Resource Constrained Time-Space Scheduling Model
This study aims to develop a resource constrained time-space scheduling model, mainly aiming application to pipeline laying world for gas supply under roads in urban area. This model can...

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...

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...

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...

After the Blast
On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...

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...

Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...

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...

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...

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...

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...

Digital Imaging as a Design Tool
On most engineering projects, schematic drawings offer a technical representation of a structure to clients. For staff or the public who are not technically knowledgeable, though, schematics...

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...

Risk Analysis Methodology for Life Cycle Benefit Analysis of Innovative Construction Technologies
The adoption of new construction technologies into practice moves very slowly since participants in the construction processes are extremely risk adverse. Innovation barriers are characterized...

Case Study of Electronic Toll Collection in the Central Artery/Tunnel Project?Boston
The purpose of this paper is to discuss the issues involved in incorporating new technology, specifically electronic toll collection into a large, long-term construction project. The paper...
