BIM modelling, 4D simulation and 3D experiences

From a PDF or CAD design to a coordinated BIM model and, from that same model, to the 4D construction simulation, the web viewer, the renders and the film. One model for every deliverable.

  • BIM from PDF
  • 4D simulation
  • Web viewers
  • Renders
  • Virtual tours
  • Photorealistic video

What we do

One model. Six ways to explain the project.

We model once and reuse the same geometry to coordinate, plan and communicate. The method statement, the programme, the drawings and the video all describe exactly the same project.

01

BIM modelling from PDF or CAD

We rebuild architecture, structure, civil works and building services from plans, sections and details. CAD files are not needed to get started.

  • Dimensions and interfaces checked against the design
  • Classification, properties and georeferencing
  • IFC delivery at the agreed level of information
02

4D simulation and construction timelapse

We link the model to the construction programme to recreate the whole build: existing conditions, demolition, concurrent work fronts, erection, finishes and commissioning.

  • Elements linked to activities, dates and zones
  • Temporary works, site occupation and traffic phases
  • A film of the works from start to finish
03

Web-based 4D viewers

The project on its real terrain, explored phase by phase from any browser or phone. It is the format that accompanies our technical proposals.

  • Guided tour and synchronised mini Gantt chart
  • Hidden works shown in transparency
  • Nothing to install: it opens from a link
04

3D renders and infographics

Interior and exterior images to assess the project before it is built: materials, light, landscape and how the infrastructure fits into its surroundings.

  • Viewpoints and finishes agreed with the client
  • Phasing infographics for technical proposals
  • High resolution for presentation and print
05

Virtual tours and virtual reality

The project turned into a navigable space to walk through access routes, scale and operation. Our team includes real-time game designers.

  • 360° panoramas on the web
  • Interactive real-time application
  • Virtual reality headset experience
06

Photorealistic architectural film

A walkthrough of the completed infrastructure in operation, with a visual script, materials, lighting, cameras and people and vehicles in motion.

  • Agreed length, resolution and camera paths
  • For a technical proposal or for communication
  • Landscape and portrait formats

Animated infographics

Construction videos on real terrain

Built on the same model as the viewer: the construction campaign, plant and sequence, in under a minute.

Renders and walkthroughs

The project, before it is built

Renders of the completed works and 360° panoramas you can navigate in the browser. The renders in this section show a demonstration project.

Multidisciplinary coordination

BIM clash detection: conflicts resolved before construction

We coordinate architecture, structure and building services in a federated model. We check hard clashes and minimum clearances, group the relevant issues and track their resolution from one model version to the next.

  • Agreed rules. Versions, coordinates, discipline pairs, tolerances and exclusions.
  • Actionable issues. Views, element references, priority and owner for each clash.
  • Open workflow. Reports or BCF exchange; changes are validated by the design team.

A scope for every brief

From a phased sequence to the full experience

Not every tender or project needs the same thing. We size the work to what is at stake, the deadline and the level of demonstration you are after.

01 · ESSENTIAL

3D or 4D visual sequence

To explain phases, site occupation, plant and the progress of the works quickly.

  • Modelling of the key elements
  • Selected states or phases
  • Drawings and a short video
02 · ADVANCED

BIM model + 4D simulation

A BIM reconstruction linked to the programme to recreate the whole build and check the sequence zone by zone.

  • Coordinated BIM model
  • 4D construction planning
  • Web viewer with mini Gantt chart
03 · IMMERSIVE

Photorealistic experience

The most complete scope: 4D BIM, a georeferenced real-time viewer and a film of the infrastructure in service.

  • Real-time interactive experience
  • Free navigation and points of interest
  • High-quality final video

Workflow

A common base for BIM, 4D, the viewer and the video

Before modelling, we define the question each deliverable has to answer: a crane manoeuvre, two work fronts sharing space, a maintenance access or the final image of the project.

  1. Design in PDF or CAD

    We extract geometry, dimensions, quantities and constraints, even when no CAD files exist.

  2. BIM model

    We rebuild and georeference the required elements with a consistent classification.

  3. 4D construction

    We link the model to the construction programme to recreate the whole build.

  4. Final experience

    Drawings, web viewer, renders, walkthrough or film: whichever combination is commissioned.

Frequently asked questions

What you need and what you can commission

Technical guide: how we build a 4D BIM model for a tender starting from the design in PDF (Spanish).

Do I need CAD drawings or an existing BIM model?

No. We can start from the design in PDF. If the drawings contain vector data, we recover the geometry and check it against dimensions, quantities, mapping and the rest of the project documentation.

Does 4D BIM replace the construction programme?

No. The programme defines activities, dependencies and dates; 4D BIM links them to the model elements so you can see how each zone is built and check that the sequence holds together.

Does every project need a full 4D simulation and a viewer?

No. We deliver anything from an essential sequence to a complete immersive experience, and recommend a scope based on the intended use, the available documentation, the deadline and the budget.

Can the video show the infrastructure completed and in operation?

Yes. We recreate a walkthrough of the finished works with operation, traffic, users, lighting and the viewpoints agreed with you.

In what formats is the work delivered?

The model in IFC or another agreed format, images in high resolution, videos as landscape or portrait MP4, and viewers as a web link that opens in any browser.

Your next project

From the documents to the model you need

Share the design in PDF, CAD or BIM and tell us what you will use it for. For public tenders in Spain, the contract notice, link or tender documents are enough.
