Clashes caught too late, version confusion across disciplines, RFIs lost in email, a handover that takes weeks to pull together: if that sounds like your projects, the problem usually isn’t your team. It’s that most BIM collaboration tools expect you to bend your process around their workflow instead of the other way round.
At ByteGears, we build BIM collaboration platforms for UK architecture, engineering and construction firms, designed around how you actually coordinate work. Instead of off-the-shelf software with per-seat licensing and feature bundles you’ll never touch, you get a Common Data Environment that connects to the authoring and scheduling tools you already run, supports your ISO 19650 workflows, and that you own outright.
We’re a London-based development consultancy. We’ve spent enough time around UK AEC firms to know where the usual tools break down, and to be honest about when they don’t. If a mainstream cloud tool is the right answer for you, we’ll say so. This page is for the firms it isn’t.
Where off-the-shelf BIM platforms fall short
The big cloud platforms are capable, but they tend to cause their own problems for a growing UK firm:
- Per-seat pricing that explodes with headcount. Enterprise BIM collaboration suites are often priced in the high hundreds to low thousands of pounds per user per year. Cross 100-plus users and licensing quietly becomes your single largest software cost.
- Opaque, shifting pricing. Module bundling, “contact sales” quotes and product consolidation make it hard to know what you’re actually paying for, or what you’ll be paying next year.
- Workflow rigidity. Naming conventions, approval chains and access models are built around the vendor’s idea of best practice, not your appointment structure or your client’s CDE mandate.
- Clash and coordination gaps. Several popular collaboration tools have light native clash detection and lean on Navisworks, Solibri or BIMcollab to do the real checking, which means more licences and more handoffs.
- Integration friction. Connections to non-native authoring tools, scheduling systems and your ERP or cost software are often shallow, lossy or absent. Schedule updates in P6 don’t flow back to the model; site photos don’t sync without custom middleware.
- Hidden costs that don’t appear in the quote. Data migration, training, storage overage, API limits, hardware upgrades for large models and premium support all sit on top of the headline figure.
The result is workarounds, parallel spreadsheets, extra licences to cover the gaps, and a total cost of ownership that drifts well past the sticker price. Plenty of UK firms end up paying for things they don’t use while still missing the thing they actually need.
What we build instead
A ByteGears platform is a Common Data Environment shaped around your firm rather than a generic product you adapt to.
Built around your coordination process
We map your real workflow before any code gets written: how models are federated, how clashes get raised and assigned, what your approval chain looks like across consultants and clients, and what your naming and LOD conventions are. The platform fits that, rather than forcing a change in how your BIM manager has set things up.
Open standards at the core
We build on IFC for model exchange, BCF for issue round-trips and COBie for asset handover, so you stay interoperable with whatever authoring tools your team and your collaborators use. No lock-in to a single vendor’s ecosystem.
One-time cost, no per-seat fees
You pay a predictable development cost rather than a subscription that scales with headcount. Add a contractor or a whole new team and the licensing cost doesn’t move. Support is an optional package on top.
Built for ISO 19650 and the golden thread
Role-based access, version control, formal approval and sign-off workflows, and a tamper-evident audit trail come as standard. That structure supports ISO 19650 information management and the long-term record-keeping duties of the Building Safety Act, including COBie handover and retention of building information well beyond practical completion.
Integration with what you already run
We build dedicated connectors to authoring tools (Revit, Archicad, Tekla), scheduling systems (Asta Powerproject, Microsoft Project, Primavera P6), document storage (SharePoint, Microsoft 365), and your accounting or ERP system where model data needs to meet cost data. Where a vendor only offers a shallow plugin, we build the proper API layer.
Your choice of hosting
UK-hosted cloud for most work, or on-premise and hybrid deployment where data residency, air-gap requirements or very large federated models call for it.
A UK team behind it
Our London-based team handles implementation, data migration, role-based training, and a defined support period after launch, with retained support available afterwards.
Features we build into these platforms
The right mix depends on your projects. A typical build draws from:
- Common Data Environment: a single source of truth for models, drawings, specs, submittals and RFIs, with access control and full version history
- Federated model management: combine architectural, structural and MEP models, manage dependencies and apply partial updates without re-uploading everything
- Clash detection: rule-based geometric checks with tolerances and false-positive filtering tuned to your firm’s MEP clearance and sequencing standards
- Issue tracking with BCF: defects and conflicts tied to model coordinates, assigned with status tracking and exportable as BCF for round-trips with external tools
- Approval and sign-off workflows: review chains that match your actual appointment structure across disciplines, consultants and clients
- Audit trail: every create, edit and delete logged with user, timestamp and before/after state, suitable for ISO 19650 and golden-thread evidence
- Mobile field access: model viewing, issue reporting and photo markup for site teams, with reliable sync back to the office
- 4D scheduling links: connect models to programme data to visualise sequencing, site logistics and temporary works
- Reporting dashboards: clash counts, approval backlog, RFI status, model completeness and project health in one place
- UK standards templates: pre-configured for COBie deliverables, Uniclass classification and NBS specification linking
How the build works
We start small and prove it on a real project before scaling. Rolling a new tool out to every live job at once is one of the most common ways a BIM platform implementation goes wrong.
Phase 1: Discovery and planning (2-3 weeks)
Process mapping workshops with your BIM manager and project leads, technical requirements, integration points, and a review of the compliance and data-residency rules your projects work under.
