Construction Scheduling

The second module introduces bar or Gantt charts and how they are used as scheduling tools. Bar charts represent a project work item or activity as a time scaled bar; the length of which represents the planned duration of a construction activity.

In this module, learners will create Activity Precedence Diagrams, also referred to as Activity on Node Diagrams, which graphically represent the construction activities in a project and their relationships.

This module provides an overview of the types of construction activity relationships encountered in a construction project and how to represent them in an activity precedence diagram.

Forward and Backward Pass Calculations are covered in this module. Forward Pass Calculations determine the minimum dates at which each construction activity can be performed and, ultimately, the minimum duration of a construction project. Backward Pass Calculations compute the latest dates by which each construction activity can be performed without increasing the projects minimum duration.

Professor Odeh discusses the importance of critical path in this module including what it is and why it is important. Learners will identify a critical path in a project and how to determine a critical path in different relationships.

Professor Odeh introduces the types of floats in a construction project including; total float, free float, interfering float and independent float.

In this module, the difference between working dates and calendar dates is explained and how to chart both in a project plan.

Activity on Arrow diagrams are the topic for this module. Professor Odeh will discuss how to draw an activity on arrow diagram and how to number the nodes. Forward and Backward Pass calculations and determining the duration of a project are also covered.

The Program Evaluation and Review Technique (PERT) is introduced in this module which relates to uncertainty in estimating the duration of construction activities in a project schedule. PERT helps project managers determine the probability of a project being completed in a certain number of days.

Jennifer Buermann, of the STV Group, discusses the role of the scheduler in a construction project and how to determine if a project is on track to meet the estimated goals. Also covered are ways to adjust to ensure the project stays on track.

Professor Odeh introduces linear construction; projects that have linear, or repetitive, properties. Also covered is the Line of Balance scheduling method which is a way of allocating resources for repetitive processes.

Dareen Salama, of the STV Group, discusses the technology applications used for scheduling. Dareen provides an overview of the applications used for scheduling development, schedule analysis, sharing and collaboration and visualization.

Christopher Toomey, Senior Vice President of AECOM Global Programs, discussed scheduling for large programs also known as the Integrated Master Scheduler. Mr. Toomey illustrates how to develop and maintain the Integrated Master Schedule and identifies key features.

Dr. Eduardo Gamez, Deputy Director of Risk Management for AECOM, introduces Risk Allocation and Planning. Dr. Gamez discusses the importance of formal risk management and how to use risk assessment as a support tool for planning and scheduling.

Sam Spata, of MethodLean, discusses lean design and lean scheduling. The concept of Flow is introduced, the process of how to get from the beginning to the end of a project, as a measurable addition of value.
