Managing Risk in Complex Construction Projects

Construction projects rely heavily on professional design, engineering, and supervisory services. Where failures occur in those services, the resulting financial exposure can be significant, particularly on large or technically complex developments. Architects & Engineers Professional Indemnity (A&E PI) insurance is designed to indemnify design or contractor firms against legal liability arising from errors, omissions, or negligent acts committed in the course of professional activities.

Such liabilities commonly arise from:

• design work,
• engineering calculations,
• specifications,
• feasibility studies,
• project coordination, and
• supervisory activity.

As Bence Széles, PI Practice Leader summarized, “in practice, professional errors may lead not only to financial loss, but also to delays, remedial works, regulatory issues, or third-party claims arising long after project completion. As a result, A&E PI coverage increasingly needs to reflect the operational realities of modern construction projects.”

Typical areas of consideration when structuring A&E PI include:

• long-tail exposure arising after completion of design work,
• allocation of responsibility between contractors and consultants,
• coverage for remediation-related costs linked to professional negligence,
• project-specific aggregate limits for major developments.

Both annual policies and project-specific policies structures may be used, depending on the nature and scale of the project.

The overall purpose of A&E PI is to protect design or contractor firms firms against liabilities arising from faulty architect or engineering services, while supporting continuity of operations and financial stability following a claim.

Loss Scenario: Structural Design Error and Remedial Works

An engineering company incorrectly calculates the load capacity of a concrete slab in a residential development. The error is identified after completion during a safety inspection. Although no collapse occurs, structural reinforcement works become necessary, requiring partial dismantling and reconstruction of completed interior sections.

Potential claim components may include:

• professional negligence allegations,
• remedial and repair costs without property damage,
• third-party financial loss,
• legal defence costs.

Where the underlying cause of the loss is a professional design error, A&E PI insurance may respond to associated liabilities, subject to policy terms and conditions.
