While large construction bonds can be easier to obtain than smaller ones, the determining factor is the nature of the commitment rather than the dollar amount. Performance and payment bonds ensure a construction project is completed per contract and subcontractors are paid, with the unpaid contract amount providing security even if the contractor fails. In contrast, wage and welfare bonds guarantee future union payments, making them riskier without collateral if the contractor becomes insolvent, as the surety would have to pay claims directly without reimbursement. As such, smaller bonds that ensure future financial obligations like wage and welfare bonds require full collateral due to the difficult nature of the commitment.
