Definition:Erection all-risk insurance (EAR)
🏗️ Erection all-risk insurance (EAR) is a specialized engineering insurance product designed to cover losses arising during the installation, erection, and testing of machinery, plant, and steel structures at construction and industrial sites. While its counterpart, contractors' all-risk (CAR) insurance, focuses on civil engineering and building construction, EAR is tailored to projects dominated by mechanical and electrical erection work — power plants, refineries, manufacturing facilities, wind farms, and telecommunications infrastructure. The coverage typically operates on an all-risk basis, meaning it protects against all causes of physical loss or damage unless specifically excluded.
⚙️ An EAR policy generally comprises multiple sections. Section I covers material damage to the works under erection, including equipment and materials stored on-site. Section II provides third-party liability cover for bodily injury and property damage arising from the erection activities. Many policies also include extensions for surrounding property, existing structures, and the principal's own plant. The policy incepts when materials arrive at the project site and typically runs through mechanical completion and a testing or commissioning period, after which the asset transitions to a permanent operational property or machinery breakdown policy. Underwriting EAR risks demands specialized engineering expertise — insurers assess factors such as the type of machinery being erected, the experience of the contractor, site conditions, seismic exposure, and the adequacy of project management. Munich Re, Swiss Re, and a number of Lloyd's syndicates are prominent participants in this market globally, with significant portfolios in Asia, the Middle East, and emerging markets where infrastructure investment drives demand.
💡 The distinction between EAR and CAR matters in practice because the risk profile of mechanical and electrical erection differs fundamentally from civil construction. Erection projects involve expensive, precision-engineered components where a single assembly error or transit damage incident can produce a loss disproportionate to the overall project value. Defects liability and maintenance extensions are common, covering the insured for a specified period after completion during which latent erection faults may manifest. For large-scale energy and industrial projects, EAR coverage is frequently placed alongside delay in start-up (DSU) insurance, which compensates the project owner for revenue losses if erection delays push back the commercial operation date. Across markets, the EAR product remains a cornerstone of engineering insurance, and its terms are often based on the Munich Re model wording that has served as the de facto global standard for decades.
