Several building technologies and practices have emerged in recent years as alternatives to traditional design and construction in meeting cost, time, and quality goals of owners and builders. Some of these methods have been adopted within private industry, but have not yet seen wide use for military construction. However, legislation from Congress has mandated that the military services now consider using such methods when they have a potential to reduce Federal expenditures for construction. The U.S. Army Corps of Engineers (USACE), which is responsible for construction within the Army and Air Force, has a limited background in using alternative methods due to the long reliance on traditional approaches to facility procurement. To expedite the learning process and capitalize on lessons learned from projects using alternative methods, USACE proposed that knowledge base be prepared. The U.S. Army Construction Engineering Research Laboratory (USACERL) is responsible for its development. This report describes the knowledge base concept and prototype. The prototype uses dBase III Plus software and IBM-compatible personal computers. Data will be both factual listings (e.g., project name, date, location) and informational (e.g., comments about a problem in the design phase). Access will be via a local data base containing installation-specific projects and through a centralized mainframe system containing USACE-wide projects. Although useful by itself, the conceptual knowledge base would be a more effective tool if it were incorporated into an expert system. Such a system would provide support in addition to an advisory function. (aw).
This sixth IMKB volume attempts to synthesize research done over a longer period of time in a reference book format. The work presents in survey articles the efforts to study foundations and applications of conceptual modelling in various environments. The motivation of these efforts is the fact that conceptual modelling and knowledge representation together with various kinds of inference systems are important subfields in the design and use of information systems. The modelling problem is essential in many disciplines, such as database design, knowledge engineering, logic, artificial intelligence, cognitive science, philosophy, linguistics, etc. A central and comprehensive bibliography is included.
In the last decades information modelling and knowledge bases have become hot topics not only in academic communities related to information systems and computer science, but also in business areas where information technology is applied. This book includes papers submitted to the 17th European-Japanese Conference on Information Modelling and Knowledge Bases (EJC 2007). The EJC conferences constitute a world-wide research forum for the exchange of scientific results and experiences achieved in computer science and other related disciplines using innovative methods and progressive approaches.

Sustainable Construction Technologies: Life-Cycle Assessment provides practitioners with a tool to help them select technologies that are financially advantageous even though they have a higher initial cost. Chapters provide an overview of LCA and how it can be used in conjunction with other indicators to manage construction. Topics covered include indoor environment quality, energy efficiency, transport, water reuse, materials, land use and ecology, and more. The book presents a valuable tool for construction professionals and researchers that want to apply sustainable construction techniques to their projects. Practitioners will find the international case studies and discussions of worldwide regulation and standards particularly useful. - Provides a framework for analyzing sustainable construction technologies and economic viability - Introduces key credit criteria for different sustainable construction technologies - Covers the most relevant construction areas - Includes technologies that can be employed during the process of construction, or to the product of the construction process, i.e. buildings - Analyzes international rating systems and provides supporting case studies
Managing IT in Construction/Managing Construction for Tomorrow presents new developments in:- Managing IT strategies - Model based management tools including building information modeling- Information and knowledge management- Communication and collaboration - Data acquisition and storage- Visualization and simulation- Architectural design and
Knowledge-Based Process Planning for Construction and Manufacturing describes a knowledge-based system architecture that is used to develop process planning systems called PLANEX. This book explains that PLANEX is a domain-independent, knowledge-based process planning system architecture. Starting from a description of the physical artifact to be constructed or manufactured, PLANEX generates the set of activities used to create the artifact. These activities, with their required resources, are linked into a process planning network which can be used in project scheduling or management. This text also reviews the concepts, requirements, and resulting architecture of PLANEX, including detailed descriptions of applications of the system in construction and manufacturing. This publication is recommended to engineers, architects, and specialists interested in construction and manufacturing process planning.
