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...
Public Utilities GIS: Promises and Pitfalls
Geographical Information Systems (GIS) and public utilities are natural partners. Municipal public utilities departments and other public works agencies rely on geographical information...
Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...
Combined Boundary Element and Finite Element Analysis of Composite Slab on Girder Bridges
In this paper, the coupling of boundary element and finite element methods and its application to analyze slab on girder bridges are studied. The boundary element method (BEM) is employed...
A Finite Difference Approach to the Modelling of Thick Bridge Decks
The finite difference method, although well known as an efficient numerical method, was applied in the past, in the case of slabs, only for the solution of thin slabs. In the present study,...
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...
Constructors' Approach to CIC Based on Preparation of Construction Production Information
To improve productivity in the construction industry; much research and development is being done - on CAD systems, construction management systems, robotics, computer graphics, etc. Many...
Algorithms for Efficient Real-time Traffic Assignment

A Real-Time Expert System for Freeway Incident Management in Orange County, California
This paper discusses the development of a prototype, multi-user, networked, real-time knowledge-based expert system (KBES) to provide decision support to California Department of Transportation...
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...
Developing an Integrated Database Structure for the Lifecycle of Precast Concrete Projects
This paper presents an integrated database structure for the storage and retrieval of information during the planning, design, manufacturing and construction of a structural precast concrete...
Modeling Facility Engineering Processes & Data Using the P-C Approach
A facility engineering process typically involves participants from different disciplines, several life-cycle phases, and many computer applications. In this paper, we propose the Primitive-Composite...
An Automated Database System for Construction Bidding
A number of probability-based bidding models have been developed to assist a contractor in preparing bids that improve chances of winning over the competition. Models based on utility...
Adaptive, Multi-Resolution Modeling of Construction Plans
The process of developing a construction plan is complex, taking many considerations and constraints into account. In contrast, the CPM paradigm of planning allows only the results of...
