The document provides instructions for constructing a network diagram for a construction project to build a new gymnasium. It includes an activity list with 37 tasks required to complete the project, along with the duration and predecessor tasks for each. To construct the network diagram, one must identify each task as a node and use arrows to show the precedence relationships between tasks based on which must be completed before others can begin. This will provide the schedule for the construction of the new gymnasium.
