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
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....
MIS for Implementing Multi Project Programs
The successful implementation of large or small capital improvement programs must include more than the management of schedule and cost. An effective Program Management Team must be concerned...
Uncertainty in Infrastructure Management
The difference between committed costs and actual expenditure is a margin of control in project management. By using a measure of uncertainty we construct a cost-risk evaluation framework...
Treating Uncertainty in the Design of Horizontal Curves
A model based on expected total cost minimization approach is developed for determining optimal horizontal curvature for highway sections. Expected total cost is defined as the sum of...
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...
Development of Simulation and Cost Models to Compare HSR and Maglev Systems
Both high-speed rail (HSR) and magnetically levitated systems offer comfortable and safe ground transportation at high speed. The cost structure and performance of these systems and their...
Application of the Maglev System in Germany
After the unification of Germany in 1991, the Federal Government decided to investigate Maglev links between the old and new Federal States to cope with the considerable increase of East-West...
