The Architectural/Engineering/Construction (AEC) industry is slowly shifting toward performance-driven project and project delivery. Assuring good performance requires efficient performance control processes. Among the different construction performance control processes, many critical ones, including progress tracking, productivity tracking and dimensional quality control, rely on efficient th...

a r t i c l e i n f o Keywords: BIM BIM-server Multidisciplinary collaboration Operational technical requirements Support technical requirements Most complex projects in the Architecture, Engineering, and Construction (AEC) industries involve multidisciplinary collaboration and the exchange of large building data set. Traditionally, the collaboration efforts across the disciplines have been bas...

The Internet is becoming more and more useful in the field of architectural design that what we conventionally called CAD might soon be changed to iAD (internet aided design) (Zhou and Krawczyk 2000). In order to have a clear vision of what iAD will be or should be, we should examine what is the current situation. This research focuses on an investigation of selected web vendors, which are typi...

This paper presents a new 3D scene analysis system that automatically reconstructs the 3D geometric model of realworld scenes from multiple range images acquired by a Laser Range Finder on board of a mobile robot. The reconstruction is achieved through an integrated procedure including range data acquisition, geometrical feature extraction, registration and integration of multiple views. Differ...

Low-power wireless system design requires optimization at all levels of the design abstraction. Sub-1V operation is the key to lowpower design and requires modification of the process technology (e.g., multiple threshold devices, variable threshold devices using bulk biasing or dual-gate SO1 technology, etc.), circuit optimization, and architecture optimization. The CAD tool requirements for th...

The paper outlines the relevance of computational geometry within the design and production process of architecture. Based on two case studies, the digital chain from the initial formfinding to the final realization of spatial concepts is discussed in relation to geometric principles. The association with the fascinating complexity that can be found in nature and its underlying geometry was the...

The creation of three-dimensional models of existing architectural scenes with the aid of the computer has been commonplace for some time, and the resulting models have been both entertaining virtual environments as well as valuable visualization tools. Large-scale efforts have pushed the campuses of Iowa State University, California State University – Chico, and swaths of downtown Los Angeles ...

It is true that the commercial applications used in architectural offices have mainly focused on CAD as a drafting tool, although the primary functions of computers in architecture have been changed from the computer-aided drafting to its 2D or 3D graphic representation and in recent years to the collaborative design among different specialists, such as architects, engineers, construction manag...
