D-430 Proposal Bond – Design Build

The EJCDC® D-430 Proposal Bond is a legal document used by a surety to guarantee that a Proposer will enter into a construction contract with the Owner if awarded the project. ​ If the Proposer defaults by failing to execute the contract or provide required performance and payment bonds, the penal sum of the bond is forfeited to the Owner as compensation. ​ The document includes detailed guidelines for its use, editing, and legal provisions, and is governed by the 2026 EJCDC® Design-Build Series License Agreement. ​
