An Assessment of the Joint Factor as Used in the Modified MEXE Method
The finite element method has been used to examine the joint factor in the modified MEXE method which is documented in the publications (BD21/93 and BA16/93) by the Department of Transport...

A Decision Support System for the Expansion of International Operations of A/E/C Firms
The changing trend of the construction industry will require A/E/C firms to consider expanding operations in the international construction market arena. This paper presents a conceptual...

An Integrated Computer Model for Project Schedule Updating
Current schedule updating techniques rely mainly on field reports to specify completed work. Information provided in these reports are then manually summarized, analyzed, and input to...

Overlaying Digital Images with 3-D CAD to Document as Built Construction
A persistent problem in construction has been documenting changes which occur in the field and preparing as-built drawings. The accuracy and completeness of field measurements is often...

Building Product Model, A First Brick in Computer Integrated Construction
This paper describes the development of a product model as a basis for an information system. This new approach is based on modelling functions of building units rather than physical entities...

Developments to the IRMA Model of AEC Projects
The rapidly advancing fields of information technologies (IT) for AEC and computer-integrated construction (CIC) rely on the ability to represent and exchange information about AEC projects...

Design and Implementation of a Database for Seismic Evaluation of Structures
The seismic evaluation of large structures, such as bridges, requires a comprehensive framework for managing the data. An evaluation typically involves the dynamic analysis of a number...

Transactional Support for Concurrent Finite Element Analysis & Design
The finite element (FE) analysis and design process deals with large amounts of complex engineering data. Although sophisticated techniques have been developed for computer-aided FE analysis,...

Deductive Databases in Engineering
Many engineering systems can be modeled in terms of objects and relationships among objects. As generalized relational databases, deductive databases provide a suitable tool for representing...

SCADA System Controls Combined Sewer Overflow Regulation System to Optimize Wastewater Collection
The Metropolitan St. Louis Sewer District's Overflow Regulation System (ORS) project uses computer control of a wastewater collection system for the purpose of combined sewage overflow...

Overflow Elimination Benefits from GIS Based Technology
Elimination of wet weather overflows through the rehabilitation of infiltration and inflow defects requires careful analysis of the collection system. The integration of geographic information...

Sewers and Computers
