BIM, building information modeling, is nudging aside blueprints in the industry.

David Goll
Reporter - Silicon Valley / San Jose Business Journal
BIM is brimming with potential. Computer software that allows architectural firms and construction companies to engage in virtual design and construction activities yields big reductions in costs and building schedules.

After spending $450,000 to jump into the BIM revolution several years ago, officials of Blach Construction Co. in Santa Clara realized there was a distinct shortage of prospective employees being trained in this specialty. Purdue University in Indiana and California State University, Chico were among a small handful of schools with BIM courses. So they approached former San Jose-Evergreen Community College District Superintendent Rosa Perez to see if she would agree to launch such classes in Silicon Valley.
"She thought it was a great idea and told her people to make it a priority," said Juan Barosso, Blach's vice president of pre-construction services.

Four years later, it's a reality. A three-semester BIM course of study started Sept. 6 at Evergreen Valley College in San Jose, enrolling 27 students working on certificates. According to Barosso, plans are already afoot to make the course a full two-year program that will award an Associate of Arts degree.

S$6m BIM fund benefits more than 100 local firms
04:45 AM Nov 10, 2011

SINGAPORE - More than 100 local firms, including about 30 engineering consultants, have received support through a S$6 million fund set up to promote building information modelling (BIM) in the construction industry. Speaking at the Professionals Engineers Board Day of Dedication yesterday, Minister of State for Trade and Industry and National Development Lee Yi Shyan revealed that S$4.2 million, or about 70 per cent, of the fund has been committed.The BIM fund is part of a larger S$250 million Construction Productivity and Capability Fund and was set up by the Government to ease the transition from two-dimensional computer-aided design to three-dimensional modelling technology. The BIM fund covers costs on training, consultancy, software and hardware.Referring to the Addendum to the President's Address last month in Parliament, Mr Lee reiterated that the Ministry of National Development is committed to raising the capabilities and productivity of the construction industry. "Towards this goal, I see great potential for our engineers to play a transformational role in shaping the industry," he said.The Building and Construction Authority (BCA) aims to have BIM widely adopted across the industry by 2015. Mr Lee also said that for the next two years, the BCA projects high construction demand of between S$21 billion and S$28 billion a year, primarily due to the ramp up of the supply of Housing and Development Board flats and new development projects.

BIMtionary: Wall Function Trickery

BIMtionary: Wall Function Trickery:
...Apparently within the wall's type properties, if your wall is set to a "Foundation" function you can't use a level above as the "Top Constraint." ...

Same issue in 2012- THNX for the tip! it was driving me nuts!

FW: Bluebeam compare PDF documents

Bluebeam has a really nice feature to compare 2 pdf documents. Under the menu Document > Compare document, then select the PDFs to compare.

Bluebeam will highlight areas that have changed. It also scroll locks the view so as you pan and zoom – both views remain synchronized.

FW: BIM Buzz

Pretty good site for buzzwords- here are the ones I have run across the most:

Industry Foundation Classes, is a data exchange method that specifies elements that are used in building construction in an agreed manner that define a common language for construction.  IFCs provide a foundation for the exchange and sharing of information directly between software applications of a shared building project model. The IFC data model is a neutral and open specification that is not controlled by a single vendor or group of vendors. It is an object oriented file format to facilitate interoperability in the building industry, and is a commonly used format for BIM.  The format is known as ifcXML. ifcXML2x3 (current version) is currently supported by Autodesk, Graphisoft, Nemestchek and Bentley.


Construction-Operations Building Information Exchange is a standard way to manage information from a BIM model that is essential to support the operations, maintenance, and management of the facilities by the owner and/or property manager. The COBIE approach is to enter the data as it is created during design, construction, and commissioning.  Designers provide floor, space, and equipment layouts. Contractors provide make, model, and serial numbers of installed equipment.  Much of the data provided by contractors comes directly from product manufacturers who also participate in COBIE.

buildingSMART Alliance operates within the independent nonprofit National Institute of Building Sciences (NIBS). This public/private initiative expands on goals of the North American Chapter of the International Alliance for Interoperability (IAI-NA), whose Industry Foundation Classes (IFCs) have initiated open standards for national and international links among industry players. It provides developers and users of Building Information Models (BIMs), the digital tools that are increasingly helping to share highly accurate information throughout a facility's life cycle.

Integrated Project Delivery, a new project workflow method and supporting contracts developed by the AIA and ConsensusDocs, which leverages early contributions of knowledge and expertise through the utilization of new technologies, allowing all team members to better realize their highest potentials while expanding the value they provide throughout the project life cycle.  IPD avoids the realization phase challenges by allowing project data to be analyzed and understood prior to construction.

