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 produced to your standards and your graphic conventions, so the package still reads as yours. Your team sells design, ours produces the drawings behind it.
Explore Build-sideCoordination models and trade drawings for contractors delivering at home and abroad, resolved against every discipline before mobilisation.
Explore Owner-sideConsistent information delivery across mixed consultant teams, with the EIR enforced as a working document through the CDE.
ExploreLean Portuguese studios win work that demands the output of much larger firms. We add the production depth.
A lean studio can hold the design intent on a large project, but the drawing list outgrows the team. JES carries the production: 260+ engineers behind yours, coordinated through our Ortenberg office on your working day, with three-stage QA on every file.




























Every line of scope runs through the same QA gates, the same ERP tracking and the same ISO 19650 setup, whether the project sits in Porto or abroad.

Discipline models, federation and drawing production at export quality. The set you issue to a foreign client survives that client's audit.
Explore service
4D and 5D analysis that lets your practice discuss programme and cost with contractor-grade evidence.
Explore service
We administer the CDE, hold the naming convention and run the exchanges, so a two-person BIM function performs like a department.
Explore
Asset information models prepared for the operator from the outset, so handover means a usable dataset rather than a folder of PDFs.
Explore
Quantities lifted straight from the coordinated model, giving your cost consultants one defensible source for BOQs and variations.
Explore
Scan-verified record models that document the building as it stands, not as the design assumed.
ExploreEight services from one supplier, so your studio can take international scope without growing its payroll.
Revit production across all major disciplines, run to a single documented standard from first model to final issue.
Component libraries built to your office template, with the parametric behaviour and LOD your projects need.
Sequencing, cost and performance dimensions added to the model where they sharpen decisions: 4D, 5D and 6D as the brief requires.
Shop drawings coordinated and dimensioned for the fabricator, checked against the federated model before they leave us.
Point clouds from survey partners converted into dependable existing-condition models for renovation work.
Flat 2D archives redrawn as structured 3D models, so older documentation becomes usable project data.
Operations-ready asset data assembled during delivery, structured for CAFM import at handover.
Model-based measurement aligned to your cost framework, keeping estimates current as the design develops.
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.
Lose that control and the costs stack: missed issue dates, conflicting trade drawings, a BEP that fails review and asset data missing at completion. In a lean practice each one lands on the same few desks. The JES gate names an author, a checker and an approver on every file, logged in ERP.

Read the caseDrawing sets delivered against the agreed programme from a clash-cleared federated model, so issue day stops being a risk event.
Progress is read, not requested. ERP dashboards show every deliverable's position and its full Author-Checker-Approver history.
ISO 19650 in place before modelling begins: EIR interpreted, BEP authored, CDE structured.
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 discipline models, federation and drawings and we govern the standards behind them: the CDE administered, the naming convention held, the exchanges run. One accountable team does both, so a two-person BIM function performs like a department. You are not managing a consultancy that advises beside a separate shop that draws.
Yes. You get a dedicated outsourced BIM team under one named lead, 260+ engineers behind yours, so a lean studio can hold a large project without the drawing list outgrowing it. Capacity scales against the programme, not a permanent hire. Coordination runs through our Ortenberg office on your working day, with three-stage QA on every file.
Yes. Our consultants embed in your delivery, set the BEP and LOD schedule and hold the work to ISO 19650, coordinated through our Ortenberg office on your working day. One named lead stays accountable across the programme, and every file clears the author, checker and approver gate before the set you issue meets a foreign client's audit.
Yes. We convert survey-partner point clouds into a scan-verified record model that documents the building as it stands, not as the design assumed. Architectural, structural and MEP coordinate against that base. For the renovation work behind much of Portugal's pipeline, it gives your team a dependable existing condition to start from.
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. Coordination models and trade drawings are resolved against every discipline before mobilisation, for contractors delivering at home and abroad where the set has to survive a client's audit.
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 day rate. A large project's drawing list carries more than a single package. The zero-cost pilot on one package lets you see the output and the QA 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.
