Designing in Three Dimensions for Manufacturing Facilities
Du Pont Engineering is using Three-Dimensional Design for the design of our manufacturing facilities. Our 3D design system was used on several projects in 1992, and full implementation...
Object Oriented Modeling of Structural Systems
Computational engineering in structural design is no longer restricted to numerical approaches. Increasingly, also non-numerical, in particular, cognitive problems can be implemented into...
Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...
Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....
A Model to Quantify Work Space Availability for Space?Contrained Scheduling Within a CAD Environment
In any given process work area, a task or activity requires a specific amount of space for its execution. This required space must be accommodate by the physical space of the work area...
A CAD-Based Construction Simulation Tool Kit for Construction Planning
Current planning and scheduling techniques place considerable reliance on the planners judgement, imagination and intuition. The result of such techniques is typically lengthy text reports...
CAD Applications for Material Handling in the Construction Environment

Comprehensive Site Monitoring Through Model Based Reasoning
The authors of this paper have developed a computer object oriented intelligent construction site modeler which is dynamically linked to a 3D CAD system. Model Based Reasoning is used...
The Automation of Freeway Ramp Junctions Analysis
Congestion on urban freeways has been steadily increasing. In contrast, capacity expansion, by means of constructing new roadways, has not kept pace with the growth in demand. The primary...
Object Based Visualization of Physical Behavior
In engineering science, the physical behavior of solids, fluids, gases and multiphase systems is analyzed with computational models. Numerical methods form the basis of the computational...
An Object Oriented Approach to Computing with Structural Components
The structural analysis process can be modeled in two separate steps: definition of structural systems and analysis of a discrete numerical model; the transmission between these two models...
Computer-Aided Decision Model for Selecting a Contractual System
An owner of a construction project often faces the problem of selecting a contractual arrangement. The process of selecting a contractual system depends on the owner's preferred risk sharing...
A Work Packaging Process Model for Petrochemical Plant Piping Construction
This paper presents a model for the current work packaging process for petrochemical plant piping construction. The basic foundation of the model is formed by identifying major decision...
Linear Scheduling: A Practical Implementation
This paper describes the features and use of a family of planning structures that provides the basis for a superset of the traditional critical path method which includes linear scheduling....
ICPS: Integrated Construction Planning System by Object-Oriented Planning Models
Knowledge processing for integrated building system planning and construction system planning poses challenging problems to integrate design and construction process efficiently. While...
Floodplain Delineation Using TINS
Triangulated Irregular Networks (TINs) are becoming an increasingly common tool for modeling terrain surfaces on the computer. They are formed by the triangulation of scattered xyz data...
Application of Computer Simulation in the Research of Rail Structure Vibration Reduction
The wheel/rail system is described here as a random vibration system, and the state variables are expressed with quadratic evaluation function. The passive control problem of the random...
Interdisciplinary Communication of Design Critique in the Conceptual Design Stage
Computer tools provide little support for the communication of design concepts and problems across disciplines. Our objective is to help bridge the communication gap between architects...
Agent-Based Technology for Facility Design Software Integration
The application of a novel technology called Agent-Based Software Engineering to facility design software integration is presented. The technology is founded on the notion of design agents...
Dynamic Response of Bridges Under Traffic Loads
