highway bridge, the six major components are:
1. Procurement
2. Field mobilization and site work
3. Pile foundations
4. Concrete abutments and wing walls
5. Deck
6. Finishing operations
In turn, each of these major project segments can be broken down into its subcomponents to form the second level of the WBS. For example:
4. Concrete abutments and wing walls
4.1 Abutment #1
4.2 Abutment #2
Similarly, each of these can be further subdivided.
4.1 Abutment #1
4.2.1 Forms & rebar abutment #1
4.2.2 Pour abutment #1
4.2.3 Strip & cure abutment #1
4.2.4 Backfill abutment #1
4.2.5 Rub concrete abutment #1
A complete WBS for the project is shown in Appendix C. The WBS has a number of other applications in addition to facilitating the planning process. The project team who will oversee the work should develop the WBS
