A multinational construction company tasked with building a new high$-$rise commercial complex

in a downtown urban area. The company is under contract to complete the project within a

specified budget and timeline while ensuring the highest standards of construction quality.

During the project execution, the project team encounters the following challenges:

Challenge X: An unexpected delay in obtaining the necessary permits and approvals from local

authorities threatens to push back the project schedule.

Challenge Y: A significant portion of the construction materials originally specified in the

project plan experiences a sudden price increase in the market, potentially straining the project

budget.

Challenge Z: During the construction phase, unforeseen design modifications are required to

meet evolving environmental compliance standards, leading to potential adjustments in the

construction process.
