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...
Probabilistic Modeling of Scheduling Uncertainty: Methods and Tools
This paper provides an overview of probabilistic project scheduling methodologies and tools. It emphasizes the practical application of Monte Carlo simulation in modeling activity durations....
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...
An Integrated Computer Model for Project Schedule Updating
Current schedule updating techniques rely mainly on field reports to specify completed work. Information provided in these reports are then manually summarized, analyzed, and input to...
Alternative Decisions for Space-Based Scheduling in Multi-Story Projects
SCaRC (Space-Based and Resource-Based) is a prototype knowledge-based scheduling system that acknowledges work space as a scheduling constraint. The SCaRC system comprises different scheduling...
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,...
Facilitate Delay Claim Analysis with As-Built Schedule Databases
A computer-based As-Built Schedule Database can provide a useful tool for the investigation of project performance. The facts recorded in the database may be used to identify actual sequential...
Deep Dig, Tight Squeeze
Since it opened in 1928, the North Station/Boston Garden Complex has secured a firm place in local history. Boston Garden, home of the Bruins hockey and Celtics basketball teams, has been...
Concrete over the Connecticut
The existing Baldwin Bridge carrying I-95 across the Connecticut River between Old Lyme and Old Saybrook, Connecticut, constructed in 1948, is functioning at maximum capacity with modern...
Machine-Friendly Facility
Cargo facility automation makes more efficient use of space, reduces labor and speeds operations. These are critical factors at New York's John F. Kennedy International Airport�currently...
Cost and Schedule Baseline Management in the OCRWM Program
The Department of Energy's Office of Civilian Radioactive Waste Management has established a baseline change control system to support their program control system. The program control...
A CAD-Based Construction Simulation Tool Kit for Construction Planning
Current planning and scheduling techniques place considerable reliance on the planners judgement, imagination and intuition. The result of such techniques is typically lengthy text reports...
Linear Scheduling: A Practical Implementation
This paper describes the features and use of a family of planning structures that provides the basis for a superset of the traditional critical path method which includes linear scheduling....
An Automated Cost Planning System (ACPS) for Construction Projects
This paper suggests an automated cost planning system (ACPS) for planning and scheduling construction projects. The major objective of this system is to further the use of CPM as a planning...
Optimal Resource Leveling Using Integer-Linear Programming
The project manager strives to schedule various project tasks as efficiently as possible. But, resources available to the project manager are limited. A problem arises when a schedule...
Design Information Hierarchy for Construction Method Selection Process
The Construction Project Planning (CPP) stage is a critical stage for the success of a construction project. This stage lays the framework upon which most of the construction decisions...
An OOP Model for Scheduling of Repetitive Projects
Repetitive projects are characterized by the presence of large number of repetitive activities, along with a number of non-repetitive activities. Each of thee two types of activities requires...
Exchanging Layout and Schedule Data in a Real-Time Distributed Environment
Unpredictable site conditions and unforeseen changes in construction work may result in inefficiencies due to a shortage of work space and difficult access to critical areas on site. This...
Incorporating Weather Effects in Project Simulation
Planning of construction operations and projects must take into account weather conditions and the resulting impacts on the project schedule. Predetermination of weather and its resulting...
Classifying Constructability Information
Integration of constructability information in the early stages of a project is known to provide significant savings opportunities for cost and schedule. One critical part of such a program...
