A simple house project can be structured as follows (9 work packages total): • Design: Ground plans + External design • Structure: Excavation + Foundation + Roof + Frame • Services: Electricity + Plumbing + HVAC Create the Work Breakdown Structure (WBS) of the project described above, using a tree structure. Use the following numbering system: • ‘1’ for the top level (House Project) • ‘1.1’ onwards for the second level • ‘1.1.1’ onwards for the third level

Draw manually a WBS for your assumed building project. Mention duration for each activity of your project and total completion time.
For one of the construction projects, draw the (PERT) network diagram and find the following:
1. Develop a network diagram based on the logical sequence of activities 2. The WBS should be further broken down into around 25 activities
Checklist of activities during construction of building. Be specific and complete with the activities.
