The Job-Order Contracting Solution
A new method of contracting, Job Order Contracting, combines many contracts into one administered by one project team. They are competitively bid, indefinite delivery, indefinite quantity,...

A New Angle on Ground-Water Remediation
When engineers from Black & Veatch Waste Science (BVWS) went to Tinker Air Force Base to examine the site of a hazardous waste cleanup job the service had hired them for, they...

Multimedia in Civil Engineering
Multimedia inspires so many claims and hype that it can be hard for engineers to figure out what's real and what's not. The truth is that multimedia holds great...

Circle Integration
Based on the results of proof-of-concept experiments, we propose that an integrated suite of software tools can support both automation and integration of several components of AEC design...

Functional Analysis of the Envelope Design Process for Integrated Building Design
Building envelope failures account for a great portion of building failures. The number of envelope deficiencies would be reduced if the design process was integrated. Integration would...

Construction Problem Solving in a Cooperative Distributed Agent Environment
This paper outlines the research being undertaken by the authors to determine how experts develop solutions to construction problems in a cooperative distributed agent environment which...

Improved Computer Simulation of 3D Wind Flow Around a Building
A two-layer method combining the k-? model with the one-equation model near the wall has been tested in computing the wind conditions around a cubic building. In contrast with the simple...

Different Methods to Compute Pollutant Dispersion Around Buildings
Different methods to approximate the advection terms currently in use are reviewed. Holly-Preismann (HP) cubic interpolation using method of characteristics, Chapeau function (CF) method...

Intentions and Credences ? An Australian Approach to Computerised Building Regulation
In the past, computer representation of building regulations has addressed a series of prescriptive requirements. Compliance with each requirement was essential and the only relationship...

Standards Processing 2000
Current software applications fall short of meeting user requirements for `intelligent' electronic access to building codes and standards. Hypertext is a useful tool, but it only assists...

The Context?Oriented Model: An improved Modeling Approach for Representing and Processing Design Standards
Current electronic design evaluators employ one of three primary computational models to represent a design standard: the Condition/Consequent, Object-Oriented and hybrid models. The problems...

Nonlinear Analysis of Structural Frameworks Using Supercomputing Techniques
Applications of vectorization and the parallel processing technique of multitasking in the elastic nonlinear analysis of building frameworks are presented. The proposed algorithm is implemented...

Representing Design Cases Based on Methods
This paper discusses an approach to representing design cases using the methods used in solving specific design problems. This differs from the conventional representation of design cases...

Advances and Challenges in Case Based Design
The application of the case-based design (CBD) method to preliminary building design provides an opportunity to overcome problems associated with traditional computer-based design methods....

Representation of Vertical Constraints Knowledge for Scheduling Multi-Story Projects
Multi-story projects are characterized by many repetitive units or typical floors that involve identical activities repeated consecutively from one floor to the next. Horizontal logic...

Simplified Simulation Model Development for Construction Projects
The application of discrete event simulation tools is extremely beneficial in improving the efficiency of building construction activities. Simulation is used to evaluate construction...

Selecting Precast Concrete Building Systems
The development of an integrated computer system to assist in the selection of precast concrete (PC) building systems is described. StructNet, a neural network program, identifies possible...

Scaling Up is Hard to Do: Experiences in Preparing a Case-Based Design Aid Prototype for Field Trial
We seek to improve the conceptual design process for complex artifacts such as buildings by offering designers access, through an on-line hypermedia library, to documentation and evaluations...

Precedents in Design: A Computational Model for the Organization of Case Knowledge
A computational model of for the organization of case knowledge of precedent knowledge is developed. The model is composed of distinct chunks of knowledge called design stories. A formalism...

Case-Based Design in the SEED System
We present the requirements for case-based design in a software environment to support the early phases in building design and outline an approach to satisfy them. We briefly discuss implementation...
