The Importance of Collateral Warranties in Construction Projects

In the construction industry, the intricate web of contractual relationships often leaves parties wondering about the extent of their legal responsibilities. The recent case of Multiplex Construction Europe Ltd v Bathgate Realisations Civil Engineering Ltd & Ors [2021] EWHC 590 (TCC) underscores the critical importance of understanding the limitations of duty of care in tort, and highlights the necessity of collateral warranties and third-party rights.

Case Background

Multiplex engaged Bathgate for the 100 Bishopsgate project in London, assigning them design responsibilities for both the concrete core and the temporary slipform rig works. Bathgate, in turn, subcontracted RNP, a consultancy, to perform “Category 3 checks” on the design. However, post-liquidation of Bathgate, defects in the slipform rig emerged compelling Multiplex to replace the rig and undertake additional remedial actions. Multiplex then sought to claim these costs from RNP’s insurers under the Third Parties (Rights Against Insurers) Act 2010.

Legal Question

The central question was whether RNP owed any duty of care to Multiplex regarding the Category 3 checks provided to Bathgate.

Court’s Decision

Mr. Justice Fraser concluded that RNP did not owe a duty of care to Multiplex. This decision was reached by applying several legal tests:

  1. Assumption of Responsibility Test: Under the principles from Hedley Byrne & Co v Heller & Partners Ltd and Henderson v Merrett Syndicates Ltd, it was determined that RNP had not assumed responsibility towards Multiplex.
  2. Three-Part Test: The criteria of reasonable foreseeability of economic loss, proximity, and fairness, justice, and reasonableness from Caparo Industries plc v Dickman were not met.
  3. Negligent Misstatement: There was no evidence that RNP had made any misstatements to Multiplex.

Key Points from the Judgment

  • No Direct Contractual Link: There was no direct contractual relationship between RNP and Multiplex. Bathgate’s insolvency did not create a liability for RNP.
  • Complex Contractual Structure: The court noted the extensive and complex contractual framework of the project, which separated Bathgate’s and RNP’s roles from Multiplex.
  • Scope of Responsibility: RNP’s role was limited to verifying Bathgate’s designs for compliance with British Standards, with no direct services or responsibilities to Multiplex.
  • Reasonable Businessman Perspective: It was deemed inconceivable that RNP would voluntarily assume responsibility towards the main contractor or other project participants beyond their direct contract.

Implications for the Construction Industry

This case serves as a powerful reminder of the difficulties in pursuing tort claims against third parties in the absence of direct contractual relationships. The judgment reinforces the need for main contractors and employers to secure collateral warranties and third-party rights to ensure all potential risks are managed appropriately.

Practical Takeaways

  • Collateral Warranties and Third-Party Rights: Ensure comprehensive collateral warranties and third-party rights are in place for all significant roles in a project to avoid gaps in responsibility.
  • Review Contractual Structures: Regularly review and understand the contractual relationships within a project to identify potential risks and liabilities.
  • Limited Roles and Responsibilities: Recognise that parties with limited roles and specific responsibilities, like RNP, may not be liable for broader project issues.

In conclusion, Multiplex v Bathgate highlights the importance of robust contractual frameworks and the limitations of tort claims in complex construction projects. It also underscores the necessity for employers and main contractors to proactively manage risks through detailed and well-structured contractual agreements.
