Construction bonds, or surety bonds, are security instruments that mitigate risk for clients, developers, contractors and their supply chains.
They are formal agreements involving three parties:
usually a bank or insurance firm
the named beneficiary
normally contractors, consultants, subcontractors and suppliers.
The surety guarantees to make a predetermined payment to the project owner or client should the principal fail to perform or fulfil their contractual obligations. Surety bonds broadly fall into two categories: conditional, and on-demand.
The beneficiary has to prove that the principal has failed to meet their contractual obligations, and as a direct result they themselves have incurred financial losses. Some conditional bonds will only be honoured if all of the conditions are met; most beneficiaries are therefore reluctant to accept some conditional bonds, and often ask the legal teams involved to revise the terms to be more equitable.
Conditional bonds typically take the form of a retention bond, which is issued by the surety to a specified client to guarantee and pay an agreed sum in the event of non-performance or principal insolvency. This improves the principal's liquidity, and safeguards retention payments to the supply chain should it become insolvent.
With these bonds, the beneficiary simply has to submit the bond and demand payment from the surety. It is not obliged to provide any evidence that the principal has breached or failed to fulfil its contractual obligations, so most principals are therefore reluctant to sign up to terms and conditions with on-demand clauses.
On-demand bonds typically take one of the following forms.
this is issued by the surety to guarantee that a bidder will enter into a formal contract if its bid offer is accepted. If not, the surety will pay the client the sum mentioned in the bond. Such a bond is normally applied to cost- and schedule-sensitive bids, and ensures only committed tenderers participate in the process.
at times clients issue advance payments to suppliers and service providers, and this bond will safeguard these in the event of the non-performance or insolvency of either. The bond helps minimise risks associated with inflation, securing fixed commodity prices during hyperinflation, as well as risks associated with currency movements for materials procured from abroad, and helps the principal to accelerate service provision.
the surety guarantees to reimburse an agreed sum to the client in the event of performance failure or the principal's insolvency. It is ideal for helping principals to accelerate progress on a project, as well as reducing the client's financial risk.
principals – usually developers – take out a bond in favour of the client – often local authorities – that guarantees a prescribed sum be paid in the event of a failure to hand over roads and drainage services in a condition that fulfils Building Regulations. The bond lowers the client's financial risk exposure.
this is issued to guarantee payments made to the principal for off-site materials, commonly when a substantial portion of the work has to be completed off site and the beneficiary needs to minimise exposure to financial risk if the principal or supplier falls into liquidation. The off-site materials have to be handled as the conditions in the bond agreement specify.
We have recently witnessed the emergence of a third category of bonds that is yet to gain a formal nomenclature, but which share traits of both conditional and on-demand bonds. As construction procurement models keep evolving and now tend to prefer collaborative approaches, we are likely to see more such forms dominate bond markets as their terms and conditions are often equitable and more palatable for beneficiaries and principals alike.
These bonds typically take the form of a performance bond, which is issued by the surety to guarantee performance by the named principal. In the event of performance failure, the named client will be paid the prescribed amount, usually ten per cent of the contract sum. This reduces the client's financial risk as it is able to fund the cost to replace the principal with the bond payment.
Different forms of contract also have different provisions for construction bonds, as some examples from the UK demonstrate.
the contract particulars contain provisions for using performance, retention, advance payment and bid bonds. These particulars are drafted by the beneficiary, so tend to be on-demand bonds. The principalâ€™s failure to produce the specified bond is deemed a serious breach and may lead to contractual termination.
secondary option clauses for bonds under this form of contract are the X13 performance bond, X14 advance payment bond and X16 retention bond. Bond conditions are specified in the works information section of the contract; failure to provide the bond on the project manager's instruction will lead to the withholding of a quarter of payment due and, eventually, to contractual termination.
these conditions require the contractor or supplier to provide performance security bonds under clause 18. The bond specifications are outlined in the appendix and the form of bond annexed to the conditions of contract. Provision of the bond is deemed a condition precedent to any obligation the employer has to make payments that might otherwise be due under this contract.
Bond wordings and forms are mostly set by the Association of British Insurers. Internationally, FIDIC is the contract form used on most major World Bank projects. It recommends the use of construction bonds when contracting suppliers and contractors, but discourages the use of surety bonds when appointing consultants.
Costs are determined by many factors, key among which is the financial status of the performer or principal taking out the bond: firms with strong balance sheets and high credit ratings will secure bonds at lower costs than peers with weaker balance sheets and lower credit scores.
The cost of surety bonds is also determined by the risk levels associated with:
Bond costs are therefore difficult to estimate. In the UK they tend to vary between one and a half and eight per cent of the bond value, with a flat fee ranging from £700 to £1,500. In some circumstances, performers and service providers tend to be reluctant to issue bonds as the full bond value is marked against their overdraft facility, which can have a detrimental effect on their balance sheet and credit score ratings.
Surety bonds, when correctly understood and used, are tools that can effectively mitigate financial risk for clients and supply chains.
