What are Extensions of Times?

Extension of time, or EOT, is a request made by a contractor when unexpected events cause delays in a construction project. These events can be classified into three categories: delays caused by the contractor, delays caused by the client or their consultants, and uncontroll external delays.

In cases of delays caused by the contractor, such as poor productivity or mismanagement, the contractor is not eligible for an EOT. However, if the delays are caused by the client, such as payment or approval delays, the contractor has the right to request an EOT and may also be entitled to a prolongation claim for the additional costs incurred.

Uncontrollable external delays, such as adverse weather or civil unrest, are also eligible for an EOT. In these cases, the contractor may also be entitled to a loss of profits claim. It is important for the client to follow the correct procedure for deducting liquidated damages in these situations.

As a quantity surveyor, it is important to focus on all events that may impact the project schedule and to consider the potential for EOT claims in cases of delays.

Extension of time (EOT) claims are a common occurrence in the construction industry and often result in conflicts between contractors and clients. EOT claims are typically made by contractors when delays occur on a project and are usually handled by a quantity surveyor.

These claims consist of a delay analysis, calculations and evidence for time-related costs, and relevant communications and correspondences. There are three main categories of delay events: those caused by the contractor, those prompted by the client or their consultants, and external delays that are unexpected and uncontroll.

Delay analysis is important for the preparation of EOT claims as it helps contractors compare the original timeline with the deviated timeline and calculate the number of days delayed due to the delay event or events.

There are several methods for conducting delay analysis, including the impacted as-planned method, collapsed as-built method, and time impact analysis. It is important for contractors to properly document and present EOT claims in order to avoid unreasonable reductions or denials by clients
