Production, coordination and governance to ISO 19650, delivered as a full BIM team for consultants, contractors and developers. No internal hire, no management overhead.
Documentation packages produced to your BEP while your architects hold the design line, including the survey-led modelling heritage work demands.
Explore Build-sideCoordination and shop drawings for sites inside protected fabric, where the existing structure leaves no tolerance for on-site rework.
Explore Owner-sidePortfolio information governance with one EIR and one CDE discipline, so each asset hands over the same quality of data.
ExplorePrague's senior modellers are spread across the same short list of practices. We bring our own.
Office refurbishments inside protected fabric and new commercial quarters at the city's edge both need senior production staff the local market cannot supply at once. JES fills the gap with a working team, not a vacancy: production from our floor, coordination on European hours, Author-Checker-Approver review on everything.




























Each service arrives staffed, gated and tracked: ISO 19650 setup at the front, Author-Checker-Approver review in the middle, ERP visibility throughout.

Modelling and drawing production across disciplines, federated and clash-checked before any package reaches your site office.
Explore service
4D and 5D studies that reduce sequencing and cost risk on schemes where the existing structure limits the options.
Explore service
Your EIR turned into an enforced working standard: CDE administered, naming checked, exchanges verified.
Explore
Asset models with operational data structured for the FM provider, covering retained heritage fabric alongside new systems.
Explore
Quantities taken from the coordinated model so cost plans and valuations stay aligned with the design.
Explore
Scan-verified records documenting what was built, on projects where the starting condition was never properly drawn.
ExploreEverything from scan to handover data, delivered by one supplier instead of a hiring market that cannot supply it.
Cross-discipline Revit production to one standard, with federation and clash detection as routine steps.
Families built to your office library, including the non-standard profiles historic buildings require.
4D sequencing where site logistics are constrained, 5D cost linkage throughout, 6D data when performance targets call for it.
Fabrication-ready shop drawings coordinated against both the design model and the surveyed structure.
Scan to BIM for older stock: point clouds processed into models accurate enough to design against.
Historic 2D documentation rebuilt as structured models, giving heritage assets a reliable geometric record.
CAFM-ready asset data compiled during delivery, structured around how the building will be operated.
Model-derived quantities under your measurement rules, keeping the cost plan aligned with the current design.
Every JES deliverable moves through a fixed Author-Checker-Approver gate, tracked in the CDE. The same standard whether it's engineer 3 or engineer 250.
Run without the gate and the failures escalate to your most senior people: reissued packages, on-site clashes, audit findings and incomplete handovers all land on the same overstretched team. JES contains them procedurally, with named review on every file and the trail in ERP.
A national museum, metro systems and resort destinations in the Gulf, taken through ISO 19650 delivery. The same review chain now serves Central Europe.

Read the casePackages issued to programme from a clash-resolved federated model, protecting site weeks heritage constraints have already made scarce.
The ERP dashboard replaces status meetings: every deliverable, its reviewer and its history, visible without asking.
ISO 19650 established at kickoff, with information requirements agreed and the CDE configured before modelling starts.
Why "coordinated" models still cause site rework, and the handoff that fixes it.
ReadThe difference between a filed document and a working agreement is five sections.
ReadZero hard-clash is table stakes. Here is the tolerance standard we hold a federated model to before sign-off.
ReadWhen quantities come straight from the model, variations stop being arguments and become deltas.
ReadRetrofitting an as-built at practical completion is a tax. Updating it weekly is a habit.
ReadBoth. We produce the models and drawings across disciplines and we govern the standards: your EIR turned into an enforced working standard, the CDE administered, exchanges verified. One accountable team does both. You are not managing a consultancy that advises and a separate shop that draws, which matters when the same senior people are already stretched.
Yes. You get a dedicated outsourced BIM team under one named lead, producing from our floor, so protected-fabric refurbishments no longer wait on a stretched local market that cannot supply senior staff to two project types at once. Capacity scales against the programme, not a permanent hire. Coordination runs on European hours with review on every file.
Yes. Our consultants embed in your delivery, set the BEP and LOD schedule and hold the work to ISO 19650, coordinated on European hours. One named lead stays accountable across the programme, and every file clears Author-Checker-Approver review before issue, so your architects hold the design line while the standard holds behind them in the ERP.
Yes. We run laser scan to registered point cloud to a coordinated record model accurate enough to design against, for older stock whose starting condition was never properly drawn. Architectural, structural and MEP coordinate against that base. On heritage refurbishment it covers retained fabric alongside the new systems in one dataset.
Architectural, structural and MEP. We author them in Revit and federate them in Navisworks with regular clash cycles on one model, authored, checked and approved against the BEP before issue. On sites inside protected fabric the existing structure leaves no tolerance for on-site rework, so conflicts are resolved in the coordinated model before any package reaches your site office.
Cost follows scope, the disciplines involved, the LOD you need and the programme length, so we scope each engagement to the actual work rather than a flat rate. A protected-fabric refurbishment carries more than a new commercial quarter. The zero-cost pilot on one package lets you test the gate and the output first.
The full ACA framework PDF, the Responsibility Matrix template, and the EIR / BEP checklist we use on every project.
We'll walk you through a live ERP dashboard from an active project and you'll walk away with our ACA template, whether or not we work together.
We run the ACA framework on a single package. You get ERP visibility from day one. Zero-cost pilot, capped scope, clear exit.
