real BIM projects...yes they exist

Reblogged from Life, BIM and nuclear science in Southern Africa:

I have been in discussion recently with the organisers of a BIM summit in Johannesburg, planned for August 2012. I must admit, I am looking forward to IT, should be an interesting experience.

As the discussions developed, I realised our local BIM needs two things desperately:

  1. confidence, yes, confidence, many people in SADC use a BIM software within their own discipline, however project wide is a very different level of treachery, which most design consultants and contractors are not willing to enter into…

Open BIM FAQ: What are the characteristics of the “traditional” approach?

. Opinion/Review . , , , , , , , , , , , ,

Traditional approach to interdisciplinary collaboration basically means any form of 2D collaboration including paper, DWG or PDF or any other 2D forms. This approach can be characterized as follows:

  • Limited coordination workflow → the whole workflow relies too much upon manual work and willingness of cooperation between the parties
  • Heavy conversion of data → the whole workflow is based upon “dumb” intermediary formats so data conversion results serious information loss
  • No utilization of others’ data → due to differences in documentation conventions the received 2D data cannot practically be further utilized
  • No comprehensive coordination → due to the 2D nature of the workflow the project cannot be coordinated in one integrated environment

Open BIM FAQ: What are various approaches to address collaboration issues?

. Opinion/Review . , , , , , , , , , , ,

Sticking to the technical level coordination between the different trades has been through a long evolution. Traditionally different trades submitted full printed documentation sets at the different stages of the design process and used light-tables to try and coordinate the different building structures and building systems. This approach is still popular today with paper’s digital equivalents the still 2D DWG and PDF based collaboration workflows.

with the much richer building information model data. With BIM models there has been an increasing demand for true model based collaboration. Two fundamentally different approaches emerged one known as the “platform” approach where collaboration happens using the different branches of the same software solution, the other known as the “open” approach where different software solutions form the basis of model-based collaboration.

Open BIM FAQ: What are AEC projects’ key collaboration issues?

. Opinion/Review . , , , , , , , , ,

Even at the smallest scale – AEC projects are endeavors charged with serious collaboration challenges. Successfully completed building projects are the result of the collaboration of different teams of building professionals such as architects, different types of engineers and a network of the general contractor and subcontractors. These teams more often than not have divergent “trade” priorities and belong to independent organizations with counter-pointing interests.

Due to the above these are collaboration issues present in most AEC projects:

  • Lack of real coordination workflow → parties in effect don’t coordinate their work only share documentation in progress to show design intent
  • Lost information during data conversion → native data needs to be converted to open in the other parties’ environment for coordination
  • Interpretation issues of data from other party → data only becomes real information when there is an established workflow for interpretation
  • Limited utilization of building data created by others → design information created by one trade cannot be integrated into other trades’ environment
  • Missing follow-up of design changes between the trades → coordination is not a one-time data exchange but a continuous bidirectional process
  • Lack of overall coordination environment for multiple trades → coordination ideally includes all related activities such as collision detection, quantity takeoffs and constructability issues
  • Lack of detailed model for construction → late coordination and spent time to produce 2D drawings forces construction to be done on sketches/not-up to date plans

Open BIM Program

. AddOn, News . , , , , , , , , , , , , , ,

Open BIM collaboration has been a mission critical strategy for GRAPHISOFT and many AEC companies in the past years. GRAPHISOFT® together with buildingSMART® International, Tekla® and several leading software vendors joined forces to launch a global program to help promote Open BIM collaboration workflows throughout the AEC industry. GRAPHISOFT has been one of the primary driving forces in the formulation of this program and we are hoping to have initiated a true global industry movement where the “open” approach to interdisciplinary collaboration will ultimately prevail.

The global launch on 13 March by the 10 companies joining in the first round will be the “kick-off” for the program that will provide the framework for ongoing global and local Open BIM activities. One of the upcoming global activities is the Open BIM Live Online Seminar on 27 March featuring Rift Architects that has applied the Open BIM collaboration workflow to design and build a high-end residential complex in the heart of the Oslo fjord in Norway.

 In SADC, we are supporting the move to OPEN BIM, with a series of regional events in March and April 2012, follow this link to register for an event near you. Further, keep an eye on this article for FAQ updates on OPEN BIM and details of local SADC projects and consultants utilising the technology.

Open BIM Program for Improved AEC Collaboration 

March 13, 2012 — buildingSMART® International, GRAPHISOFT®, Tekla® and several leading software vendors joined forces to launch a global program to help promote Open BIM collaboration workflows throughout the AEC industry.  

Open BIM is a universal approach to the collaborative design, realization and operation of buildings based on open standards and workflows. Open BIM is an initiative of buildingSMART and several leading software vendors using the open buildingSMART Data Model. 

The Open BIM approach offers key benefits to the stakeholders of building projects:

  • Workflow integration results in greatly reduced coordination errors compared to sheer file exchange-based coordination of the different disciplines.
  • Project members can work with the best-of-breed solutions in their respective fields without risking “incompatibility” hence exclusion from certain BIM projects.
  • Project members can maintain full control over software upgrades independently from their peers on the different AEC projects they participate in.
  • Accessibility of BIM data is provided for the entire lifecycle of buildings including design, construction and operation.

The Open BIM program’s aim is to help coordinate efforts related to the promotion and implementation of Open BIM collaboration workflows by providing common definitions, requirements and branding. AEC software vendors, AEC practices (designers, engineers, contractors) as well as AEC projects are all welcome to participate and use the OPEN BIM logo as a guarantee for successful and streamlined collaboration.

Companies participating in the Open BIM program from day #1 include buildingSMART International, GRAPHISOFT, Tekla, Nemetschek AG, Trimble, Nemetschek Allplan, Nemetschek Vectorworks, Inc., Nemetschek SCIA, Data Design System and Solibri. For more information, please visit: www.openbim.com, or join the OPEN BIM webinar organized by GRAPHISOFT, Tekla, and Data Design System on March 27.

The Stadium rendered on C4D

Client: Durban Strategic Projects

Lead Architect: Theunissen Jankowitz

The Moses Mabhida Stadium in Durban, South Africa, forms a part of the South Africa Fifa 2010 World Cup facilities.

This model was created in ArchiCAD for client coordination purposes. All project details were fully modeled, including doors and windows as per schedule and balustrading, roof edge, cat walk and other detailing. This work was kept up to date to construction detailing level throughout.

The project was assembled with a combination of hotlinked modules and teamwork in terms of the ArchiCAD 3D model and was supported by Xref for 2D CAD consultant data updates. This process of live data links and updates was essential to maintain model accuracy during the frenetic detailing update cycle of the “fast track” construction process.

A live link was also maintained with the Cinema4D rendering file, which again required constant updates for client interrogation.

Several 3D output formats were sourced from the 3D model for use by a broad spectrum of associated project consultants.
