing never gets in the way of site work. Each desktop app checks in when it can, and keeps working when it can't.
On first run the app binds a free seat to the machine and receives a signed token.
The app checks the token locally. No connection is needed for 30 days.
Any time the app is online it renews the token for another 30 days.
Deactivate a machine in the app or from your PBM Cloud account to use the seat elsewhere.
Link your P6 programme to your models by Activity ID, and see the model coloured by how the work is actually going.
An early build of 4D Engine in split view. The left half shows the model as built at this programme update, the right half shows where the baseline said it should be, and both move together as you orbit or step through time.
A three-storey frame with 13 activities. Each element is tagged with the Activity ID that builds it. It turns blue while that activity is under way and paper white once it is complete.
Open your P6 .xer or P6 database. The imported file is never modified.
Click “Send to BIM Engine” in Revit or Navisworks. Every send is versioned.
Tag elements by selection or search set, and review the AI's suggested matches.
Run health and clash checks, colour the model at a data date, and issue the report.
The construction sequence online for everyone on the project. 4D Engine publishes the integration, and anyone with the link plays the model coloured by the programme.
Send the model, the programme and the Activity ID links between them to a PBM Cloud project.
Each new programme update re-colours the shared model, actual against baseline.
Anyone on the project scrubs the timeline at any data date. No engine, no P6 and no Revit needed.
Analyse, correct, report and present Primavera P6 programmes. A complete desktop tool for planners and project controls.
Planning Engine opens Primavera P6 programmes and tells you what the dates really depend on. It checks programme quality, explains delays, fixes the XER, and turns the result into reports your client will read.
Federate, coordinate, clash-check and analyse every model on site. A complete desktop tool for BIM teams.
BIM Engine takes the models your project already has and puts them in one fast, local viewer. Coordinate disciplines, run clash tests, manage issues and pull quantities, all without changing a single source file.
The programme online for everyone who doesn't run P6. Planning Engine publishes each update from your PC, and your employer, client and site teams open it in a browser.
Connect a local project to a PBM Cloud project once. The analysis keeps running on your PC.
Send the new data date with its dashboard, health check, S-curves and baseline comparison. You choose what is included.
Your employer, the client and consultants open the Planning Viewer link. No P6, no install and no licence.
The model online for everyone on the project. Share it straight from the Revit or Navisworks add-in, or publish a federation from BIM Engine, then send the link.
Send the model straight to BIM Viewer from the same add-in you use for BIM Engine. No export step.
The model opens in any browser with its levels, categories and every Revit property. No modelling licence needed.
Paste the link into BIM Engine on your desktop to open the same shared model next to your local work.
Where programme and model most need to agree: fast, dense and heavily coordinated projects.
Dense MEP coordination on fast-track programmes.
Repeating floor cycles, tracked level by level.
Long programmes with many interfaces and contractors.
Heavy structure, plant and tight shutdown windows.
Estimate the review and coordination time PBM could give back to your team.
Set the sliders to match your projects. Every result below comes only from these assumptions, so change them until they look like yours.
An illustration, not a quote. Book a demo and we'll run the numbers on one of your own programmes.
Pay for the engines your team works in. Everyone you share with opens the Planning Viewer and BIM Viewer free, with no account and no licence.

Planning, BIM and 4D on one seat, for the people who work across all three.
Billed monthly
Start a 30-day trialVolume pricing across all three engines, one company account for licences and seats, invoice billing, and onboarding and training for your planners and BIM teams.
No. Anyone with a share link opens the Planning Viewer or BIM Viewer in a browser. Seats are only for the people who work in the engines.
The trial is the full product. At the end, choose a plan to keep working; nothing you made in the trial is lost.
Yes. Deactivate the seat in the app or from your PBM Cloud account, then activate it on the new PC.
Only to activate, and then once every 30 days to check in. Everything else runs on your PC.
Only what you choose to publish to PBM Cloud. Your .xer, .rvt and .nwd files are never uploaded or changed.
Not yet. They are indicative while the platform is in preview. Final prices, currencies and taxes will be confirmed at launch.
We build software for the people who plan and coordinate construction projects.
PBM Dynamics stands for Project BIM Management. We build software for planners, BIM coordinators and project managers who need the programme and the model to agree.
How PBM Dynamics handles your data, and the terms for using the engines and PBM Cloud.
Draft for legal review before launch. Bracketed items are still to be filled in. Last updated 3 October 2026.
PBM Dynamics ([company legal name and registered address]) makes three desktop engines (Planning Engine, BIM Engine and 4D Engine) and PBM Cloud, the online service where you share their results. This section says what we collect, why, and what you can ask us to do with it.
Your programmes, models and analysis stay on your PC. Nothing is sent to us unless you choose to publish it to PBM Cloud. The only automatic contact is the licence check: an engine confirms its licence when you activate it and at least once every 30 days after that, sending your account, the licence and an identifier for the device.
A PBM Cloud project is visible to its members and to anyone holding one of its share links. A share link is read-only, can expire, and the project's owner or editors can withdraw it at any time. PBM Dynamics staff see project details only when they need to for support or security.
PBM Cloud runs on [hosting provider and region]. The website is served by [website host], and emails are delivered through [email provider]. We do not sell your data, and the website uses no advertising or analytics trackers. The website and the PBM Cloud app keep your theme choice, and when you sign in your session, in your browser's local storage.
Account, licence and project data are kept while your account is open. Published items are kept until you remove them or close the project. Security records are kept for [retention period]. When you close your account we delete or anonymise your data within [period], except where we must keep records by law.
You can ask to see, correct, export or delete your data, or object to how we use it, by writing to [privacy contact email]. You can remove published items and withdraw share links yourself in PBM Cloud at any time.
[Applicable data protection law and authority to be confirmed, e.g. Egypt's Personal Data Protection Law No. 151 of 2020, Saudi Arabia's PDPL, and the GDPR for customers in the EU.]
These terms apply when you use a PBM Dynamics engine or PBM Cloud. By activating an engine or creating an account you agree to them.
You keep all rights to the models, programmes and other material you publish. You give us permission to store it and show it to the people you share it with, only to provide the service. You confirm you have the right to publish what you upload, and that sharing it does not break an agreement with your employer or client.
Do not try to get around licensing, reach data you have not been given access to, disrupt the service, or reverse-engineer the software except where the law allows it.
We work to keep PBM Cloud available but do not guarantee it is uninterrupted. We may change or improve the software and these terms; we will tell account holders about material changes before they take effect.
[Payment methods, billing period, cancellation and refund terms: to be set once payments are decided.]
The engines compute from the files you give them; you remain responsible for decisions you make with the results. [Limitation of liability, warranties and indemnity: for legal review.]
You can close your account at any time. We may suspend an account that breaks these terms, telling you why where we can.
These terms are governed by [governing law and courts]. Questions: [contact email].
Send us a P6 programme or a Revit or Navisworks model. We'll walk your team through the result on your own data in a 45-minute session.
