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...

How Many Observation Wells Does it Take to Find a Groundwater Contamination Plume?
A Bayesian data worth framework is developed to balance the benefits and costs of data collection. In addition to Bayesian decision analysis, tools from Monte Carlo simulation, numerical...

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....

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...

An Object-Oriented Scheduling Data Acquisition Model Using a Hybrid Expert System
Acquisition of scheduling data for construction project information management is a complicated task. Historically, there has been a fundamental disconnection between cost estimation and...

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...

Computer-Assisted Planning, Programming, Budgeting System (CAPPB)
This paper describes an information system called CAPPB (Computer-Assisted Planning, Programming, Budgeting System) developed at the U.S. Army Corps of Engineers Construction Engineering...

Computer Automation and Project Organizational Impact: A Conceptual Model
This paper presents a framework to effectively model the impact of change in the level of computerization on project organizations. A key focus is the changing relationships between project...

Personal Computer Model to Evaluate Performance of Construction Systems/Services
Worldwide competition has finally impacted the construction industry and facility managers. As manufacturers become more competitive, the cost of doing business becomes more critical....

A Decision Support System for Evaluating the Suitability of a Robotics System for a Construction Project
Development in the area of construction robotics/automation would require construction managers to critically evaluate the feasibility of replacing a conventional construction process...

A Goal Driven Approach to Discrete Event Simulation
Discrete event simulation is getting more attention as a tool for allocating construction resources. However, its usage is limited because it requires intensive knowledge in conducting...

A New Automated System for Decision Support in the Construction Industry
This paper describes a collaborative project to research and develop a computer based decision support system for the construction industry. The system is intended primarily for use during...

Using CADD Application to Support Construction Activities
This paper discusses how electronic CADD submittals from designers can be transformed into a format appropriate for construction planning and management. Currently, design drawings are...
