engineering letter of guarantee, also known as a "letter of guarantee for engineers", is a type of guarantee letter commonly used in the field of engineering and construction. It is a written commitment issued by a guarantor, often a bank or a financial institution, to ensure the performance and obligations of one party, usually the contractor, to another party, typically the project owner or the employer.

The letter of guarantee serves as a financial assurance that protects the interests of the beneficiary (the project owner) by providing a guarantee that the contractor will fulfill their contractual obligations. In the event of a breach of contract or failure to perform by the contractor, the beneficiary can call upon the guarantor to honor the terms of the letter of guarantee and provide compensation or fulfill the obligations specified in the guarantee.
