Department of Transportation


The New Jersey Department of Transportation (NJDOT) uses two types of diagrams to describe the activities and products of a capital transportation project, Network Diagrams and Work Breakdown Structure (WBS) Diagrams.

Network Diagrams

Network Diagrams show the activities to be followed and the relationship of these activities. NJDOT has created a new network diagram to guide the project execution of capital transportation projects. All projects do not follow the same prescribed steps of work. The network diagram for a specific project will be customized to fit that project. Project Managers need to prepare an accurate and complete set of construction contract documents that comply with all NJDOT and Federal Highway Administration (FHWA) policies and design standards, keeping in mind the need to implement highway and bridge improvements quickly and economically.

The network diagrams are used as a basis for creating a detailed project schedule and for managing discrete work packages.

The following network diagrams are available:

Work Breakdown Structure Diagrams

Work Breakdown Structure Diagrams show the products, and the breakdown of products, of a capital transportation project. NJDOT’s WBS diagram shows the products of a phase or process and how the products relate to each other. Specifically, a WBS diagram shows how individual products may be grouped together to create a top level product such as the Concept Development Report. The work breakdown structure is utilized to create scope statement templates for each phase of work. WBS dictionaries provide additional description for WBS products.

The following WBS diagrams and dictionaries are available:

The files are in Portable Document Format (PDF) and will need Adobe Acrobat Reader (available at our Adobe Access Page).
