When would the construction phase overlap occur?

The construction phase overlap occurs primarily when the project is behind schedule. This scenario often necessitates an integrated approach, where subsequent phases are initiated before the previous phases have finished. The primary goal is to recover lost time and ensure that the overall project timeline can be adhered to.

When a project falls behind schedule, project managers may decide to start work on future phases of construction while earlier phases are still in progress. This can involve mobilizing resources and teams to overlap activities, thereby accelerating progress and mitigating delays.

In contrast, being ahead of schedule usually allows for a more measured approach, while changes to plans or increasing the workforce do not inherently indicate that there is overlapping of phases. Instead, these situations are more about adjusting the workflow or managing resources efficiently rather than directly relating to the timing overlap of construction phases.
