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:

• Concept Development Phase (pdf 164k)
• Preliminary Engineering Phase (pdf 286k)
• Final Design Phase (pdf 407k)
• Construction Phase (pdf 101k)

The following Limited Scope network diagram is available:

• Limited Scope Concept Development Phase Network Diagram (doc 245k)

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:

• Project Delivery Process High Level WBS (pdf 71k)
• Problem Screening Phase WBS (pdf 88k)
• Problem Screening Phase WBS Dictionary (pdf 159k)
• Concept Development Phase WBS (pdf 142k)
• Concept Development Phase WBS Dictionary (pdf 291k)
• Limited Scope Concept Development Phase WBS (pdf 336k)
• Preliminary Engineering Phase WBS (pdf 175k)
• Preliminary Engineering Phase WBS Dictionary (pdf 214k)
• Final Design Phase WBS (pdf 185k)
• Final Design Phase WBS Dictionary (pdf 288k)
• Limited Scope Final Design Phase WBS (pdf 197k)
• Construction Phase WBS (pdf 187k)
• Construction Phase WBS Dictionary (pdf 80k)
