Bonding is not insurance, it is a financial relationship. Suretyship is the pledge of one party (the Surety) to another party (the Obligee) that a third party (the Principal) will faithfully perform its obligations in an underlying contract between the Obligee and the Principal. The Surety guarantees that a contractor will build a project for the owner in accordance with the construction contract. Project owners obtain a number of benefits from surety bonds, the most important is, assurance the project will be completed and the completed project will be free of supplier and subcontractor liens.
