Time-Dependent Analysis of Nonprismatic Curved PC Box Girder Bridges
The purpose of this paper is to present a step-by-step computer method for predicting the deflection and stress distribution duo to creep and shrinkage of concrete in nonprismatic, curved,...

Project Modeling and Data Standards for AEC
Computer-integrated construction (CIC) will provide the architecture, engineering, and construction (AEC) industry with improved computer tools and will support an overall trend towards...

DScheduler: A Deductive Database for Scheduling Building Construction Tasks
Computer applications in the construction domain, such as construction scheduling and estimation, require a large amount of data. Reasoning with complex data is facilitated by Artificial...

Construction Information Management
Use and characteristic of Information Systems in the organizations has been changed significantly. These systems are not functionally oriented any more and they do not have any bias toward...

Containing Construction Change with Computers
This paper discusses the benefits of managing construction change orders with computers over manual methods. Construction contracts formulate change procedures that are often at odds with...

Space Schedule Construction
The layout of temporary facilities on a construction site is affected by changes in a construction schedule, including changes in activity duration, resource selection, and resource allocation...

Using Product Models to Plan Construction
The conceptual design of the CasePlan case-based planning and scheduling system is presented. Case-based reasoning is a promising technique for capturing the expertise of contractors who...

Pre-Design Planning with Intelligent Project Development Brochure (IPDB) System
The functional design criteria and other technical requirements are to be established during the pre-design planning stage of a project. At this pre-design stage, the formulation of the...

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...

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...

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...