Phase 2: MVP development (4-6 months)
Agile sprints with fortnightly demos, building the core: model viewing and version control, issue tracking with BCF export, role-based permissions, an audit trail, basic clash checking and the first one or two integrations. You get early access to features as they land.
Phase 3: Pilot and rollout
We deploy the MVP to a pilot project so the team can use it on real work, refine the process, and surface integration issues before they affect the wider portfolio. A staged rollout follows, with data migration support.
Phase 4: Phase 2 enhancements and support
Once the platform is stable, later work typically adds configurable clash rules, 4D scheduling links, the reporting suite, richer mobile editing and wider integrations. Every build includes a defined support period, with retained support available afterwards.
What it costs, and what you own
Custom development is an upfront project cost. On a small team that figure can look high next to a cheap cloud subscription, and we won’t pretend otherwise. The argument changes with scale.
Enterprise BIM collaboration suites are commonly priced in the high hundreds to low thousands of pounds per user per year. For a 100-plus user firm that adds up to a substantial recurring spend over three to five years, before counting implementation, data migration, storage overage, API limits and premium support. A bespoke platform carries no seat fees, so the total cost flattens as you grow, and you own the source code and data outright rather than renting access.
The price of your build depends on integration count, model complexity, user roles and permission tiers, and your compliance requirements. Our free consultation gives you a real budget figure for your situation, with no obligation, and an honest view of whether a custom build is the right call at all.
Who uses these platforms
- Architecture practices: coordinated design reviews, client presentations, Building Regulations evidence, and heritage or retrofit work where tight spaces make clash detection critical.
- Engineering consultancies: multi-discipline coordination across structural and MEP, steel models exported to fabricator software to cut field rework, and civil and infrastructure projects with 4D scheduling for temporary works.
- Main contractors: subcontractor coordination, construction sequencing, site logistics planning and early hazard identification.
- Specialist contractors: trade-specific model authoring and fabrication detailing federated into the wider model.
- Project and programme managers: tracking programmes against model milestones, with RFI and submittal status in one place.
- Facilities managers: COBie handover, as-built asset information and maintenance planning across a 30-to-50-year asset life.
- Public sector and education: ISO 19650-mandated CDEs for NHS, council and campus projects, with audit trails and UK data residency.
Because it’s built for you, the platform matches your sector’s deliverables and workflows rather than the generic case.
Common Questions About Custom BIM Collaboration Platforms for UK AEC Firms
How does a custom build compare on cost to BIM SaaS?
A custom platform is an upfront project cost rather than a per-seat subscription. On a small team that figure can look high next to a cheap cloud tool. The argument changes as you grow: enterprise BIM collaboration suites are often priced in the high hundreds to low thousands of pounds per user per year, so a 100-plus user firm can spend well into six figures over three years before counting implementation, storage overage and integration work. A bespoke platform has no seat fees, so the total cost flattens as headcount rises. We give you a real budget figure for your situation at the consultation stage.
Should we just stick with off-the-shelf BIM software?
Often, yes. If you run small-to-medium projects with two or three disciplines, fewer than 30 people working concurrently, fairly linear design-review-approve workflows and little integration with other systems, a mainstream cloud tool is usually the sensible choice and we will tell you so. Custom makes sense when you have complex federated models, non-standard approval chains, tight integration with ERP, scheduling or cost systems, regulated-sector audit and data-residency rules, or a headcount where per-seat licensing has become the main cost driver.
What's the typical timeline for a custom build?
A working MVP, covering model viewing, version control, issue tracking with BCF export, role-based permissions and an audit trail, usually takes around four to six months and goes live on a pilot project. A second phase adding advanced clash rules, 4D scheduling links, reporting dashboards and wider integrations typically follows over the next four to eight months. We run a pilot before any full rollout to avoid disrupting every live project at once.
Will it work with Revit, Archicad, IFC and our scheduling tools?
Yes. These platforms are built around open standards: IFC for model exchange, BCF for issue round-trips and COBie for asset handover. We commonly connect to authoring tools such as Revit, Archicad and Tekla, scheduling systems including Asta Powerproject, Microsoft Project and Primavera P6, document storage in SharePoint or Microsoft 365, and accounting or ERP systems where you need model data linked to cost. We build dedicated connectors and API layers rather than relying on whatever a vendor marketplace happens to offer.
Can you meet ISO 19650 and Building Safety Act requirements?
We build the platform as a proper Common Data Environment: role-based access, version control, formal approval and sign-off workflows, and a tamper-evident audit trail recording who changed what and when. That structure aligns with ISO 19650 information management and supports the "golden thread" duties under the Building Safety Act, including long-term retention of building information and COBie handover. We are software engineers, not your appointed Information Manager, but the platform gives that role the controls it needs.
Where will our project data be hosted?
Your choice. We can deploy to UK-hosted cloud infrastructure, which suits most NHS, local authority and education work, or run an on-premise or hybrid deployment where data residency, air-gap or extreme model sizes demand it. Data handling is UK GDPR-compliant, with encryption in transit and at rest, access logging and a clear data processing agreement.
Do you provide training and support after launch?
Yes. We deliver role-based training, since a BIM manager configuring permissions and a site team using the mobile app need very different things, plus a knowledge base and on-site or remote workshops. Every build includes a defined support period after go-live. After that you can move to a retainer, commission fixed-scope enhancement projects, or take on day-to-day administration yourselves. You own the source code and data either way.
