A good WBS encompasses requirements leading to hand over of a project and can be used as the basis for detailed costing and scheduling. There is no one-size-fits-all when it comes to creating a WBS site specific projects. However, there are eight general means of divisions that can be used, depending upon the needs of your project.
1. Trade or Sub-Contractor (Labour)- splitting the project up into the various trades required for the project, e.g. excavator, plumber, concreter, carpenter.
2. Building Element (Stages) - breakdown the project based upon the main components as milestones of the structures, e.g., sub-structure, transfer slab, frame, internal lining etc.
3. Location on site - breakdown the project according to milestones in-situ, e.g., basement, ground floor, roof.
4. Material Types – The breakdown of the project in relation to the materials to be used categorised by the construction stages, e.g. footings, ground floor stairs, level one slab.
5. Sequence of Activities (Recognise Dependencies) – This highlights tasks that need to be completed before the next stage of construction can commence, e.g., excavation, footings, sub-floor floor works.
6. Organisational Structure - this involves the breaking down of key stakeholders involved in the project, e.g. client, local council, design consultants.
7. Contractor’s Responsibilities – The breakdown of key project deliverables into the work packages contractors are responsible for completing.
8. Cost Planning - total costing can first be itemized for different types of costs, such as materials and wages. Further breakdowns can then outline different estimates for each cost in more detail, such as information on payment dates, etc.
