Building Environment Division

Computer Integrated Building Processes Group

Overview

The Computer Integrated Building Processes Group (CIBP) at NIST promotes advancements in the capabilities of the U.S. building industry by developing measurement science, methods, protocols and testbeds related to information, communication, sensing and automation technologies and improved work processes. Research topics include: building information modeling and interoperability; construction productivity; product data standards and project data standards such as IFC and CIS/2; intelligent and automated construction job site; integrated and automated project delivery; semantic modeling, validation testing and conformance testing. The group works with industry and the research community to apply research results to improving the design, construction and operation of the built environment.

Project Information

Some of the projects are part of the CONSIAT: Construction Integration and Automation Technology program which is part of the strategic priority area Measurement Science for Advancing Infrastructure Delivery.

The other BFRL groups that participate in CONSIAT are the Construction Metrology and Automation Group and the Office of Applied Economics. The other projects from those groups that are part of CONSIAT are:

[Click for larger image] The FIATECH project, Automating Equipment Information Exchanges (AEX) focuses on providing a standard way to exchange data, so that it is available for reuse over the lifecycle of a facility by different stakeholders and varied software packages. To accomplish this the project is developing XML specifications to automate information exchange among various software systems that support capital facility equipment engineering, procurement, construction, and operations and maintenance (EPCOM) work processes. These XML specifications standardize the names of equipment types and their attributes such as those found on common industry equipment data sheets. Industry software owners will be able to use the AEX project results to construct industry-standard software automation interfaces at reasonable cost using readily available, low-cost XML software development tools. Automated data interfaces between software systems will enable significant reductions in manual transcription costs and the occasional, but costly transcription errors. The economic benefits for industry deployment of these XML specifications are estimated to be substantial.
[Click for larger image] The General Buildings Information Handover Guide and the Capital Facilities Information Handover Guide define methodologies for defining the information requirements for the full facility life cycle to develop and implement an information handover plan for a specific general building or capital facility project. This is accomplished by: (1) establishing an overall facility life cycle information strategy, (2) determine the business requirements for information to be handed over at each life cycle stage, (3) develop a handover plan, and (4) implement the handover. IT developments for the ways in which faciliy information can be specified and managed means that the handover of information can be greatly improved, particularly in relation to its reusability and its quality assurance.
[Click for details] The CIMsteel Integration Standards (CIS/2) is the product model and data exchange format for structural steel project information. CIS/2 has been implemented by many steel design, analysis, engineering, fabrication, and construction software packages to create a seamless and integrated flow of information among all parties of the steel supply chain involved in the construction of steel framed structures.

NIST has helped software vendors implement the standard; helped steel designers, detailers, and fabricators use the standard; and has contributed to the future directions of the standard. The SteelVis - CIS/2 to VRML Translator has been developed to help software developers verify their CIS/2 file export and to help end-users in their work process.

[Click for details] The Industry Foundation Classes (IFC) are the product data model developed by buildingSMART to facilitate interoperability in the building industry. NIST has developed SteelVis - CIS/2 to IFC Translator to assist software developers in implementing IFC entities related to structural steel and to help end-users move CIS/2 information into IFC importing applications.

The group is also involved with the ATC-75 project for the Development of Industry Foundation Classes (IFCs) for Structural Components and the AECOO-1 project to develop an IDM and MVD for Building Performance Energy Analysis and Quantity Takeoff in early design.

Visualization Research

The Virtual Reality Modeling Language (VRML) is used for the visual representation and simulation of construction and building related models, activities, and processes. Most of the visualization research was completed by 2002 except for the work related to structural steel. A VRML plugin detector has been developed to check if your web browser is properly configured to be able to view VRML models.

If you're interested in your own local copy of most of the VRML models below, then download this free zip file to your computer. Unzipping the file will create a directory nist_cic_vrml. Use a web browser to load the file index.html in that directory to find the VRML models.
