Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....
A PC-Based Stochastic Project Scheduling and Costing Module
Project delays and cost overruns are very common in construction industry. This may be back-traced significantly to non or ill treatment of uncertainties that overwhelm construction projects....
SCHEREC: SCHedule RECovery System
Creating a revised plan requires experience and significant time. To lessen the effort involved, a knowledge-based system named SCHEREC (SCHedule RECovery) was developed which suggests...
An Integrated Approach To Repetitive Construction Planning
Repetitive construction projects are unsuited for the use of the Critical Path Method (CPM) for their scheduling. Statistical simulation techniques offer a scheduling alternative, but...
Managing Uncertainty in Project Planning and Execution: Introduction and Overview
This paper provides an introduction and overview of topics that are relevant to project design and management under conditions of uncertainty, with an emphasis on civil engineering projects....
Quantification of Cost Uncertainties Using Neural Network Technique
This paper describes the development of a neural network system for forecasting cost escalation in construction. The input of the neural network system consists of factors that have an...
Interpretive and Modelling Problems of Risk and Uncertainty in Bidding Techniques
This paper considers the implementation of policy, strategic and tactical bidding and the processes of devolution of the risk and uncertainty in a corporate management context....
Range Estimating -- User-Friendly Risk Analysis
This paper introduces the reader to Range Estimating - a user-friendly decision technology for project cost risk analysis. Although developed with the non-statistician in mind, Range Estimating...
Startplan: Producing Schedule Templates Using IRMA
The Information Reference Model for AEC (IRMA) is a generic information modeling standard to support computer-integrated construction (CIC). Although IRMA is still in a conceptual stage,...
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...
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...
State and Resource Based Construction Process Simulation
Stroboscope is a programming language for construction process simulation. The programming language provides access to the state of the simulation and to the properties of resources. It...
Multi-Objective Optimization of Construction Schedules
This paper focuses on the multi-objective deterministic and stochastic modelling and optimization of construction tasks scheduling. Of particular importance is a frequency need to satisfy...
Using Computer Programs to Develop As-Built Schedules
An as-built schedule documents how a project was built over time. It indicates the start and the end dates of each activity during the construction. This schedule is often used to evaluate...
Managing Uncertainty in Environmental Remediation Project Planning
The cleanup operations in environmental remediation (ER) process, a relatively new area of opportunity for the construction industry, is often avoided due to its perceived high risks....
Linguistic Analysis of Risk in Project Planning
Construction risk analysis models are mainly based on quantitative techniques which require numerical data. However, in many cases, the available information related to uncertainty factors...
An International Knowledge Database for Ground Improvement Geo-Systems
Ground improvement technologies have traditionally played an integral and important role in major geotechnical construction projects throughout the history of civil engineering and selection...
Case Storage of Planning Knowledge for Power Plant Construction
Schedulers consider a variety of constraints when they analyze a project to schedule the construction work for it. Often they will start from some schedule that they recall from a previous...
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....
