Total Quality Management for Information Technology
Recently, there has been an increased awareness in the AEC firms toward Total Quality Management (TQM). Many AEC firms and the public sector started to look seriously at TQM. The reason...
Using an Object-Oriented System and a Conceptual Building Model to Represent Architectural Information During Early Design Phases
In this paper we are to present an object-oriented system based on a conceptual building model for handling architectural information during early design phases. This system and model...
Simulating Paving Fleets with Non-Stationary Travel
Proper selection of equipment and fleet size can yield substantial savings in both time and cost. A simulation model of asphalt-paving operations is presented and impacts of non-stationary...
Maintaining Engineering Drawings in the '90s
With the technologies available today, it is possible to begin a scanning system at a rather small or limited scale - and still realize a quantifiable return on investment. In the 90's,...
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...
Competitive Advantage of Using Computers in Structural Design
More and more structural analysis and design work is done using computers. The trend will continue because the software is becoming more powerful and the cost of computers is falling....
Decision Support Systems in Construction Management
A Decision Support System is defined as a computerized tool to improve the effectiveness of decision-making in semi-structured tasks (e.g., tasks that require a manager's judgmental input....
Model-Based and Interactive Planning for Predictive Plant Maintenance Management
Maintenance of process in power plants represents about 30% of the operating cost of these plants, including the cost of repair labor, materials and out side services but not the cost...
Fit to Drink
Amendments to the Safe Drinking Water Act (SWDA) in 1986 greatly expanded the number of contaminants subject to regulation and significantly beefed up water quality treatment and monitoring...
Highway Investment Analysis: The Next Generation
The Department of Transportation has developed and is now testing a state-of-the-art modeling procedure which simulates highway improvement selection decisions based on the relative benefits/cost...
Cost-Benefit Evaluation of Network Level Pavement Management
This paper presents a cost-benefit analysis prepared for senior management. It uses the Alberta pavement management system as the primary case, and the Arizona PMS system as the second...
TRACS: A Tool for Track Infrastructure Management
