Prolongation claims are typically made when delays in a construction project result in additional costs due to the extension of time required to complete the project.

These claims seek compensation for the extra expenses incurred as a result of delays that were beyond the contractor's control.

Common causes of prolongation claims include:

• unforeseen site conditions,
• changes in project scope, or
• delays caused by external factors such as weather or regulatory issues.

Prolongation claims can be complex, as they often involve a detailed analysis of the project schedule, costs, and contract terms.

Contractors must provide comprehensive documentation, including:

• evidence of the delays,
• the associated costs, and
• how the delays impacted the project timeline.

Resolving prolongation claims often requires negotiation and, in some cases, arbitration or litigation.

Proper management of prolongation claims is essential for ensuring that all parties are fairly compensated for delays, which helps mitigate financial risks and ensures that projects can continue moving forward despite disruptions.
