The Kettering Community Demonstration Project Non-Point Pollution Control and Environmental Enhancement Program
With the advent of the U.S. EPA's municipal/ industrial NPDES and Coastal Zone Management programs the development of effective non-point pollution control programs has become the most...

Development and Implementation of Stormwater Utilities in Texas Cities
As more Cities begin to understand and feel the financial impact of EPA's Non-Point Discharge Elimination System (NPDES) stormwater regulations on their budgets, many are turning to stormwater...

Projecting Customers Using a GIS Land Use Forecasting Model
The Salt River project originally developed the Land Use Forecasting Model to understand the pattern of urbanization of agricultural and desert land in metropolitan Phoenix. The model...

F. E. Everett Turnpike: An Application of MOSS
MOSS surface modeling software is being used successfully by Fay, Spofford & Thorndike, Inc., on a major project for the New Hampshire Department of Transportation to make improvements...

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...

A Stochastic Cost Engineering System (SCENS) Applied to Estimating and Tendering for Bill of Quantities Contracts
In many countries, contracts based on bill of quantities are very common in construction industry. Although estimating and tendering are overwhelmed by uncertainties, the common practice...

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...

Knowledge and Information Processing with Drawing Objects in Construction Phase
Knowledge processing by CAD systems poses challenging problems for the efficient integration of design and construction processes. While CAD systems have been applied to various phases...

Computer Application in Analyzing Change Order Work
In heavy construction, particularly on large tunnel projects, numerous tasks are often performed and inspected simultaneously. The project specifications and contract documents require...

Advanced Construction Technology System
The Advanced Construction Technology System (ACTS) is a computer database for the classification, documentation, storage and retrieval of information about emerging construction technologies....

Using Data Flow Diagrams to Study Communication Process Between Construction Project Participants
The Architecture-Engineering-Construction (AEC) industry is characterized as being highly fragmented. A large number of diverse organizations participate in the planning, design, and construction...

An Automated Cost Planning System (ACPS) for Construction Projects
This paper suggests an automated cost planning system (ACPS) for planning and scheduling construction projects. The major objective of this system is to further the use of CPM as a planning...

A Rezoning Procedure for Finite Element Analysis of Rubber-like Materials
In this paper, we propose a rezoning procedure for finite element analysis of rubber-like materials. Rezoning procedures connect the distorted mesh and the newly created and undistorted...

The Design Navigator
A building design system has no bridge the gap between the complexity of the design information, resulting from the artifact itself, the large amount of laws, regulations, and restrictions,...

Conceptual Cost Estimating: A Hybrid Neural-Expert System Approach
This paper presents a hybrid neural-expert system approach for developing conceptual cost estimates based on historical data of construction projects. The proposed hybrid neural-expert...

Optimal Resource Leveling Using Integer-Linear Programming
The project manager strives to schedule various project tasks as efficiently as possible. But, resources available to the project manager are limited. A problem arises when a schedule...

Algorithms for Efficient Real-time Traffic Assignment
Fast algorithms are essential to accomplish real-time traffic assignment for optimal routing or traffic prediction under ATMS/ATIS. User-equilibrium and system-optimal traffic assignment...

Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
