Question

A team needs to build a shed foundation, which can be done once the trenches are dug. The trenches will take 2 days and pour foundation will take 1 day. They need to wait 2 days for the foundation to cure, during which time they can install the underground electrical wiring, which will take 3 days. They can then build a brick wall up to just above ground level, which will take 2 days. When is the soonest that the electrical contractor can start on the underground electrical wiring if the finish-to-start relationship between pour foundation and the wiring activities is the only discretionary dependency?

Answer 1

The finish-to-start relationship between pouring the foundation and installing the underground electrical wiring determines when the electrical contractor can start.

Step-by-step explanation:

In project management, the finish-to-start relationship represents the dependency between two activities, where the second activity can only start once the first activity has finished. In this case, the finish-to-start relationship exists between pouring the foundation and installing the underground electrical wiring.

The soonest that the electrical contractor can start on the underground electrical wiring is as soon as the foundation has been poured. According to the given timeline, pouring the foundation takes 1 day and the trenches take 2 days. Therefore, the earliest the electrical contractor can start is on Day 3, which is after the trenches have been dug and the foundation has been poured.
