Scheduling of Multi-Story Buildings in a Constraint Environment
Scheduling involves the allocation of resources over a period of time in order to perform construction activities, satisfying project constraints. These constraints, if present, must be...

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...

An Integrated Acquisition, Storage and Retrieval Multimedia System for Constructibility Lessons Learned
Constructability is defined the optimum integration of construction knowledge and experience during conceptual planning, engineering, procurement and field operations to achieve overall...

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...

The Denver Airport: Managing a Megaproject
If the 53 sq mi, $2.7 billion Denver International Airport seems daunting in size, imagine trying to manage its construction. Supported by over 100 firms, the five year-long project is...

Sonic NDT for Infrastructure Assessment
Sonic Nondestructive Testing (NDT) techniques are valuable tools for assessing infrastructure. Relatively recent innovations in the field can reveal the internal conditions of concrete...

Barriers for Innovation and Technology Transfer in the Public Works Infrastructure R&D
Utilization of technologies and innovation to revitalize America's public works infrastructure is beset with barriers. Some critical barriers, identified through literature review and...

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...

Using Condition Indexes to Evaluate Local Railroad Track Networks
The U.S. Army Construction Engineering Laboratories (USACERL) have developed condition indexes for assessing track condition that apply to local railroads. Indexes were developed for the...

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...

An Integrated Design/Construction Research Program for Infrastructure Rehabilitation
The quality of America's infrastructure today is barely adequate to fulfill current requirements, and sufficient to meet the demands of future economic growth and development. This serious...

Patterns in the History of the Urban Infrastructure
Infrastructure construction has been marked not only by a cyclical funding pattern but also by occasional shifts in regard to government level of provision. That is, while some infrastructure...

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...

Comparison of Aqueduct Reconstruction & Tunneling
The Massachusetts Water Resources Authority (MWRA) is proposing to provide redundancy for the Hultman Aqueduct which transports water over a distance of roughly 27 km. (16.9 mi.) into...

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...

Infrastructure Planning for Private Sector Investment
To minimize the use of public resources for infrastructure development, major works are being initiated in Latin America with studies designed to attract capital investment from the private...

Risk Analysis of the Financial Viability of the New Denver Airport
A risk analysis of the financial viability of the New Denver International Airport, conducted for the U.S. General Accounting Office, showed it highly unlikely that the new airport would...

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...
