Additional Work Under A Construction Contract: Practical Advice On How To Avoid Disputes

Situations where a contractor performs additional work under a construction contract occur often in practice. In such a situation various questions arise. Is the contractor obliged to perform additional work? Does he or she have the right to demand payment for it and how can he or she reduce the potential risks of not being paid? Let's examine these questions.

Let's begin with an example from our recent experience.

A Contractor concludes a contract for construction with a Customer, the terms of which establish that he will receive a fixed sum in return for the completion of a certain amount of work. In the course of performing the work, the Contractor discovers that the project documentation does not contain a certain necessary amount of work (for example, instructions are missing regarding a certain aspect of the work, meaning that the facility cannot be constructed). Not all the costs associated with the work in progress were included in the estimate. Despite the Contractor having given notice to the Customer of the defects in the project documents and not receiving the consent of the Customer for the provision of additional work and an increase in the estimated cost of construction, the Contractor completed most of the additional work in order to complete the project on time. The Contractor only stops working when it becomes clear that the Customer will not give his consent for the performance of additional work. Thus a substantial amount of additional work has already been done. The Customer subsequently refuses to sign the act of acceptance for the additional work and pay for it. The Contractor then in view of the Customer's refusal to pay for the additional work approaches the court.

How to protect against similar situations? This question never ceases to be important. And so we must first seek to understand what is 'additional work'?

What is the additional work and how can an agreement with the customer be regarding them?

In Kazakhstan it is often encountered in practice that in the course of construction it is necessary to perform certain operations which are not included in the project documents, the implementation of which will cause an increase in the estimated cost of construction and without which the continuance of further construction will be impossible. At the same time the mere fact that additional work has been performed by the contractor does not in itself constitute a circumstance giving rise to an obligation on the part...
