Design Authoring Process

BIM dictionary defines the design authoring as “A Model Use representing the process of developing Generative Models or Parametric Models for design exploration, design communication and design iteration purposes. Design authoring is a key BIM activity leading to model-based 2D Documentation, 3D Detailing and other model-based deliverables.”

Description:

A process in which 3D software is used to develop a Building Information Model based on criteria that is important to the translation of the building’s design. Two groups of applications are at the core of BIM-based design process are design authoring tools and audit and analysis tools. Authoring tools create models while audit and analysis tools study or add to the richness of information in a model. Most audit and analysis tools can be used for Design Review and Engineering Analysis BIM Uses. Design authoring tools are the first step towards BIM and the key is connecting the 3D model with a powerful database of properties, quantities, means and methods, costs and schedules.

Process Overview:

Design authoring starts with identification of various models and their contents required by different disciplines as shown in the first two processes in the map. Next process is the development of an initial model by the architect for reference of all disciplines. Based on this, the disciplines can prepare their schematic models which will be reviewed in a workshop by all the stakeholders. The review will be resulted in acceptance or rework of the schematic models. On acceptance, the same models will be expanded to design development models by corresponding teams and another workshop for review will be carried out. On successful review, the models passes through the detailed documentation phase and final review will be carried out.

OpenBIM Design Process Workflow

This table describes the design process workflow within openBIM. This FMT used design authoring process from schematic design, to design development to construction documentation, and uses an openBIM workflow to allow interoperability and validation throughout the entire process.

Stage Process Description

1 Authoring Software (Schematic Design)

2 Interoperability Software (federation/ revision)

3 Authoring Software (design development)

Using desktop software, including Revit and ArchiCAD, the appointed party develops generative and parametric models in native file formats. Discipline managers are to refer to the Sprint Planning board to manage tasks within timelines and check models in accordance with ‘definition of ready’ and ‘definition of done’ specifications. In accordance with MVD specifications, the disciplines export required data for BIM uses in IFC format.

Using interoperability software, which includes BIMcollabZOOM, each discipline validates the IFC models against the federated model to review for possible data loss, data corruption, and incompatibility with defined specifications. The issue management information is exported as BFC to be corrected in authoring software (if necessary), before final models used in Design Development authoring, and uploaded to CDE platform.

5 Authoring Software (construction documentation)

6 Interoperability Software (federation/ revision)

7 Cloud Software

Using interoperability software, which includes BIMcollabZOOM, each discipline validates the IFC models against the federated model to review for possible data loss, data corruption, and incompatibility with defined specifications. The issue management information is exported as BFC to be corrected in authoring software (if necessary), before final models used in Construction Documentation authoring, and uploaded to CDE platform.

Using desktop software, including Tekla, Revit and ArchiCAD, the appointed party develops detailed generative and parametric models in native file formats and prepares construction documentation for project handover. Discipline managers are to refer to the Sprint Planning board to manage tasks within timelines and check models in accordance with ‘definition of ready’ and ‘definition of done’ specifications. In accordance with MVD specifications, the disciplines export required data for BIM uses in IFC format.

Using interoperability software, which includes BIMcollabZOOM, each discipline validates the IFC models against the federated model to review for possible data loss, data corruption, and incompatibility with defined specifications. The issue management information is exported as BFC to be corrected in authoring software (if necessary), before final models uploading to CDE.

Using cloud software, which includes BIMSync, all disciplines upload IFC/BFC files to the CDE to create a federated model. The appointed party can run clash detection against all models and data in the federated model by deploying plug-in Solibri. Before BCF data is returned to authoring platforms for correction, team members and stakeholders can make cooperative decisions on improvements.
