Final answer:
To create a two-level WBS for the Brooklyn Bridge, we consider major phases like Project Management, Design, Foundation Construction, and Testing followed by specific work packages including permitting, engineering calculations, pier construction, and safety inspections.
Step-by-step explanation:
Developing a Work Breakdown Structure (WBS) for the Brooklyn Bridge
To develop a two-level Work Breakdown Structure (WBS) for the building of the Brooklyn Bridge with at least 16 work packages, one must take into account various phases of construction and the key deliverables associated with each phase. Here is an example of how the WBS could be outlined:
Level 1: Major Phases of Construction
- Project Management and Administration
- Design and Engineering
- Site Preparation and Foundation Construction
- Pier and Tower Construction
- Superstructure and Deck Assembly
- Cable Spinning and Suspenders
- Roadway, Pedestrian, and Ancillary Structures
- Testing, Inspection, and Commissioning
Level 2: Work Packages
- Creation of project documents and permits
- Engineering analysis and calculations
- Architectural design and modeling
- Environmental impact assessment
- Site excavation and land grading
- Foundation piling and footings
- Construction of the south pier
- Construction of the north pier
- Tower erection on the south pier
- Tower erection on the north pier
- Steelwork for superstructure assembly
- Precast concrete segments for the deck
- Installation of main suspension cables
- Attachment of suspender cables and deck
- Installation of roadway systems and barriers
- Final inspections and safety certifications
It is crucial to explain that each work package represents a group of tasks that form a deliverable at the lowest level of the WBS. This ensures a clear, detailed, and organized construction plan; essential for a project as complex as the Brooklyn Bridge.
