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...
An Overview of the Analysis and Design Techniques Used on the Main Tunnels of the SSC
Sophisticated numerical analysis and design techniques were devised for the Supercollider in order to produce a design which closely reflected the constraints of the construction processes,...
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...
Three Dimensional Simulation of Progressive Tunneling Process for Lining Design of Intersecting Tunnels in Soft Rock
This paper presents the results of the state-of-the-art three-dimensional nonlinear finite element modeling of progressive tunneling process and its comparison with field data. Reasonable...
Creative Design Using a Genetic Algorithm
Genetic algorithms provide a methodology for searching a space and are typically associated with optimization or classification problems. The possibility for genetic algorithms to produce...
A Real-Time Graphical Interface to a Two-Dimensional Groundwater Flow and Mass Transport Model
This paper describes the implementation of a graphical interface to the U.S. Geological Survey's Method of Characteristics (MOC) groundwater flow and mass transport model....
Conceptual Design Using Evolutive-Cognitive Computing Techniques
The paper concerns the development of a computer-based capability for conducting conceptual design using emergent(self-organizing) computing paradigms that arrive at a solution through...
Performance of Nanhua Dam During Construction
The pore pressure response and settlement during the construction of Nanhua dam were studied by several methods, including Hilf's method, laboratory stress path simulation and numerical...
An Investigation of the Reinforcing Effect of Stone Columns in Soft Clay
A proposed major extension to an iron ore handling yard was located in an area underlain by soft alluvial clay. Stone columns were proposed to limit settlement of rails supporting the...
Application of the Phase Change Process to One-Dimensinal Consolidation Behavior of Peat
In this study, based on the fact that the pore of fibrous peat consists of the macro (outer) pore between organic matters and the micro (inner) pore inside organic matter, an approximate...
Prediction of Low Level Vibration Induced Settlement
A prediction model of vibration induced settlement was developed for small to intermediate vibration levels (0.25-1.78 cm/s). Seven factors affecting vibration induced settlement such...
Comparison of Predicted and Measured Settlement of a Test Embankment Over Soft Soil
A test embankment was instrumented with six (6) settlement plates, three (3) vertical extensometers, two (2) inclinometers, and two (2) horizontal profilers in order to verify settlement...
Application of the Diflupress L.D. Field Test to Settlement Calculation
Electricite de France developed a new in situ measurement apparatus (Diflupress L.D.) in order to predict the delayed settlements that can appear under heavy constructions. From the experimental...
Measurements and Numerical Modelling of High Rise Building Foundations on Frankfurt Clay
Many high rise buildings were founded on Frankfurt clay on rafts applying average contact stresses in the order of 0.4 MPa. Beside rafts now piled-rafts are often used to reduce total...
Nonlinear Three Dimensional Analysis of Downdrag on Pile Groups
The downdrag on pile groups was investigated by using a numerical analysis and an analytical study. The emphasis was on quantifying the reduction of downdrag on piles in a group due to...
