Developing Coverage Analysis for IFC Files

November 16, 2010
Author(s)
Robert R. Lipman
Conformance and interoperability testing of product data exchange interfaces is essential to delivering reliable software implementations and meeting user’s expectations for interoperability between BIM software. For either type of testing, product data

Test Suite for Building Energy Analysis of Conceptual Spatial Layout

May 11, 2010
Author(s)
Kenway K. Chen, Robert R. Lipman, Mark E. Palmer
This report documents a test suite for validation and conformance testing in support of the interoperability among building design and energy analysis applications. The objectives of this test suite are to: provide to software vendors test cases to

Interoperable Methodologies and Techniques in CAD

December 1, 2009
Author(s)
Semiha Kiziltas, Fernanda Leite, Burcu Akinci, Robert R. Lipman
It is estimated that the cost of inadequate interoperability in the U.S. capital facilities industry is approximately $15.8 billion per year. Lack of or inadequate interoperability results in data and transfer problems and duplication of business

Mobile 3D Visualization for Steel Structures

January 1, 2004
Author(s)
Robert R. Lipman
Until recently, visualization of 3D models required computational resources available only on desktop computers in office environments. With the advance of technology, it is now possible to visualize substantial 3D models on mobile handheld computers in

Immersive Virtual Reality for Steel Structures

September 1, 2003
Author(s)
Robert R. Lipman
This paper describes an immersive virtual reality system for steel structures. The system integrates standard models and formats for representing structural steel and three-dimensional graphic objects with a framework for device independent virtual

Visualization of Structural Steel Product Models

May 1, 2003
Author(s)
Robert R. Lipman, K A. Reed
A visual interface has been developed to provide a means for users to visualize the steel structure represented by a CIMsteel Integration Standards Release 2 (CIS2) file. Using a web-accessible translator, objects in a user's CIS2 file are mapped to

Mobile 3D Visualization for Construction

September 1, 2002
Author(s)
Robert R. Lipman
Until recently, visualization of 3D models required computational resources available only on desktop computers in office environments. With the advance of technology, it is now possible to visualize substantial 3D models on mobile handheld computers in

Laser Scanning for Construction Metrology

March 1, 2001
Author(s)
Geraldine S. Cheok, William C. Stone, Robert R. Lipman, Christoph J. Witzgall, Javier Bernal
This paper summarizes work at the National Institute of Standards and Technology (NIST) in the Non-Intrusive Scanning Technologies for Construction Assessment Project. It will briefly describe the initial proof-of-concept phase of this project, the

Field Demonstration of Laser Scanning for Excavation Measurement

October 1, 2000
Author(s)
Geraldine S. Cheok, Robert R. Lipman, Christoph J. Witzgall, Javier Bernal, William C. Stone
The use of a scanning laser to measure terrain changes due to excavation at a construction site is described. The objective at this phase of the project is to develop the tools necessary to measure terrain changes in real-time. This paper focuses on

Automated Earthmoving Status Determination

February 28, 2000
Author(s)
William C. Stone, Geraldine S. Cheok, Robert R. Lipman
Efforts are underway at the National Institute of Standards and Technology (NIST) to develop automated non-intrusive production measurement systems and procedures for monitoring the status of general earthmoving operations at typical construction sites

Using VRML in Construction Industry Applications

February 1, 2000
Author(s)
Robert R. Lipman, K A. Reed
This paper describes initial research using the Virtual Reality Modeling Language (VRML97) in construction industry applications. The modeling of steel structures and construction equipment as objects for inclusion in construction-site world models was

Ladars for Construction Assessment and Update

January 1, 2000
Author(s)
Geraldine S. Cheok, William C. Stone, Robert R. Lipman, Christoph J. Witzgall
Work at the National Institute of Standards and Technology (NIST) on laser radar imaging of a construction site is described. The objective of the NIST research is to make measurements required in a construction project quicker and cheaper than current
