Adjudication #

A process for resolving disputes in construction contracts where an independent third party, known as the adjudicator, makes a decision that is binding on the parties involved.

Advance Payment #

A payment made by the employer to the contractor before work begins on a construction project. This is usually done to help the contractor cover initial costs such as mobilization and materials.

Arbitration #

A method of dispute resolution in construction contracts where an independent arbitrator makes a decision that is legally binding on the parties involved. It is a more formal process than adjudication and is often used when disputes cannot be resolved through negotiation.

Bill of Quantities (BoQ) #

A document used in construction contracts that lists all the items of work to be completed on a project along with their quantities and prices. It helps in determining the total cost of the project.

Change Order #

A written agreement between the parties involved in a construction contract to change the scope of work, time, or cost of the project. Change orders are used to document any modifications to the original contract.

Claim #

A demand by one party in a construction contract for compensation or relief due to a breach of contract or other issues. Claims can be related to delays, defects, or additional work not covered in the original contract.

Collateral Warranty #

A legal document in construction contracts that provides a third party, such as a tenant or funder, with a direct contractual relationship with the contractor or consultant. This ensures that the third party has rights under the contract.

Compensation paid by one party to the other in a construction contract for delays in completing the project. Delay damages are usually specified in the contract and are intended to cover the costs incurred due to the delay.

The process of resolving conflicts and disagreements between the parties involved in a construction contract. This can include negotiation, mediation, adjudication, arbitration, or litigation.

An agreement in a construction contract to extend the time for completing the works due to delays caused by unforeseen circumstances, such as adverse weather or changes in the scope of work.

Final Account #

A document prepared at the end of a construction project that details all the costs incurred, including variations, claims, and additional work. The final account is used to calculate the final payment due to the contractor.

Frustration of Contract #

A legal doctrine that allows a construction contract to be terminated if unforeseen events make it impossible to complete the project. Frustration of contract can occur due to events such as war, natural disasters, or government regulations.
