BIM data structure: a complete guide to data structuring tools in BIM models

Discover all about software for structuring data in BIM models. From optimizing project management to creating specific BIM guides, explore how these tools are revolutionizing the construction industry

The use of Building Information Modeling (BIM) models is becoming increasingly common within the construction industry. But what are software for structuring data within these models? Let’s find out in this article, examining how these tools contribute to improving project management and the quality of BIM models.

Introduction to BIM software

BIM software is designed to help architects, engineers, and builders create detailed 3D digital models of buildings and infrastructure. These models are not just visual representations but also contain essential information about project components such as materials, costs, and scheduling. But what happens when it comes to organizing and structuring this complex data?

Data Structuring Tools (BIM data structure)

1. EIR Definition

One fundamental aspect in managing a BIM project is defining the EIR. This document specifies what information the client wants to obtain from a BIM project. Data structuring tools play a crucial role in this phase, allowing precise definition of which data should be included in the model. To delve deeper into the topic, we recommend you reading the article “Exchange Information Requirements: what is an EIR in BIM?

2. Creating Specific BIM Guides

BIM guides are documents providing detailed guidelines on how to create and manage a BIM model. Data structuring tools enable the creation of specific guides for each project. These guides define how to organize data within the model, ensuring consistency and compliance with industry standards.

3. Model Verification

A fundamental step in managing BIM projects is model verification to ensure accuracy and compliance with required standards. Data structuring tools support this phase, allowing the creation of customized verification rules for BIM control software. This significantly contributes to enhancing model quality.

4. Practical Example: usBIM.editor, usBIM.IDS, usBIM.bSDD, and usBIM.checker by ACCA software

To better understand how data structuring tools work, let’s take usBIM as an example, a web application developed by ACCA software. This tool offers a wide range of functionalities, including:

usBIM.editor

usBIM.editor is a software dedicated to editing, modifying, and enriching BIM models in IFC format. As part of the usBIM ecosystem, usBIM.editor offers a wide range of tools for managing and collaborating on BIM projects, allowing you to:

  • Edit and enrich BIM models in IFC format (see how in the article “IFC editor: editing an IFC model created with BIM authoring software“).
  • Edit geometric and informative properties of model entities.
  • Create project documentation, tables, and reports automatically from the IFC file.
  • Enhance the graphical presentation of the model with photorealistic renders and advanced architectural visualization tools.
  • Collaborate in real-time with the team on the model and share it via the usBIM cloud.

To discover all the advantages of usBIM.editor and get an overview of its main features, check the video below:

usBIM.IDS

usBIM.IDS is a tool that facilitates the definition of Exchange Information Requirements (IDS) to manage information exchanges in a BIM context. IDS are used to establish what information is needed, how it should be exchanged, and when it should occur in a BIM contract. In short, usBIM.IDS allows you to:

  • Detail which information is necessary for the BIM project.
  • Create a standard IDS file based on these specifications.
  • Improve information exchange workflows among project stakeholders.
  • Validate IFC files delivered by the modeler against the requirements specified in the IDS file.
  • Report non-conformities and generate detailed analysis reports.

With usBIM.IDS, designers and clients can leverage the advantages of the IDS standard to manage faster exchange flows and reduce errors caused by poor communication. Learn more in this video:

Furthermore, if you want to delve deeper into the topic, we recommend these blog posts: “What information can be managed with the IDS standard” and “Understanding the difference between the IDS standard and IFC or MVD“.

usBIM.bSDD

The buildingSMART Data Dictionary (bSDD) is an international library that enables various parties involved in the construction industry (designers, clients, owners, operators, manufacturers, and product suppliers) to exchange and share construction-related data. This library aims to overcome linguistic and disciplinary barriers, ensuring that concepts and terms used in the building industry have standardized international correspondence.

usBIM.bSDD is an application integrated into usBIM that simplifies BIM data management, ensuring compliance with international standards and enabling better standardization and sharing of information in the construction field. Among its main features:

  • Creating dictionaries allows users to create new object dictionaries in .bSDD format with guided data input.
  • Editing classifications and properties enables modification and enrichment of element classifications and properties in BIM models in IFC format.
  • Automatic validation provides an automatic validation system to ensure no errors in classifications and properties.
  • Association of classifications and properties allows users to associate specific classifications with dictionary properties, ensuring consistency and standardization.
  • Online upload allows uploading modified classifications and properties to the online service of buildingSMART International for future use.

Here are some useful resources to delve into the topic and understand how you can enrich and complete your IFC BIM models with the dictionaries and classifications of the buildingSMART Data Dictionary: an article to discover how the bSDD platform improves the design and construction process. A first video presents the main features of usBIM.bSDD; a second video example of using usBIM.bSDD in the digital survey of the conservation status of a historic building.

usBIM.checker

usBIM.checker is an essential tool for BIM professionals (BIM specialists, BIM coordinators, and BIM managers) who want to ensure the quality and compliance of data in their IFC models, meeting design specifications and tender requirements, enabling control and validation of data in IFC format models in the context of the BIM process. The main features of usBIM.checker include:

  • Verification of existence and control of object property values within the IFC model.
  • Verification of data correctness assigned to properties against predefined values, ensuring they meet project specifications or required standards.
  • BIM validation checklist: generation of control checklists with data that the IFC model must have, helping ensure the model meets certain requirements.
  • IFC Editing: enables inserting, editing, and deleting properties within an IFC model, simplifying data management operations.
  • Import and export from Excel files.
  • Generation of validation reports comparing data from the IFC file with defined checklists, identifying any inconsistencies.
  • Federation and integration of data from different BIM Authoring software and BIM tools into a single IFC file, enabling more efficient data management.
  • Quality control and BIM Validation-Checklist.
  • Basic and advanced functions for visualization and editing of the IFC model.

In the video below, you can see how to check and validate all the data of an IFC format model at each stage of the BIM process thanks to usBIM.checker.

Conclusions

Data structuring tools are essential elements for effective management of BIM projects. They enable the creation of personalized guides, precise definition of client requirements, and improvement of the quality of BIM models. With the continuous evolution of BIM technology, these tools will continue to play a fundamental role in the construction industry, contributing to more efficient and high-quality projects.
