Under the RIAI (Royal Institute of the Architects of Ireland) standard forms of building contract in Ireland, Performance Bonds and Warranty Bonds are often required for certain projects, especially those of significant value or involving public or institutional clients. Here’s a breakdown of the types and context in which they apply:
🔐 Types of Bonds under RIAI Contracts
1. Performance Bond
Purpose: To provide financial security to the employer (client) in case the contractor fails to fulfil their contractual obligations.
Typical Form: A Performance Bond is usually executed by a third-party surety (e.g. a bank or insurance company).
Amount: Commonly 10% of the contract sum (but this can vary).
Duration: Typically valid until Practical Completion or a specified period thereafter.
Relevant RIAI Clause: Not automatically included in RIAI contracts—must be added as a supplemental condition or required in the Schedule or Preliminaries.
2. Advance Payment Bond (less common)
Purpose: Used when the contractor receives an advance payment. This bond guarantees repayment if the contractor defaults.
Usually seen in: Public works or contracts with advance mobilisation costs.
Not standard in RIAI contracts but may be incorporated if advance payments are involved.
3. Retention Bond
Purpose: To replace cash retention; allows the contractor to receive full payments during the project while still providing security to the client.
Issued by: Bank or surety.
Commonly introduced when clients prefer not to hold retention monies.
🧾 Collateral Warranties (Not Bonds but Related)
While not a "bond" per se, collateral warranties are commonly required alongside RIAI contracts from:
Contractors
Subcontractors
Designers They are used to give third parties (like funders, tenants, or purchasers) a direct contractual relationship with the parties carrying out the work or design.
🏛️ RIAI Forms & Public Works
In public sector projects, RIAI contracts may be replaced by Public Works Contracts (PWC), where performance bonds are mandatory and more rigidly defined (usually in standard DoE templates).
📌 Summary Table
Bond Type | Typical Use | Required? | Notes |
Performance Bond | Security against contractor default | Often, by agreement | Usually 10% of contract sum |
Advance Payment Bond | Protects client’s advance payment | Rare in RIAI contracts | May be included if mobilisation advance is paid |
Retention Bond | Replaces cash retention | Optional, by agreement | Useful for contractor cash flow |
Collateral Warranty | Provides rights to third parties | Yes, in many cases | Not a bond, but related to project risk allocation |
In Ireland, a contractor typically obtains a Performance Bond or Warranty Bond through a surety provider—usually a bank, an insurance company, or a specialist bonding company. Here’s a friendly, professional breakdown of how the process works and what’s usually involved:
🛠️ Steps to Obtain a Warranty Bond / Performance Bond
1. Check the Contract Requirements
Review the RIAI or PWC contract to confirm if a Performance Bond is required.
Check the percentage of the bond (commonly 10% of the contract sum) and validity period (often up to Practical Completion or beyond).
2. Engage a Bonding Provider
Contractors can approach:
Their main bank (e.g. AIB, BOI, Permanent TSB)
An insurance broker (e.g. Willis Towers Watson, Arachas, or Lockton)
A specialist surety provider (e.g. Surety Bonds Ireland, Surety Solutions)
It’s often helpful to work through a broker who understands construction and can shop the market.
3. Prepare Required Documentation
Expect to be asked for:
Recent financial statements (2–3 years)
Company accounts, cash flow, and turnover
Details of the contract/project
Record of past project performance
List of ongoing obligations
Personal guarantees (for SMEs or new contractors)
4. Underwriting & Approval
The surety provider assesses the financial health, track record, and capacity of the contractor.
This is like a credit check—more established contractors with clean financials get quicker approvals and better rates.
5. Bond Issuance
Once approved, the surety will issue the bond document, naming:
The beneficiary (usually the employer or client)
The principal (the contractor)
The surety (the bonding company)
The bond amount and expiry date
The original bond is usually handed to the Employer’s Representative or Architect under the contract.
💶 What Does It Cost?
Typical Premium: Between 0.5% and 2% of the bond value (depending on risk, credit history, and project size).
Example: A €200,000 bond might cost €1,000–€4,000 for the year.
📜 Common Bond Types Issued in Ireland
Bond Type | Issued By | Typical Value | Used When |
Performance Bond | Bank / Surety Company | 10% of contract sum | Contractor must guarantee delivery of contract |
Retention Bond | Insurance or Bank | Replaces 5% retention | Contractor wants cash flow during project |
Surety or Bank | Matches advance | Contractor receives upfront payment | |
Collateral Warranty | Direct from contractor/designer | N/A | Client or funder needs third-party rights |
