Bjorn and Thor are plumbers who have been scheduled to work on the construction of a new school building. Just before the start of the project, Bjorn broke his arm and cannot work on the project. Now Thor has to handle his own activities as well as Bjorn's. Level the project Gantt chart so that Thor is responsible for activities 3, 4, 6, and 7.

What would the new project estimated completion date be? New project completion date would be earlier by 1 day. earlier by 2 days. extended by 1 day. extended by 2 days. Compute the early, late, and slack times for the activities in the network that follows, assuming a time-constrained network. Note which activities are critical, and determine the critical time-constrained project duration. Note: Recall that in the schedule resource load chart the time-constrained scheduling interval (ES through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the project.
