ICDAS Founder 


ICDAS is an abbreviation of Integrated Construction Design, Analysis and Animation System.

This is state-of-the-art add-ins software that automatically, and concurrently, creates BIM

and FEM models from a common parametric input in Excel, *.xml file or normal text file.

ICDAS addins/plugins do not provide only a parametric interface for BIM and FEM models,

but also to automate the models, in building and infrastructural constructions, as well.


BIM and FEM models have been a wish for construction industry in many years. Software for BIM and FEM are developed fast, very fast, but still in two different products in the last era of Industry 3.0. Recently, Structural Analysis for Revit and Tekla Structural Designer has presented theirs BIM-FEM integration with promising technology in the Industry 4.0. Yet, the FEM features so far are limited in building construction with a few functions. On the other hand, full FEM features are found in some leading FEM software, but they do not communicate clearly to the BIM model. As the result, designer/assistant and engineer work on two different inputs for the two platforms, and unfortunately, overlook the deviations. ICDAS eliminates these deviations by get the two software to read the same parametric input, and to automate the same models through ICDAS add-ins/plug-ins. In doing do, ICDAS has since 2008 tested on many BIM and FEM tools to select the default. Among many opportunities, Revit (Revise Instantly) and LUSAS (London University Stress Analysis System) have been chosen as default tools in ICDAS workflow. Revit provides intelligent model-based technology, and in 2016 introduce one click to Revit LIVE cloud service and one next click to Virtual Reality for immersive visualization (HTC headset needed). LUSAS provides full FEM features for building and infrastructural constructions.

in an ICDAS project can both be a building or an infrastructural constructions. The materials are in concrete and/or steel. For building construction the materials are stored in Revit Material Libraries as glass, wood, insulation… and so on. For infrastructural constructions e.g. bridges and wind turbine foundation Revit family generic models are employed to automate any shapes of the profiles, and curved alignments for bridges. Construction can also be a quite simple as you meet often in your projects. Some examples are shown in the Models tab above. The term “Construction” in ICDAS from 2017 March refers also to ‘Virtual Design & Construction (VDC)’. It is about data management of 3D information model from phase to phase through a construction processes. VDC is also known as designing and then building virtually before building in reality, using digital tools such as wearable HoloLens and Headsets for Augmented Reality (AR) and Virtual Reality (VR). More about these technologies are outlined in the design section. 



in ICDAS happen by automating BIM and FEM model on the same time, or just the needed BIM or FEM model solely. The automation read a common parametric Excel input, and then automates a Revit model and a LUSAS model immediately. Unlike BIM-FEM or FEM-BIM integration, the users do not need to complete the one task for the other task. In case of constructions having standard steel profiles, ICDAS automation reduces further time to input profiles twice in BIM and FEM software as they are inputted once in Excel file. Advantages with ICDAS Excel input are further:



› very large numbers of parametric objects can be automated in one click, as

  the Excel allow 1048576 rows and 16384 columns input of data.


› be also the input for other software employed in project if other

  automations desired.


› be also the output of data writing back from 3D information model.


two or many models can be in the same Excel file, as only the first two

  sheets are used to BIM and FEM. The users can easily modify numerical

  input and compare graphics from project to project.


› allow the users to apply the other sheets for other calculations, e.g. points

  of curved lines/surfaces which are linked to sheet1 for BIM model, or

  Eurocodes post processing for FEM results.


Design in ICDAS is in new level of graphical visualization, both of building and infrastructural constructions. The automated Revit model just send to Revit LIVE and Virtual Reality (VR) just by two clicks mentioned at ‘Integrated’. With HTC headset the users will experience VR in immersive visualization of the construction in ratio 1:1 and 360°. It helps the users to optimize geometrical input, take manual modifications to build the construction in virtual reality before it is built on site.



in ICDAS refers to two issues described in short below.


› In terms of structural analysis it refers to FEM software such as LUSAS, ROBOT or StruSoft. Analysis model provides e.g. deformations and sectional forces for a construction for a given load or loading combination. As the results all dimensions of components of the construction are optimized and verified for a given code, e.g. Eurocodes.


› In terms of VDC, the analysis refer to 4D- and 5D models for time- and price scheduling on each period during a project. Software such as Synchro (4D) and Sigma (5D) are used for these tasks. They provide in addition also quantity, project markup, conflict resolution, code checking, flow analysis, energy analysis or visualization. 4D- and 5D analyses apply Revit information model as input (or other BIM tools which export the model to IFC format).


For the structural analysis ICDAS focus on automation for the FEM model with:


   - Geometry of the model as BIM information model

   - FEM mesh, element properties, materials, coupling & support conditions.

   - Load cases & loading combinations on the model.


Once the above automations executing on screen, the users can start the analysis work. LUSAS will display deformations in 3D cross section, from version 16 also perspective view. Smart combinations of envelopes of load cases, and opposite, are the features that ICDAS choose LUSAS as default FEM tool. LUSAS is also easy to use for both of simple and advanced constructions.


For VDC 4D and 5D analysis for bridges the users can self-develop the time- and price sheets in the existing Excel file. There are not many elements in bridges than in buildings where wall, door, window, floor, roof is varying by level. For concrete bridges ICDAS has already taken the reinforcement quantity modelled in Revit down to Excel file automatically.



 in an ICDAS project refers to two issues described in short below.


› Animation of landscape, terrain and 3D information model using 3ds Max,

  AutoCAD Civil 3D and Revit, respectively.


› Animation of 3D model in line with time scheduling and price as the

  construction is built in time function, using Synchro and Sigma, respectively.


For the landscape animation ICDAS provide guides for rendering’s parameters and animating camera motion in 3ds Max, and how to edit the move in highest quality of images.





 in an ICDAS project refers to the following points as summary for the above mentioning concepts

› BIM-FEM integration

› AR and VR reality tools

› Design and Static Documentation


The two available workflows for BIM-FEM in ICDAS are

› Automate Revit (BIM) and LUSAS (FEM) models concurrently.

› Automate FEM model from existing BIM model, or opposite.


Depended on type of construction, and available materials of a project from the beginning, one can select a suitable workflow of BIM-FEM integration. The first workflow is suitable for constructions which require advanced structural analysis features with LUSAS, and where both of BIM and FEM are created concurrently from the beginning. This option is powerful for companies which can design and analyst within the company. The second workflow is suitable for the cases where one of the models is existed, either a BIM model or a FEM model. This option requires high level of skill from the users in both of BIM and FEM to ensure the export/import is correct. ICDAS provide guides and add-ins for individual cases of this option. The add-ins can e.g. be automatic creation of loads and loads combinations on the FEM model which are not created in the BIM model.


In both of workflows ICDAS focuses on digital tools for digital construction. With e.g. AR and VR tools (HoloLens and Headsets) the users can easily check any detail in the 3D construction in scale 1:1. The papers drawings for 2D dimensions are always available from the BIM model, which can be automated at any desired section.


Finally, System in ICDAS focusses also on Design and Static Documentation which are generated from FEM and BIM tools. 



 is a small team of structural engineers and .NET C# programmers with over
17 years' experience in our fields. Yet, our technology has been used in Ring

3 Light Rail project, Copenhagen, Denmark to control the 3D geometry and

to perform a part of the FEM analyses. The Ring 3 is the biggest light rail project

in Denmark, as well as in all the five Nordic countries (2016-2021). In April 2018

ICDAS work directly for the Danish Road Directorate. We recreate the existing

constructions from thousand of existing drawings to one BIM model and to

perform the FEM analyses for the maintenance servicing.
