Production, coordination and governance to ISO 19650, delivered as a full BIM team for consultants, contractors and developers. No internal hire, no management overhead.
Existing-condition models and intervention packages for buildings with no trustworthy drawings. Your design starts from measured geometry.
Explore Build-sideTrade coordination for sites squeezed between party walls and live streets, where conflicts have to be resolved in the model first.
Explore Owner-sideOne information standard across acquisition surveys, works packages and operator handover, so a portfolio reads as one dataset.
ExploreParis work means existing structure, tight sites and drawings that predate the project. We model from the scan.
With Grand Paris-era infrastructure absorbing much of the region's BIM capacity, practices on urban plots and historic conversions compete for the staff who remain. JES delivers the team instead: production on our floor, coordination on your hours, your conventions throughout. Survey data in, coordinated record models out.




























Whether the input is a point cloud or a design model, every service passes the same QA gates, the same ERP tracking and the same ISO 19650 configuration.

Modelling and drawing production for retrofit and new-build, coordinated against existing structure captured by scan rather than assumed from archive.
Explore service
4D sequencing for constrained urban logistics and 5D cost control for scopes where every square metre is contested.
Explore service
CDE governance, exchange management and convention compliance run continuously, so the standard holds beyond any single project meeting.
Explore
Asset models structured for operations from the start, carrying the existing fabric and the new intervention in one dataset.
Explore
Quantities pulled from the coordinated model, including the demolition and retention scopes retrofit estimating usually approximates.
Explore
Scan-verified record models that close out the works: deviation flagged during construction, the final record matching the building.
ExploreFrom laser scan to FM dataset, one supplier carries the whole scope, so your project never queues behind a missing specialism.
Multidiscipline Revit production under one modelling standard, in new structure and historic fabric alike.
Custom Revit families for the retrofit conditions standard libraries never cover, built to your naming and LOD rules.
4D logistics rehearsal for tight urban sequencing, 5D cost linkage and 6D performance overlays where targets demand them.
Shop drawings coordinated against scanned existing structure as well as the design model, issued at fabrication tolerance.
Scan to BIM as a core service: point clouds processed into accurate, queryable models of existing buildings.
Archive plans and 2D records reconstructed as working 3D models, often the first reliable geometry a building has had.
Operational data assembled through delivery and handed over CAFM-ready, covering retained fabric as well as new plant.
Model-based take-off across demolition, retention and new work, giving cost plans a measured foundation.
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.
Without those controls, retrofit projects fail in known ways: inaccurate surveys, trades clashing inside historic structure, BEP non-conformities at audit and record models that never reflect the works. JES answers with procedure: every file authored, checked and approved by name, tracked in ERP from survey to closeout.

Read the caseIssue-ready packages from a federated model anchored to scan data, so what is drawn matches what is standing.
An ERP dashboard carries each deliverable's status and full review chain, available before you ask.
ISO 19650 from day one of the commission: EIR interpreted, BEP written, CDE structured, audits passed on evidence.
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 and we govern the standards: CDE governance, exchange management and convention compliance run continuously. One accountable team does both, so the standard holds beyond any single project meeting. You are not managing a consultancy that advises and a separate shop that draws to your conventions on a contested urban plot.
Yes. You get a dedicated outsourced BIM team under one named lead, producing on our floor and coordinating on your hours, so historic conversions no longer compete for the staff Grand Paris leaves behind. Capacity scales against the programme, not a permanent hire. Survey data goes in, coordinated record models come out, your conventions kept throughout.
Yes. Our consultants embed in your delivery, set the BEP and LOD schedule and hold the work to ISO 19650, producing on our floor and coordinating on your hours. One named lead stays accountable across the programme, keeping your conventions throughout so the standard holds beyond any single project meeting on a constrained Paris plot.
Yes. We run laser scan to registered point cloud to a coordinated record model, so retrofit design starts from measured geometry rather than assumptions drawn from archive. Architectural, structural and MEP coordinate against that base. On historic conversions the model captures existing fabric and the new intervention in one dataset, deviation flagged during the works.
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 squeezed between party walls and live streets, trade conflicts are resolved in the model first, because on a Paris plot there is no room to resolve them otherwise.
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 historic conversion carries more than an urban infill plot, including the demolition and retention scopes. The zero-cost pilot on one package lets you test 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.
