Time-Space Tradeoff Strategies for Space-Schedule Construction
Space availability on a construction site can have a major impact on the efficiency and constructability of a project. Especially when space is limited, tradeoffs between activity sequencing,...

Integrated Product Models
A review is made of current STEP standards efforts to develop integrated product models, using the Express language. An example of a building wall is presented, along with some general...

Extended Topology in Building Design Systems
An important aspect of CAD systems for building design concerns the description of the form of the building, the definition of operation on that form and the way these operations are offered...

Integrated System Environment Using an Object-Oriented Project Model with Multiple-Views
This paper describes the development, present status and future directions for PMAPM, an object-oriented project model designed to facilitate information sharing along the paths through...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...

Application of the FESWMS-2DH Software to Solve the Navigation Problem at EL-Menya Bridge in Egypt
The purpose of this paper is to introduce the application of a two-dimensional Finite Element Surface Water Modelling System on a navigation problem located along the Nile river in front...

Toward Integrated Models for Structural Design
The paper presents research toward integrated product and process models for structural design in which and each entity in the product model describes information used by activities in...

Creating Construction Documents from 3-D Computer Models
Structural engineering tasks can be broken down into three major phases; analysis, design and construction document production. Although automation techniques have focused on these phases...

Multimedia Based System for Analyzing Production Organizations
Construction operations involve many complex operations and relationships. This paper deals with data gathering for productivity improvement-studies, process modelling and simulation of...

Comparing Two OODBMSs: An Application Developer's Perspective
Advances in database management technology lead application developers to consider new implementation options such as Object-Oriented Database Management Systems (OODBMSs). Current OODBMS...

A Sketch is Worth a Thousand Rule Traces
The paper presents techniques for augmenting communication among building designers by providing (1) interdisciplinary explanation facilities to visualize and annotate CAD models, such...

A Formal Product/Process Model for Engineering
This paper describes an extended object data model which is suitable for modeling complex design information. The model provides extensions to object oriented model by providing explicit...

Macroelement Model for Shear Wall Analysis
An efficient modeling scheme for static and dynamic analysis of reinforced concrete shear walls in the inelastic range is presented. The macroelement model of the shear wall is composed...

Optimal Markup Policy in Sequential Competitive Bidding
Construction firms encounter resource constrains in their business operations. However, current competitive bidding models fail to consider the impact of a firm's constrained resources...

Interactive Cost Estimating During Design
This paper describes a model, called the Automated Interactive Cost Estimating System (AICES), which gives users access to reinforced concrete cost information that is sensitive to variations...

A Value Chain Model to Support Business Process Reengineering in Turnkey Contracting Firm
This paper discusses important factors of BPR as it is related to the use of information technology in the E&C industry. It then presents an industry value chain model from the...

Simulating Learning Development for Construction
This paper presents the methodology used to model the learning development phenomenon in the CYCLONE format using the Boeing learning curve. CYCLONE is a discrete event process interaction...

Extensions of Finite Element Dental Stress Analysis
Some two dimensional models for stress analysis of dental crowns are examined and compared in relation to boundary conditions and some other issues in finite element analysis. The current...

Rotating Crack Model and Fracture in a R/C Medium
In this study the potential of the development of cracks in the members of a reinforced concrete large panel structure is considered. The analysis is carried out using finite element modeling...

Numerical Modeling of Initial Ground Movement in an Instrumented Superconducting Super Collider Shaft
A 5.5 m diameter shaft was sunk into a rock formation of Taylor Marl to a depth of 61 m at the Superconducting Super collider (SSC) site. Numerical modeling using finite difference analysis...
