BIM is possibly the main evolutionary change faced by the construction industry over the next years.

It is a working method that changes the way of designing, building and operating buildings and infrastructures around the world. Its aim is to digitise all of the project information in an accessible and collaborative manner.

BIM is nothing other than a virtual prototype with which to detect and refine the design, plan the operations or control project costs. ACCIONA has a corporate implementation plan that deals with training, methodology and technology.

The greatest benefit of the application of BIM in a project is for our Clients. In short, BIM helps avoid incoherence and errors, save time and reduce costs by making it possible to bring our Clients’ vision to life before the execution phase.

Furthermore, after finishing construction on the BIM model, it becomes an effective tool for the management and operation of the infrastructure. By phases, these advantages are summarised as follows:


  • Gain a better understanding of the project.
  •  Facilitate the marketing of the finished project.
  •  Optimise cost estimations.
  • Guarantee coherence of data.


  • Anticipate any possible challenges and difficulties before execution,
  •  Increase reliability of costs and term of execution.
  •  Improve organisation and safety on site


  • Optimise maintenance and management of infrastructure.
  • Anticipate and simulate the evolution of buildings.
  • Manage new and existing buildings more efficiently.


ACCIONA simulates the real construction from the first stages of the project to study alternatives for construction processes, coordination of disciplines, and detecting ambiguities, problems or risks that can be resolved much before the design is executed.

Carrying out the necessary modifications in phases where the cost impact is lower entails greater savings for the project. In brief, the benefit of creating a ‘virtual site’ is to ensure that the procedures to be carried out are the optimal procedures for ensuring the project’s viability.


Traditional organisation and time management tools in a construction project make it possible to represent the technical team’s ideas and projections in a document.

Every element of the BIM model is linked to the works schedule, which enables an exhaustive control process of the phases, adjusting times according to the model. Likewise, it makes it possible to automatically view the progress of the works carried out.

The link of this planning to BIM also makes it possible to verify and ensure that this planning is realistic. This is possible because said planning is restricted to the real limitations of the works.


The application of BIM implies a substantial change in the current work methods and an improvement in the communication between the agents involved in the project.

All of the site agents involved work on a single updated and more visual model, which makes it possible to have greater communication between agents and a better understanding of the project at all levels.

Incorporated into ACCIONA’s processes, it avoids any inefficiency caused by information that has not been updated, and increases productivity by updating the changes carried out to the project in all of the existing documents.


The final aim of the model is to offer the client an as-built BIM model with all of the relevant information for infrastructure management and maintenance.

Initially, an agreement is reached with the owner regarding the relevant information to be included in the as-built model. During the design and construction phases, ACCIONA ensures that these modelling needs are complied with to obtain the as-built model required by the client.
