Title: Network Diagram Analysis of a Construction Project Objective: To create and analyze a network diagram for a construction project using PERT CPM technique, identify the critical path and slack time (float time). Instructions: 1. Consider a hypothetical construction project, such as building a new house or a commercial building. 10 activities in the project are provided below. You must add 2 to 3 extra activities of your choice to the list so that you will have 12 to 13 activities in total. 2. Create a network diagram for the project, showing the activities and their dependencies. Use PERT CPM analysis to calculate the Earliest Event Time and Latest Event Time. 3. Identify the critical path for the project, i.e., the sequence of activities that determines the project duration. Calculate the project duration based on the critical path. 4. Identify the slack (float) time for each activity, i.e., the amount of time that an activity can be delayed without affecting the project duration. 5. Analyze the network diagram and identify any activities that could potentially delay the project. *** You are permitted to draw the figure by hand, but your list of activities/predecessors/duration must be type up and in a table format Activities, predecessors, and their duration are provided below: 1. Site preparation (clearing, grading, etc.) - Duration: 2 weeks; Predecessor: None 2. Foundation construction (excavation, pouring concrete, etc.) - Duration: 4 weeks; Predecessor: Site preparation 3. Framing and structural work (walls, roof, etc.) - Duration: 6 weeks; Predecessor: Foundation construction 4. Electrical and plumbing rough-ins (wiring, pipes, etc.) - Duration: 4 weeks; Predecessor: Framing and structural work 5. Insulation and drywall installation - Duration: 2 weeks; Predecessor: Electrical and plumbing rough-ins 6. Flooring and finish carpentry - Duration: 3 weeks; Predecessor: Insulation and drywall installation 7. Interior painting - Duration: 2 weeks; Predecessor: Flooring and finish carpentry 8. Exterior siding and roofing - Duration: 4 weeks; Predecessor: Framing and structural work 9. HVAC system installation - Duration: 3 weeks; Predecessor: Framing and structural work 10. Final cleaning and inspection - Duration: 1 week; Predecessor: Interior painting