National CAD Standard - a US government sponsored standard that coordinates the efforts of the entire industry by classifying electronic building design data consistently allowing streamlined communication for the industry.

National Institute of Building Sciences, a United States Government organization that serves as an interface between government and the private sector. The Institute's public interest mission is to serve the Nation by supporting advances in building science and technology to improve the built environment.  This organization leads the buildingSMART Alliance, National Building Information Model Standard (NBIMS) and National CAD Standard (NCS) programs.

National Building Information Modeling Standards, exists to provide a National BIM Standard to improve the performance of facilities over their full life-cycle by fostering common and open standards and an integrated life-cycle information model for the A/E/C & FM industry. The efforts of this program continue that of the FIC which was integrated into NBIMS in 2008.

OmniClass Construction Classification System, a new classification system for the construction industry.  OmniClass is useful for many applications, from organizing library materials, product literature, and project information, to providing a classification structure for electronic databases.  It incorporates other existing systems currently in use as the basis of many of its Tables "MasterFormat" for work results, UniFormat for elements, and EPIC (Electronic Product Information Cooperation) for structuring products.

UNIFORMAT - Uniform Classification System, is a system for organizing preliminary construction information into a standard order or sequence on the basis of functional elements. Functional elements often referred to as systems or assemblies, are major components common to most buildings that usually perform a given function regardless of the design specification, construction method, or materials used.  UniFormat users can easily understand and compare information since it is linked to a standardized elemental classification structure. The use of UniFormat can provide consistent comparable data across an entire building life cycle. The use of UniFormat's elemental framework reduces the time and cost of evaluating alternatives in the early design stages of a project, assuring faster and more accurate economic analysis of alternative design decisions.

WBDG - Whole Building Design Guide is an online gateway for up-to-date information on integrated Whole Building design techniques and technologies, providing news and informational resources such as the JBIM, Journal of Building Information Modeling.

XML - Extensible Markup Language is a general-purpose specification for creating custom markup languages for computer software.  It is classified as an extensible language because it allows the user to define the mark-up elements.  XML's purpose is to aid information systems in sharing structured data, to encode documents, and to serialize data.

gbXML - Green Building XML is an [xml] file format standard that allows one energy analysis program to 'talk to' or interoperate with another.

FW: Revit Tip- COPING in 3D - peaked brick example

To create the coping that sweeps in 3 dimensions we can use an in place family. (One of the few instances in place is useful)

Create a coping profile – load it into your project.

You can use the same in place family to create the coping for the entire building.

To start:
Create an in place family
Create a sweep
Set the work plane- use "pick work plane"
Sketch the path - Use the pick tool for the ridge
Add "tails" horizontally so we can join them up later (in image 3)
Finish the sketch
Select the coping profile for the profile.

Finish the first sweep.

The second sweep will be hosted to the "top" of the wall- reference planes to "host" the base sketch could be used as well…

Once the pieces have been created- Then the multiple planes can be "joined" under the modify tab- this will get rid of the seams- final product shown below:

I am still looking for a 3d sweep/sketch…

Question for those with projects spanning multiple versions of Revit... What strategy has been employed - (1) Upgrade to the latest (assuming all participants are willing/able) or (2) pick a version and stick with it for the duration of the project?

(Knock on wood… )
Revit really hasn't had significant issues with upgrading large projects in the past 3 releases(2009, 2010, 2011). I hope 2012 will be as painless.

For anyone planning to maintain a stake in the industry- Autodesk's subscription option is a no-brainer. And- If everyone is on subscription - then it is a limited issue to keep every project current to the latest release.

Some adopt 'wait till the first patch is released' – which seems be about half way through the release cycle these days; but personally- I would rather test and upgrade ASAP so the new features in the new releases can be leveraged.

Autodesk seems to have done a great deal more R&D as well as substantial beta development for Revit... So where this was an issue with stuff being broken before, they have been pretty good about not releasing junk that is broken or prone to blow up.

In 2009 and converting between previous versions I have seen sheets get mangled, some content in views drop out- like annotations, match lines disappear. And occasionally we have had the “Cannot delete non editable worksets” when purging after an upgrade, forcing manual purging.

One suggestion for upgrading- If you create a set full of plans, sections, elevation sheets and exported schedules- you can compare the PDFd sheets immediately after upgrading using tools like Bluebeam PDF Revue Document compare. It will highlight any changes in the sheet sets rather effectively.

Combine this with some key template content when starting projects and you have a well armored solution to utilize for upgrades…

FW: USACE-ISC 3D BIM Visualization | Autodesk Revit for CoS Projects | Bradley BIM

This looks promising...
If this is the case The USACE who currently requires Bentley BIM (a competitor of Autodesk) on Center Of Standardization projects - will include Revit as a platform in their 2012 BIM roadmap.
