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...
Computer Estimating & Cost Control History & Evolution at Perini
Computers have played an important role in the construction industry, particularly in estimation and cost control. With increasing number of personal computers, and software packages in...
A Dynamic Mapping Application for an ATIS
A dynamic mapping application for an Advanced Traveler Information System (ATIS) is described. The application requires tracking maintenance vehicles so that paths can be displayed indicating...
Benefit-Cost Analysis for Optimal Budget Allocation to Bridges
The funding available for bridge improvements in the United States has been insufficient for many years. The limited budgets granted have generally been allocated based on Sufficiency...
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,...
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....
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
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...
Tie Model: A Crosstie Replacement Planning and Costing Model
The Tie Model described in this paper is a maintenance planning and life-cycle costing model for wood crossties. The model includes a number of different failure modules to predict crosstie...
Aggregate Quarry Operations?From a Railroad's Perspective
This paper describes a study which shows how a railroad company can ensure receipt of a cost-effective, high-quality aggregate product for ballast by monitoring selected quarry operations....
Evaluation of HSGT Systems Under Uncertainty
The basic themes of this paper are two-fold. First we investigate what planning style is likely to be most suited for planning an HSGT system, dependent on three interdependent key variables:...
California-Nevada Superspeed Train Experience and Outlook
The experience of the California-Nevada Superspeed Train is chronicled from its inception in 1970 to the present. The evolution of the route alignment and technology selection are presented,...
High-Speed Surface Transportation Cost Estimating
The cost of building and operating high-speed surface transportation (HSST) systems in the United States is a critical factor in determining their feasibility. Costs are difficult to estimate...
Maglev vs. High Speed Rail in the Quebec City-Windsor Corridor: A Comparison of Costs and Revenues
This paper reports an investigation of cost and revenue for high speed rail vs. maglev systems serving selected links in the Quebec City-Windsor Corridor (Canada). Information on the Corridor...
